# nodemon
nodemon is a tool that helps develop Node.js based applications by automatically restarting the node application when file changes in the directory are detected.
nodemon does **not** require *any* additional changes to your code or method of development. nodemon is a replacement wrapper for `node`. To use `nodemon`, replace the word `node` on the command line when executing your script.
[![NPM version](https://badge.fury.io/js/nodemon.svg)](https://npmjs.org/package/nodemon)
[![Backers on Open Collective](https://opencollective.com/nodemon/backers/badge.svg)](#backers) [![Sponsors on Open Collective](https://opencollective.com/nodemon/sponsors/badge.svg)](#sponsors)
# Installation
Either through cloning with git or by using [npm](http://npmjs.org) (the recommended way):
```bash
npm install -g nodemon # or using yarn: yarn global add nodemon
```
And nodemon will be installed globally to your system path.
You can also install nodemon as a development dependency:
```bash
npm install --save-dev nodemon # or using yarn: yarn add nodemon -D
```
With a local installation, nodemon will not be available in your system path or you can't use it directly from the command line. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as `npm start`) or using `npx nodemon`.
# Usage
nodemon wraps your application, so you can pass all the arguments you would normally pass to your app:
```bash
nodemon [your node app]
```
For CLI options, use the `-h` (or `--help`) argument:
```bash
nodemon -h
```
Using nodemon is simple, if my application accepted a host and port as the arguments, I would start it as so:
```bash
nodemon ./server.js localhost 8080
```
Any output from this script is prefixed with `[nodemon]`, otherwise all output from your application, errors included, will be echoed out as expected.
You can also pass the `inspect` flag to node through the command line as you would normally:
```bash
nodemon --inspect ./server.js 80
```
If you have a `package.json` file for your app, you can omit the main script entirely and nodemon will read the `package.json` for the `main` property and use that value as the app ([ref](https://github.com/remy/nodemon/issues/14)).
nodemon will also search for the `scripts.start` property in `package.json` (as of nodemon 1.1.x).
Also check out the [FAQ](https://github.com/remy/nodemon/blob/master/faq.md) or [issues](https://github.com/remy/nodemon/issues) for nodemon.
## Automatic re-running
nodemon was originally written to restart hanging processes such as web servers, but now supports apps that cleanly exit. If your script exits cleanly, nodemon will continue to monitor the directory (or directories) and restart the script if there are any changes.
## Manual restarting
Whilst nodemon is running, if you need to manually restart your application, instead of stopping and restart nodemon, you can type `rs` with a carriage return, and nodemon will restart your process.
## Config files
nodemon supports local and global configuration files. These are usually named `nodemon.json` and can be located in the current working directory or in your home directory. An alternative local configuration file can be specified with the `--config <file>` option.
The specificity is as follows, so that a command line argument will always override the config file settings:
- command line arguments
- local config
- global config
A config file can take any of the command line arguments as JSON key values, for example:
```json
{
"verbose": true,
"ignore": ["*.test.js", "**/fixtures/**"],
"execMap": {
"rb": "ruby",
"pde": "processing --sketch={{pwd}} --run"
}
}
```
The above `nodemon.json` file might be my global config so that I have support for ruby files and processing files, and I can run `nodemon demo.pde` and nodemon will automatically know how to run the script even though out of the box support for processing scripts.
A further example of options can be seen in [sample-nodemon.md](https://github.com/remy/nodemon/blob/master/doc/sample-nodemon.md)
### package.json
If you want to keep all your package configurations in one place, nodemon supports using `package.json` for configuration.
Specify the config in the same format as you would for a config file but under `nodemonConfig` in the `package.json` file, for example, take the following `package.json`:
```json
{
"name": "nodemon",
"homepage": "http://nodemon.io",
"...": "... other standard package.json values",
"nodemonConfig": {
"ignore": ["**/test/**", "**/docs/**"],
"delay": 2500
}
}
```
Note that if you specify a `--config` file or provide a local `nodemon.json` any `package.json` config is ignored.
*This section needs better documentation, but for now you can also see `nodemon --help config` ([also here](https://github.com/remy/nodemon/blob/master/doc/cli/config.txt))*.
## Using nodemon as a module
Please see [doc/requireable.md](doc/requireable.md)
## Using nodemon as child process
Please see [doc/events.md](doc/events.md#Using_nodemon_as_child_process)
## Running non-node scripts
nodemon can also be used to execute and monitor other programs. nodemon will read the file extension of the script being run and monitor that extension instead of `.js` if there's no `nodemon.json`:
```bash
nodemon --exec "python -v" ./app.py
```
Now nodemon will run `app.py` with python in verbose mode (note that if you're not passing args to the exec program, you don't need the quotes), and look for new or modified files with the `.py` extension.
### Default executables
Using the `nodemon.json` config file, you can define your own default executables using the `execMap` property. This is particularly useful if you're working with a language that isn't supported by default by nodemon.
To add support for nodemon to know about the `.pl` extension (for Perl), the `nodemon.json` file would add:
```json
{
"execMap": {
"pl": "perl"
}
}
```
Now running the following, nodemon will know to use `perl` as the executable:
```bash
nodemon script.pl
```
It's generally recommended to use the global `nodemon.json` to add your own `execMap` options. However, if there's a common default that's missing, this can be merged in to the project so that nodemon supports it by default, by changing [default.js](https://github.com/remy/nodemon/blob/master/lib/config/defaults.js) and sending a pull request.
## Monitoring multiple directories
By default nodemon monitors the current working directory. If you want to take control of that option, use the `--watch` option to add specific paths:
```bash
nodemon --watch app --watch libs app/server.js
```
Now nodemon will only restart if there are changes in the `./app` or `./libs` directory. By default nodemon will traverse sub-directories, so there's no need in explicitly including sub-directories.
Nodemon also supports unix globbing, e.g `--watch './lib/*'`. The globbing pattern must be quoted. For advanced globbing, [see `picomatch` documentation](https://github.com/micromatch/picomatch#advanced-globbing), the library that nodemon uses through `chokidar` (which in turn uses it through `anymatch`).
## Specifying extension watch list
By default, nodemon looks for files with the `.js`, `.mjs`, `.coffee`, `.litcoffee`, and `.json` extensions. If you use the `--exec` option and monitor `app.py` nodemon will monitor files with the extension of `.py`. However, you can specify your own list with the `-e` (or `--ext`) switch like so:
```bash
nodemon -e js,pug
```
Now nodemon will restart on any changes to files in the directory (or subdirectories) with the extensions `.js`, `.pug`.
## Ignoring files
By default, nodemon will only restart when a `.js` JavaScript file changes. In some cases you will want to ignore some specific files, directories or file patterns, to prevent nodemon from prematurely restarting your application.
This can be done via the command line:
```bash
nodemon --ignore lib/ --ignore tests/
```
Or specific files can be ignored:
```bash
nodemon --ignore lib/app.js
```
Patterns can also be ignored (but be sure to quote the arguments):
```bash
nodemon --ignore 'lib/*.js'
```
**Important** the ignore rules are patterns matched to the full absolute path, and this determines how many files are monitored. If using a wild card glob pattern, it needs to be used as `**` or omitted entirely. For example, `nodemon --ignore '**/test/**'` will work, whereas `--ignore '*/test/*'` will not.
Note that by default, nodemon will ignore the `.git`, `node_modules`, `bower_components`, `.nyc_output`, `coverage` and `.sass-cache` directories and *add* your ignored patterns to the list. If you want to indeed watch a directory like `node_modules`, you need to [override the underlying default ignore rules](https://github.com/remy/nodemon/blob/master/faq.md#overriding-the-underlying-default-ignore-rules).
## Application isn't restarting
In some networked environments (such as a container running nodemon reading across a mounted drive), you will need to use the `legacyWatch: true` which enables Chokidar's polling.
Via the CLI, use either `--legacy-watch` or `-L` for short:
```bash
nodemon -L
```
Though this should be a last resort as it will poll every file it can find.
## Delaying restarting
In some situations, you may want to wait until a number of files have changed. The timeout before checking for new file changes is 1 second. If you're uploading a number of files and it's taking some number of seconds, this could cause your app to restart multiple times unnecessarily.
To add an extra throttle, or delay restarting, use the `--delay` command:
```bash
nodemon --delay 10 server.js
```
For more precision, milliseconds can be specified. Either as a float:
```bash
nodemon --delay 2.5 server.js
```
Or using the time specifier (ms):
```bash
nodemon --delay 2500ms server.js
```
The delay figure is number of seconds (or milliseconds, if specified) to delay before restarting. So nodemon will only restart your app the given number of seconds after the *last* file change.
If you are setting this value in `nodemon.json`, the value will always be interpreted in milliseconds. E.g., the following are equivalent:
```bash
nodemon --delay 2.5
{
"delay": 2500
}
```
## Gracefully reloading down your script
It is possible to have nodemon send any signal that you specify to your application.
```bash
nodemon --signal SIGHUP server.js
```
Your application can handle the signal as follows.
```js
process.on("SIGHUP", function () {
reloadSomeConfiguration();
process.kill(process.pid, "SIGTERM");
})
```
Please note that nodemon will send this signal to every process in the process tree.
If you are using `cluster`, then each workers (as well as the master) will receive the signal. If you wish to terminate all workers on receiving a `SIGHUP`, a common pattern is to catch the `SIGHUP` in the master, and forward `SIGTERM` to all workers, while ensuring that all workers ignore `SIGHUP`.
```js
if (cluster.isMaster) {
process.on("SIGHUP", function () {
for (const worker of Object.values(cluster.workers)) {
worker.process.kill("SIGTERM");
}
});
} else {
process.on("SIGHUP", function() {})
}
```
## Controlling shutdown of your script
nodemon sends a kill signal to your application when it sees a file update. If you need to clean up on shutdown inside your script you can capture the kill signal and handle it yourself.
The following example will listen once for the `SIGUSR2` signal (used by nodemon to restart), run the clean up process and then kill itself for nodemon to continue control:
```js
// important to use `on` and not `once` as nodemon can re-send the kill signal
process.on('SIGUSR2', function () {
gracefulShutdown(function () {
process.kill(process.pid, 'SIGTERM');
});
});
```
Note that the `process.kill` is *only* called once your shutdown jobs are complete. Hat tip to [Benjie Gillam](http://www.benjiegillam.com/2011/08/node-js-clean-restart-and-faster-development-with-nodemon/) for writing this technique up.
## Triggering events when nodemon state changes
If you want growl like notifications when nodemon restarts or to trigger an action when an event happens, then you can either `require` nodemon or add event actions to your `nodemon.json` file.
For example, to trigger a notification on a Mac when nodemon restarts, `nodemon.json` looks like this:
```json
{
"events": {
"restart": "osascript -e 'display notification \"app restarted\" with title \"nodemon\"'"
}
}
```
A full list of available events is listed on the [event states wiki](https://github.com/remy/nodemon/wiki/Events#states). Note that you can bind to both states and messages.
## Pipe output to somewhere else
```js
nodemon({
script: ...,
stdout: false // important: this tells nodemon not to output to console
}).on('readable', function() { // the `readable` event indicates that data is ready to pick up
this.stdout.pipe(fs.createWriteStream('output.txt'));
this.stderr.pipe(fs.createWriteStream('err.txt'));
});
```
## Using nodemon in your gulp workflow
Check out the [gulp-nodemon](https://github.com/JacksonGariety/gulp-nodemon) plugin to integrate nodemon with the rest of your project's gulp workflow.
## Using nodemon in your Grunt workflow
Check out the [grunt-nodemon](https://github.com/ChrisWren/grunt-nodemon) plugin to integrate nodemon with the rest of your project's grunt workflow.
## Pronunciation
> nodemon, is it pronounced: node-mon, no-demon or node-e-mon (like pokémon)?
Well...I've been asked this many times before. I like that I've been asked this before. There's been bets as to which one it actually is.
The answer is simple, but possibly frustrating. I'm not saying (how I pronounce it). It's up to you to call it as you like. All answers are correct :)
## Design principles
- Fewer flags is better
- Works across all platforms
- Fewer features
- Let individuals build on top of nodemon
- Offer all CLI functionality as an API
- Contributions must have and pass tests
Nodemon is not perfect, and CLI arguments has sprawled beyond where I'm completely happy, but perhaps it can be reduced a little one day.

Typically the options to control nodemon are passed in via the CLI and are
listed under: nodemon --help options
nodemon can also be configured via a local and global config file:
* $HOME/nodemon.json
* $PWD/nodemon.json OR --config <file>
* nodemonConfig in package.json
All config options in the .json file map 1-to-1 with the CLI options, so a
config could read as:
{
"ext": "*.pde",
"verbose": true,
"exec": "processing --sketch=game --run"
}
There are a limited number of variables available in the config (since you
could use backticks on the CLI to use a variable, backticks won't work in
the .json config).
* {{pwd}} - the current directory
* {{filename}} - the filename you pass to nodemon
For example:
{
"ext": "*.pde",
"verbose": true,
"exec": "processing --sketch={{pwd}} --run"
}
The global config file is useful for setting up default executables
instead of repeating the same option in each of your local configs:
{
"verbose": true,
"execMap": {
"rb": "ruby",
"pde": "processing --sketch={{pwd}} --run"
}
}

Usage: nodemon [options] [script.js] [args]
Options:
--config file ............ alternate nodemon.json config file to use
-e, --ext ................ extensions to look for, ie. js,pug,hbs.
-x, --exec app ........... execute script with "app", ie. -x "python -v".
-w, --watch path ......... watch directory "path" or files. use once for
each directory or file to watch.
-i, --ignore ............. ignore specific files or directories.
-V, --verbose ............ show detail on what is causing restarts.
-- <your args> ........... to tell nodemon stop slurping arguments.
Note: if the script is omitted, nodemon will try to read "main" from
package.json and without a nodemon.json, nodemon will monitor .js, .mjs, .coffee,
.litcoffee, and .json by default.
For advanced nodemon configuration use nodemon.json: nodemon --help config
See also the sample: https://github.com/remy/nodemon/wiki/Sample-nodemon.json
Examples:
$ nodemon server.js
$ nodemon -w ../foo server.js apparg1 apparg2
$ nodemon --exec python app.py
$ nodemon --exec "make build" -e "styl hbs"
$ nodemon app.js -- --config # pass config to app.js

Configuration
--config <file> .......... alternate nodemon.json config file to use
--exitcrash .............. exit on crash, allows nodemon to work with other watchers
-i, --ignore ............. ignore specific files or directories
--no-colors .............. disable color output
--signal <signal> ........ use specified kill signal instead of default (ex. SIGTERM)
-w, --watch path ......... watch directory "dir" or files. use once for each
directory or file to watch
--no-update-notifier ..... opt-out of update version check
Execution
-C, --on-change-only ..... execute script on change only, not startup
--cwd <dir> .............. change into <dir> before running the script
-e, --ext ................ extensions to look for, ie. "js,pug,hbs"
-I, --no-stdin ........... nodemon passes stdin directly to child process
--spawn .................. force nodemon to use spawn (over fork) [node only]
-x, --exec app ........... execute script with "app", ie. -x "python -v"
-- <your args> ........... to tell nodemon stop slurping arguments
Watching
-d, --delay n ............ debounce restart for "n" seconds
-L, --legacy-watch ....... use polling to watch for changes (typically needed
when watching over a network/Docker)
-P, --polling-interval ... combined with -L, milliseconds to poll for (default 100)
Information
--dump ................... print full debug configuration
-h, --help ............... default help
--help <topic> ........... help on a specific feature. Try "--help topics"
-q, --quiet .............. minimise nodemon messages to start/stop only
-v, --version ............ current nodemon version
-V, --verbose ............ show detail on what is causing restarts
> Note that any unrecognised arguments are passed to the executing command.

nodemon is a utility for node, and replaces the use of the executable
node. So the user calls `nodemon foo.js` instead.
nodemon can be run in a number of ways:
`nodemon` - tries to use package.json#main property to run
`nodemon` - if no package, looks for index.js
`nodemon app.js` - runs app.js
`nodemon --arg app.js --apparg` - eats arg1, and runs app.js with apparg
`nodemon --apparg` - as above, but passes apparg to package.json#main (or
index.js)
`nodemon --debug app.js

# balanced-match
Match balanced string pairs, like `{` and `}` or `<b>` and
`</b>`. Supports regular expressions as well!
## Example
Get the first matching pair of braces:
```js
import { balanced } from 'balanced-match'
console.log(balanced('{', '}', 'pre{in{nested}}post'))
console.log(balanced('{', '}', 'pre{first}between{second}post'))
console.log(
balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre { in{nest} } post'),
)
```
The matches are:
```bash
$ node example.js
{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
{ start: 3,
end: 9,
pre: 'pre',
body: 'first',
post: 'between{second}post' }
{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
```
## API
### const m = balanced(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
object with those keys:
- **start** the index of the first match of `a`
- **end** the index of the matching `b`
- **pre** the preamble, `a` and `b` not included
- **body** the match, `a` and `b` not included
- **post** the postscript, `a` and `b` not included
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
### const r = balanced.range(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
array with indexes: `[ <a index>, <b index> ]`.
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

# brace-expansion
[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html),
as known from sh/bash, in JavaScript.
[![CI](https://github.com/juliangruber/brace-expansion/actions/workflows/ci.yml/badge.svg)](https://github.com/juliangruber/brace-expansion/actions/workflows/ci.yml)
[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)
## Example
```js
import { expand } from 'brace-expansion'
expand('file-{a,b,c}.jpg')
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
expand('-v{,,}')
// => ['-v', '-v', '-v']
expand('file{0..2}.jpg')
// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
expand('file-{a..c}.jpg')
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
expand('file{2..0}.jpg')
// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
expand('file{0..4..2}.jpg')
// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
expand('file-{a..e..2}.jpg')
// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
expand('file{00..10..5}.jpg')
// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
expand('{{A..C},{a..c}}')
// => ['A', 'B', 'C', 'a', 'b', 'c']
expand('ppp{,config,oe{,conf}}')
// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
```
## API
```js
import { expand } from 'brace-expansion'
```
### const expanded = expand(str, [options])
Return an array of all possible and valid expansions of `str`. If
none are found, `[str]` is returned.
The `options` object can provide a `max` value to cap the number
of expansions allowed. This is limited to `100_000` by default,
to prevent DoS attacks.
```js
const expansions = expand('{1..100}'.repeat(5), {
max: 100,
})
// expansions.length will be 100, not 100^5
```
Valid expansions are:
```js
;/^(.*,)+(.+)?$/
// {a,b,...}
```
A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
```js
;/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
// {x..y[..incr]}
```
A numeric sequence from `x` to `y` inclusive, with optional increment.
If `x` or `y` start with a leading `0`, all the numbers will be padded
to have equal length. Negative numbers and backwards iteration work too.
```js
;/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
// {x..y[..incr]}
```
An alphabetic sequence from `x` to `y` inclusive, with optional increment.
`x` and `y` must be exactly one character, and if given, `incr` must be a
number.
For compatibility reasons, the string `${` is not eligible for brace expansion.

# minimatch
A minimal matching utility.
This is the matching library used internally by npm.
It works by converting glob expressions into JavaScript `RegExp`
objects.
## Important Security Consideration!
> [!WARNING]
> This library uses JavaScript regular expressions. Please read
> the following warning carefully, and be thoughtful about what
> you provide to this library in production systems.
_Any_ library in JavaScript that deals with matching string
patterns using regular expressions will be subject to
[ReDoS](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS)
if the pattern is generated using untrusted input.
Efforts have been made to mitigate risk as much as is feasible in
such a library, providing maximum recursion depths and so forth,
but these measures can only ultimately protect against accidents,
not malice. A dedicated attacker can _always_ find patterns that
cannot be defended against by a bash-compatible glob pattern
matching system that uses JavaScript regular expressions.
To be extremely clear:
> [!WARNING]
> **If you create a system where you take user input, and use
> that input as the source of a Regular Expression pattern, in
> this or any extant glob matcher in JavaScript, you will be
> pwned.**
A future version of this library _may_ use a different matching
algorithm which does not exhibit backtracking problems. If and
when that happens, it will likely be a sweeping change, and those
improvements will **not** be backported to legacy versions.
In the near term, it is not reasonable to continue to play
whack-a-mole with security advisories, and so any future ReDoS
reports will be considered "working as intended", and resolved
entirely by this warning.
## Usage
```js
// hybrid module, load with require() or import
import { minimatch } from 'minimatch'
// or:
const { minimatch } = require('minimatch')
minimatch('bar.foo', '*.foo') // true!
minimatch('bar.foo', '*.bar') // false!
minimatch('bar.foo', '*.+(bar|foo)', { debug: true }) // true, and noisy!
```
## Features
Supports these glob features:
- Brace Expansion
- Extended glob matching
- "Globstar" `**` matching
- [Posix character
classes](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html),
like `[[:alpha:]]`, supporting the full range of Unicode
characters. For example, `[[:alpha:]]` will match against
`'é'`, though `[a-zA-Z]` will not. Collating symbol and set
matching is not supported, so `[[=e=]]` will _not_ match `'é'`
and `[[.ch.]]` will not match `'ch'` in locales where `ch` is
considered a single character.
See:
- `man sh`
- `man bash` [Pattern
Matching](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html)
- `man 3 fnmatch`
- `man 5 gitignore`
## Windows
**Please only use forward-slashes in glob expressions.**
Though windows uses either `/` or `\` as its path separator, only `/`
characters are used by this glob implementation. You must use
forward-slashes **only** in glob expressions. Back-slashes in patterns
will always be interpreted as escape characters, not path separators.
Note that `\` or `/` _will_ be interpreted as path separators in paths on
Windows, and will match against `/` in glob expressions.
So just always use `/` in patterns.
### UNC Paths
On Windows, UNC paths like `//?/c:/...` or
`//ComputerName/Share/...` are handled specially.
- Patterns starting with a double-slash followed by some
non-slash characters will preserve their double-slash. As a
result, a pattern like `//*` will match `//x`, but not `/x`.
- Patterns staring with `//?/<drive letter>:` will _not_ treat
the `?` as a wildcard character. Instead, it will be treated
as a normal string.
- Patterns starting with `//?/<drive letter>:/...` will match
file paths starting with `<drive letter>:/...`, and vice versa,
as if the `//?/` was not present. This behavior only is
present when the drive letters are a case-insensitive match to
one another. The remaining portions of the path/pattern are
compared case sensitively, unless `nocase:true` is set.
Note that specifying a UNC path using `\` characters as path
separators is always allowed in the file path argument, but only
allowed in the pattern argument when `windowsPathsNoEscape: true`
is set in the options.
## Minimatch Class
Create a minimatch object by instantiating the `minimatch.Minimatch` class.
```javascript
var Minimatch = require('minimatch').Minimatch
var mm = new Minimatch(pattern, options)
```
### Properties
- `pattern` The original pattern the minimatch object represents.
- `options` The options supplied to the constructor.
- `set` A 2-dimensional array of regexp or string expressions.
Each row in the
array corresponds to a brace-expanded pattern. Each item in the row
corresponds to a single path-part. For example, the pattern
`{a,b/c}/d` would expand to a set of patterns like:
[ [ a, d ]
, [ b, c, d ] ]
If a portion of the pattern doesn't have any "magic" in it
(that is, it's something like `"foo"` rather than `fo*o?`), then it
will be left as a string rather than converted to a regular
expression.
- `regexp` Created by the `makeRe` method. A single regular expression
expressing the entire pattern. This is useful in cases where you wish
to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
- `negate` True if the pattern is negated.
- `comment` True if the pattern is a comment.
- `empty` True if the pattern is `""`.
### Methods
- `makeRe()` Generate the `regexp` member if necessary, and return it.
Will return `false` if the pattern is invalid.
- `match(fname)` Return true if the filename matches the pattern, or
false otherwise.
- `matchOne(fileArray, patternArray, partial)` Take a `/`-split
filename, and match it against a single row in the `regExpSet`. This
method is mainly for internal use, but is exposed so that it can be
used by a glob-walker that needs to avoid excessive filesystem calls.
- `hasMagic()` Returns true if the parsed pattern contains any
magic characters. Returns false if all comparator parts are
string literals. If the `magicalBraces` option is set on the
constructor, then it will consider brace expansions which are
not otherwise magical to be magic. If not set, then a pattern
like `a{b,c}d` will return `false`, because neither `abd` nor
`acd` contain any special glob characters.
This does **not** mean that the pattern string can be used as a
literal filename, as it may contain magic glob characters that
are escaped. For example, the pattern `\\*` or `[*]` would not
be considered to have magic, as the matching portion parses to
the literal string `'*'` and would match a path named `'*'`,
not `'\\*'` or `'[*]'`. The `minimatch.unescape()` method may
be used to remove escape characters.
All other methods are internal, and will be called as necessary.
### minimatch(path, pattern, options)
Main export. Tests a path against the pattern using the options.
```javascript
var isJS = minimatch(file, '*.js', { matchBase: true })
```
### minimatch.filter(pattern, options)
Returns a function that tests its
supplied argument, suitable for use with `Array.filter`. Example:
```javascript
var javascripts = fileList.filter(
minimatch.filter('*.js', { matchBase: true }),
)
```
### minimatch.escape(pattern, options = {})
Escape all magic characters in a glob pattern, so that it will
only ever match literal strings.
If the `windowsPathsNoEscape` option is used, then characters are
escaped by wrapping in `[]`, because a magic character wrapped in
a character class can only be satisfied by that exact character.
Slashes (and backslashes in `windowsPathsNoEscape` mode) cannot
be escaped or unescaped.
### minimatch.unescape(pattern, options = {})
Un-escape a glob string that may contain some escaped characters.
If the `windowsPathsNoEscape` option is used, then square-brace
escapes are removed, but not backslash escapes. For example, it
will turn the string `'[*]'` into `*`, but it will not turn
`'\\*'` into `'*'`, because `\` is a path separator in
`windowsPathsNoEscape` mode.
When `windowsPathsNoEscape` is not set, then both brace escapes
and backslash escapes are removed.
Slashes (and backslashes in `windowsPathsNoEscape` mode) cannot
be escaped or unescaped.
### minimatch.match(list, pattern, options)
Match against the list of
files, in the style of fnmatch or glob. If nothing is matched, and
options.nonull is set, then return a list containing the pattern itself.
```javascript
var javascripts = minimatch.match(fileList, '*.js', { matchBase: true })
```
### minimatch.makeRe(pattern, options)
Make a regular expression object from the pattern.
## Options
All options are `false` by default.
### debug
Dump a ton of stuff to stderr.
### nobrace
Do not expand `{a,b}` and `{1..3}` brace sets.
### noglobstar
Disable `**` matching against multiple folder names.
### dot
Allow patterns to match filenames starting with a period, even if
the pattern does not explicitly have a period in that spot.
Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
is set.
### noext
Disable "extglob" style patterns like `+(a|b)`.
### nocase
Perform a case-insensitive match.
### nocaseMagicOnly
When used with `{nocase: true}`, create regular expressions that
are case-insensitive, but leave string match portions untouched.
Has no effect when used without `{nocase: true}`.
Useful when some other form of case-insensitive matching is used,
or if the original string representation is useful in some other
way.
### nonull
When a match is not found by `minimatch.match`, return a list containing
the pattern itself if this option is set. When not set, an empty list
is returned if there are no matches.
### magicalBraces
This only affects the results of the `Minimatch.hasMagic` method.
If the pattern contains brace expansions, such as `a{b,c}d`, but
no other magic characters, then the `Minimatch.hasMagic()` method
will return `false` by default. When this option set, it will
return `true` for brace expansion as well as other magic glob
characters.
### matchBase
If set, then patterns without slashes will be matched
against the basename of the path if it contains slashes. For example,
`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
### nocomment
Suppress the behavior of treating `#` at the start of a pattern as a
comment.
### nonegate
Suppress the behavior of treating a leading `!` character as negation.
### flipNegate
Returns from negate expressions the same as if they were not negated.
(Ie, true on a hit, false on a miss.)
### partial
Compare a partial path to a pattern. As long as the parts of the path that
are present are not contradicted by the pattern, it will be treated as a
match. This is useful in applications where you're walking through a
folder structure, and don't yet have the full path, but want to ensure that
you do not walk down paths that can never be a match.
For example,
```js
minimatch('/a/b', '/a/*/c/d', { partial: true }) // true, might be /a/b/c/d
minimatch('/a/b', '/**/d', { partial: true }) // true, might be /a/b/.../d
minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a
```
### windowsPathsNoEscape
Use `\\` as a path separator _only_, and _never_ as an escape
character. If set, all `\\` characters are replaced with `/` in
the pattern. Note that this makes it **impossible** to match
against paths containing literal glob pattern characters, but
allows matching with patterns constructed using `path.join()` and
`path.resolve()` on Windows platforms, mimicking the (buggy!)
behavior of earlier versions on Windows. Please use with
caution, and be mindful of [the caveat about Windows
paths](#windows).
For legacy reasons, this is also set if
`options.allowWindowsEscape` is set to the exact value `false`.
### windowsNoMagicRoot
When a pattern starts with a UNC path or drive letter, and in
`nocase:true` mode, do not convert the root portions of the
pattern into a case-insensitive regular expression, and instead
leave them as strings.
This is the default when the platform is `win32` and
`nocase:true` is set.
### preserveMultipleSlashes
By default, multiple `/` characters (other than the leading `//`
in a UNC path, see "UNC Paths" above) are treated as a single
`/`.
That is, a pattern like `a///b` will match the file path `a/b`.
Set `preserveMultipleSlashes: true` to suppress this behavior.
### optimizationLevel
A number indicating the level of optimization that should be done
to the pattern prior to parsing and using it for matches.
Globstar parts `**` are always converted to `*` when `noglobstar`
is set, and multiple adjacent `**` parts are converted into a
single `**` (ie, `a/**/**/b` will be treated as `a/**/b`, as this
is equivalent in all cases).
- `0` - Make no further changes. In this mode, `.` and `..` are
maintained in the pattern, meaning that they must also appear
in the same position in the test path string. Eg, a pattern
like `a/*/../c` will match the string `a/b/../c` but not the
string `a/c`.
- `1` - (default) Remove cases where a double-dot `..` follows a
pattern portion that is not `**`, `.`, `..`, or empty `''`. For
example, the pattern `./a/b/../*` is converted to `./a/*`, and
so it will match the path string `./a/c`, but not the path
string `./a/b/../c`. Dots and empty path portions in the
pattern are preserved.
- `2` (or higher) - Much more aggressive optimizations, suitable
for use with file-walking cases:
- Remove cases where a double-dot `..` follows a pattern
portion that is not `**`, `.`, or empty `''`. Remove empty
and `.` portions of the pattern, where safe to do so (ie,
anywhere other than the last position, the first position, or
the second position in a pattern starting with `/`, as this
may indicate a UNC path on Windows).
- Convert patterns containing `<pre>/**/../<p>/<rest>` into the
equivalent `<pre>/{..,**}/<p>/<rest>`, where `<p>` is a
a pattern portion other than `.`, `..`, `**`, or empty
`''`.
- Dedupe patterns where a `**` portion is present in one and
omitted in another, and it is not the final path portion, and
they are otherwise equivalent. So `{a/**/b,a/b}` becomes
`a/**/b`, because `**` matches against an empty path portion.
- Dedupe patterns where a `*` portion is present in one, and a
non-dot pattern other than `**`, `.`, `..`, or `''` is in the
same position in the other. So `a/{*,x}/b` becomes `a/*/b`,
because `*` can match against `x`.
While these optimizations improve the performance of
file-walking use cases such as [glob](http://npm.im/glob) (ie,
the reason this module exists), there are cases where it will
fail to match a literal string that would have been matched in
optimization level 1 or 0.
Specifically, while the `Minimatch.match()` method will
optimize the file path string in the same ways, resulting in
the same matches, it will fail when tested with the regular
expression provided by `Minimatch.makeRe()`, unless the path
string is first processed with
`minimatch.levelTwoFileOptimize()` or similar.
### platform
When set to `win32`, this will trigger all windows-specific
behaviors (special handling for UNC paths, and treating `\` as
separators in file paths for comparison.)
Defaults to the value of `process.platform`.
### maxGlobstarRecursion
Max number of non-adjacent `**` patterns to recursively walk
down.
The default of `200` is almost certainly high enough for most
purposes, and can handle absurdly excessive patterns.
If the limit is exceeded (which would require very excessively
long patterns and paths containing lots of `**` patterns!), then
it is treated as non-matching, even if the path would normally
match the pattern provided.
That is, this is an intentional false negative, deemed an
acceptable break in correctness for security and performance.
### maxExtglobRecursion
Max depth to traverse for nested extglobs like `*(a|b|c)`
Default is 2, which is quite low, but any higher value swiftly
results in punishing performance impacts. Note that this is _not_
relevant when the globstar types can be safely coalesced into a
single set.
For example, `*(a|@(b|c)|d)` would be flattened into
`*(a|b|c|d)`. Thus, many common extglobs will retain good
performance and never hit this limit, even if they are
excessively deep and complicated.
If the limit is hit, then the extglob characters are simply not
parsed, and the pattern effectively switches into `noextglob:
true` mode for the contents of that nested sub-pattern. This will
typically _not_ result in a match, but is considered a valid
trade-off for security and performance.
## Comparisons to other fnmatch/glob implementations
While strict compliance with the existing standards is a
worthwhile goal, some discrepancies exist between minimatch and
other implementations. Some are intentional, and some are
unavoidable.
If the pattern starts with a `!` character, then it is negated. Set the
`nonegate` flag to suppress this behavior, and treat leading `!`
characters normally. This is perhaps relevant if you wish to start the
pattern with a negative extglob pattern like `!(a|B)`. Multiple `!`
characters at the start of a pattern will negate the pattern multiple
times.
If a pattern starts with `#`, then it is treated as a comment, and
will not match anything. Use `\#` to match a literal `#` at the
start of a line, or set the `nocomment` flag to suppress this behavior.
The double-star character `**` is supported by default, unless the
`noglobstar` flag is set. This is supported in the manner of bsdglob
and bash 4.1, where `**` only has special significance if it is the only
thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but
`a/**b` will not.
If an escaped pattern has no matches, and the `nonull` flag is set,
then minimatch.match returns the pattern as-provided, rather than
interpreting the character escapes. For example,
`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
`"*a?"`. This is akin to setting the `nullglob` option in bash, except
that it does not resolve escaped pattern characters.
If brace expansion is not disabled, then it is performed before any
other interpretation of the glob pattern. Thus, a pattern like
`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
checked for validity. Since those two are valid, matching proceeds.
Negated extglob patterns are handled as closely as possible to
Bash semantics, but there are some cases with negative extglobs
which are exceedingly difficult to express in a JavaScript
regular expression. In particular the negated pattern
`<start>!(<pattern>*|)*` will in bash match anything that does
not start with `<start><pattern>`. However,
`<start>!(<pattern>*)*` _will_ match paths starting with
`<start><pattern>`, because the empty string can match against
the negated portion. In this library, `<start>!(<pattern>*|)*`
will _not_ match any pattern starting with `<start>`, due to a
difference in precisely which patterns are considered "greedy" in
Regular Expressions vs bash path expansion. This may be fixable,
but not without incurring some complexity and performance costs,
and the trade-off seems to not be worth pursuing.
Note that `fnmatch(3)` in libc is an extremely naive string comparison
matcher, which does not do anything special for slashes. This library is
designed to be used in glob searching and file walkers, and so it does do
special things with `/`. Thus, `foo*` will not match `foo/bar` in this
library, even though it would in `fnmatch(3)`.

// for binding the start/end in either a joined full-path makeRe context
// (where we bind to (^|/), or a standalone matchPart context (where
// we bind to ^, and not /). Otherwise slashes get duped!
//
// In part-matching mode, the start is:
// - if not isStart: nothing
// - if traversal possible, but not allowed: ^(?!\.\.?$)
// - if dots allowed or not possible: ^
// - if dots possible and not allowed: ^(?!\.)
// end is:
// - if not isEnd(): nothing
// - else: $
//
// In full-path matching mode, we put the slash at the START of the
// pattern, so start is:
// - if first pattern: same as part-matching mode
// - if not isStart(): nothing
// - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
// - if dots allowed or not possible: /
// - if dots possible and not allowed: /(?!\.)
// end is:
// - if last pattern, same as part-matching mode
// - else nothing
//
// Always put the (?:$|/) on negated tails, though, because that has to be
// there to bind the end of the negated pattern portion, and it's easier to
// just stick it in now rather than try to inject it later in the middle of
// the pattern.
//
// We can just always return the same end, and leave it up to the caller
// to know whether it's going to be used joined or in parts.
// And, if the start is adjusted slightly, can do the same there:
// - if not isStart: nothing
// - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
// - if dots allowed or not possible: (?:/|^)
// - if dots possible and not allowed: (?:/|^)(?!\.)
//
// But it's better to have a simpler binding without a conditional, for
// performance, so probably better to return both start options.
//
// Then the caller just ignores the end if it's not the first pattern,
// and the start always gets applied.
//
// But that's always going to be $ if it's the ending pattern, or nothing,
// so the caller can just attach $ at the end of the pattern when building.
//
// So the todo is:
// - better detect what kind of start is needed
// - return both flavors of starting pattern
// - attach $ at the end of the pattern when creating the actual RegExp
//
// Ah, but wait, no, that all only applies to the root when the first pattern
// is not an extglob. If the first pattern IS an extglob, then we need all
// that dot prevention biz to live in the extglob portions, because eg
// +(*|.x*) can match .xy but not .yx.
//
// So, return the two flavors if it's #root and the first child is not an
// AST, otherwise leave it to the child AST to handle it, and there,
// use the (?:^|/) style of start binding.
//
// Even simplified further:
// - Since the start for a join is eg /(?!\.) and the start for a part
// is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
// or start or whatever) and prepend ^ or / at the Regexp construction.

// for binding the start/end in either a joined full-path makeRe context
// (where we bind to (^|/), or a standalone matchPart context (where
// we bind to ^, and not /). Otherwise slashes get duped!
//
// In part-matching mode, the start is:
// - if not isStart: nothing
// - if traversal possible, but not allowed: ^(?!\.\.?$)
// - if dots allowed or not possible: ^
// - if dots possible and not allowed: ^(?!\.)
// end is:
// - if not isEnd(): nothing
// - else: $
//
// In full-path matching mode, we put the slash at the START of the
// pattern, so start is:
// - if first pattern: same as part-matching mode
// - if not isStart(): nothing
// - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
// - if dots allowed or not possible: /
// - if dots possible and not allowed: /(?!\.)
// end is:
// - if last pattern, same as part-matching mode
// - else nothing
//
// Always put the (?:$|/) on negated tails, though, because that has to be
// there to bind the end of the negated pattern portion, and it's easier to
// just stick it in now rather than try to inject it later in the middle of
// the pattern.
//
// We can just always return the same end, and leave it up to the caller
// to know whether it's going to be used joined or in parts.
// And, if the start is adjusted slightly, can do the same there:
// - if not isStart: nothing
// - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
// - if dots allowed or not possible: (?:/|^)
// - if dots possible and not allowed: (?:/|^)(?!\.)
//
// But it's better to have a simpler binding without a conditional, for
// performance, so probably better to return both start options.
//
// Then the caller just ignores the end if it's not the first pattern,
// and the start always gets applied.
//
// But that's always going to be $ if it's the ending pattern, or nothing,
// so the caller can just attach $ at the end of the pattern when building.
//
// So the todo is:
// - better detect what kind of start is needed
// - return both flavors of starting pattern
// - attach $ at the end of the pattern when creating the actual RegExp
//
// Ah, but wait, no, that all only applies to the root when the first pattern
// is not an extglob. If the first pattern IS an extglob, then we need all
// that dot prevention biz to live in the extglob portions, because eg
// +(*|.x*) can match .xy but not .yx.
//
// So, return the two flavors if it's #root and the first child is not an
// AST, otherwise leave it to the child AST to handle it, and there,
// use the (?:^|/) style of start binding.
//
// Even simplified further:
// - Since the start for a join is eg /(?!\.) and the start for a part
// is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
// or start or whatever) and prepend ^ or / at the Regexp construction.

# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
> Detect whether a terminal supports color
## Install
```
$ npm install supports-color
```
## Usage
```js
const supportsColor = require('supports-color');
if (supportsColor.stdout) {
console.log('Terminal stdout supports color');
}
if (supportsColor.stdout.has256) {
console.log('Terminal stdout supports 256 colors');
}
if (supportsColor.stderr.has16m) {
console.log('Terminal stderr supports 16 million colors (truecolor)');
}
```
## API
Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
- `.level = 2` and `.has256 = true`: 256 color support
- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
## Info
It obeys the `--color` and `--no-color` CLI flags.
Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
