# CJS Module Lexer
[![Build Status][travis-image]][travis-url]
A [very fast](#benchmarks) JS CommonJS module syntax lexer used to detect the most likely list of named exports of a CommonJS module.
Outputs the list of named exports (`exports.name = ...`) and possible module reexports (`module.exports = require('...')`), including the common transpiler variations of these cases.
Forked from https://github.com/guybedford/es-module-lexer.
_Comprehensively handles the JS language grammar while remaining small and fast. - ~90ms per MB of JS cold and ~15ms per MB of JS warm, [see benchmarks](#benchmarks) for more info._
### Project Status
This project is used in Node.js core for detecting the named exports available when importing a CJS module into ESM, and is maintained for this purpose.
PRs will be accepted and upstreamed for parser bugs, performance improvements or new syntax support only.
_Detection patterns for this project are **frozen**_. This is because adding any new export detection patterns would result in fragmented backwards-compatibility. Specifically, it would be very difficult to figure out why an ES module named export for CommonJS might work in newer Node.js versions but not older versions. This problem would only be discovered downstream of module authors, with the fix for module authors being to then have to understand which patterns in this project provide full backwards-compatibily. Rather, by fully freezing the detected patterns, if it works in any Node.js version it will work in any other. Build tools can also reliably treat the supported syntax for this project as a part of their output target for ensuring syntax support.
### Usage
```
npm install cjs-module-lexer
```
For use in CommonJS:
```js
const { parse } = require('cjs-module-lexer');
// `init` return a promise for parity with the ESM API, but you do not have to call it
const { exports, reexports } = parse(`
// named exports detection
module.exports.a = 'a';
(function () {
exports.b = 'b';
})();
Object.defineProperty(exports, 'c', { value: 'c' });
/* exports.d = 'not detected'; */
// reexports detection
if (maybe) module.exports = require('./dep1.js');
if (another) module.exports = require('./dep2.js');
// literal exports assignments
module.exports = { a, b: c, d, 'e': f }
// __esModule detection
Object.defineProperty(module.exports, '__esModule', { value: true })
`);
// exports === ['a', 'b', 'c', '__esModule']
// reexports === ['./dep1.js', './dep2.js']
```
When using the ESM version, Wasm is supported instead:
```js
import { parse, init } from 'cjs-module-lexer';
// init() needs to be called and waited upon, or use initSync() to compile
// Wasm blockingly and synchronously.
await init();
const { exports, reexports } = parse(source);
```
The Wasm build is around 1.5x faster and without a cold start.
### Grammar
CommonJS exports matches are run against the source token stream.
The token grammar is:
```
IDENTIFIER: As defined by ECMA-262, without support for identifier `\` escapes, filtered to remove strict reserved words:
"implements", "interface", "let", "package", "private", "protected", "public", "static", "yield", "enum"
STRING_LITERAL: A `"` or `'` bounded ECMA-262 string literal.
MODULE_EXPORTS: `module` `.` `exports`
EXPORTS_IDENTIFIER: MODULE_EXPORTS_IDENTIFIER | `exports`
EXPORTS_DOT_ASSIGN: EXPORTS_IDENTIFIER `.` IDENTIFIER `=`
EXPORTS_LITERAL_COMPUTED_ASSIGN: EXPORTS_IDENTIFIER `[` STRING_LITERAL `]` `=`
EXPORTS_LITERAL_PROP: (IDENTIFIER (`:` IDENTIFIER)?) | (STRING_LITERAL `:` IDENTIFIER)
EXPORTS_SPREAD: `...` (IDENTIFIER | REQUIRE)
EXPORTS_MEMBER: EXPORTS_DOT_ASSIGN | EXPORTS_LITERAL_COMPUTED_ASSIGN
EXPORTS_DEFINE: `Object` `.` `defineProperty `(` EXPORTS_IDENFITIER `,` STRING_LITERAL
EXPORTS_DEFINE_VALUE: EXPORTS_DEFINE `, {`
(`enumerable: true,`)?
(
`value:` |
`get` (`: function` IDENTIFIER? )? `() {` return IDENTIFIER (`.` IDENTIFIER | `[` STRING_LITERAL `]`)? `;`? `}` `,`?
)
`})`
EXPORTS_LITERAL: MODULE_EXPORTS `=` `{` (EXPORTS_LITERAL_PROP | EXPORTS_SPREAD) `,`)+ `}`
REQUIRE: `require` `(` STRING_LITERAL `)`
EXPORTS_ASSIGN: (`var` | `const` | `let`) IDENTIFIER `=` (`_interopRequireWildcard (`)? REQUIRE
MODULE_EXPORTS_ASSIGN: MODULE_EXPORTS `=` REQUIRE
EXPORT_STAR: (`__export` | `__exportStar`) `(` REQUIRE
EXPORT_STAR_LIB: `Object.keys(` IDENTIFIER$1 `).forEach(function (` IDENTIFIER$2 `) {`
(
(
`if (` IDENTIFIER$2 `===` ( `'default'` | `"default"` ) `||` IDENTIFIER$2 `===` ( '__esModule' | `"__esModule"` ) `) return` `;`?
(
(`if (Object` `.prototype`? `.hasOwnProperty.call(` IDENTIFIER `, ` IDENTIFIER$2 `)) return` `;`?)?
(`if (` IDENTIFIER$2 `in` EXPORTS_IDENTIFIER `&&` EXPORTS_IDENTIFIER `[` IDENTIFIER$2 `] ===` IDENTIFIER$1 `[` IDENTIFIER$2 `]) return` `;`)?
)?
) |
`if (` IDENTIFIER$2 `!==` ( `'default'` | `"default"` ) (`&& !` (`Object` `.prototype`? `.hasOwnProperty.call(` IDENTIFIER `, ` IDENTIFIER$2 `)` | IDENTIFIER `.hasOwnProperty(` IDENTIFIER$2 `)`))? `)`
)
(
EXPORTS_IDENTIFIER `[` IDENTIFIER$2 `] =` IDENTIFIER$1 `[` IDENTIFIER$2 `]` `;`? |
`Object.defineProperty(` EXPORTS_IDENTIFIER `, ` IDENTIFIER$2 `, { enumerable: true, get` (`: function` IDENTIFIER? )? `() { return ` IDENTIFIER$1 `[` IDENTIFIER$2 `]` `;`? `}` `,`? `})` `;`?
)
`})`
```
Spacing between tokens is taken to be any ECMA-262 whitespace, ECMA-262 block comment or ECMA-262 line comment.
* The returned export names are taken to be the combination of:
1. All `IDENTIFIER` and `STRING_LITERAL` slots for `EXPORTS_MEMBER` and `EXPORTS_LITERAL` matches.
2. The first `STRING_LITERAL` slot for all `EXPORTS_DEFINE_VALUE` matches where that same string is not an `EXPORTS_DEFINE` match that is not also an `EXPORTS_DEFINE_VALUE` match.
* The reexport specifiers are taken to be the combination of:
1. The `REQUIRE` matches of the last matched of either `MODULE_EXPORTS_ASSIGN` or `EXPORTS_LITERAL`.
2. All _top-level_ `EXPORT_STAR` `REQUIRE` matches and `EXPORTS_ASSIGN` matches whose `IDENTIFIER` also matches the first `IDENTIFIER` in `EXPORT_STAR_LIB`.
### Parsing Examples
#### Named Exports Parsing
The basic matching rules for named exports are `exports.name`, `exports['name']` or `Object.defineProperty(exports, 'name', ...)`. This matching is done without scope analysis and regardless of the expression position:
```js
// DETECTS EXPORTS: a, b
(function (exports) {
exports.a = 'a';
exports['b'] = 'b';
})(exports);
```
Because there is no scope analysis, the above detection may overclassify:
```js
// DETECTS EXPORTS: a, b, c
(function (exports, Object) {
exports.a = 'a';
exports['b'] = 'b';
if (false)
exports.c = 'c';
})(NOT_EXPORTS, NOT_OBJECT);
```
It will in turn underclassify in cases where the identifiers are renamed:
```js
// DETECTS: NO EXPORTS
(function (e) {
e.a = 'a';
e['b'] = 'b';
})(exports);
```
#### Getter Exports Parsing
`Object.defineProperty` is detected for specifically value and getter forms returning an identifier or member expression:
```js
// DETECTS: a, b, c, d, __esModule
Object.defineProperty(exports, 'a', {
enumerable: true,
get: function () {
return q.p;
}
});
Object.defineProperty(exports, 'b', {
enumerable: true,
get: function () {
return q['p'];
}
});
Object.defineProperty(exports, 'c', {
enumerable: true,
get () {
return b;
}
});
Object.defineProperty(exports, 'd', { value: 'd' });
Object.defineProperty(exports, '__esModule', { value: true });
```
Value properties are also detected specifically:
```js
Object.defineProperty(exports, 'a', {
value: 'no problem'
});
```
To avoid matching getters that have side effects, any getter for an export name that does not support the forms above will
opt-out of the getter matching:
```js
// DETECTS: NO EXPORTS
Object.defineProperty(exports, 'a', {
get () {
return 'nope';
}
});
if (false) {
Object.defineProperty(module.exports, 'a', {
get () {
return dynamic();
}
})
}
```
Alternative object definition structures or getter function bodies are not detected:
```js
// DETECTS: NO EXPORTS
Object.defineProperty(exports, 'a', {
enumerable: false,
get () {
return p;
}
});
Object.defineProperty(exports, 'b', {
configurable: true,
get () {
return p;
}
});
Object.defineProperty(exports, 'c', {
get: () => p
});
Object.defineProperty(exports, 'd', {
enumerable: true,
get: function () {
return dynamic();
}
});
Object.defineProperty(exports, 'e', {
enumerable: true,
get () {
return 'str';
}
});
```
`Object.defineProperties` is also not supported.
#### Exports Object Assignment
A best-effort is made to detect `module.exports` object assignments, but because this is not a full parser, arbitrary expressions are not handled in the
object parsing process.
Simple object definitions are supported:
```js
// DETECTS EXPORTS: a, b, c
module.exports = {
a,
'b': b,
c: c,
...d
};
```
Object properties that are not identifiers or string expressions will bail out of the object detection, while spreads are ignored:
```js
// DETECTS EXPORTS: a, b
module.exports = {
a,
...d,
b: require('c'),
c: "not detected since require('c') above bails the object detection"
}
```
`Object.defineProperties` is not currently supported either.
#### module.exports reexport assignment
Any `module.exports = require('mod')` assignment is detected as a reexport, but only the last one is returned:
```js
// DETECTS REEXPORTS: c
module.exports = require('a');
(module => module.exports = require('b'))(NOT_MODULE);
if (false) module.exports = require('c');
```
This is to avoid over-classification in Webpack bundles with externals which include `module.exports = require('external')` in their source for every external dependency.
In exports object assignment, any spread of `require()` are detected as multiple separate reexports:
```js
// DETECTS REEXPORTS: a, b
module.exports = require('ignored');
module.exports = {
...require('a'),
...require('b')
};
```
#### Transpiler Re-exports
For named exports, transpiler output works well with the rules described above.
But for star re-exports, special care is taken to support common patterns of transpiler outputs from Babel and TypeScript as well as bundlers like RollupJS.
These reexport and star reexport patterns are restricted to only be detected at the top-level as provided by the direct output of these tools.
For example, `export * from 'external'` is output by Babel as:
```js
"use strict";
exports.__esModule = true;
var _external = require("external");
Object.keys(_external).forEach(function (key) {
if (key === "default" || key === "__esModule") return;
exports[key] = _external[key];
});
```
Where the `var _external = require("external")` is specifically detected as well as the `Object.keys(_external)` statement, down to the exact
for of that entire expression including minor variations of the output. The `_external` and `key` identifiers are carefully matched in this
detection.
Similarly for TypeScript, `export * from 'external'` is output as:
```js
"use strict";
function __export(m) {
for (var p in m) if (!exports.hasOwnProperty(p)) exports[p] = m[p];
}
Object.defineProperty(exports, "__esModule", { value: true });
__export(require("external"));
```
Where the `__export(require("external"))` statement is explicitly detected as a reexport, including variations `tslib.__export` and `__exportStar`.
### Environment Support
Node.js 10+, and [all browsers with Web Assembly support](https://caniuse.com/#feat=wasm).
### JS Grammar Support
* Token state parses all line comments, block comments, strings, template strings, blocks, parens and punctuators.
* Division operator / regex token ambiguity is handled via backtracking checks against punctuator prefixes, including closing brace or paren backtracking.
* Always correctly parses valid JS source, but may parse invalid JS source without errors.

### Wasm Build Steps
To build download the WASI SDK from https://github.com/WebAssembly/wasi-sdk/releases.
The Makefile assumes the existence of "wasi-sdk-11.0" and "wabt" (optional) as sibling folders to this project.
The build through the Makefile is then run via `make lib/lexer.wasm`, which can also be triggered via `npm run build-wasm` to create `dist/lexer.js`.
On Windows it may be preferable to use the Linux subsystem.
After the Web Assembly build, the CJS build can be triggered via `npm run build`.
Optimization passes are run with [Binaryen](https://github.com/WebAssembly/binaryen) prior to publish to reduce the Web Assembly footprint.
