# @rollup/plugin-node-resolve
🍣 A Rollup plugin which locates modules using the [Node resolution algorithm](https://nodejs.org/api/modules.html#modules_all_together), for using third party modules in `node_modules`
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v14.0.0+) and Rollup v2.78.0+.
## Install
Using npm:
```console
npm install @rollup/plugin-node-resolve --save-dev
```
## Usage
Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
```js
import { nodeResolve } from '@rollup/plugin-node-resolve';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [nodeResolve()]
};
```
Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
## Package entrypoints
This plugin supports the package entrypoints feature from node js, specified in the `exports` or `imports` field of a package. Check the [official documentation](https://nodejs.org/api/packages.html#packages_package_entry_points) for more information on how this works. This is the default behavior. In the abscence of these fields, the fields in `mainFields` will be the ones to be used.
## Options
### `exportConditions`
Type: `Array[...String]`<br>
Default: `[]`
Additional conditions of the package.json exports field to match when resolving modules. By default, this plugin looks for the `['default', 'module', 'import']` conditions when resolving imports.
When using `@rollup/plugin-commonjs` v16 or higher, this plugin will use the `['default', 'module', 'require']` conditions when resolving require statements.
Setting this option will add extra conditions on top of the default conditions. See https://nodejs.org/api/packages.html#packages_conditional_exports for more information.
In order to get the [resolution behavior of Node.js](https://nodejs.org/api/packages.html#packages_conditional_exports), set this to `['node']`.
### `browser`
Type: `Boolean`<br>
Default: `false`
If `true`, instructs the plugin to use the browser module resolutions in `package.json` and adds `'browser'` to `exportConditions` if it is not present so browser conditionals in `exports` are applied. If `false`, any browser properties in package files will be ignored. Alternatively, a value of `'browser'` can be added to both the `mainFields` and `exportConditions` options, however this option takes precedence over `mainFields`.
> This option does not work when a package is using [package entrypoints](https://nodejs.org/api/packages.html#packages_package_entry_points)
### `moduleDirectories`
Type: `Array[...String]`<br>
Default: `['node_modules']`
A list of directory names in which to recursively look for modules.
### `modulePaths`
Type: `Array[...String]`<br>
Default: `[]`
A list of absolute paths to additional locations to search for modules. [This is analogous to setting the `NODE_PATH` environment variable for node](https://nodejs.org/api/modules.html#loading-from-the-global-folders).
### `dedupe`
Type: `Array[...String]`<br>
Default: `[]`
An `Array` of modules names, which instructs the plugin to force resolving for the specified modules to the root `node_modules`. Helps to prevent bundling the same package multiple times if package is imported from dependencies.
```js
dedupe: ['my-package', '@namespace/my-package'];
```
This will deduplicate bare imports such as:
```js
import 'my-package';
import '@namespace/my-package';
```
And it will deduplicate deep imports such as:
```js
import 'my-package/foo.js';
import '@namespace/my-package/bar.js';
```
### `extensions`
Type: `Array[...String]`<br>
Default: `['.mjs', '.js', '.json', '.node']`
Specifies the extensions of files that the plugin will operate on.
### `jail`
Type: `String`<br>
Default: `'/'`
Locks the module search within specified path (e.g. chroot). Modules defined outside this path will be ignored by this plugin.
### `mainFields`
Type: `Array[...String]`<br>
Default: `['module', 'main']`<br>
Valid values: `['browser', 'jsnext:main', 'module', 'main']`
Specifies the properties to scan within a `package.json`, used to determine the bundle entry point. The order of property names is significant, as the first-found property is used as the resolved entry point. If the array contains `'browser'`, key/values specified in the `package.json` `browser` property will be used.
### `preferBuiltins`
Type: `Boolean | (module: string) => boolean`<br>
Default: `true` (with warnings if a builtin module is used over a local version. Set to `true` to disable warning.)
If `true`, the plugin will prefer built-in modules (e.g. `fs`, `path`). If `false`, the plugin will look for locally installed modules of the same name.
Alternatively, you may pass in a function that returns a boolean to confirm whether the plugin should prefer built-in modules. e.g.
```js
preferBuiltins: (module) => module !== 'punycode';
```
will not treat `punycode` as a built-in module
### `modulesOnly`
Type: `Boolean`<br>
Default: `false`
If `true`, inspect resolved files to assert that they are ES2015 modules.
### `resolveOnly`
Type: `Array[...String|RegExp] | (module: string) => boolean`<br>
Default: `null`
An `Array` which instructs the plugin to limit module resolution to those whose names match patterns in the array. _Note: Modules not matching any patterns will be marked as external._
Alternatively, you may pass in a function that returns a boolean to confirm whether the module should be included or not.
Examples:
- `resolveOnly: ['batman', /^@batcave\/.*$/]`
- `resolveOnly: module => !module.includes('joker')`
### `rootDir`
Type: `String`<br>
Default: `process.cwd()`
Specifies the root directory from which to resolve modules. Typically used when resolving entry-point imports, and when resolving deduplicated modules. Useful when executing rollup in a package of a mono-repository.
```
// Set the root directory to be the parent folder
rootDir: path.join(process.cwd(), '..')
```
### `ignoreSideEffectsForRoot`
If you use the `sideEffects` property in the package.json, by default this is respected for files in the root package. Set to `true` to ignore the `sideEffects` configuration for the root package.
### `allowExportsFolderMapping`
Older Node versions supported exports mappings of folders like
```json
{
"exports": {
"./foo/": "./dist/foo/"
}
}
```
This was deprecated with Node 14 and removed in Node 17, instead it is recommended to use exports patterns like
```json
{
"exports": {
"./foo/*": "./dist/foo/*"
}
}
```
But for backwards compatibility this behavior is still supported by enabling the `allowExportsFolderMapping` (defaults to `true`).
The default value might change in a futur major release.
## Preserving symlinks
This plugin honours the rollup [`preserveSymlinks`](https://rollupjs.org/guide/en/#preservesymlinks) option.
## Using with @rollup/plugin-commonjs
Since most packages in your node_modules folder are probably legacy CommonJS rather than JavaScript modules, you may need to use [@rollup/plugin-commonjs](https://github.com/rollup/plugins/tree/master/packages/commonjs):
```js
// rollup.config.js
import { nodeResolve } from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
export default {
input: 'main.js',
output: {
file: 'bundle.js',
format: 'iife',
name: 'MyModule'
},
plugins: [nodeResolve(), commonjs()]
};
```
## Resolving Built-Ins (like `fs`)
By default this plugin will prefer built-ins over local modules, marking them as external.
See [`preferBuiltins`](#preferbuiltins).
To provide stubbed versions of Node built-ins, use a plugin like [rollup-plugin-node-polyfills](https://github.com/ionic-team/rollup-plugin-node-polyfills) and set `preferBuiltins` to `false`. e.g.
```js
import { nodeResolve } from '@rollup/plugin-node-resolve';
import nodePolyfills from 'rollup-plugin-node-polyfills';
export default ({
input: ...,
plugins: [
nodePolyfills(),
nodeResolve({ preferBuiltins: false })
],
external: builtins,
output: ...
})
```
## Resolving Require Statements
According to [NodeJS module resolution](https://nodejs.org/api/packages.html#packages_package_entry_points) `require` statements should resolve using the `require` condition in the package exports field, while es modules should use the `import` condition.
The node resolve plugin uses `import` by default, you can opt into using the `require` semantics by passing an extra option to the resolve function:
```js
this.resolve(importee, importer, {
skipSelf: true,
custom: { 'node-resolve': { isRequire: true } }
});
```
## Resolve Options
After this plugin resolved an import id to its target file in `node_modules`, it will invoke `this.resolve` again with the resolved id. It will pass the following information in the resolve options:
```js
this.resolve(resolved.id, importer, {
custom: {
'node-resolve': {
resolved, // the object with information from node.js resolve
importee // the original import id
}
}
});
```
Your plugin can use the `importee` information to map an original import to its resolved file in `node_modules`, in a plugin hook such as `resolveId`.
The `resolved` object contains the resolved id, which is passed as the first parameter. It also has a property `moduleSideEffects`, which may contain the value from the npm `package.json` field `sideEffects` or `null`.

# @rollup/plugin-terser
🍣 A Rollup plugin to generate a minified bundle with terser.
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v14.0.0+) and Rollup v2.0+.
## Install
Using npm:
```console
npm install @rollup/plugin-terser --save-dev
```
## Usage
Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
```typescript
import terser from '@rollup/plugin-terser';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [terser()]
};
```
Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
## Options
The plugin accepts a terser [Options](https://github.com/terser/terser#minify-options) object as input parameter,
to modify the default behaviour.
In addition to the `terser` options, it is also possible to provide the following options:
### `maxWorkers`
Type: `Number`<br>
Default: `undefined`
Instructs the plugin to use a specific amount of cpu threads.
```typescript
import terser from '@rollup/plugin-terser';
export default {
input: 'src/index.js',
output: {
dir: 'output',
format: 'cjs'
},
plugins: [
terser({
maxWorkers: 4
})
]
};

# @rollup/pluginutils
A set of utility functions commonly used by 🍣 Rollup plugins.
## Requirements
The plugin utils require an [LTS](https://github.com/nodejs/Release) Node version (v14.0.0+) and Rollup v1.20.0+.
## Install
Using npm:
```console
npm install @rollup/pluginutils --save-dev
```
## Usage
```js
import utils from '@rollup/pluginutils';
//...
```
## API
Available utility functions are listed below:
_Note: Parameter names immediately followed by a `?` indicate that the parameter is optional._
### addExtension
Adds an extension to a module ID if one does not exist.
Parameters: `(filename: String, ext?: String)`<br>
Returns: `String`
```js
import { addExtension } from '@rollup/pluginutils';
export default function myPlugin(options = {}) {
return {
resolveId(code, id) {
// only adds an extension if there isn't one already
id = addExtension(id); // `foo` -> `foo.js`, `foo.js` -> `foo.js`
id = addExtension(id, '.myext'); // `foo` -> `foo.myext`, `foo.js` -> `foo.js`
}
};
}
```
### attachScopes
Attaches `Scope` objects to the relevant nodes of an AST. Each `Scope` object has a `scope.contains(name)` method that returns `true` if a given name is defined in the current scope or a parent scope.
Parameters: `(ast: Node, propertyName?: String)`<br>
Returns: `Object`
See [@rollup/plugin-inject](https://github.com/rollup/plugins/tree/master/packages/inject) or [@rollup/plugin-commonjs](https://github.com/rollup/plugins/tree/master/packages/commonjs) for an example of usage.
```js
import { attachScopes } from '@rollup/pluginutils';
import { walk } from 'estree-walker';
export default function myPlugin(options = {}) {
return {
transform(code) {
const ast = this.parse(code);
let scope = attachScopes(ast, 'scope');
walk(ast, {
enter(node) {
if (node.scope) scope = node.scope;
if (!scope.contains('foo')) {
// `foo` is not defined, so if we encounter it,
// we assume it's a global
}
},
leave(node) {
if (node.scope) scope = scope.parent;
}
});
}
};
}
```
### createFilter
Constructs a filter function which can be used to determine whether or not certain modules should be operated upon.
Parameters: `(include?: <picomatch>, exclude?: <picomatch>, options?: Object)`<br>
Returns: `(id: string | unknown) => boolean`
#### `include` and `exclude`
Type: `String | RegExp | Array[...String|RegExp]`<br>
A valid [`picomatch`](https://github.com/micromatch/picomatch#globbing-features) pattern, or array of patterns. If `options.include` is omitted or has zero length, filter will return `true` by default. Otherwise, an ID must match one or more of the `picomatch` patterns, and must not match any of the `options.exclude` patterns.
Note that `picomatch` patterns are very similar to [`minimatch`](https://github.com/isaacs/minimatch#readme) patterns, and in most use cases, they are interchangeable. If you have more specific pattern matching needs, you can view [this comparison table](https://github.com/micromatch/picomatch#library-comparisons) to learn more about where the libraries differ.
#### `options`
##### `resolve`
Type: `String | Boolean | null`
Optionally resolves the patterns against a directory other than `process.cwd()`. If a `String` is specified, then the value will be used as the base directory. Relative paths will be resolved against `process.cwd()` first. If `false`, then the patterns will not be resolved against any directory. This can be useful if you want to create a filter for virtual module names.
#### Usage
```js
import { createFilter } from '@rollup/pluginutils';
export default function myPlugin(options = {}) {
// assume that the myPlugin accepts options of `options.include` and `options.exclude`
var filter = createFilter(options.include, options.exclude, {
resolve: '/my/base/dir'
});
return {
transform(code, id) {
if (!filter(id)) return;
// proceed with the transformation...
}
};
}
```
### dataToEsm
Transforms objects into tree-shakable ES Module imports.
Parameters: `(data: Object, options: DataToEsmOptions)`<br>
Returns: `String`
#### `data`
Type: `Object`
An object to transform into an ES module.
#### `options`
Type: `DataToEsmOptions`
_Note: Please see the TypeScript definition for complete documentation of these options_
#### Usage
```js
import { dataToEsm } from '@rollup/pluginutils';
const esModuleSource = dataToEsm(
{
custom: 'data',
to: ['treeshake']
},
{
compact: false,
indent: '\t',
preferConst: true,
objectShorthand: true,
namedExports: true,
includeArbitraryNames: false
}
);
/*
Outputs the string ES module source:
export const custom = 'data';
export const to = ['treeshake'];
export default { custom, to };
*/
```
### extractAssignedNames
Extracts the names of all assignment targets based upon specified patterns.
Parameters: `(param: Node)`<br>
Returns: `Array[...String]`
#### `param`
Type: `Node`
An `acorn` AST Node.
#### Usage
```js
import { extractAssignedNames } from '@rollup/pluginutils';
import { walk } from 'estree-walker';
export default function myPlugin(options = {}) {
return {
transform(code) {
const ast = this.parse(code);
walk(ast, {
enter(node) {
if (node.type === 'VariableDeclarator') {
const declaredNames = extractAssignedNames(node.id);
// do something with the declared names
// e.g. for `const {x, y: z} = ...` => declaredNames = ['x', 'z']
}
}
});
}
};
}
```
### exactRegex
Constructs a RegExp that matches the exact string specified. This is useful for plugin hook filters.
Parameters: `(str: String | Array[...String], flags?: String)`<br>
Returns: `RegExp`
#### Usage
```js
import { exactRegex } from '@rollup/pluginutils';
exactRegex('foobar'); // /^foobar$/
exactRegex(['foo', 'bar']); // /^(?:foo|bar)$/
exactRegex('foo(bar)', 'i'); // /^foo\(bar\)$/i
```
### makeLegalIdentifier
Constructs a bundle-safe identifier from a `String`.
Parameters: `(str: String)`<br>
Returns: `String`
#### Usage
```js
import { makeLegalIdentifier } from '@rollup/pluginutils';
makeLegalIdentifier('foo-bar'); // 'foo_bar'
makeLegalIdentifier('typeof'); // '_typeof'
```
### normalizePath
Converts path separators to forward slash.
Parameters: `(filename: String)`<br>
Returns: `String`
#### Usage
```js
import { normalizePath } from '@rollup/pluginutils';
normalizePath('foo\\bar'); // 'foo/bar'
normalizePath('foo/bar'); // 'foo/bar'
```
### prefixRegex
Constructs a RegExp that matches a value that has the specified prefix. This is useful for plugin hook filters.
Parameters: `(str: String | Array[...String], flags?: String)`<br>
Returns: `RegExp`
#### Usage
```js
import { prefixRegex } from '@rollup/pluginutils';
prefixRegex('foobar'); // /^foobar/
prefixRegex(['foo', 'bar']); // /^(?:foo|bar)/
prefixRegex('foo(bar)', 'i'); // /^foo\(bar\)/i
```
### suffixRegex
Constructs a RegExp that matches a value that has the specified suffix. This is useful for plugin hook filters.
Parameters: `(str: String | Array[...String], flags?: String)`<br>
Returns: `RegExp`
#### Usage
```js
import { suffixRegex } from '@rollup/pluginutils';
suffixRegex('foobar'); // /foobar$/
suffixRegex(['foo', 'bar']); // /(?:foo|bar)$/
suffixRegex('foo(bar)', 'i'); // /foo\(bar\)$/i
