[![tests][tests]][tests-url] [![cover][cover]][cover-url] [![size][size]][size-url] [![libera manifesto](https://img.shields.io/badge/libera-manifesto-lightgrey.svg)](https://liberamanifesto.com) # webpack-manifest-plugin A Webpack plugin for generating an asset manifest. :heart: Please consider [Sponsoring my work](https://github.com/sponsors/shellscape) ## Requirements `webpack-manifest-plugin` is an [evergreen 🌲](./.github/FAQ.md#what-does-evergreen-mean) module. This module requires an [Active LTS](https://github.com/nodejs/Release) Node version (v10.0.0+) and Webpack v4.44.0+. ## Contributing This repository leverages [pnpm](https://pnpm.js.org/) for dependency management. To begin, please install `pnpm`: ```console $ npm install pnpm -g ``` ## Install Using npm: ```console npm install webpack-nano webpack-manifest-plugin --save-dev ``` _Note: We recommend using [webpack-nano](https://github.com/shellscape/webpack-nano), a very tiny, very clean webpack CLI._ ## Usage Create a `webpack.config.js` file: ```js const { WebpackManifestPlugin } = require('webpack-manifest-plugin'); const options = { ... }; module.exports = { // an example entry definition entry: [ 'app.js' ], ... plugins: [ new WebpackManifestPlugin(options) ] }; ``` And run `webpack`: ```console $ npx wp ``` With the default options, the example above will create a `manifest.json` file in the output directory for the build. The manifest file will contain a map of source filenames to the corresponding build output file. e.g. ```json { "dist/batman.js": "dist/batman.1234567890.js", "dist/joker.js": "dist/joker.0987654321.js" } ``` ### Options ### `basePath` Type: `String`
Default: `''` Specifies a path prefix for all keys in the manifest. Useful for including your output path in the manifest. ### `fileName` Type: `String`
Default: `manifest.json` Specifies the file name to use for the resulting manifest. By default the plugin will emit `manifest.json` to your output directory. Passing an absolute path to the `fileName` option will override both the file name and path. ### `filter` Type: `Function`
Default: `undefined` Allows filtering the files which make up the manifest. The passed function should match the signature of `(file: FileDescriptor) => Boolean`. Return `true` to keep the file, `false` to remove the file. ### `generate` Type: `Function`
Default: `undefined` A custom `Function` to create the manifest. The passed function should match the signature of `(seed: Object, files: FileDescriptor[], entries: string[]) => Object` and can return anything as long as it's serialisable by `JSON.stringify`. ### `map` Type: `Function`
Default: `undefined` Allows modifying the files which make up the manifest. The passed function should match the signature of `(file: FileDescriptor) => FileDescriptor` where an object matching `FileDescriptor` is returned. ### `publicPath` Type: `String`
Default: `.output.publicPath` A path prefix that will be added to values of the manifest. ### `removeKeyHash` Type: `RegExp | false`
Default: `/([a-f0-9]{32}\.?)/gi` If set to a valid `RegExp`, removes hashes from manifest keys. e.g. ```json { "index.c5a9bff71fdfed9b6046.html": "index.c5a9bff71fdfed9b6046.html" } ``` ```json { "index.html": "index.c5a9bff71fdfed9b6046.html" } ``` The default value for this option is a regular expression targeting Webpack's [default md5 hash](https://webpack.js.org/configuration/output/#outputhashfunction). To target other hashing functions / algorithms, set this option to an appropriate `RegExp`. To disable replacing the hashes in key names, set this option to `false`. ### `seed` Type: `Object`
Default: `{}` A cache of key/value pairs used to seed the manifest. This may include a set of [custom key/value](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/manifest.json) pairs to include in your manifest, or may be used to combine manifests across compilations in [multi-compiler mode](https://github.com/webpack/webpack/tree/master/examples/multi-compiler). To combine manifests, pass a shared seed object to each compiler's `WebpackManifestPlugin` instance. ### `serialize` Type: `Function(Object) => string`
Default: `undefined` A `Function` which can be leveraged to serialize the manifest in a different format than json. e.g. `yaml`. ### `sort` Type: `Function`
Default: `undefined` Allows sorting the files which make up the manifest. The passed function should match the signature of `(fileA: FileDescriptor, fileB: FileDescriptor) => Number`. Return `0` to indicate no change, `-1` to indicate the file should be moved to a lower index, and `1` to indicate the file shoud be moved to a higher index. ### `useEntryKeys` Type: `Boolean`
Default: `false` If `true`, the keys specified in the `entry` property will be used as keys in the manifest. No file extension will be added (unless specified as part of an `entry` property key). ### `useLegacyEmit` Type: `Boolean`
Default: `false` If `true`, the manifest will be written on the deprecated webpack `emit` hook to be compatible with not yet updated webpack plugins. A lot of webpack plugins are not yet updated to match the new webpack 5 API. This is a problem when other plugins use the deprecated `emit` hook. The manifest will be written before these other plugins and thus files are missing on the manifest. ### `writeToFileEmit` Type: `Boolean`
Default: `false` If `true`, will emit the manifest to the build directory _and_ in memory for compatibility with `webpack-dev-server`. ## Manifest File Descriptor This plugin utilizes the following object structure to work with files. Many options for this plugin utilize the structure below. ```ts { chunk?: Chunk; isAsset: boolean; isChunk: boolean; isInitial: boolean; isModuleAsset: boolean; name: string | null; path: string; } ``` ### `chunk` Type: [`Chunk`](https://github.com/webpack/webpack/blob/master/lib/Chunk.js) Only available if `isChunk` is `true` ### `isInitial` Type: `Boolean` Is required to run you app. Cannot be `true` if `isChunk` is `false`. ### `isModuleAsset` Type: `Boolean` Is required by a module. Cannot be `true` if `isAsset` is `false`. ## Compiler Hooks This plugin supports the following hooks via the `getCompilerHooks` export; `afterEmit`, `beforeEmit`. These hooks can be useful, e.g. changing manifest contents before emitting to disk. ### `getCompilerHooks` Returns: `{ afterEmit: SyncWaterfallHook, beforeEmit: SyncWaterfallHook }` ### `assetHookStage` Type: `Number` Default: `Infinity` If you need to consume the output of this plugin in another plugin, it can be useful to adjust the stage at which the manifest is generated. Pass a new stage to `assetHookStage` to change when the manifest is generated. See the [docs on `processAssets`](https://webpack.js.org/api/compilation-hooks/#list-of-asset-processing-stages) for more detail. Note: any files added to the compilation after the stage specified will not be included in the manifest. #### Usage ```js const { getCompilerHooks } = require('webpack-manifest-plugin'); class BatmanPlugin { apply(compiler) { const { beforeEmit } = getCompilerHooks(compiler); beforeEmit.tap('BatmanPlugin', (manifest) => { return { ...manifest, name: 'hello' }; }); } } ``` ## Notes - If using this plugin with `webpack-clean` and `webpack-dev-server`, please review [this issue](https://github.com/shellscape/webpack-manifest-plugin/issues/267). ## Attiribution Special thanks to [Dane Thurber](https://github.com/danethurber), the original author of this plugin, without whom this plugin would not exist. ## Meta [CONTRIBUTING](./.github/CONTRIBUTING.md) [LICENSE (MIT)](./LICENSE)
