These plugins can extend the functionality of the library, adding other ways for files/contexts to be resolved. + +A plugin should be a `class` (or its ES5 equivalent) with an `apply` method. The `apply` method will receive a `resolver` instance, that can be used to hook in to the event system. + +### Plugin Boilerplate +```js +class MyResolverPlugin { + constructor(source, target) { + this.source = source; + this.target = target; + } + + apply(resolver) { + const target = resolver.ensureHook(this.target); + resolver.getHook(this.source).tapAsync("MyResolverPlugin", (request, resolveContext, callback) => { + // Any logic you need to create a new `request` can go here + resolver.doResolve(target, request, null, resolveContext, callback); + }); + } +} +``` + +Plugins are executed in a pipeline, and register which event they should be executed before/after. In the example above, `source` is the name of the event that starts the pipeline, and `target` is what event this plugin should fire, which is what continues the execution of the pipeline. For an example of how these different plugin events create a chain, see `lib/ResolverFactory.js`, in the `//// pipeline ////` section. + +## Tests + +``` javascript +npm test +``` + +[![Build Status](https://secure.travis-ci.org/webpack/enhanced-resolve.png?branch=master)](http://travis-ci.org/webpack/enhanced-resolve) + + +## Passing options from webpack +If you are using `webpack`, and you want to pass custom options to `enhanced-resolve`, the options are passed from the `resolve` key of your webpack configuration e.g.: + +``` +resolve: { + extensions: ['', '.js', '.jsx'], + modules: ['src', 'node_modules'], + plugins: [new DirectoryNamedWebpackPlugin()] + ... +}, +``` + +## License + +Copyright (c) 2012-2016 Tobias Koppers + +MIT (http://www.opensource.org/licenses/mit-license.php) -- cgit v1.2.3
