+# enhanced-resolve
+
+Offers an async require.resolve function. It's highly configurable.
+
+## Features
+
+* plugin system
+* provide a custom filesystem
+* sync and async node.js filesystems included
+
+
+## Getting Started
+### Install
+```sh
+# npm
+npm install enhanced-resolve
+# or Yarn
+yarn add enhanced-resolve
+```
+
+### Creating a Resolver
+The easiest way to create a resolver is to use the `createResolver` function on `ResolveFactory`, along with one of the supplied File System implementations.
+```js
+const {
+  NodeJsInputFileSystem,
+  CachedInputFileSystem,
+  ResolverFactory
+} = require('enhanced-resolve');
+
+// create a resolver
+const myResolver = ResolverFactory.createResolver({
+  // Typical usage will consume the `NodeJsInputFileSystem` + `CachedInputFileSystem`, which wraps the Node.js `fs` wrapper to add resilience + caching.
+  fileSystem: new CachedInputFileSystem(new NodeJsInputFileSystem(), 4000),
+  extensions: ['.js', '.json']
+  /* any other resolver options here. Options/defaults can be seen below */
+});
+
+// resolve a file with the new resolver
+const context = {};
+const resolveContext = {};
+const lookupStartPath = '/Users/webpack/some/root/dir';
+const request = './path/to-look-up.js';
+myResolver.resolve({}, lookupStartPath, request, resolveContext, (err/*Error*/, filepath/*string*/) => {
+  // Do something with the path
+});
+```
+
+For more examples creating different types resolvers (sync/async, context, etc) see `lib/node.js`.

+| restrictions             | []                          | A list of resolve restrictions |
+| fileSystem               |                             | The file system which should be used |
+| resolver                 | undefined                   | A prepared Resolver to which the plugins are attached |
+
+## Plugins
+Similar to `webpack`, the core of `enhanced-resolve` functionality is implemented as individual plugins that are executed using [`Tapable`](https://github.com/webpack/tapable). 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()]
+  ...
+},
+```

+# Tapable
+
+The tapable package expose many Hook classes, which can be used to create hooks for plugins.
+
+``` javascript
+const {
+	SyncHook,
+	SyncBailHook,
+	SyncWaterfallHook,
+	SyncLoopHook,
+	AsyncParallelHook,
+	AsyncParallelBailHook,
+	AsyncSeriesHook,
+	AsyncSeriesBailHook,
+	AsyncSeriesWaterfallHook
+ } = require("tapable");
+```
+
+## Installation
+
+``` shell
+npm install --save tapable
+```
+
+## Usage
+
+All Hook constructors take one optional argument, which is a list of argument names as strings.
+
+``` js
+const hook = new SyncHook(["arg1", "arg2", "arg3"]);
+```
+
+The best practice is to expose all hooks of a class in a `hooks` property:
+
+``` js
+class Car {
+	constructor() {
+		this.hooks = {
+			accelerate: new SyncHook(["newSpeed"]),
+			brake: new SyncHook(),
+			calculateRoutes: new AsyncParallelHook(["source", "target", "routesList"])
+		};
+	}
+
+	/* ... */
+}
+```
+
+Other people can now use these hooks:
+
+``` js
+const myCar = new Car();
+
+// Use the tap method to add a consument
+myCar.hooks.brake.tap("WarningLampPlugin", () => warningLamp.on());
+```
+
+It's required to pass a name to identify the plugin/reason.
+
+You may receive arguments:
+
+``` js
+myCar.hooks.accelerate.tap("LoggerPlugin", newSpeed => console.log(`Accelerating to ${newSpeed}`));
+```
+
+For sync hooks, `tap` is the only valid method to add a plugin. Async hooks also support async plugins:
+
+``` js
+myCar.hooks.calculateRoutes.tapPromise("GoogleMapsPlugin", (source, target, routesList) => {
+	// return a promise
+	return google.maps.findRoute(source, target).then(route => {
+		routesList.add(route);
+	});
+});
+myCar.hooks.calculateRoutes.tapAsync("BingMapsPlugin", (source, target, routesList, callback) => {
+	bing.findRoute(source, target, (err, route) => {
+		if(err) return callback(err);
+		routesList.add(route);
+		// call the callback
+		callback();
+	});
+});
+
+// You can still use sync plugins
+myCar.hooks.calculateRoutes.tap("CachedRoutesPlugin", (source, target, routesList) => {
+	const cachedRoute = cache.get(source, target);
+	if(cachedRoute)
+		routesList.add(cachedRoute);
+})
+```
+
+The class declaring these hooks need to call them:
+
+``` js
+class Car {
+	/* ... */
+
+	setSpeed(newSpeed) {
+		this.hooks.accelerate.call(newSpeed);
+	}
+
+	useNavigationSystemPromise(source, target) {
+		const routesList = new List();
+		return this.hooks.calculateRoutes.promise(source, target, routesList).then(() => {
+			return routesList.getRoutes();
+		});
+	}
+
+	useNavigationSystemAsync(source, target, callback) {
+		const routesList = new List();

+```
+
+The Hook will compile a method with the most efficient way of running your plugins. It generates code depending on:
+* The number of registered plugins (none, one, many)
+* The kind of registered plugins (sync, async, promise)
+* The used call method (sync, async, promise)
+* The number of arguments
+* Whether interception is used
+
+This ensures fastest possible execution.
+
+## Hook types
+
+Each hook can be tapped with one or several functions. How they are executed depends on the hook type:
+
+* Basic hook (without “Waterfall”, “Bail” or “Loop” in its name). This hook simply calls every function it tapped in a row.
+
+* __Waterfall__. A waterfall hook also calls each tapped function in a row. Unlike the basic hook, it passes a return value from each function to the next function.
+
+* __Bail__. A bail hook allows exiting early. When any of the tapped function returns anything, the bail hook will stop executing the remaining ones.
+
+* __Loop__. TODO
+
+Additionally, hooks can be synchronous or asynchronous. To reflect this, there’re “Sync”, “AsyncSeries”, and “AsyncParallel” hook classes:
+
+* __Sync__. A sync hook can only be tapped with synchronous functions (using `myHook.tap()`).
+
+* __AsyncSeries__. An async-series hook can be tapped with synchronous, callback-based and promise-based functions (using `myHook.tap()`, `myHook.tapAsync()` and `myHook.tapPromise()`). They call each async method in a row.
+
+* __AsyncParallel__. An async-parallel hook can also be tapped with synchronous, callback-based and promise-based functions (using `myHook.tap()`, `myHook.tapAsync()` and `myHook.tapPromise()`). However, they run each async method in parallel.
+
+The hook type is reflected in its class name. E.g., `AsyncSeriesWaterfallHook` allows asynchronous functions and runs them in series, passing each function’s return value into the next function.
+
+
+## Interception
+
+All Hooks offer an additional interception API:
+
+``` js
+myCar.hooks.calculateRoutes.intercept({
+	call: (source, target, routesList) => {
+		console.log("Starting to calculate routes");
+	},
+	register: (tapInfo) => {
+		// tapInfo = { type: "promise", name: "GoogleMapsPlugin", fn: ... }
+		console.log(`${tapInfo.name} is doing its job`);
+		return tapInfo; // may return a new tapInfo object
+	}
+})
+```
+
+**call**: `(...args) => void` Adding `call` to your interceptor will trigger when hooks are triggered. You have access to the hooks arguments.
+
+**tap**: `(tap: Tap) => void` Adding `tap` to your interceptor will trigger when a plugin taps into a hook. Provided is the `Tap` object. `Tap` object can't be changed.
+
+**loop**: `(...args) => void` Adding `loop` to your interceptor will trigger for each loop of a looping hook.
+
+**register**: `(tap: Tap) => Tap | undefined` Adding `register` to your interceptor will trigger for each added `Tap` and allows to modify it.
+
+## Context
+
+Plugins and interceptors can opt-in to access an optional `context` object, which can be used to pass arbitrary values to subsequent plugins and interceptors.
+
+``` js
+myCar.hooks.accelerate.intercept({
+	context: true,
+	tap: (context, tapInfo) => {
+		// tapInfo = { type: "sync", name: "NoisePlugin", fn: ... }
+		console.log(`${tapInfo.name} is doing it's job`);
+
+		// `context` starts as an empty object if at least one plugin uses `context: true`.
+		// If no plugins use `context: true`, then `context` is undefined.
+		if (context) {
+			// Arbitrary properties can be added to `context`, which plugins can then access.
+			context.hasMuffler = true;
+		}
+	}
+});
+
+myCar.hooks.accelerate.tap({
+	name: "NoisePlugin",
+	context: true
+}, (context, newSpeed) => {
+	if (context && context.hasMuffler) {
+		console.log("Silence...");
+	} else {
+		console.log("Vroom!");
+	}
+});
+```
+
+## HookMap
+
+A HookMap is a helper class for a Map with Hooks
+
+``` js
+const keyedHook = new HookMap(key => new SyncHook(["arg"]))
+```
+
+``` js
+keyedHook.tap("some-key", "MyPlugin", (arg) => { /* ... */ });
+keyedHook.tapAsync("some-key", "MyPlugin", (arg, callback) => { /* ... */ });
+keyedHook.tapPromise("some-key", "MyPlugin", (arg) => { /* ... */ });
+```
+
+``` js
+const hook = keyedHook.get("some-key");
+if(hook !== undefined) {
+	hook.callAsync("arg", err => { /* ... */ });
+}
+```
+
+## Hook/HookMap interface
+
+Public:
+
+``` ts
+interface Hook {
+	tap: (name: string | Tap, fn: (context?, ...args) => Result) => void,
+	tapAsync: (name: string | Tap, fn: (context?, ...args, callback: (err, result: Result) => void) => void) => void,
+	tapPromise: (name: string | Tap, fn: (context?, ...args) => Promise<Result>) => void,
+	intercept: (interceptor: HookInterceptor) => void
+}
+
+interface HookInterceptor {
+	call: (context?, ...args) => void,
+	loop: (context?, ...args) => void,
+	tap: (context?, tap: Tap) => void,
+	register: (tap: Tap) => Tap,
+	context: boolean
+}
+
+interface HookMap {
+	for: (key: any) => Hook,
+	tap: (key: any, name: string | Tap, fn: (context?, ...args) => Result) => void,
+	tapAsync: (key: any, name: string | Tap, fn: (context?, ...args, callback: (err, result: Result) => void) => void) => void,
+	tapPromise: (key: any, name: string | Tap, fn: (context?, ...args) => Promise<Result>) => void,
+	intercept: (interceptor: HookMapInterceptor) => void
+}
+
+interface HookMapInterceptor {
+	factory: (key: any, hook: Hook) => Hook
+}
+
+interface Tap {
+	name: string,
+	type: string
+	fn: Function,
+	stage: number,
+	context: boolean
+}
+```
+
+Protected (only for the class containing the hook):
+
+``` ts
+interface Hook {
+	isUsed: () => boolean,
+	call: (...args) => Result,
+	promise: (...args) => Promise<Result>,
+	callAsync: (...args, callback: (err, result: Result) => void) => void,
+}
+
+interface HookMap {
+	get: (key: any) => Hook | undefined,
+	for: (key: any) => Hook
+}
+```
+
+## MultiHook
+
+A helper Hook-like class to redirect taps to multiple other hooks:
+
+``` js
+const { MultiHook } = require("tapable");
+
+this.hooks.allHooks = new MultiHook([this.hooks.hookA, this.hooks.hookB]);
+```
