+# Mitt
+
+> Tiny 200b functional event emitter / pubsub.
+
+-   **Microscopic:** weighs less than 200 bytes gzipped
+-   **Useful:** a wildcard `"*"` event type listens to all events
+-   **Familiar:** same names & ideas as [Node's EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter)
+-   **Functional:** methods don't rely on `this`
+-   **Great Name:** somehow [mitt](https://npm.im/mitt) wasn't taken
+
+Mitt was made for the browser, but works in any JavaScript runtime. It has no dependencies and supports IE9+.

+
+## Install
+
+This project uses [node](http://nodejs.org) and [npm](https://npmjs.com). Go check them out if you don't have them locally installed.
+
+```sh
+$ npm install --save mitt
+```
+
+Then with a module bundler like [rollup](http://rollupjs.org/) or [webpack](https://webpack.js.org/), use as you would anything else:
+
+```javascript
+// using ES6 modules
+import mitt from 'mitt'
+
+// using CommonJS modules
+var mitt = require('mitt')
+```
+
+The [UMD](https://github.com/umdjs/umd) build is also available on [unpkg](https://unpkg.com):
+
+```html
+<script src="https://unpkg.com/mitt/dist/mitt.umd.js"></script>
+```
+
+You can find the library on `window.mitt`.
+
+## Usage
+
+```js
+import mitt from 'mitt'
+
+const emitter = mitt()
+
+// listen to an event
+emitter.on('foo', e => console.log('foo', e) )
+
+// listen to all events
+emitter.on('*', (type, e) => console.log(type, e) )
+
+// fire an event
+emitter.emit('foo', { a: 'b' })
+
+// working with handler references:
+function onFoo() {}
+emitter.on('foo', onFoo)   // listen
+emitter.off('foo', onFoo)  // unlisten
+```
+
+### Typescript
+
+```ts
+import mitt from 'mitt';
+const emitter: mitt.Emitter = mitt();
+```
+

+
+Mitt: Tiny (~200b) functional event emitter / pubsub.
+
+**Parameters**
+
+-   `all` **EventHandlerMap** 
+
+Returns **Mitt** 
+
+### on
+
+Register an event handler for the given type.
+
+**Parameters**
+
+-   `type` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Type of event to listen for, or `"*"` for all events
+-   `handler` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** Function to call in response to given event
+
+### off
+
+Remove an event handler for the given type.
+
+**Parameters**
+
+-   `type` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Type of event to unregister `handler` from, or `"*"`
+-   `handler` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** Handler function to remove
+
+### emit
+
+Invoke all handlers for the given type.
+If present, `"*"` handlers are invoked after type-matched handlers.
+
+**Parameters**
+
+-   `type` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** The event type to invoke
+-   `evt` **Any?** Any value (object is recommended and powerful), passed to each handler
+
+## Contribute
+
+First off, thanks for taking the time to contribute!
+Now, take a moment to be sure your contributions make sense to everyone else.
+
+Development Start:
+
+This project is typed with Flow Type annotations. To ensure you have the proper typings for this project run
+
+`flow-typed install`
+
+### Reporting Issues
+
+Found a problem? Want a new feature? First of all see if your issue or idea has [already been reported](../../issues).
+If don't, just open a [new clear and descriptive issue](../../issues/new).
+
+### Submitting pull requests
+
+Pull requests are the greatest contributions, so be sure they are focused in scope, and do avoid unrelated commits.
+
+-   Fork it!
+-   Clone your fork: `git clone https://github.com/<your-username>/mitt`
+-   Navigate to the newly cloned directory: `cd mitt`
+-   Create a new branch for the new feature: `git checkout -b my-new-feature`
+-   Install the tools necessary for development: `npm install`
+-   Make your changes.
+-   Commit your changes: `git commit -am 'Add some feature'`
+-   Push to the branch: `git push origin my-new-feature`
