> {%= description %}

_You might also be interested in [mitt][] - a 200 bytes event emitter. It has strict policy 
to stay exactly below 200b with no compromises, so has lack of support
for few things and that's why `dush` exists._

## Quality 👌

> By using [commitizen][czfriendly-url] and [conventional commit messages][conventional-messages-url], 
maintaining meaningful [ChangeLog][changelogmd-url] 
and commit history based on [global conventions][conventions-url], 
following [StandardJS][standard-url] code style through [ESLint][eslint-url] and
having always up-to-date dependencies through integrations
like [GreenKeeper][gk-integration-url] and [David-DM][daviddm-url] service,
this package has top quality.

## Highlights :sparkles:

- **Microscopic:** Around ~400 bytes gzip + minify, including the UMD wrapper.
- **Functional:** Methods don't rely on `this` context.
- **Modern:** Work on latest JavaScript versions, but on Node.js 0.10 too.
- **Extensible:** Through simple plugins, for more customizations.
- **Compatibility:** Almost like Node's EventEmitter.
- **Compliant:** Can `.emit` events with multiple params.
- **Chaining:** Support all methods to be chainable.
- **Useful:** A wildcard `'*'` event type listens to all events.
- **Friendly:** Plays well with [browserify][], [webpack][] and browser users.
- **Bundled:** Available as ES6 Module, CommonJS and UMD.
- **Meaning:** [Hear it](https://translate.google.com/?hl=bg&tab=wT#en/bg/dush). It just means `shower` in Bulgarian.
- **Clean:** Does not mess with DOM or anything.

## Plugins

- [dush-router][] - Simple regex-based router with Express-like routing, for browser and nodejs
- [dush-promise][] - Makes `dush` a Deferred promise, centralized error handling
- [dush-methods][] - Adds `.define` and `.delegate` methods for defining non-enumerables
- [dush-options][] - Adds `.option` method and `app.options` property
- [dush-plugins](https://github.com/tunnckoCore/dush-plugins) - Upgrades the current plugin system with support for smart plugins
- [dush-tap-report][] - Produces TAP report, based on events such as `pass`, `fail`, `start` and `finish`
- [dush-better-use][] - Adds support for named plugins and better error handling
- [dush-no-chaining][] - Removes the support for chaining methods

## Install
Install with [npm](https://www.npmjs.com/)

```
$ npm install {%= name %} --save
```

or install using [yarn](https://yarnpkg.com)

```
$ yarn add {%= name %}
```

or using [unpkg](https://unpkg.com) CDN

```html
<script src="https://unpkg.com/dush/dist/dush.umd.js"></script>
```

> **Note:** Don't use Unpkg's short-hand endpoint `https://unpkg.com/dush`, 
since it points to CommonJS bundle.

## Usage

Modern `import`ing, using [rollup][] or [webpack][] bundler

```js
import dush from 'dush'
```

Node.js `require` as CommonJS module

```js
var dush = require('dush')
```

Old school in browsers, available at global scope

```html
<script>
  var emitter = dush()
</script>

## Contributing
Pull requests and stars are always welcome. For bugs and feature requests, [please create an issue][open-issue-url].  
Please read the [contributing guidelines][contributing-url] for advice on opening issues, pull requests, and coding standards.  
If you need some help and can spent some cash, feel free to [contact me at CodeMentor.io][codementor-url] too.

**In short:** If you want to contribute to that project, please follow these things

1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md][changelogmd-url] and [.verb.md](.verb.md) files. See ["Building docs"](#building-docs) section.
2. Ensure anything is okey by installing the dependencies and run the tests. See ["Running tests"](#running-tests) section.
3. Always use `npm run commit` to commit changes instead of `git commit`, because it is interactive and user-friendly. It uses [commitizen][] behind the scenes, which follows Conventional Changelog idealogy.
4. Do NOT bump the version in package.json. For that we use `npm run release`, which is [standard-version][] and follows Conventional Changelog idealogy.

Thanks a lot! :)

## Building docs
Documentation and that readme is generated using [verb-generate-readme][], which is a [verb][] generator, so you need to install both of them and then run `verb` command like that

```
$ npm install verbose/verb#dev verb-generate-readme --global && verb
```

_Please don't edit the README directly. Any changes to the readme must be made in [.verb.md](.verb.md)._

## Running tests
Clone repository and run the following in that cloned directory

```
$ npm install && npm test
```
