[yarn](https://yarnpkg.com)\n\n```\n$ yarn add dush-better-use\n```\n\n## Usage\n\u003e For more use-cases see the [tests](test.js)\n\n```js\nconst dushBetterUse = require('dush-better-use')\n```\n\n## API\n\n### [betterUse](index.js#L37)\n\u003e Overrides the default [dush][]/[minibase][]/[base][] `.use` method to support named plugins and to have better error handling. It also adds/registers the [minibase-is-registered][] plugin if not included already, so you will have `.isRegistered` method too. This plugin emits `error` event if something fail in plugin, instead of throwing.\n\n**Params**\n\n* `opts` **{Object}**: no options currently    \n* `returns` **{Function}**: a plugin function that should be passed to `.use` method  \n\n**Example**\n\n```js\nvar dush = require('dush')\nvar betterUse = require('dush-better-use')\n\nvar app = dush()\napp.use(betterUse())\n```\n\n### [.use](index.js#L89)\n\u003e Calls `fn` plugin immediately once, if `name` is string it registers it as \"named\" plugin so you can find its name at `app.registered` cache. It also emits `error` event if plugin `fn` throws.\n\n**Params**\n\n* `name` **{String|Function}**: name of the plugin or `fn` plugin function    \n* `fn` **{Function|Object}**: a plugin function, called immedately; or `options` object    \n* `options` **{Object}**: direclty passed as 2nd argument to `fn`    \n* `returns` **{Object}**: self \"app\" for chaining  \n\n**Example**\n\n```js\nvar called = 0\n\nfunction plugin (app) {\n  app.foo = 123\n  called++\n}\n\napp.use('foobar', plugin)\napp.use('foobar', plugin)\napp.use('foobar', plugin)\n\nconsole.log(called) // =\u003e 1\nconsole.log(app.foo) // =\u003e 123\nconsole.log(app.registered) // =\u003e { 'foobar': true }\n\n// if something fails in a plugin\n// it emits `error` event\napp.once('error', (err) =\u003e {\n  console.log('ERR!', err.toString()) // =\u003e Error: sadly error\n})\napp.use((app) =\u003e {\n  throw new Error('sadly error')\n})\n```\n\n## Related\n- [dush-methods](https://www.npmjs.com/package/dush-methods): Plugin for `dush` and anything based on it.

For bugs and feature requests, [please create an issue][open-issue-url].  \nPlease read the [contributing guidelines][contributing-url] for advice on opening issues, pull requests, and coding standards.  \nIf you need some help and can spent some cash, feel free to [contact me at CodeMentor.io][codementor-url] too.\n\n**In short:** If you want to contribute to that project, please follow these things\n\n1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md][changelogmd-url] and [.verb.md](.verb.md) files. See [\"Building docs\"](#building-docs) section.\n2. Ensure anything is okey by installing the dependencies and run the tests. See [\"Running tests\"](#running-tests) section.\n3. 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.\n4. Do NOT bump the version in package.json. For that we use `npm run release`, which is [standard-version][] and follows Conventional Changelog idealogy.\n\nThanks a lot! :)\n\n## Building docs\nDocumentation 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\n\n```\n$ npm install verbose/verb#dev verb-generate-readme --global \u0026\u0026 verb\n```\n\n_Please don't edit the README directly. Any changes to the readme must be made in [.verb.md](.verb.md)._\n\n## Running tests\nClone repository and run the following in that cloned directory\n\n```\n$ npm install \u0026\u0026 npm test\n```\n\n## Author\n**Charlike Mike Reagent**\n\n+ [github/tunnckoCore](https://github.com/tunnckoCore)\n+ [twitter/tunnckoCore](https://twitter.com/tunnckoCore)\n+ [codementor/tunnckoCore](https://codementor.io/tunnckoCore)\n\n## License\nCopyright © 2017, [Charlike Mike Reagent](https://i.am.charlike.online).
