## Install

```sh
$ yarn add -D @ovh-ux/component-rollup-config
```

## Usage

```js
import configGenerator from '@ovh-ux/component-rollup-config';

// generate your configuration with global options
const config = configGenerator({
  input: './src/my-library.js',
});

// export desired list of target(s)
export default [
  // ES6 module
  config.es(),

  // CommonJS
  config.cjs(),

  // UMD (Universal Module Definition)
  config.umd({
    output: {
      globals: {
        angular: 'angular',
        jquery: '$',
      },
    },
  }),

  // IIFE (Immediately Invoked Function Expression)
  config.iife({
    output: {
      globals: {
        angular: 'angular',
        jquery: '$',
      },
    },
  }),
];
```

## Plugins

This configuration provides some plugins to facilitate loading and importing of ovh translations ; as well as a plugin to facilitate less imports.

### translation-ui-router

Handle `translations` property in ui-router state declaration to dynamically load ovh translations when state is resolved.

```js
// will import `./translations` and `../common/translations` during ui-router state resolve
$stateProvider.state('my-state', {
  url: 'some-template.html',
  translations: ['.', '../common'],
});
```

### translation-inject

Handle `@ngTranslationsInject` comment in order to facilitate dynamic import of ovh translations.

The format is as follows: `@ngTranslationsInject{:format} [translations]`

`translations` is multiple strings separated by a space

```js
// Load .translations and ../common/translations in json
angular
  .module('myModule', [])
  .run(/* @ngTranslationsInject ./translations ../common/translations */);

// Load .translations and ../common/translations in json
angular
  .module('myModule', [])
  .run(/* @ngTranslationsInject:json ./translations ../common/translations */);
```

```js
import angular from 'angular';

class MyController {
  /* @ngInject */
  constructor($injector) {
    this.$injector = $injector;
  }

  $onInit() {
    this.isLoading = true;
    return this.$injector
      .invoke(/* @ngTranslationsInject ./translations ./some/other/path */)
      .finally(() => {
        this.isLoading = false;
      });
  }
}

angular.module('myModule', []).controller('myController', MyController);
```

### Performance

Regarding the translations related plugins, it's possible to only process translations files for a single language. Please refer to the example below. This can be useful if you want faster builds in your development environment for example.

```js
import configGenerator from '@ovh-ux/component-rollup-config';

const config = configGenerator(
  {
    input: './src/my-library.js',
  },
  {
    translations: {
      languages: ['fr_FR', 'en_EN'], // only FR and EN translations will be provided
    },
  },
);

export default [config.cjs()];
```

You can also specify languages without modifying your rollup config by using the cli and passing the LANGUAGES environment variable. See the example below.

```sh
$ rollup -c --environment LANGUAGES:fr_FR
$ rollup -c --environment LANGUAGES:fr_FR-en_GB-en_US
```

## Test

```sh
$ yarn test
```
