## README

# Autoprefixer for Ember CLI [![Build Status](https://travis-ci.org/kimroen/ember-cli-autoprefixer.svg?branch=master)](https://travis-ci.org/kimroen/ember-cli-autoprefixer)
This addon runs the styles of your Ember CLI-project through
Autoprefixer.

## Install
To install, run

```
ember install ember-cli-autoprefixer
```

## Options
This addon first consumes your browser list config from `config/targets.js`.  This is the browser list for Babel.

You can manually configure what browsers to target for autoprefixer only.  Add the target browsers to your package.json
as per https://github.com/browserslist/browserslist#readme, add a `.browserslistrc` file, or configure `overrideBrowsersList`
in `ember-cli-build.js`.

```js
// ember-cli-build.js
var app = new EmberApp(defaults, {
  autoprefixer: {
    overrideBrowserslist: ['IE11'],
    cascade: false
  }
});
```

This would prefix styles as required by the two latest version of ios, and disable the cascade (see below).

You can disable Autoprefixer by passing in `enabled: false`.

Other options would also go here along with `overrideBrowserslist`, `enabled` and `cascade`.

You can read more about these settings and others [over on the Autoprefixer page](https://github.com/postcss/autoprefixer#options).

## Note on using with ember-cli-sass

Autoprefixer doesn't play well with `.css.map` files, but it will work with embedded source maps. This means there are two options.

If you want to disable CSS sourcemaps from ember-cli-sass update `ember-cli-build.js` to

```js
  sassOptions: {
    // This tells ember-cli-sass to avoid generating the sourcemap file (like vendor.css.map)
    sourceMap: false
  }
```

Alternatively, you may use embedded source maps.  So we tell `ember-cli-sass` to embed the sourcemaps and then turn on sourcemaps with autoprefixer which will update the embedded sourcemap after adding prefixes.

```js
  sassOptions: {
    sourceMap: true,
    sourceMapEmbed: true
  },
  autoprefixer: {
    enabled: true,
    cascade: true,
    sourcemap: true
  }
```

Also note you can optionally disable in production!

```js
  const envIsProduction = (process.env.EMBER_ENV === 'production');

  ...

  sassOptions: {
    sourceMap: !envIsProduction,
    sourceMapEmbed: !envIsProduction
  },
  autoprefixer: {
    enabled: true,
    cascade: true,
    sourcemap: !envIsProduction
  }
```
