# snowpack-plugin-closure-compiler
Snowpack plugin that processes JavaScript assets through the [Closure Compiler](https://developers.google.com/closure/compiler), reducing file sizes and performing static code analysis.
## Requirements
This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Snowpack v2.0.0+.
## Install
Using npm:
```console
npm install --save-dev snowpack-plugin-closure-compiler
```
## Usage
Create a `snowpack.config.js` [configuration file](https://www.snowpack.dev/reference/configuration) and import the plugin:
```js
const dsv = require('snowpack-plugin-dsv');
module.exports = {
mount: {
public: { url: '/', static: true },
src: { url: '/dist' },
},
plugins: ['snowpack-plugin-closure-compiler', {
compilationLevel: "SIMPLE",
outputFile: "main.js",
bundle: false
}],
};
```
## Options
### `bundle`
Type: `boolean`
Default: `true`
The Closure Compiler can bundle all JavaScript files into and this is the default processing for the plugin. If JavaScript files need to not be bundled, use `false`.
### `outputFile`
Type: `string`
Default: `index.js`
Specify resource name after compilation, placed inside of `mount.src.url` directory.
### `compilationLevel`
Type: `string`
Default: `SIMPLE`
Determines type of processing performed by Closure Compiler - specify one of `BUNDLE`, `WHITESPACE_ONLY`, `SIMPLE`, `ADVANCED`
### `languageIn`
Type: `string`
Default: `ECMASCRIPT_NEXT`
Specifies what the most recent level of ECMAScript used in the source code. One of the following: `ECMASCRIPT3`, `ECMASCRIPT5`, `ECMASCRIPT5_STRICT`, `ECMASCRIPT_2015`, `ECMASCRIPT_2016`, `ECMASCRIPT_2017`, `ECMASCRIPT_2018`, `ECMASCRIPT_2019`, `STABLE`, `ECMASCRIPT_NEXT`
### `languageOut`
Type: `string`
Default: `ECMASCRIPT5`
Determines ECMAScript version of output file - use one of the values referenced in the `languageIn` property.
