# Unused Exports

Tool for identifying and reporting unused exports found in ECMAScript/JavaScript code.

You may think of it as ESLint `no-unused-vars` rule, but for the whole project scope.

Tool uses [Babel parser](https://babeljs.io/docs/en/babel-parser) to parse source code. You can provide custom parser options using config file.

## Instalation

```shell

npm install -g js-unused-exports

```

## Usage

```pre

Usage: js-unused-exports [options]

 E.g.: js-unused-exports --config "unused-exports-config.json"

Options:

  -v, --version        output the version number

  -c, --config [path]  path to the JSON config file

  -o --out-dir [path]  path to print scan results as JSON

  -f, --fix            automatically remove "export" directive where possible

  -h, --help           output usage information

  ```

## Configuration

```javascript

{

  // Root project directory or CWD (default)

  projectRoot: '',

  // Source paths relative to project root

  sourcePaths: ['src/**/*.js'],

  // Patterns for files that should be ignored

  ignorePaths: [],

  // Test file patterns

  testPaths: [

    'src/**/*.spec.js'

  ],

  // Import patterns to ignore

  ignoreImportPatterns: [ '(png|gif|jpg|jpeg|css|scss)$' ],

  // Export patterns to ignore

  ignoreExportPatterns: [ '(stories)' ],

  // If you use alias in you codebase you can specify them here, e.g.:

  aliases: {

    components: 'src/components'

  },

  // @babel/parser options for parsing source code

  // https://babeljs.io/docs/en/babel-parser

  parserOptions: {

    sourceType: 'module',

    plugins: [

      'objectRestSpread',

      'jsx',

      'flow',

      'classProperties',

      'decorators-legacy',

      'exportDefaultFrom'

    ]

  }
