# @farmfe/plugin-strip

🍣 A Farm rust plugin to remove `debugger` statements and functions like `assert.equal` and `console.log` from your code.

## Requirements

This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v18.0.0+) and Farm v1.0.0+.

## Install

Using npm:

```bash
npm i @farmfe/plugin-strip
```

## Usage

Create a `farm.config.js` [configuration file](https://www.farmfe.org/docs/config/configuring-farm) and import the plugin:

```js
import { defineConfig } from '@farmfe/core';
import strip from '@farmfe/plugin-strip-darwin-arm64';

export default defineConfig({
  // ...
  plugins: [
    [
      strip({
        // plugin options
        functions:[ 'console.*', 'assert.*' ],
        labels: ['unittest']
      })
    ]
  ],
  // ...
});
```

## Options

### `include`

Type: `String | RegExp | Array[...String|RegExp]`<br>
Default: `['**/*.js']`<br>
Example: `include: '**/*.(mjs|js)',`<br>

A pattern, or array of patterns, which specify the files in the build the plugin should operate on.

### `exclude`

Type: `String | RegExp | Array[...String|RegExp]`<br>
Default: `[]`<br>
Example: `exlude: 'tests/**/*',`<br>

A pattern, or array of patterns, which specify the files in the build the plugin should _ignore_.

### `debugger`

Type: `Boolean`<br>
Default: `true`<br>
Example: `debugger: false,`<br>

If `true` instructs the plugin to remove debugger statements.

### `functions`

Type: `Array[...String]`<br>
Default: `[ 'console.*', 'assert.*' ]`<br>
Example: `functions: [ 'console.log', 'MyClass.Test' ],`<br>

Specifies the functions that the plugin will target and remove.

_Note: specifying functions that are used at the begining of a chain, such as 'a().b().c()', will result in '(void 0).b().c()' which will generate an error at runtime._

### `labels`

Type: `Array[...String]`<br>
Default: `[]`<br>
Example: `labels: ['unittest'],`<br>

Specifies the [labeled blocks or statements](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/label) that the plugin will target and remove.

_Note: the '**:**' is implied and should not be specified in the config._

### `sourceMap`

Type: `Boolean`<br>
Default: `true`<br>
Example: `sourceMap: false,`<br>

If `true`, instructs the plugin to update source maps accordingly after removing configured targets from the bundle.
