strip

@rollup/plugin-strip

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

Requirements

This plugin requires an LTS Node version (v14.0.0+) and Rollup v1.20.0+.

Install

Using npm:

npm install @rollup/plugin-strip --save-dev

Usage

Create a rollup.config.js configuration file and import the plugin:

import strip from '@rollup/plugin-strip';

export default {
  input: 'src/index.js',
  output: {
    dir: 'output',
    format: 'cjs'
  },
  plugins: [
    strip({
      labels: ['unittest']
    })
  ]
};

Then call rollup either via the CLI or the API.

Options

include

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

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]
Default: []
Example: exlude: 'tests/**/*',

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

debugger

Type: Boolean
Default: true
Example: debugger: false,

If true instructs the plugin to remove debugger statements.

functions

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

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]
Default: []
Example: labels: ['unittest'],

Specifies the labeled blocks or statements that the plugin will target and remove.

Note: the ':' is implied and should not be specified in the config.

Example: sourceMap: false,

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