web-ext-plugin

A webpack plugin for running web-ext

Basic usage

$ npm install --save-dev web-ext-plugin

# Or for yarn
$ yarn add -D web-ext-plugin

webpack.config.mjs

import WebExtPlugin from 'web-ext-plugin';

module.exports = {
  plugins: [new WebExtPlugin({ sourceDir: 'extension-dist' })],
};

Running webpack by itself will build the extension, effectively running web-ext build on the output of your Webpack build.

To run the extension in a browser (including automatic reloading when using Firefox), i.e. to run web-ext run, you will need to start Webpack in watch mode using webpack -w.

Options

• artifactsDir (optional) - The folder where artifacts are built stored. Defaults to <sourceDir>/web-ext-artifacts. You typically won't need to alter this.

• browserConsole (optional) - A boolean indicating if the browser console should be shown on load.

  Defaults to false.

• buildPackage (optional) - A boolean indicating if a zip file of the extension should be generated.

  The name of the .zip file is taken from the name field in the extension manifest unless outputFilename is set.

  Defaults to false.

• chromiumBinary (optional) - A path to a specific version of a Chromium browser to run. The value is an absolute path to the browser executable or an alias string.

• chromiumProfile (optional) - A path to a custom Chromium profile to use.

• firefox (optional) - A path to a specific version of Firefox to run. The value is an absolute path to the Firefox executable or an alias string.

• firefoxProfile (optional) - A specific Firefox profile to use. This may be either a profile name or the path to a profile directory. If this is not set a new profile is generated each time.

• keepProfileChanges (optional) - A boolean value indicating if the profile specified by firefoxProfile.

  Defaults to false.

  See the notes for the --keep-profile-changes flag from the web-ext run documentation. Specifically, this should not be used together with a profile you later use for browsing. It is, however, useful if you want to force the profile in a specific location to be written to (e.g. for testing out-of-disk space situations).

• outputFilename (optional) - The name of the .zip file to write when buildPackage is true.

  If this is not set the name of the .zip file is taken from the name field in the extension manifest.

• overwriteDest (optional) - A boolean value indicating if the package built when buildPackage is true, should overwrite an existing package at the same location.

  Without this option, web-ext will exit in error if the destination file already exists.

  Defaults to false.

• profileCreateIfMissing (optional) - A boolean value indicating if the profile specified by firefoxProfile should be created if it does not exist.

  Note that if this is specified, firefoxProfile is treated as meaning a directory path (not a profile name).

  Defaults to false.

• runLint (optional) - A boolean indicating if web-ext lint should be run as part of building the extension.

  Defaults to true.

• selfHosted (optional) - If true declares that your extension will be self-hosted and disables lint messages related to hosting on addons.mozilla.org.

  Defaults to false.

• sourceDir (optional) - The folder where webpack is building your extension to. Typically this will be where you have configured output.path to point to. Relative paths will be resolved relative to the webpack.config.js file.

  Defaults to the same folder as the webpack.config.js file.

• startUrl (optional) - A URL or array of URLs to load on startup.

• target (optional) - One of firefox-desktop, firefox-android, or chromium or an array of such values.

  Defaults to firefox-desktop.

  See the documentation for the --target option of web-ext run.
