# Webpack Extension Reloader
A Webpack plugin to automatically reload browser extensions during development.
[](https://www.npmjs.com/package/webpack-ext-reloader)
[](https://github.com/SimplifyJobs/webpack-ext-reloader/actions?query=branch%3Amaster)
[](https://snyk.io/test/github/SimplifyJobs/webpack-ext-reloader/)
[](https://www.npmjs.com/package/webpack-ext-reloader)
## Installing
For npm:
```bash
npm install webpack-ext-reloader --save-dev
```
For yarn:
```bash
yarn add webpack-ext-reloader --dev
```
## What is this?
This is a webpack plugin that brings hot reloading functionality to WebExtensions, essentially resembling `webpack-dev-server` but for [WebExtensions](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions).
This project is a fork of [`webpack-extension-reloader`](https://github.com/rubenspgcavalcante/webpack-extension-reloader), maintained and updated by the team at Simplify. The goal is to continue supporting the latest version of webpack (`webpack-extension-reloader` only supports webpack v4) while introducing new improvements, such as HMR.
**Note**: This plugin does not support [**Hot Module Replacement (HMR)**](https://webpack.js.org/concepts/hot-module-replacement/) yet.
## How to use
### Using as a plugin
Add `webpack-ext-reloader` to the plugins section of your webpack configuration file. This plugin does not output the manifest; it might read it for information at most. For outputting not only the `manifest.json` but other static files as well, use `CopyWebpackPlugin`.
```js
const ExtReloader = require('webpack-ext-reloader');
plugins: [
new ExtReloader(),
new CopyWebpackPlugin([
{ from: "./src/manifest.json" },
{ from: "./src/popup.html" },
]),
]
```
You can point to your `manifest.json` file...
```js
plugins: [
new ExtReloader({
manifest: path.resolve(__dirname, "manifest.json")
}),
// ...
]
```
... or you can also use some extra options (the following are the default ones):
```js
// webpack.dev.js
module.exports = {
mode: "development", // The plugin is activated only if mode is set to development
watch: true,
entry: {
'content-script': './my-content-script.js',
background: './my-background-script.js',
popup: 'popup',
},
// ...
plugins: [
new ExtReloader({
port: 9090, // Which port use to create the server
reloadPage: true, // Force the reload of the page also
entries: { // The entries used for the content/background scripts or extension pages
contentScript: 'content-script',
background: 'background',
extensionPage: 'popup',
}
}),
// ...
]
}
```
**Note I**: Either `entry` or `manifest` is needed. If both are provided, the `entry` will override the information from `manifest.json`. If neither is provided, the default `entry` values (as shown above) are used.
Run your application with Webpack in watch mode:
```bash
NODE_ENV=development webpack --config myconfig.js --mode=development --watch
```
**Note II**: You need to set `--mode=development` to activate the plugin. If you didn't set it in the webpack.config.js already, you need to run with `--watch` since the plugin will be able to sign the extension only if webpack triggers the rebuild.
### Multiple Content Script and Extension Page support
If your extension uses more than one content script or extension page, like:
```js
entry: {
'my-first-content-script': './my-first-content-script.js',
'my-second-content-script': './my-second-content-script.js',
background: './my-background-script.js',
'popup': './popup.js',
'options': './options.js',
}
```
Use the `entries.contentScript` or `entries.extensionPage` options as an array:
```js
plugins: [
new ExtReloader({
entries: {
contentScript: ['my-first-content-script', 'my-second-content-script'],
background: 'background',
extensionPage: ['popup', 'options'],
}
}),
]
```
### CLI
If you'd rather skip the plugin setup, you can use the client included with the package. Install the package globally or use `npx`:
```bash
npx webpack-ext-reloader
```
If run directly, it will use the default configurations. But if you'd like customization:
```bash
npx webpack-ext-reloader --config wb.config.js --port 9080 --no-page-reload --content-script my-content.js --background bg.js --extension-page popup.js
```
For **multiple** content scripts or extension pages, separate the options with commas (without spaces):
```bash
npx webpack-ext-reloader --content-script my-first-content.js,my-second-content.js --extension-page popup.js,options.js
```
### Client options
| Name | Default | Description |
| ----------------- | ----------------- | ----------------------------------------------------------------- |
| --help | | Shows help |
| --config | webpack.config.js | Path to the webpack configuration file |
| --port | 9090 | Port to run the server on |
| --manifest | | Path to the extension's **manifest.json** file |
| --content-script | content-script | **Entry/entries** name(s) for the content script(s) |
| --background | background | **Entry** name for the background script |
| --extension-page | popup | **Entry/entries** name(s) for the extension page(s) |
| --no-page-reload | | Disable auto-reloading of all **pages** running the plugin |
Whenever content or background scripts are modified, the extension will reload.
**Note**: This plugin only works in **development** mode. Remember to set the NODE_ENV before running the commands above.
