A CLI dashboard for your webpack dev server

What's this all about?

When using webpack, especially for a dev server, you are probably used to seeing something like this:

That's cool, but it's mostly noise and scrolly and not super helpful. This plugin changes that. Now when you run your dev server, you basically work at NASA:


$ npm install --save-dev webpack-dashboard # ... or ... $ yarn add --dev webpack-dashboard

ℹ️ Note: You can alternatively globally install the dashboard (e.g.

npm install -g webpack-dashboard

) for use with any project and everything should work the same.


**``` [email protected]^3.0.0

 requires Node 8 or above.** Previous versions support down to Node 6.

First, import the plugin and add it to your webpack config, or apply it to your compiler:

// Import the plugin: var DashboardPlugin = require("webpack-dashboard/plugin"); // If you aren't using express, add it to your webpack configs plugins section: plugins: [new DashboardPlugin()]; // If you are using an express based dev server, add it with compiler.apply compiler.apply(new DashboardPlugin());

Then, modify your dev server start script previously looked like:

"scripts": { "dev": "node index.js", # OR "dev": "webpack-dev-server", # OR "dev": "webpack", }

You would change that to:

"scripts": { "dev": "webpack-dashboard -- node index.js", # OR "dev": "webpack-dashboard -- webpack-dev-server", # OR "dev": "webpack-dashboard -- webpack", }

Now you can just run your start script like normal, except now, you are awesome. Not that you weren't before. I'm just saying. More so.

#### Customizations

More configuration customization examples can be found in our [getting started]( guide.

For example, if you want to use a custom port of


 to communicate between its plugin and CLI tool, you would first set the number in the options object in webpack configuration:

plugins: [new DashboardPlugin({ port: 3001 })];

Then, you would pass it along to the CLI to match:

$ webpack-dashboard --port 3001 -- webpack

> ⚠️ **Warning**: When choosing a custom port, you need to find one that is **not** already in use. You should not choose one that is being used by
> ```
> webpack-dev-server
> ```
> / 
> ```
> devServer
> ```
> or any other process. Instead, pick one that is **only** for 
> ```
> webpack-dashboard
> ```
> and pair that up in the plugin configuration and CLI port flag.

### Run it

Finally, start your server using whatever command you have set up. Either you have

npm run dev


npm start

 pointed at 

node devServer.js

 or something along those lines.

Then, sit back and pretend you're an astronaut.

### Supported Operating Systems and Terminals

**macOS →**Webpack Dashboard works in Terminal, iTerm 2, and Hyper. For mouse events, like scrolling, in Terminal you will need to ensure _View → Enable Mouse Reporting_ is enabled. This is supported in macOS El Capitan, Sierra, and High Sierra. In iTerm 2, to select full rows of text hold the <kbd>⌥ Opt</kbd> key. To select a block of text hold the <kbd>⌥ Opt</kbd> + <kbd>⌘ Cmd</kbd> key combination.

**Windows 10 →** Webpack Dashboard works in Command Prompt, PowerShell, and Linux Subsystem for Windows. Mouse events are not supported at this time, as discussed further in the documentation of the underlying terminal library we use [Blessed]( The main log can be scrolled using the <kbd>↑</kbd>, <kbd>↓</kbd>, <kbd>Page Up</kbd>, and <kbd>Page Down</kbd> keys.

**Linux →** Webpack Dashboard has been verified in the built-in terminal app for Debian-based Linux distributions such as Ubuntu or Mint. Mouse events and scrolling are supported automatically. To highlight or select lines hold the <kbd>⇧ Shift</kbd> key.

### Local Development

We've standardized our local development process for


 on using 


. We recommend using 

yarn 1.10.x+

, as these versions include the 


 checksum. The checksum helps to verify the integrity of an installed package before its code is executed. 🚀

To run this repo locally against our provided examples, take the usual steps.

yarn yarn dev

We re-use a small handful of the fixtures from [


]( so that you can work locally on the dashboard while simulating common


 dependency issues you might face in the wild. These live in 



To change the example you're working against, simply alter the


 env variable in the 


 script in 


 to match the scenario you want to run in 


. For example, if you want to run the 


 example, change the 


 script from this:

cross-env EXAMPLE=duplicates-esm node bin/webpack-dashboard.js -- webpack-cli --config examples/config/webpack.config.js --watch

to this:

cross-env EXAMPLE=tree-shaking node bin/webpack-dashboard.js -- webpack-cli --config examples/config/webpack.config.js --watch

Then just run

yarn dev

 to get up and running. PRs are very much appreciated!
### Publishing

When it comes time to publish a new version of




, authorized users can take the following steps:

Ensure build passes all CI checks. git pull origin master yarn check-ci # Version the change. We use semantic versioning. yarn version --

Publish to npm.

yarn publish

Commit the release tag to source.

git push && git push --tags

Please also be sure to update

 with release notes and draft the release on GitHub. We loosely follow the [Keep a Changelog]( spec with categories for 








, and 


. All releases should also include 

Migration Instructions

``` for adopting the new release.
