A CLI dashboard for your webpack dev server

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

ℹ️Note: 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.

webpack-dashboard@^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:

// Import the plugin:constDashboardPlugin=require("webpack-dashboard/plugin");// Add it to your webpack configuration plugins.module.exports={// ...plugins:[newDashboardPlugin()];// ...};

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.

More configuration customization examples can be found in ourgetting started guide.

For example, if you want to use a custom port ofwebpack-dashboard to communicate between its plugin and CLI tool, you would first set the number in the options object in webpack configuration:

plugins:[newDashboardPlugin({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 isnot already in use. You should not choose one that is being used bywebpack-dev-server /devServer or any other process. Instead, pick one that isonly forwebpack-dashboard and pair that up in the plugin configuration and CLI port flag.

Finally, start your server using whatever command you have set up. Either you havenpm run dev ornpm start pointed atnode devServer.js or something along those lines.

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

macOS →Webpack Dashboard works in Terminal, iTerm 2, and Hyper. For mouse events, like scrolling, in Terminal you will need to ensureView → 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⌥ Opt key. To select a block of text hold the⌥ Opt +⌘ Cmd 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 useBlessed. The main log can be scrolled using the↑,↓,Page Up, andPage Down 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⇧ Shift key.

• -c, --color [color] - Custom ANSI color for your dashboard
• -m, --minimal - Runs the dashboard in minimal mode
• -t, --title [title] - Set title of terminal window
• -p, --port [port] - Custom port for socket communication server
• -a, --include-assets [string prefix] - Limit display to asset names matching string prefix (option can be repeated and is concatenated tonew DashboardPlugin({ includeAssets }) options array)

[command] - The command you want to run, i.e.webpack-dashboard -- node index.js

• host - Custom host for connection the socket client
• port - Custom port for connecting the socket client
• includeAssets - Limit display to asset names matching string prefix or regex (Array<String | RegExp>)
• handler - Plugin handler method, i.e.dashboard.setData

Note: you can also just pass a function in as an argument, which then becomes the handler, i.e.new DashboardPlugin(dashboard.setData)

We've standardized our local development process forwebpack-dashboard on usingyarn. We recommend usingyarn 1.10.x+, as these versions include theintegrity 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.

yarnyarn dev

We re-use a small handful of the fixtures frominspectpack so that you can work locally on the dashboard while simulating commonnode_modules dependency issues you might face in the wild. These live in/examples.

To change the example you're working against, simply alter theEXAMPLE env variable in thedev script inpackage.json to match the scenario you want to run in/examples. For example, if you want to run thetree-shaking example, change thedev 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 WEBPACK_MODE=production \  node bin/webpack-dashboard.js -- \  webpack-cli --config examples/config/webpack.config.js --watch

Then just runyarn dev to get up and running. PRs are very much appreciated!
