Awesome

✔ Display elegant progress bar while building or watch

✔ Support of multiple concurrent builds (useful for SSR)

✔ Pretty print filename and loaders

✔ Windows compatible

✔ Fully customizable using reporters

✔ Advanced build profiler

To begin, you'll need to install webpackbar:

# ✨ Auto-detect
npx nypm install webpackbar

# npm
npm install webpackbar

# yarn
yarn add webpackbar

# pnpm
pnpm install webpackbar

# bun
bun install webpackbar

# deno
deno install webpackbar

Then add the reporter as a plugin to your webpack config (make sure webpack peer dependency is installed).

webpack.config.mjs

import WebpackBar from "webpackbar";

export default {
  entry: "./src/entry.js",
  plugins: [
    new WebpackBar({
      /* options */
    }),
  ],
};

For using with Rspack, you can use webpackbar/rspack (make sure @rspack/core peer dependency is installed).

rspack.config.mjs:

import WebpackBar from "webpackbar/rspack";

export default {
  entry: "./src/entry.js",
  plugins: [
    new WebpackBar({
      /* options */
    }),
  ],
};

name

reporters

Register an Array of your custom reporters. (Same as reporter but array)

Webpackbar comes with a fancy progress-bar out of the box. But you may want to show progress somewhere else or provide your own.

For this purpose, you can provide one or more extra reporters using reporter and reporters options.

NOTE: If you plan to provide your own reporter, don't forget to setting fancy and basic options to false to prevent conflicts.

A reporter should be instance of a class or plain object and functions for special hooks. It is not necessary to implement all functions, webpackbar only calls those that exists.

Simple logger:

const logger = {
  start(context) {
    // Called when (re)compile is started
  },
  change(context) {
    // Called when a file changed on watch mode
  },
  update(context) {
    // Called after each progress update
  },
  done(context) {
    // Called when compile finished
  },
  progress(context) {
    // Called when build progress updated
  },
  allDone(context) {
    // Called when _all_ compiles finished
  },
  beforeAllDone(context) {},
  afterAllDone(context) {},
};

context is the reference to the plugin. You can use context.state to access status.

Schema of context.state:

{
  start, progress, message, details, request, hasErrors;
}
