Build Profiler

Getting Started

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 */
    }),
  ],
};

Options

name

• Default: webpack

Name.

color

• Default: green

Primary color (can be HEX like #xxyyzz or a web color like green).

profile

• Default: false

Enable profiler.

fancy

• Default: true when not in CI or testing mode.

Enable bars reporter.

basic

• Default: true when running in minimal environments.

Enable a simple log reporter (only start and end).

reporter

Register a custom reporter.

reporters

• Default: []

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

Custom Reporters

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;
}
