Build Profiler

Getting Started

To begin, you'll need to install webpackbar:

Using npm:

npm install webpackbar -D

Using yarn:

yarn add webpackbar -D

Then add the reporter as a plugin to your webpack config.

webpack.config.js

const webpack = require("webpack");
const WebpackBar = require("webpackbar");

module.exports = {
  context: path.resolve(__dirname),
  devtool: "source-map",
  entry: "./entry.js",
  output: {
    filename: "./output.js",
    path: path.resolve(__dirname),
  },
  plugins: [new WebpackBar()],
};

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:

{
 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;
}
