webpack-format-messages

Beautiful formatting for Webpack messages; ported from Create React App!

The console output from CRA is very well-done! Unfortunately, the only way to use it is to install all of react-dev-utils, which is quite a module-rich tree. While there is nothing wrong with this, many times I'd prefer a quick install for my custom Webpack configs (which aren't always React-related).

If you are already using react-dev-utils, you do not need this module and should do this instead:

const formatMessages = require('react-dev-utils/formatWebpackMessages');

Differences

The source code of this module is (nearly) a direct copy-paste of the original file. Only two modifications have been made:

  1. The code has been tailored to run in a Node-specific environment --- the original can also be run in the browser.
  2. The module input expects a Webpack stats object --- the original required a toJson() transformation

Install

$ npm install webpack-format-messages --save-dev

Usage

const webpack = require('webpack');
const formatMessages = require('webpack-format-messages');
 
const compiler = webpack(/* config */);
 
compiler.plugin('invalid', () => console.log('Compiling...'));
 
compiler.plugin('done', stats => {
  const messages = formatMessages(stats);
 
  if (!messages.errors.length && !messages.warnings.length) {
    console.log('Compiled successfully!');
  }
 
  if (messages.errors.length) {
    console.log('Failed to compile.');
    messages.errors.forEach(e => console.log(e));
    return;
  }
 
  if (messages.warnings.length) {
    console.log('Compiled with warnings.');
    messages.warnings.forEach(w => console.log(w));
  }
});
