v3.0.0

3.0.0 (2023-02-08)

Migration guide

• ESBuildMinifyPlugin was renamed to EsbuildPlugin to indicate it can be used as a general interface to esbuild (not just a minifier, but transformer).
  Import EsbuildPlugin instead:

- const { ESBuildMinifyPlugin } = require('esbuild-loader')
+ const { EsbuildPlugin } = require('esbuild-loader')

• For .js, .jsx, .ts, .tsx, .css files, you no longer need to set the loader option because esbuild-loader can now detect how to handle them based on the extension. This also means you can consolidate esbuild-loader rules for different file types into one, rather than hard-coding how to load each extension type.

 module: {
   rules: [
     {
       test: /\.[tj]sx?$/,
       loader: 'esbuild-loader',
       options: {
         target: 'es2015',
-        loader: 'tsx',
       },
     },
   ],
 },

👉 Note: For this to work, make sure to follow file extension conventions such as using .jsx/.tsx for files that contain JSX.

• You can now use the tsconfig property to pass in a tsconfig file, and it will even resolve extends

• tsconfig.json includes/excludes/files are now respected so it will only apply the tsconfig.json to matching files. However, TypeScript compilation will always work regardless of tsconfig.json.

• If Webpack's target is web, EsbuildPlugin will default to using format: iife unless otherwise specified. This change was made to prevent window pollution.

• Make sure your Node.js version is at least v16
