esbuild is a JavaScript bundler written in Go that supports blazing-fast ESNext & TypeScript transpilation and JS modification. esbuild-loader lets you harness the speed of esbuild in your Webpack build by offering faster alternatives for transpilation (eg. babel-loader/ts-loader) and minification (eg. Terser)! If you have a tsconfig.json file, esbuild-loader will automatically detect it. esbuild only supports a subset of tsconfig options (see TransformOptions interface) and does not do type-checks. It's recommended to use a type-aware IDE or tsc --noEmit for type-checking instead. It is also recommended to enable isolatedModules and esModuleInterop options in your tsconfig by the esbuild docs. You can replace JS minifiers like Terser or UglifyJs. Checkout the benchmarks to see how much faster esbuild is. The target option tells esbuild that it can use newer JS syntax to perform better minification.
Features
- Javascript & JSX transpilation
- Use the minify plugin in-place of the loader to transpile the JS
- There are two ways to minify CSS, depending on your setup
- If your CSS is extracted and emitted as a CSS file, you can replace CSS minification plugins
- If your CSS is not emitted as a CSS file, but rather loaded via JS using something like style-loader, you can use the loader for minification
- esbuild-loader comes with a version of esbuild it has been tested to work with
