Learn how to use Babel's preset-env to include only the transforms needed for your target browsers and Node versions, reducing bundle size while keeping builds reproducible.
Learn how to use Grunt to reduce HTTP overhead by concatenating and minifying JavaScript assets using grunt-contrib-concat and grunt-contrib-uglify.
Stop duplicating helper functions in your JS bundles. Learn how @babel/plugin-transform-runtime reduces bundle size and prevents global namespace pollution for libraries.
A diagnostic guide to Webpack 'Module not found' errors: read the resolver probe list, then fix extensions, aliases, file case or module roots.
Learn how PostCSS’s nesting plugin rewrites hierarchical CSS into flat browser‑ready rules, the pitfalls of deep nesting, and a step‑by‑step example that shows how to set up a build pipeline and test the output.
Legacy Gruntfiles are usually 80% duplication. Multitask targets, hierarchical options merging, and <%= %> templates fix that — if you know about the array-replacement trap.
Precompiling Handlebars templates moves parsing out of the browser and shrinks your bundle to the runtime only. Here's how it works, a CLI example, and the version-skew trap to avoid.
Grunt's declarative Gruntfile still solves real asset-pipeline problems cheaply. A worked concat/uglify/watch example, honest I/O trade-offs, and a keep-or-migrate decision framework.
PostCSS transforms nothing by itself — the real decision is which plugins run and in what order. Compare postcss-preset-env against hand-picked plugins, write a custom plugin with the current API, and validate the pipeline in a unit test.
