What is Laravel Mix?
Why Interviewers Ask This
Interviewers use this question to quickly assess whether a candidate has the foundational knowledge required for Laravel development. It reveals whether you understand the building blocks that more complex concepts rely on.
Answer
Laravel Mix is a wrapper around Webpack that provides a fluent API for defining asset compilation — compiling SASS/Less to CSS, bundling JavaScript, versioning assets. Configured in webpack.mix.js. Example: mix.js("resources/js/app.js", "public/js").sass("resources/sass/app.scss", "public/css").version(). Run: npm run dev (development) or npm run prod (production, with minification). Mix has been largely replaced by Vite (the default since Laravel 9) — which is significantly faster (no bundling during development, uses native ES modules) and configured in vite.config.js. The @vite Blade directive includes compiled assets. Vite provides instant hot module replacement (HMR) during development.
