# Webpack Pro
A practical guide to webpack for the teams that still run it (which is many): loaders and plugins, code splitting, long-term caching, Module Federation, and build-performance tuning — plus knowing when to migrate away.
## Overview
webpack bundles everything through a graph of **loaders** (transform files: TS→JS, SCSS→CSS, images→URLs) and **plugins** (bundle-level work: HTML generation, env injection, minification). Its power is configurability; its cost is complexity and build speed. Modern practice: keep configs minimal, lean on defaults, and only reach for webpack-specific features (Module Federation, deep customization) when they earn their keep.
## When to use
- Maintaining existing webpack builds (Create React App ejections, legacy apps).
- Module Federation for micro-frontends.
- Highly custom build pipelines (custom loaders/plugins).
- Build performance triage on slow webpack setups.
