Training program

Module 1Rollup Fundamentals: CLI configuration and rollup.config.js (CJS/ESM formats, first bundles)

Quick Rollup installation via npm, creation of a test project to bundle modern JS modules, exploration of the rollup.config.js file with exercises on CJS and ESM output formats, first practical builds on real enterprise code, analysis of generated bundles with tools like source-map-explorer, resolution of common errors and basic input optimization, deliverable: a functional production-ready bundle with documentation.

Module 2Essential Rollup Plugins: Babel, Terser, and polyfills integration (tools, chaining, real cases)

Discovery of key plugins like @rollup/plugin-babel for ESNext transpilation, @rollup/plugin-terser for aggressive minification, exercises chaining plugins in Rollup config, adaptation to enterprise projects with smart polyfills, tests on personal libraries, performance gains measurement via Lighthouse, creation of an automated watch-mode workflow for iterative development, production of an ultra-light minified bundle with detailed optimization report.

Module 3Advanced Rollup Optimizations: tree-shaking, code splitting, and dynamic imports (methods, performance)

Deep dive into Rollup's native tree-shaking to eliminate dead code, code splitting configuration with dynamic imports for scalable apps, practical workshops refactoring legacy code to optimized modules, use of @rollup/plugin-node-resolve for external dependencies, before/after benchmarks on load times, sourcemaps integration for production debugging, development of a single-page app bundled into smart chunks, deliverable: red thread project with 40% improved performance metrics.

Module 4Rollup in Production: CI/CD, deployments, and custom plugins (GitHub Actions, servers, scalability)

Building CI/CD pipelines with Rollup in GitHub Actions and Jenkins, creation of custom Rollup plugins for specific enterprise needs, deployment to Vercel/Netlify with automated previews, multi-target browser management via plugins, exercises on hybrid library/app environments, collective code review and scalability best practices, finalization of live-deployed red thread project, delivery of skills certificate with ready-to-use optimized bundles portfolio.
