frontend-case-studies

Articles like “Building a simple todo list with [framework or technology name]” won’t teach you how that framework or technology solves real-world problems and works at a large scale. This document is a curated list of technical talks and articles about real-world enterprise frontend development.

[!IMPORTANT] As of January 2025, we've launched a website where you can browse case studies with a better UX! Please use the website for the latest updates. Entries in this README will no longer be updated and will eventually be removed completely.
