Frontend EngineeringEngineering decisions, not tutorials

Stop re-litigating frontend decisions from scratch. Find the trade-offs, choose deliberately, and ship the decision your future team can defend.

Trade-offs, stated honestly

Every article names what you give up, when the balance flips, and which alternative wins in each case — then makes a defensible recommendation.

Production code, not toys

Each pattern ships a naive version, a corrected version, and a production version with error handling, cancellation, and accessibility included.

A dependency graph, not a blog

Prerequisites, next steps, alternatives, and common mistakes are typed links between articles, validated in CI so the map never lies.

Framework-aware, not framework-bound

Concepts are owned once and cross-linked. Framework specifics are called out with versions where behavior depends on them.

Where to start

Working on data fetching or caching? Data & Server State is the most complete domain — request identity, staleness, mutations, pagination, and resilience.
Deciding where state should live? State Management starts with the classification that makes the rest of the decisions mechanical.
Chasing a performance problem? Performance Engineering covers the critical rendering path, Core Web Vitals, and code splitting.
Want the whole picture? The Knowledge Map lays out nine Parts and 35 domains; the Article Inventory lists every article with its status, difficulty, and prerequisites.

What this is not

Not a tutorial site, not a framework comparison scoreboard, and not a link dump. Articles are reviewed against the standards, carry explicit prerequisites, and are expected to stay useful for years — so anything that only makes sense inside one release cycle does not belong here.

Contributions are welcome: read CONTRIBUTING for the article template, the review criteria, and how the link graph is validated.
