Frontend for Backend Engineers

The Mental Model Shift

How backend engineers can rewire their thinking from request/response cycles to render trees and declarative UI.

Modern React in Five Concepts

Cut through the noise: components, props, state, effects, and hooks are all you need to read and write production React.

State, Properly

Local, server, and URL state are three distinct categories — pick the wrong one and you will fight your framework forever.

Forms Without Tears

Controlled vs uncontrolled inputs, validation strategies, and submitting to a server without reinventing the wheel.

Auth on the Client

Cookies vs tokens, refresh flows, and why 'store the JWT in localStorage' is the wrong answer.

Caching and Revalidation

How TanStack Query and SWR implement stale-while-revalidate, and how HTTP cache headers fit into the picture.

Streaming UIs and Suspense

How React 19 streaming, server components, and Suspense enable progressive rendering that backend engineers will recognize from HTTP chunked transfer.

Performance Triage

Read Web Vitals like a backend engineer reads p99 latency — then fix the right things with Lighthouse and bundle analysis.

Testing

Build a frontend test pyramid with Vitest, React Testing Library, and Playwright — and know what to mock versus what to leave real.

Deploying Static-First

Static export, edge functions, and CDN cache headers — deploy your React app the way backend engineers design for scale: as close to the user as possible.
