Back to front - Backend technologies for the frontend developer
summary
Covers practical backend techniques front-end engineers can use: HTTP cache headers and stale-if-error (implemented at ASOS to serve expired images on network failure), ETag-based refresh to avoid re-downloading resources and detect mid-air edits, server-side rendered search pages cached ~10 minutes to cut origin load, OAuth/JWT flows with refresh-token edge cases, idempotency via UUID tokens so retried purchases don’t charge twice, and deployment tooling: Docker/Containerd, Kubernetes, CDNs, load balancers, multi-region clusters and Chaos Monkey resilience testing.
