Chi phí khởi động service worker, cái bẫy fetch handler rỗng làm chậm mọi request, ngân sách precache, gộp request trùng (coalescing), tận dụng asset immutable, và bộ công cụ đo lường SW trong DevTools.
Hướng dẫn Proxyman từ cơ bản đến pro: capture & decrypt HTTPS, filter nâng cao, Compose/Repeat, Breakpoint sửa request/response on the fly, Map Local/Remote, Scripting JS, throttling, mobile, và workflow thực chiến.
Tie it together: a complete real-world config (SPA + API proxy + cache + TLS), reusable includes, Docker & Compose deploy, worker tuning, a debugging cheat-sheet for the errors you will actually hit, and a capstone project.
Cấu trúc debug với AI: reproduce trước, hypothesis sau, fix cuối. Kỹ thuật minimal repro, git bisect với AI, stacktrace decoding, heisenbug hunting, và lý do vì sao AI thường fix sai khi bạn chưa verify cause.
How V8 garbage collection works, why leaks are reachability bugs, classic frontend leak patterns, WeakRef tradeoffs, and a DevTools hunting workflow.
Senior deep-dive: Error object anatomy, what try/catch cannot catch, custom errors with cause, async patterns, global handlers, retries, and monitoring.
Make a k8s app production-shaped and learn to debug it: ConfigMaps & Secrets, liveness/readiness probes, resource limits, rolling updates and scaling, then a kubectl debugging playbook for CrashLoopBackOff, ImagePullBackOff and more.
The debugging playbook: read logs, exec in, inspect, events and stats — then a field guide to the errors you will actually hit (port in use, exit codes, OOMKilled, ImagePullBackOff, cache, networking) and how to resolve each.
A bilingual deep-dive into source maps: what they are, how they work internally (VLQ encoding, mappings field), how to generate and configure them, and best practices for production debugging.
