Durable Web Workers: From One-Off Scripts to Robust Off‑Main‑Thread Systems
A practical guide to designing Worker-based systems that don’t jank, leak, or stall. Start with a baseline, add timeouts and cancellation, coalesce requests, and use a bounded pool when parallelism actually helps.
Structured Clone vs JSON.stringify: Choosing the Right Tool for Cloning and Passing Data
JSON is convenient but lossy; structured cloning preserves complex graphs and enables zero‑copy transfers. Learn a mental model, decision rules, and a step‑by‑step path from quick JSON hacks to robust, measurable solutions.
Show Your Custom Domain on Google OAuth with Firebase
Replace the default Firebase domain on the Google account chooser with your own (e.g., auth.yourdomain.com) by adding a dedicated Hosting site, verifying the domain, and updating OAuth origins/redirects.
Fixing Firebase DNS on Namecheap: Remove the Domain From Host
Firebase shows fully‑qualified names for DKIM/SPF records. In Namecheap, you must not include your domain in the Host field—only the sub‑label (e.g. 'app' or 'firebase1._domainkey.app').
