Pre-deployment checklist.

Description

Pre-deployment checklist for your web app: auth/authorization so users only access what they’re supposed to, input validation and sanitization so bad data and attacks do not slip through, CORS so only approved origins can talk to your API, rate limiting so spam does not crush your backend, expiring password reset links so old emails cannot become account takeovers, frontend error handling so users see clean fallback states instead of crashes, database indexes so your key queries stay fast, logging so you can see what broke in production, alerts so you hear about issues before your users do, and rollback so one bad deploy does not turn into a full incident. Ofc there is more but that is a good place to start! #coding #programming #softwareengineer #systemdesign
