Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
How to ship schema changes without locking your production database. NOT NULL adds, column renames, index creation, and the multi-deploy patterns that separate Django teams who break prod from those who don't.
Stop hand-rolling token auth. Production-grade JWT for Django REST Framework: access/refresh tokens with rotation, blacklist-on-logout, secure storage (httpOnly cookies vs localStorage), and OAuth2 social auth with allauth.
Move beyond "int and str" type hints. Master TypeVar generics, structural typing with Protocol, TypedDict for JSON, mypy strict mode, and runtime validation with pydantic v2 — what production codebases actually use.
A pragmatic guide to caching in Django: choose the right level (site, view, fragment, low-level), avoid the stampede, and solve the only hard problem — invalidation — with versioned keys and signal-driven busts.
Move slow work off the request/response cycle. Architect Celery + Redis for production: workers, queues, retries with exponential backoff, periodic jobs with Beat, and live monitoring with Flower.
Advanced patterns for signals and middleware. Learn when signals cause more pain than value, how to write thread-safe middleware, audit logging, request tracing, and debugging production issues.
Practical, Django-specific defenses against the OWASP Top 10. Real attack examples and the exact code, settings, and tools you need to prevent them in production.
Build a complete CI/CD pipeline: automated tests, linting, security scans, Docker builds, and zero-downtime deploys. Reusable workflows, matrix builds, and deployment strategies.
Push your Django app beyond basic queries. Master B-tree vs GIN indexes, JSONB for semi-structured data, full-text search with ranking, and window functions for analytics.
Build lean, secure, production-ready Django Docker images. Multi-stage builds, dependency caching, non-root users, compiled static files, and health checks that shrink images from 1.2GB to 150MB.
Build a production-ready real-time Django app. Covers Channels architecture, WebSocket consumers, group messaging, authentication, Redis channel layer, and deployment with Daphne + nginx.
Master async programming in Python. Learn event loops, coroutines, tasks, aiohttp for concurrent HTTP requests, and when async actually makes sense vs. threads or multiprocessing.
