Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
How attackers turn a web app breach into euros — credential resale, payment data, account takeover, fraudulent transactions. The economics that drive defenses.
Who actually attacks web applications, what they're after, and the threat models that matter for SaaS, e-commerce, and B2B platforms in 2026.
Streaming makes AI features feel responsive instead of frozen. Here's the full pipeline — async views, SSE, JavaScript client, and the nginx tweaks that matter.
Embed documents, store vectors in Postgres, and let an LLM answer questions about your own data — without hallucinating its sources.
Build production RPA bots in Python: log into vendor portals, scrape dashboards, fill forms, and persist sessions — orchestrated from Django via Celery. The modern, license-free alternative to UiPath and Automation Anywhere.
HTMX brings SPA-feel interactions back to server-rendered Django: inline forms, live validation, infinite scroll, modals, and partial updates — all from regular Django views returning HTML fragments. The full pattern with CSRF and SSE.
A pragmatic Kubernetes setup for a real Django app: Deployment + Service + Ingress, ConfigMaps and Secrets done right, liveness/readiness probes that work, HPA on the right metric, and PgBouncer in front of PostgreSQL.
Three pillars — logs, metrics, traces — wired into a real Django app. Sentry for errors, structlog for context, django-prometheus for golden signals, OpenTelemetry for distributed traces. The minimum to debug prod without ssh-ing in.
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.
