Frontend Articles — CodersSecret

Tutorials and deep dives into Angular, React, TypeScript, CSS, and modern frontend development.

• State Management Showdown: NgRx vs Signals vs Services in Angular — Angular has three state management approaches and choosing wrong means either over-engineering a todo app or under-engineering an enterprise dashboard. Compare NgRx, Signals, and plain services with real examples and a decision framework.
• Web Authentication API: Passwordless Login with Passkeys — Passwords are the weakest link in security. Passkeys replace them with biometrics and device-bound credentials. Learn WebAuthn, FIDO2, and how to implement passwordless login in your web app with real code examples.
• Micro-Frontends: Splitting a Monolith UI Without the Pain — Your frontend monolith has 200 components, 15 teams, and deploys take 45 minutes. Micro-frontends let teams ship independently. Learn Module Federation, shared dependencies, routing strategies, and when NOT to use them.
• CSS Grid and Flexbox Mastery: Stop Guessing, Start Designing — Flexbox is for one-dimensional flow. Grid is for two-dimensional layout. Learn when to use which, build responsive layouts without media queries, and master the patterns that replace 90% of CSS frameworks.
• Web Performance Secrets: Core Web Vitals from Red to Green — Your Lighthouse score is red. Users are bouncing. Google is penalizing your rankings. This guide fixes LCP, CLS, and INP with practical techniques — lazy loading, image optimization, font strategies, and real before-after audits.
• Angular Signals Deep Dive: Replacing RxJS the Right Way — Angular Signals are not a drop-in replacement for RxJS — they solve different problems. Learn when to use signals vs observables, migration patterns, computed/effect gotchas, and real refactoring examples in Angular 21.
• WebSocket vs SSE vs Long Polling: Building Real-Time Features the Right Way — Not every real-time feature needs WebSocket. Learn when to use Server-Sent Events, Long Polling, or WebSocket with practical Angular examples, scaling strategies, and a decision framework that saves you from over-engineering.
• Building Your Own Design System: The Complete Practical Guide — A no-nonsense, production-grade guide to building a design system from scratch. Covers design tokens, component architecture, documentation, versioning, and the mistakes that kill most design systems before they launch.
• Angular 21 in 2026: Why It Wins for Large-Scale Applications — A deep dive into Angular 21 — signals, standalone components, deferred views, and why Angular dominates enterprise-scale apps. Compared head-to-head with React and Vue.
