The modern Angular stack roadmap

Angular is a complete web application framework: component rendering, dependency injection, routing, forms, HTTP, build tooling, server rendering, testing, accessibility primitives, and an upgrade path.

Explain it like I am five

An Angular application is a tree of components. Each component owns a piece of the screen, receives inputs, emits events, reads state, and asks services for work. When tracked state changes, Angular updates the affected view.

Tailwind supplies small styling rules. Flowbite supplies styled interaction patterns. Neither replaces Angular's ownership of component state and lifecycle.

Current compatibility baseline, August 2026

Layer Current baseline Important constraint
Angular 22.1.x Actively supported
Angular CLI 22.1.x Keep framework and CLI majors aligned
Material / CDK 22.1.x Match Angular major
TypeScript 6.0.x Angular 22 requires >=6.0 <6.1
RxJS 7.8.x Angular supports compatible 7.x
Node.js 22.22+, 24.15+, or supported 26.x Use an Angular-supported line
Tailwind CSS 4.3.x CSS-first configuration and separate integrations
Flowbite 4.0.x Tailwind v4 themes and CSS variables
Unit tests Vitest Default for new CLI projects
Browser/E2E Playwright or equivalent Prove real browser behavior

“Latest” means the newest compatible set, not the highest version of every npm package. TypeScript 7 exists, but is outside Angular 22's supported range.

Architecture layers

browser → Angular router → feature shell → presentational components → application services/state → HTTP boundary → backend

Design tokens flow into Tailwind utilities and Flowbite themes. Accessibility, security, performance, testing, and observability cross every layer.

Learning loop

  1. Model one user outcome.
  2. Draw component and state ownership.
  3. Implement the smallest route and vertical slice.
  4. Test semantics and accessibility before visual polish.
  5. Measure bundles, rendering, network, and Core Web Vitals.
  6. Explain failure, loading, empty, and permission states.

Feynman check

Explain the difference between Angular, TypeScript, RxJS, Tailwind, Flowbite, Material/CDK, and the browser without calling any two of them “the frontend.”
