How I write Angular apps in 2025: Tools, Tips, Techniques

In this relatively short video, I cover the tools and techniques I’d use if I were starting an Angular application in 2025. From state management to testing tools and modern Angular features, I’ll share my personal approach to building scalable and maintainable apps.

Here’s what I’ll discuss:

🚦 The Role of Signals: Should we go all-in or stick with RxJS and wait?

🔮 The Future of zone.js: What’s its role in 2025?

⚙️ Angular CLI vs. Nx: Which one should you choose and when?

🎨 UI Tools: Tailwind CSS, Angular Material, and more.

🧪 Testing Tools: Jasmine or Jest? Cypress or Playwright?

🛠️ Code Guidelines & Quality: ESLint and Prettier—are they enough?

🗂️ Modern State Management: When to use it and why NgRx SignalStore is my choice.

🔄 Dependency Injection: Inject vs. constructor-based—what’s better?

🌐 SSR & Hydration: Is the hype justified?

🤖 Miscellaneous Topics: Tools like pnpm, AI assistants, and more.
