During a recent discussion with some colleagues about TypeScript decorators, we ended up deep-diving into Angular.dev and stumbled upon something interesting — the @Attribute decorator.
-
Material UI
Ready-to-use foundational React components, free forever. It includes Material UI, which implements Google's Material Design.
MUI is the OG of UI component libraries. They’ve been at the top back since when Bootstrap was a contender and are still maintaining a top spot in the era of Tailwind and other UI libraries. With more than 95k GitHub stars (and counting), and top companies using it in production, I’d say this is the open-source React component library with the most stars. MUI also has paid components available for enterprise users.

Nest

NestJS brings that same level of organization and scalability to the TypeScript ecosystem, something often undervalued when choosing a backend framework.

Project mention: How to use Angular 20 experimental Vitest support outside of ng test | dev.to | 2025-06-18
So, I had to test this new version in a personal project to learn how to use all these new things along with other technologies and tools I’ve used for a long time and also love, like VSCode, ESLint, Prettier, and a bunch of other. And I did, but there’s a catch which makes the whole “experimental” thing have more sense: you can only use this through ng test.

Project mention: TypeScript's progressive adoption strategy for front-end projects | dev.to | 2024-12-03
Sometimes, the community will provide unofficial type definitions. You can find it in the DefinitelyTyped repository (https://github.com/DefinitelyTyped/DefinitelyTyped), or search for @types/library-name on GitHub.
