Project mention: Resume Scan AI app built with Next.js 15, Tailwind CSS, BetterAuth, Open AI, Inngest, and Shadcn/ui | dev.to | 2025-06-17
Next.js
-
The final RN 0.80 version comes with fresh React 19.1.0 (0e11e6a28b)! This brings improvements like "owner stacks" to help identify which component caused a specific error (although there's a known bug if you use the @babel/plugin-transform-function-name plugin).
-
This project was bootstrapped with Create React App.
-
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.

Docusaurus is a powerful static site generator built by Meta and designed specifically for documentation websites. It’s React-based, which means you get a lot of flexibility in how you customize your site, and it comes with features that make API documentation much easier to manage:
-
Static websites are so good that they even have their own three-letter abbreviation: SSG (Static Site Generation). And of course, there are plenty of frameworks that generate them for you, no need in manual labour: Next.js supports SSG, Gatsby is still pretty popular, lots of people love Docusaurus, Astro promises the best performance, and probably many more.
