The profile cards fetch their ratings from the same-origin /api/ratings endpoint.
It is a Vercel serverless function that reads the public Codeforces, LeetCode,
AtCoder, and CodeChef profiles and returns one normalized response. The response
is revalidated on every visit and shared-cached by Vercel for 15 minutes to avoid
rate-limiting the profile platforms. npm run dev exposes the same endpoint
through Vite middleware, so the feature also works locally.
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel (or oxc when used in rolldown-vite) for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the TS template for information on how to integrate TypeScript and typescript-eslint in your project.
