Notes from the maintainer:
I started this project when I was still new to TS and full-stack development. Bad practices, confusing patterns, and messed up types are everywhere. Suggestions for improvements are very much welcome!
The client is currently being rewritten at the
frontend-refactorbranch (#24). Contributions tomainthat involve the frontend may get overwritten, but I'll try to cherry-pick those that can be applied to the new branch.

Development
Node.js 18 or newer is recommended.

client- Next.js application for the front-end, deployed to ches.su via Vercel.server- Node/Express.js application for the back-end, deployed to server.ches.su via Railway.types- Shared type definitions required by the client and server.

- Install the necessary dependencies by running
pnpm installin the root directory of the project. - In the
serverdirectory, create a.envfile for your PostgreSQL database. You can try ElephantSQL or Aiven for a free hosted database.PGHOST=db.example.com PGUSER=exampleuser PGPASSWORD=examplepassword PGDATABASE=chessu - Run the development servers with
pnpm dev.- To run the frontend and backend servers separately, use
pnpm dev:clientandpnpm dev:server, respectively.
- To run the frontend and backend servers separately, use
- You can now access the frontend at http://localhost:3000 and the backend at http://localhost:3001.
