README.md:

Configuration

This project is structured as a monorepo using npm workspaces, separated into three packages:

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

Scripts

# install all dependencies, including eslint and prettier for development npm install # concurrently run frontend and backend development servers npm run dev # -w client/server to run only one # for separate production deployments npm install -w client npm install -w server npm run build -w client npm run build -w server npm start -w client npm start -w server

For separate deployments, you may exclude the client or server directory. However, you should include the types folder as it contains shared type definitions that are required by both packages.

Environment variables

You may create a .env file in each package directory to set their environment variables.

NEXT_PUBLIC_API_URL=http://localhost:3001 # replace with backend URL

server:
