The project code is impressive, but it lacks documentation, which can make it difficult to figure out how to configure. To start the project, navigate to the /app directory and use the command 'yarn dev.' Next, open another terminal and go to the /socket directory. From there, use the commands 'npm install' and 'npm start.'

It's important to note that the socket expects to see the app running on port 3000, as specified in the code at /monkeytype-clone/socket/build/index.js.
exports.io = new socket_io_1.Server(server, { cors: { origin: [ "http://localhost:3000", "https://mtype.vercel.app", "https://monkeytype-clone.vercel.app", "https://typez.vercel.app", ], methods: ["GET", "POST"], }, });

Additionally, the code at /monkeytype-clone/app/src/node_modules/next/dist/compiled/regenerator-runtime/runtime.js includes the line 'const API_URL = process.env.NEXT_PUBLIC_API_URL;' dont touch anything !

To configure the project, create a .env variable on the /app dir with the command 'nano .env'( i am using nano editor) and include the following line: 'NEXT_PUBLIC_API_URL=http://localhost:8080/graphql.'

Although the project code is impressive, it's crucial to have clear and comprehensive documentation to help users understand how to set it up and use it. I recommend updating the documentation to provide clear instructions on how to configure the project, including all dependencies and configurations required for successful operation.
