This project should work with all recent node versions, if you want to be sure you can use nvm and run nvm use to get the version we used to prepare the assignment. (or just install node v16.9.1 if you prefer)
Then run:
yarn
And you are ready!
Run the bff (backend for frontend) - apollo server:
yarn workspace @neulabs/bff dev
Then run the website (nextjs):
yarn workspace @neulabs/website dev
Don't worry about builds, serve or other commands, just make your work with these two commands only.
