Contributing

I would love to see your contribution. ❤️

For local development (and testing), all you have to do is to run yarn and then run server yarn start:server and client yarn start:client. That will start the Apollo server with client and you are ready to contribute 🎉

Run yarn test (try --watch flag) for unit tests (we are using Jest)

TODO:

• Add types
• Support for computing nested fields
