Summary

In this chapter, we started implementing our backend application, which will be exposing the GraphQL API. We created a project using Lerna to follow the monorepo approach to organizing our code base, which will contain both the server and client apps.

We installed Express.js and configured it with TypeScript and also GraphQL via Apollo Server.

Next, we created an initial GraphQL schema for our small social network application and configured Apollo Server with mocking. Then, we used the casual tool to use realistic values for our mock data.

Thanks to mocking, we were able to run a working GraphQL server by providing only a schema without implementing the resolvers.

This is a great feature that allows us to easily test the GraphQL API without running a complete API server. It also allows the frontend developer/team to start working on the features that require data to be fetched from the server as quickly as possible without waiting for the backend development to...
