GraphQL

The GraphQL layer that @packages/launchpad and @packages/app use to interact with @packages/server.

With the goal of type safety, several tools and abstractions are used. The technologies are:

• nexus-graphql library for generating GraphQL schema using TypeScript objects
• graphql-code-generator generate TypeScript types from gql queries (for front-end consuming the API)

This tutorial demonstrates how to build a type-safe GraphQL app using the above technologies. It's a good place to start, to learn how and why each tool is used.

Development

You will generally develop this in parallel with a front-end, in this case @packages/launchpad. Run yarn dev in @packages/launchpad and it will start up the GraphQL server. This also re-generates the graphql.schema file based on the declarations inside of entities.

Visit http://localhost:52200/graphql for the GraphiQL interface.

You can also develop in a test-driven manner using the tests.

• yarn test-unit for the unit tests
• yarn test-integration for the integration tests
