This example shows how to implement a GraphQL server with TypeScript based on Photon JS, graphql-yoga and GraphQL Nexus.

To run the example, you need the Prisma 2 CLI:

npm install -g prisma2

Install Node dependencies:

npm install

cp .env.example .env

Run the following command to generate Photon JS:

prisma2 generate

Now you can seed your database using the seed script from package.json:

npm run seed

Launch your GraphQL server with this command:

npm run start

Navigate to http://localhost:4000 in your browser to explore the API of your GraphQL server in a GraphQL Playground.

The schema that specifies the API operations of your GraphQL server is defined in ./src/schema.graphql. Below are a number of operations that you can send to the API using the GraphQL Playground.

Feel free to adjust any operation by adding or removing fields. The GraphQL Playground helps you with its auto-completion and query validation features.

To make changes to the GraphQL schema, you need to manipulate the Query and Mutation types that are defined in index.ts.

Note that the start script also starts a development server that automatically updates your schema every time you save a file. This way, the auto-generated GraphQL schema updates whenever you make changes in to the Query or Mutation types inside your TypeScript code.
