Apollo Server Typescript Subgraph Template

This template can be used to quickly create an Apollo Federation subgraph with the @apollo/subgraph and @apollo/server packages. You can use this template from Rover with rover template use --template subgraph-typescript-apollo-server.

What's Included

• A basic, Apollo Federation subgraph with simple examples for queries, entities, and mutations. You can run this subgraph with npm start.
• nodemon is setup for npm run dev for a hot-reloading development environment.
• Example tests in the src/__tests__ directory. You can run these tests with npm run test.
• GitHub Actions workflows which will:
  • Run npm run test on every push.
  • Check the schema against Apollo Studio on every push.
  • Publish the subgraph to Apollo Studio on every push to the main branch.
• GraphQL Code Generator pre-configured as a build step.

Next Steps

• Setup project with npm install
  • This will also run the postinstall script which will run codegen and compile the project
• Download Rover and start it using the command printed out from cargo run to start a local version of Apollo Explorer.
• Replace "name" in package.json with the name of your subgraph.
• Start filling in your own schema in schema.graphql.
• Start filling in your own types and resolvers in src/resolvers.
• Set these secrets in GitHub Actions to enable all checks:
  • APOLLO_KEY: An Apollo Studio API key for the supergraph to enable schema checks and publishing of the subgraph.
  • APOLLO_GRAPH_REF: The name of the supergraph in Apollo Studio.
  • PRODUCTION_URL: The URL of the deployed subgraph that the supergraph gateway will route to.
• Remove the if: false lines from .github/workflows/checks.yaml and .github/workflows/deploy.yaml to enable schema checks and publishing.
• Write your custom deploy logic in .github/workflows/deploy.yaml.
• Send the Router-Authorization header from your Cloud router and set the ROUTER_SECRET environment variable wherever you deploy this to.
