Apollo Server RESTDataSource Demo

This repository demonstrates how to use RESTDataSource in an Apollo Server v4 subgraph and make the data available via the Router.

Running the Example

• Start all the subgraphs in the /subgraphs directory
  • Install dependencies with npm install
  • Start the server and endpoints with npm start
  • Subgraph should be running at http://localhost:4001/{subgraph}/graphql
• Start Apollo Router in the /router directory
  • Download the router by running ./download_router.sh
  • Compose the schema by running ./create_local_schema.sh
  • Run the router by running ./start_router.sh
  • You can now open the Router at http://127.0.0.1:4000/ and start querying.
