Apollo Rest API Server Adaptor Example

apollo-rest-example

Demo of wrapping a REST API Server via Apollo Server.

• Fully type safe
• Uses @graphql-codegen/typescript-resolvers to auto-generate the resolver types based on the Schema See graphql-server/codegen.yml for configuration

Start REST API Server

cd graphql-server
yarn start # or `yarn watch` for dev

Changes are only stored in memory, so all data is reset when restarting the server.

You can see all currently stored data via http://localhost:8080/books.

Start Apollo Server

cd graphql-server
yarn start # or `yarn watch` for dev
yarn graphql-generate # generate typings for resolvers based on schema

open http://localhost:4000/ to see the GraphQL Playground
