GraphQL Tutorial
This is a didactic introduction to GraphQL, starting from a simple Hello
World to a network-based GraphQL server with a built-in GraphQL UI.
It is provided in the form of a tutorial which step-by-step
introduces more usage of GraphQL. Each tutorial step XX can be found
in the file sample-XX and run with npm run sample-XX. The
distinct tutorial steps are:
- just plain all-in-one GraphQL "Hello World"
- replaces GraphQL schema API calls with GraphQL schema definition language
- split GraphQL usage into distinct parts
- replace "Hello World" with an entity "OrgUnit" and enable schema/resolver warnings
- add "Person" entity and use a separate data store
- factor out resolver functionality into generic data access object functions
- add QueryEntityOne DAO method for querying particular objects
- allow relationships to be queried and be strict on resolvers now
- add remaining CRUD operations (create/clone, update, delete) to GraphQL entity types
- wrap GraphQL application programming interface (API) with a remote network interface (RNI)
- replace built-in client with interactive GraphQL web user interface (GraphiQL)
- add descriptions to GraphQL schema for introspection inside GraphiQL
- move data into SQLite RDBMS and access it with Sequelize ORM
- wrap mutations into a single RDBMS transaction
- support also GraphQL over Websocket communication
- add GraphQL Subscription support
- simplify and migrate to all-in-one GraphQL-IO framework
