Definition Defining your schema
Root Types Root types are the entry points for queries, mutations and subscriptions.
Generators Use Rails generators to install GraphQL and scaffold new types.
Introspection GraphQL has an introspection system that tells about the schema.
Lazy Execution Resolvers can return "unfinished" results that are deferred for batch resolution.
Parsing GraphQL Schema Definition Language into a Ruby Schema Defining a schema from a string or .graphql file
Dynamic types and fields Using different schema members for each request
Object Identification Working with unique global IDs
Executing Queries Evaluate GraphQL queries with your schema
Ahead-of-Time AST Analysis Check incoming query strings and reject them if they don't pass your checks
Phases of Execution The steps GraphQL takes to run your query
Complexity & Depth Limiting query depth and field selections
Timeout Cutting off GraphQL execution
Multiplex Run multiple queries concurrently
Lookahead Detecting child selections during field resolution
Tracing Observation hooks for execution
Backtrace Annotations Use the GraphQL backtrace for debugging
Logging Development output from GraphQL-Ruby
Response Extensions Adding "extensions" to the response hash
Instrumentation Wrap query execution with custom logic
Objects Objects expose data and link to other objects
Scalars Scalars are "simple" data types like integers and strings
Enums Enums are sets of discrete values
Input Objects Input objects are sets of key-value pairs which can be used as field arguments.
Interfaces Interfaces are lists of fields which objects may implement
Unions Unions are sets of types which may appear in the same place (but don't share fields).
Lists Ordered lists containing other types
Non-Null Types Values which must be present
Extending the GraphQL-Ruby Type Definition System Adding metadata and custom helpers to the DSL
Directives Special instructions for the GraphQL runtime
Field Extensions Programmatically modify field configuration and resolution
