graphql-compose

graphql-compose – provides a type registry with a bunch of methods for programmatic schema construction. It allows not only to extend types but also remove fields, interfaces, args. If you want to write your graphql schema generator – graphql-compose is a good instrument for you.

• provides methods for editing GraphQL output/input types (add/remove fields/args/interfaces)
• introduces Resolver's – the named graphql fieldConfigs, which can be used for finding, updating, removing records
• provides an easy way for creating relations between types via Resolver's
• provides converter from OutputType to InputType
• provides projection parser from AST
• provides GraphQL schema language for defining simple types
• adds additional types Date, Json

And a little bit more

graphql-compose-[plugin] – are declarative generators/plugins built on top of graphql-compose, which take some ORMs, schema definitions and create GraphQL Models from them or modify existing GraphQL Types.

Type generators built on top graphql-compose

• graphql-compose-json - generates GraphQL type from JSON (a good helper for wrapping REST APIs)
• graphql-compose-mongoose - generates GraphQL types from mongoose (MongoDB models) with Resolvers.
• graphql-compose-elasticsearch - generates GraphQL types from elastic mappings; ElasticSearch REST API proxy via GraphQL.
• graphql-compose-aws - expose AWS Cloud API via GraphQL

Utility plugins:

• graphql-compose-relay - reassemble GraphQL types with Relay specific things, like Node type and interface, globalId, clientMutationId.
• graphql-compose-connection - generates connection Resolver from findMany and count Resolvers.
• graphql-compose-dataloader - adds DataLoader to graphql-composer resolvers.
