GraphQL#

GraphQL is a language for describing the structure of data to be returned in an API.

Note

This generator will only create GraphQL definitions, it will not create runtime bindings.

Example Output#

personinfo.graphql

Overview#

Graphql can be generated from a LinkML schema.

To run:

gen-graphql personinfo.yaml > personinfo.graphql

Inheritance#

type Person implements HasAliases
  {
    id: String!
    name: String
    description: String
    image: String
    primaryEmail: String
    birthDate: String
    ageInYears: Integer
    gender: GenderType
    currentAddress: Address
    hasEmploymentHistory: [EmploymentEvent]
    hasFamilialRelationships: [FamilialRelationship]
    hasMedicalHistory: [MedicalEvent]
