go install github.com/Applifier/graphql-codegen

TODO

• Allow custom templates (without rebuilding)

example

Example below generates code for schema.graphql. Optional config config.hcl file is provided to tell the codegen where and how to fetch the data for the resolvers.

graphql-codegen generate -s=codegen/fixtures/httpget/schema.graphql -c=codegen/fixtures/httpget/config.hcl -p=httpget -o=test_output/

Example of the generated code (_gen.go files) can be found under /codegen/fixtures/httpget

• More examples under codegen/fixtures

templates

default

Resolve field based on a struct property with the same name as the schema type field

custom

Skips code generation for the field

Check example config and conversation.go

http_resolver

Resolve field with a http GET request to a server

type "Query" {
  field "user" {
    imports = ["\"fmt\""]
    template "http_resolver" {
      url = "fmt.Sprintf(\"https://static.everyplay.com/developer-quiz/data/users/%s\", args.ID)"
    }
  }
}
