suessflorian / gqlfetch

Generates a graphql server schema using introspection.

GQLFetch

GraphQL introspection based schema generator, introspection query document mirrors the graphql-js getIntrospectionQuery document albeit compliant to the June 2018 specification.

Usage

import (
	"github.com/suessflorian/gqlfetch"
)

func main() {
	schema, _ := gqlfetch.BuildClientSchema(ctx, endpoint)
}

Or use as cli tool

Introduced a directory here /gqlfetch which will create a gqlfetch cli tool.

go install github.com/suessflorian/gqlfetch/gqlfetch
# gqlfetch --help
gqlfetch --endpoint "localhost:8080/query" > schema.graphql

If you get an error claiming that gqlfetch cannot be found or is not defined, you may need to add ~/go/bin to your $PATH (MacOS/Linux), or %HOME%\go\bin (Windows).

Roadmap

Hoping to incorporate this into a graphql utility package like gqlparser, enable introspection based type-safe graphql client generation in genqlient and simplify the Service type federated services need to expose to a bramble gateway (improving the schema gathering logic).
