GQLClientGen is a Golang client generator for GraphQL APIs. It automatically generates Golang clients for GraphQL services, which can be used for interacting with GraphQL APIs in a simple and efficient way.
For the actual GQL Client check this repo gqlclient.
Run the following command to install gqlclientgen.
go install github.com/stefanprifti/gqlclientgen/cmd/gqlclientgen@latest
In order to use the generator, the project must declare a configuration file named gqlclientgen.yml. Here is a sample project.
Sample config:
version: 1
services:
- name: Countries API
package: countries
url: https://countries.trevorblades.com/graphql
operations:
root: gql/countries
client:
root: pkg/countries
The version field specifies the version of the config file.
The services field is a list of the GraphQL services that the generator will process. Each service has a unique name and package name. The url field is the GraphQL endpoint that the generator will use to retrieve the GraphQL schema. The operations field is the path to the directory containing the GraphQL queries that will be used to generate the client. The client field is the path to the directory where the generated client code will be stored.
Once the config file is created, the generator can be run using the gqlclientgen command. This will generate the Golang client code for the specified GraphQL services.
Based on this configuration the generator will create this package.
client.go: This file contains the code of the generated client. It defines queries and mutations as methods of the client.model.go: This file contains the GoLang equivlent types of GraphQL schema.schema.graphql: This file contains the GraphQL schema of the API. It defines the types, fields, and operations that are exposed to the client via the GraphQL API.schema.introspect.json: This file contains the introspection query result for the GraphQL schema. It can be used to generate client-side code for the GraphQL API.
The generated package can be imported and used in any GoLang application.
