GraphQL implementation example with Go
To understand how GraphQL works, we create a simple GraphQL application with the Go programming language. The GraphQL application is created with the gqlgen library. This library has many features, including generating a resolver from the schema.
You may use the following commands to initialize the project if you have to set it up on a local machine. However, it has already been set up for you on the Educative platform.
go mod init go-simple-graphql
Add the gqlgen library with this command. The version we’re using is 0.17.10.
go get github.com/99designs/gqlgen@v0.17.10
Next, create a project skeleton using the gqlgen library with this command.
go run github.com/99designs/gqlgen init
In the project, there’s a file called schema.graphqls in the graph directory. ...
