This piece is part of a series. It’s not suited to beginners but you can check it out from the start with part 1

You can review how to get up to this part.

As always, the code is in GitHub.

Today we’ll add GORM and a database to our project. The RDBMS of my choice is PostgreSQL. You can use MySQL, SQLite, whichever you like as long as GORM supports it.

And, you can also check out part 2, in case you’ve missed it. …

In this piece, we’ll add gqlgen’s generated server into our project and start gqling away! And, we are going to move much faster than in part 1.

Adding gqlgen Into the Project

Now, we can use gqlgen to initialize our server’s gqlgen generated files: go run github.com/99designs/gqlgen init

This will initialize the gqlgen server. We have to make modifications to fit our project layout, however. Move a couple of files and edit the gqlgen.yml file.

• generated.go (file that holds the gqlgen's generated GraphQL server code.)
• resolver.go (holds the resolvers for the queries and mutations.)
• schema.graphql (example schema that gqlgen generates, we'll modify this.)
• server/server.go (stub…

Let’s make an opinionated GraphQL server using the Gin-gonic web framework, Goth for OAuth2 connections, GORM as DB ORM, and GQLGen for building GraphQL servers.

This project assumes you have at least basic Go knowledge, Go 1.12+ installed, and VSCode (preferred) or similar IDE.

Project Setup

We’ll follow the Go standard project layout for this service. Take a look at the specification. It is opinionated and serves as a good base, though we might stray a little bit from its guidelines.

Start by creating a directory anywhere we want to:

Let’s create the whole project layout with:

internal/gql-server will hold…
