learn-gqlgen

My history about the process to learn GraphQL+Go

Maybe the roadmap will be:

• Setup gqlgen
  • Setup the graphql server
• Code slightly more realistic
  • Complete the example from "getting started" documentation
• Custom example (may the force be with you)
  • Create a custom types and resolvers, with the Starwars example
• Handling errors
  • Make more robust our code, handling errors
• Apollo Federation
  • Create more graphql servers, and connect between that
• Connect with a persistent layer
  • Now add a database server to save the data

Step 1. Setup gqlgen

Do next, with the current code, and it will run like the example from https://gqlgen.com/getting-started/.

$ mkdir learn-gqlgen
$ cd learn-gqlgen/
$ go mod init github.com/eisenheimjelid/learn-gqlgen
$ go get github.com/99designs/gqlgen
$ go run github.com/99designs/gqlgen init
Exec "go run ./server.go" to start GraphQL server
$ go run server.go 
2021/03/02 16:29:48 connect to http://localhost:8080/ for GraphQL playground

Step 2. Add code slightly more realistic

Add new graph/model/todo.go, regenerate the code and implement the new resolver into graph/schema.resolvers.go.

$ go generate
$ go run server.go 
2021/03/02 20:35:39 connect to http://localhost:8080/ for GraphQL playground
