simple_static_graphql_api

Overview

Simple test application for GraphQL API in Go

Quickstart

Follow the instructions in docs/pact_testing.md to setup the Pact tools.

Development Notes

Details of how this project was created. You don't need to follow these instructions to get things up and running

Setup

• Created initial module file

go mod init github.com/fionahiklas/simple-static-graphql-api

• Adding dependency

go get github.com/graph-gophers/graphql-go

• Created basic Makefile to be able to run tests and linting

Resolvers

• For string fields which can be nullable (don't have !) the type is *string rather than string
• To set pointer to empty string as a return value needs some work as per this post
• It seems that [SomeGraphQLType!]! requires a Go slice so *[]*SomeGoStruct doesn't seem to be correct
• Unless you allow struct resolvers (this is mentioned in the docs, TODO: add link) each resolver needs to implement accessors for every field in the GraphQL type
