This a template for an GraphQL API in Golang with

• Gin Server: Fast server
• Graphql-Go (Gophers): GraphQL Engine
• Gorm: ORM in GO (connected with postgreSQL)
• GraphiQL: GraphQL web client
• SQL-Migrate: DB migrations
• Dep: Go dependecy manager

Install

You can install asdf if you are in linux or MacOS, this allow you to have several dev envs including GOLANG

1. Config go path and bin

Add in your ~/.bashrc or ~/.zshrc

export GOPATH=$HOME/go
export PATH="$PATH:$GOPATH/bin"

APP Folder

This project should be at $GOPATH/src it means ~/go/src

And the name should be test_articles, please rename it!

So the final code should be at ~/go/src/test_articles

---

Now, you have to install some commands (2. ,3. ,4.)

2. Gin (Server with hot-reload)

go get github.com/codegangsta/gin

3. SQL-Migrate (for migrations)

go get -v github.com/rubenv/sql-migrate/...

4. Dep (Dependecy manager)

go get -u github.com/golang/dep/cmd/dep

---

5. Copy .env file

cp .env-example .env

And change your configuration values

Initial Run (preparing database)

1. Get depencies

dep ensure

2. Run initial migrations

export `egrep -v "#" .env | xargs -0`
sql-migrate up -config="config/sql-migrate.yml"

3. Run seeds

go run db/seeds/adding_articles.go

Regular Run

Start the server

gin

The API should be at http://localhost:3000/graphql

Migrations

Run this at least once in your console

export `egrep -v "#" .env | xargs -0`
