Lancey GraphQL POC

Concept

Implementing this architecture :

Install

First things first :

• Elixir/Erlang
• After installing Elixir, you need to install hex : $ mix local.hex
• Overmind (Process manager for Procfile-based applications and tmux)
• You need PostgreSQL

Setup apps

After cloning this repo, your need to :

1. Simple Rest API

• Go to Rest API : cd rest
• Install dependencies : mix deps.get

2. GraphQL API Server

• Go to Rest API : cd api
• Install dependencies : mix deps.get
• Setup database and run seeds : mix ecto.setup

Go to the moon 🚀

• At the root folder : $ overmind start
• Open your browser on GraphiQL : http://0.0.0.0:4000/graphiql

(See REST-API http://0.0.0.0:8880/users/)

Query Examples

Query all authors (Via Rest API)

query {
  authors {
    id
    name
    age
  }
}

Query all posts (On database)

query {
  posts {
    id
    title
    description
  }
}

Create a post

mutation CreatePost {
  createPost(title: "Second", description: "We're off to a great start!") {
    id
    title
  }
}

✨✨ Start magic (MIX BOTH) ✨✨

query {
  posts {
    id
    title
    description
    author {
      name
      age
    }
  }
}
