The server is host on Heroku, and the GraphQL API interface can be accessed at this URL : https://lebonangle.herokuapp.com/

  /efrei-expo-2019/server/$ npm install
  /efrei-expo-2019/server/$ npm run start

As server is on the same repository as client, we had to push manually the server tree to Heroku, like so :

  /efrei-expo-2019/$ git subtree push --prefix server heroku master

There are 3 models that can be used :

• Users : represents the users that can use CRUD on Posts
• Posts : represents announces of products created by Users
• Categories : represents Posts categories, only 1 by post

Each one of these models is persisted on a PostGres database and can be accessed through GraphQL

Each model as at least 2 queries available :

• GET ALL
• GET ONE BY ID

Here is an example to get one user by using his ID :

query {
  user(id: 3) {
    firstname
    lastname
    city
  }
}

Each model as at least 3 mutations available :

• CREATE
• UPDATE
• DELETE

Here is an example to create an user :

mutation {
  createUser(data: {
    firstname: "John"
    lastname:"Doe"
    city: "Paris"
  }) {
    id
    firstname
    lastname
    city
  }
}
