Apollo-graphql learning project

I'm learning Graphql so I created this project that uses the Apollo GraphQL server over express, using an array of users as mock data.

** I will work on a typescript version using more data **

After cloning this repo and running npm install

Start the server with npm start

The Apollo client will start at localhost:8080/graphql

Queries

Retrieve all users:

Query {
    getAll {
        # Fields are id, name and username
        name
        email
    }
}

Retrieve one user's information using its id:

Query {
    getOne(id:1) {
        name
        email
    }
}

Mutations

Create a new user

Mutation {
    addOne(data:{
        name: "your name",
        email: "your email"
        # id is automatic
    }) 
}

Delete a user

Mutation {
    # user id
    deleteOne(id:1){
        status
        message
    }
}

Update user information

Mutation {
    # user id
    updateOne(id:1, data:{
        # not provided fields will have the same value
        name:"new name"
        email:"new username"
    }){
        status
        message
    }
}

That's all, thank you
