Project to learn how GraphQL works

I've made this project just to learn how GraphQL works with NodeJS and possible tools to work with it

It's really simple to use

• Git clone it
• If you have docker, just docker-compose up --build
  • Don't forget to put your database uri on app.js file
• if you have yarn:
  • yarn run start:hotreload to run with nodemon, it will reload the server once you change one file inside the project
  • yarn run start to run as a normal node app
• if you don't have yarn:
  • npm run start:hotreload to run with nodemon, it will reload the server once you change one file inside the project
  • npm run start to run as a normal node app

This project uses ApolloEngine. It's a gateway to your GraphQL projects that outputs a bunch of metrics for you. Since performance reports until what are the most used querys. Inside initialization/express.js there is

const engine = new ApolloEngine({
  apiKey: 'service:DavideCarvalho-Demolay:0oe2ZfdbsEoHV6mNXe8Zuw'
 })

Change this apiKey to yours (just go to Apollo Engine Website and click on "Get Api Key"). It will take you to the page where you can create an account using your github account and then create a project. Inside this project, get your api key.

Before continuing. I recommend you to use Insomnia to make those queries, it's a lightweight simple to use REST and GraphQL Client.

This project has an authentication layer with JWT too. When the project starts, it create an user called root with password root and cid 1 so you can make a query to GraphQL like this:

query ($login: LoginInput) {
  login(login: $login) {
    name
  }
}

passing those as query variables:

{
	"login": {
		"cid": "1",
		"password": "root"
	}
}

Get the token from the header (It's named "Authentication") and put it on the header of the rest of the requests.

Or you can change this line of code on initialization/express.js

consign()
  .include('middlewares')
  .then('models')
  .then('graphql')
  .then('api')
  .then('routes')
  .into(app);

To this:

consign()
.include('models')
.then('graphql')
.then('api')
.then('routes')
.into(app);

Now you're free to send requests without getting the token.
