Overview

GraphQL Demo App

This project was created to show how we use GraphQLBundle in our projects.

To ilustrate this we created simple backend application witch provide API endpoint for React Example TODO app (source code and how to run it you can see here).

How to run

To run backend you need clone this repo and:

If you have docker installed, just type this in project root:

docker-compose up -d

This command will run containers and exposed port will be 8500.

API endpoint: http://localhost:8500/graphql
If you have web stack installed, run:

php bin/console server:start

API endpoint: http://localhost:8000/graphql

Sending requests

Now you can easily send request to endpoint, for example:

$ curl -XPOST 'http://127.0.0.1:8000/graphql'

Response:

{
    "errors": [
        {
            "message": "Must provide an operation."
        }
    ]
}

Now let's specify query in request content:

$ curl -XPOST 'http://127.0.0.1:8000/graphql' -F 'query={ todos { id } }'

Response:

{
    "data": {
        "todos": [
          {
            "id": 129
          }
        ]
    }
}

GraphiQL extension

To run GraphiQL extension, just open endpoint + /explorer in your browser, for example http://localhost:8000/graphql/explorer.

Configuration for React example Todo app

If you have installed React Example TODO application and want to use our endpoint, you need to change endpoint in server.js on line 10:

Access denied error when running demo app for the first time
I am trying to run the GraphQLDemoApp for the first time, so I downloaded the repo and run the command:

php bin/console server:start

I am getting the correct (error) response to 'http://127.0.0.1:8000/graphql' but when I am trying to specify query, this is what I get:

| => curl -XPOST 'http://127.0.0.1:8000/graphql' -F 'query={ todos { id } }' { "errors": [ { "message": "An exception occured in driver: SQLSTATE[HY000] [1045] Access denied for user \u0027root\u0027@\u0027localhost\u0027 (using password: YES)" } ] }

What am I missing here?

Documentation

Is it possible to create documentation that explains how to go from fresh install of the bundle, to responding with serialized entities? There seems to be discrepancies between the main bundle docs, and what's in the demo app. Also, it seems like a bit of a jump from "Hello World" to all the included additional files being used here. What do they do?
Is the expectation that someone will just dig through the code and figure it out?
