GraphQL + Postgres + DataLoader, in Go.

A simple example of using GraphQL to effectively retrieve data from a Postgres database.

How to run

1. Build a Docker image for a sample store database

   $ docker build -t store .

2. And then run it

   $ docker run --rm -p 5432:5432 store

3. Build the project

   $ go build

4. Then run the binary

   $ ./graphqldb

Now you should be able to able to send GraphQL reqests to http://localhost:8080/graphql. For example

$ cat <<EOF | curl -X POST -d @- localhost:8080/graphql | python -m json.tool
{
   "query": "{ 
        orders(first: 2) { 
            id, 
            time,
            customer {
                name,
            },
            products {
                name,
                quantity,
                price,
            },
        }
    }"
}
