Overview

Program basic_graphql_server shows a simple HTTP server that exposes a bare schema.

Example:

$ basic_graphql_server &
$ curl -g -XPOST 'http://localhost:8080/' --data-binary '{ "query": "{__schema{root_fields{name,description}}}"}'

{
  "data": {
    "__schema": {
      "root_fields": [
        {
          "description": "Schema entry root field",
          "name": "__schema"
        },
        {
          "description": "Provides the current server uptime",
          "name": "uptime"
        },
        {
          "description": "Provides the current server time",
          "name": "now"
        },
        {
          "description": "Query registered types by name",
          "name": "__type"
        }
      ]
    }
  }
}

 $ curl -g -XPOST 'http://localhost:8080/' --data-binary '{ "query": "query rootFields { uptime, now} "}'
 {
 "data": {
   "def": 177.898958761,
   "now": "2015-09-12T20:25:46.065224697+01:00"
 }
}
