Client

Diana also provides a GraphQL client implementation.

Simple query

using Diana

Change headers

client.headers(Dict("header" => "value"))

Change serverAuth

Validating query

It is possible to validate the query locally before sending the request, only basic validations are carried out.

          neomatrix{
            nombre
