SimpleGraphqlClient

Simple Graphql client for elixir!

Why

Q: There is a lot of others GraphQL clients for elixir, why creating another one.

A: Because some of them wants you to interpolate variables directly into your query string, and IMHO that is not best approach, some of them are too complicated for just pick them up. And some of them extremely cool like Maple but do not fit into general usage.

Usage

Query/Mutation example

iex>
query = "query users($name: String){users(name: $name){name}}"
SimpleGraphqlClient.graphql_request(query, %{name: "Boris"})
# Will produce
{:ok,
%SimpleGraphqlClient.Response{
  body: {:ok, %{"data" => %{"users" => []}}},
  headers: [],
  status_code: 200
  }
}

Subscription example

sub_query = "
  subscription testsub {
    userAdded{
      email
    }
  }
"
SimpleGraphqlClient.absinthe_subscribe(sub_query, %{}, &IO.inputs/1)

# Will produce 
%{"userAdded" => %{"email" => "testuser@example.com"}}

More examples

You can find more examples in test_app/test/graphql folder

Configuration

For configuration i suggest to write your own wrappers of &graphql_request/3 or any subscribe function. If you want to pass Authorization parametrs to WS connection, please encode them into url.

Installation

def deps do
  [

Roadmap
