Wundergraph

Wundergraph provides a platform to easily expose your database through a GraphQL interface.

Example

For a full example application see the example project

#[macro_use] extern crate diesel;
use wundergraph::prelude::*;

table! {
    heros {
        id -> Integer,
        name -> Text,
        hair_color -> Nullable<Text>,
        species -> Integer,
    }
}

table! {
    species {
        id -> Integer,
        name -> Text,
    }
}

#[derive(Clone, Debug, Identifiable, WundergraphEntity)]
#[table_name = "heros"]
pub struct Hero {
    id: i32,
    name: String,
    hair_color: Option<String>,
    species: HasOne<i32, Species>,
}

#[derive(Clone, Debug, Identifiable, WundergraphEntity)]
#[table_name = "species"]
pub struct Species {
    id: i32,
    name: String,
    heros: HasMany<Hero, heros::species>,
}

wundergraph::query_object!{
    Query {
       Hero,
       Species,
   }
}

Building

Depending on your backend choice you need to install a native library. libpq is required for the postgresql feature, libsqlite3 for the sqlite feature.
