nick-origin-graphql v0.2.1

Origin GraphQL

This experimental package provides a GraphQL interface to Origin Protocol intended to be consumed by ApolloClient. It uses apollo-link-schema to expose a client-side GraphQL server that can also be used server side.

This means a UI is able to leverage the power of GraphQL without depending on a centralized server. The only server side dependencies are an Ethereum node and and an IPFS server.

A GraphiQL demo is available here
