Relay

Relay is a JavaScript framework for building data-driven React applications.

Declarative: Never again communicate with your data store using an imperative API. Simply declare your data requirements using GraphQL and let Relay figure out how and when to fetch your data.
Colocation: Queries live next to the views that rely on them, so you can easily reason about your app. Relay aggregates queries into efficient network requests to fetch only what you need.
Mutations: Relay lets you mutate data on the client and server using GraphQL mutations, and offers automatic data consistency, optimistic updates, and error handling.

Example

The relay-examples repository contains an implementation of TodoMVC. To try it out:

git clone https://github.com/relayjs/relay-examples.git
cd relay-examples/todo
yarn
yarn build
yarn start

Then, just point your browser at http://localhost:3000.

We actively welcome pull requests, learn how to contribute.

We have a community-maintained list of people and projects using Relay in production.
