About this fork
Currently in upstream Relay, the assumption is made that the id field is globally unique as specified in the Global Object Identification specification.
However, in our case this conflicted with an already existing id field in our schema that was being consumed by non-Relay clients, changing this would have broken those clients.
After deliberation, the conclusion was that the simplest solution would be to make it easy for people to fork Relay and change the hardcoded instances of id to whatever suits their needs.
It also became apperant that there is a chance that the GraphQL specification itself will gain a reserved ID field that may be used by tools such as Relay to for whatever identification purpose.
As of yet, the name for that future ID field most likely is going to be __id, which is what this fork uses. This fork will be maintained, as in, kept up-to-date with upstream releases.
You can install the packages as per the npm install <tarball url> documentation.

Update process
- If not previously done, add the upstream remote:
$ git remote add upstream https://github.com/facebook/relay.git - Fetch upstream changes:
$ git fetch upstream && git merge upstream/master - Check that the upstream changes do not re-introduce a hardcoded use of
'id'. If it does, submit a PR upstream to fix that. - Push changes to our remote:
$ git push origin __id - Create release with packages:
$ node release.js [GITHUB-TOKEN] - Afterwards, your git checkout will be dirty, there’s no need to keep those changes:
$ git checkout .
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.
