Sashko Stubailo, a Meteor developer, introduced Apollo, the new GraphQL-based data stack for modern apps. The goal of Apollo is to decouple the client and server components, allowing developers to work with a unified data stack that can be adopted in any app, regardless of the platform or backend technology used. Meteor's existing data system was compared to GraphQL, highlighting the benefits of using GraphQL, such as reduced roundtrips, self-documenting APIs, and abstraction between services. The Apollo project aims to create a principled, unified, and scalable API for all client apps, agnostic to what is going on with the backend. The team has been working on the Apollo Server and Client, with the latter expected to be released soon.
