Hasura Hub is a collection of boilerplates and readymade applications that you can clone, modify and deploy to kickstart your application development. For example - a react native project is wired up with a NativeBase UI kit, expo.io & a Hasura backend that you can clone and deploy in minutes. Hub also has sample applications for a slack bot, a messenger bot, e-commerce schemas, a simple AR app with AR Kit & Clarifai, etc.
The feature of Hasura that makes a ’hub' of instantly deployable projects possible is that every Hasura project is declarative, i.e, everything from source code to migrations to configuration is version controllable. The hasura cli, api console and hub are designed around and deeply integrate with this feature.
