The user interacts with the UI triggering a fake action that doesn’t update the store, it serves as an initiator for some kind of async operation against a server, and if the operation is successful we update the store to reflect such success, on the contrary, if the operation fails, we show an error and if needed we update the store to reflect the error.

In the meanwhile, the user is staring at some spinner or loading indicator and the UI won’t reflect any…

Oh, don't worry, it’s not like you need to throw your existing REST API into the garbage can, I am going to show you you can add a GraphQL Layer on top of your existing REST API.

For the sake of having a running API that…

Ever since I started creating my first REST API, I felt something was missing. As an engineer, your brain is forced to think about optimizations, resource usage, and last but not least, developer experience. So as my knowledge of developing REST APIs grew, I started trying to give the consumer of the API the ability to customize the response he got based on the resources he needed.

Let’s…
