Selectors are functions which allow accessing any relevant information stored in the state. They are helpful, especially because redux-rest-easy state is generated and managed by the library itself.
There are 3 types of selectors :
- linked to a request: helpful to map a component to the payload of a specific request
- linked to a resource: helpful to map a component to a whole resource
- linked to a resource Id: helpful to map a component to a single item
And for each type, here is a sneak peek of what information you can access:
- the payload of the request/resource/resourceId
- could we perform on the request/resource/Id
- are we performing on the request/resource/Id
- has the request/resource/Id succeeded
- has the request/resource/Id failed
