🚀[FEATURE]: ROOT_STATE_TOKEN and FEATURE_STATE_TOKEN should be part of public API.

[TheCelavi]

Relevant Package

This feature request is for @ngxs/store

Description

Each state (service decorated with @State() decorator) must be injectable and has to have @Injectable() decorator. State is registered within service container with NGXS module.

However, there are times when we would like to process of initialisation/construction of states using service factory, which means that @Injectable() decorator is not of interest.

If given tokens are part of public API, this edge case could be supported as well.

Describe the problem you are trying to solve

Register state class within service container using service factory.

Describe the solution you'd like

ROOT_STATE_TOKEN and FEATURE_STATE_TOKEN as public injection tokens.

Describe alternatives you've considered

Complex initialisation of state services is not possible without service factory, so no viable alternative exist, that is, registered service would have more complexity than necessary.
