Is it possible for me to trigger an action from within a reducer?

edit

Technically, it is possible to trigger an action from within a reducer, but this is generally not recommended because it can lead to unexpected side effects and make the code harder to reason about.

Reducers should be pure functions that only take in a state and an action, and return a new state based on the action type and payload. They should not modify the original state or trigger any other actions.

If you need to trigger another action based on the current action, it is better to do so from the component or middleware layer. This will keep the logic separated and make it easier to debug and test.
