I have NgRx-Effects in place and related action to fetch data from the service and that updates my initial state let's say 'schoolData'is the state property name, which works very well.

Now, I have some event on the form from which I want to update the same state as aforesaid where in I will transform the data and will update the state.

I am aware of the asynchronous way of managing state, but In my case can the effect be used for updating state synchronously?

snippet from NgRx.io: says it can have that as well.

Effects perform tasks, which are synchronous or asynchronous and return a new action.

Can anyone has a working example of this or can lead me into the right direction?

CodePudding user response：

The effect logic itself is called synchronously. When you trigger an async call inside of it, like fetching data, it "becomes" async.

But: Effects are made for isolating "side effects" like async calls. When you don't have to do any impure side effects that you want to isolate, I would rather place this state update logic inside a reducer.
