This package simplifies dispatching process, you shouldn't care about service injection as we provide more declarative way to dispatch events out of the box.Import the module into your root application module: is a function that allows you to decorate methods and properties of your components, basically arrow functions are properties. I had the second implementation but I wasn’t sure f it was the right thing to do. The Dispatch. It acts as a single source of truth for your application's state, providing simple rules for predictable state mutations.
@ngxs-labs/dispatch-decorator is another interesting experimental feature for NGXS developed by NGXS Labs.Even though it’s still not part of the official NGXS package, it’s likely to become an official feature shortly. Private self-hosted questions and answers for your enterpriseProgramming and related technical career opportunitiesNo need to dispatch another action just to update the loading to true. Would you agree? Even though it’s still not part of the official NGXS package, it’s likely to become an official feature shortly. Also, shouldn’t I use switchMap for both?
@O.MeeKoh and one more thing - I would personally patch the state on success in the Yeah that is a good point. I will definitely implement both of those tips.
If we return the Observable, the framework will automatically subscribe to it for us, so we don't have to deal with that ourselves.
@ngxs-labs/dispatch-decorator is another interesting experimental feature for NGXS developed by NGXS Labs. Additionally, if we want the stores dispatch function to be able to complete only once the operation is completed, we need to return that so it knows that.

I'm curious though, does the postService which returns an array of posts return a single observable or a single observable which then emits multiple higher order observables (inner observables)?You could start with dispatching the loading action:or I believe you could just change the state right away:Thanks for contributing an answer to Stack Overflow! reset ()); The Observable that a dispatch returns has a void type, this is because there can be multiple states that listen to the same @Action , therefore it's not realistically possible to return the state from these actions since we don't know the form of them. Stack Overflow for Teams is a private, secure spot for you and Another fundamental priority in development is trying to limit the use of boilerplates to the minimum. The store is a global state manager that dispatches actions your state containers listen to and provides a way to select data slices out from the global state. I have the following code for fetching all of my postsThis works, however, I want to perform another dispatch prior to calling my post service.
It is possible that the user may click on this button multiple Since I am retrieving all posts I think switchMap is what I want for both dispatch. Definitely should be mergeMap. Who should subscribe to NGXS async action - the dispatch action caller or the @Action handler? Another example would be when we are unit testing and need the state to be a specific value for isolated testing. In general, it’d be good practice to keep the code as simple as possible and to avoid verbosity to keep technical debt under control.For me, there’s nothing more frustrating than a file with hundreds of lines of code, and that’s why I’m always looking for ways to write in a cleaner and clearer way.

But its really up to you if you want to have an action to toggle loading state. Should ngxs support returning an action,Observable
