Export data to Excel is very useful on the data list for nearly every web application. The export feature helps to download the data list in a table as a file format for offline use
I like the Redux concept. It allows developers to avoid state manipulation to be spread across the application, leading to difficult to detect inconsistencies, especially when dealing with asynchronous events such as calls to HTTP services, or handling real time update. It is not, however, an easy concept to grasp. It may look like an overthought solution that creates more troubles than it solves. Anyway, after a few years using
ngrx, I still don’t like it. And not only that, I was trying to avoid it when started a new project. Why?
Let’s start with the boilerplate issue. Whenever I needed to use
ngrx, I had to:
dispatchfunction to dispatch an action.
It’s not a big problem if it’s not often needed. But fetching data from API is what front end dev do, though! Effects can become huge and not so easy to maintain.
I have to admit, a part of our problem is that not all of our front end developers are familiar with the latest technology. They didn’t even know AngularJS or jQuery. And now with
Angular, they had to learn about components, modules, DI and so on. They also had to learn about
Observables, and other concepts that aren’t trivial. And then, suddenly with
ngrx, they also had to learn about
Selectors! Maybe I should’ve seen it coming, but even if they already felt comfortable with Angular, it seems that those concepts aren’t easy to grasp unless you knew
Redux(-ey) libraries before.
Whenever I was using
ngrx, I felt like maybe it could make more use of Angular. For example, instead of the big and ugly reducer, decorators should be used by default. Some libraries try to solve that problem, but they felt subpar to me, and they sometimes introduced even more complexity, like needing specific work to avoid problems with AOT compilation. If you’re using
ngrx, I recommend ngrx-actions.
My coworker had a very difficult time “getting”
ngrx, and he spent more time trying to understand
ngrx along with Angular than developing the application itself.
That’s why I have to look for a new alternative option. Two of them looked more mature and well-tested:
@Dispatchdecorator does it for you underneath.
ngxs. Instead of actions and dispatchers, just a plain service, even for async calls. I like their Router Store, it looks much simpler than what ngrx router has offered, which I gave up last year when trying to integrate it into my application. I haven’t applied it in any of my applications but probably will start to do it soon. Because a new front end developer will join our team next week.
