#MOBX VS REDUX UPDATE#

Redux requires that the update of state does not mutate the original state. In addition, we can combine multiple stores and share the references. You can have methods, control over what should be observable or not. Here, Mobx shines for those of you who like object-oriented programming. That separation allows us to reuse the domain in different applications.īecause we are not limited to JS plain objects, it seems natural to create its own classes for particular domain objects, as the authors suggest. MobX actually encourages having at least two separate stores, one for the UI state and one or more for the domain state. By keeping the state in one location, we make sure the data is not duplicated all over the app and it becomes easier to debug. We have a single source of truth in Redux. There is no need for normalization of data, as MobX observable clones the object, makes it observable and, therefore, makes sure that all changes are reflected in the store once we update any of the observable properties. set ( 'Amsterdam' ) // Prints: 'Amsterdam' set(newValue) respectively see observable.box(value) All you need to know if you go with an observable is that it will wrap the primitive in “a box” and the actual value getter and setter will be available via. Yes, primitives are not mentioned here because their values in JS are immutable and because of that they need to be treated differently. In MobX, we make properties, entire objects, arrays, Map and Sets observable. Unfortunately, even with the helper functions in Redux's Toolkit (e.g., createEntityAdapter) that still adds additional code. In Redux, we have to use primitives, arrays, or plain JS objects as data for our state.Īlso, there is a common practice when you store data in arrays, namely to normalize it for performance reasons. Data structure - what is inside the state? There is much less initial coding and many things happen behind the scenes, so you do not need to care about them in most cases. Nevertheless, if you are familiar with OOP, MobX will come naturally to you. But maybe handling all of the reducers, actions, middlewares, and other stuff makes it so easy to get fascinated by something else. I was going through the examples and I kept asking how that could work, but it does and apparently does it well. When I looked at the MobX documentation, I was like a kid who accidentally landed in a chocolate factory. If you ask me, I like it! Still, there is a lot to learn, but the simple basic setup with the Toolkit does the job. Especially when you have a bigger application with a lot of reducers and actions, you have probably already decided to keep the action types as constants in the strings, which is a good approach, but then there is even more code! Fortunately, the Redux Toolkit is getting more popularity and it is now recommended to write Redux logic. React is known for the serious boilerplate around the initial setup. Architectural freedom - implementation is unopinionated and can be used without any UI framework.Effortless optimal rendering - it makes sure all computations are optimized well and there is no need to manually do so,.

#MOBX VS REDUX CODE#

Straightforward - minimalistic, boiler-free code and no special tools required to operate it,.Similarly to the preceding library, its philosophy is described in 3 points: No surprise here, MobX is also a library for state management, it transparently applies functional reactive programming (TFRP) to make it simple and scalable. Changes are made with pure functions - pure functions by definition always return the same results for given parameters, can be executed always, and have no side effects.State is read-only - you cannot directly change the state, you should emit an action to do so,.Single point of truth – the state is kept in a single store,.

What is Redux?Īs stated at redux.js.org, it’s “a predictable state of container for JS Apps.” It was created by Dan Abramov and Andrew Clark in 2015.

There will not be that much code here and I believe you have already heard about Redux. That is why I decided to have a quick look at it. Sooner or later, we will move it to the MobX state, just as we did with the other apps.
