海外TECH	DEV Community	Progressive Reactivity in Angular	https://dev.to/this-is-angular/progressive-reactivity-in-angular-1d40	Progressive Reactivity in AngularThe more stateful your application is the more likely you will run into inconsistent state or state that doesn t react For example A user opens a message but the unseen message count doesn t react There are many ways to code reactively in Angular from way binding yes to advanced RxJS Some teams decide on a single application wide strategy which means the strategy for every feature will be as complex as the most advanced feature This reduces productivity and happiness Other teams prefer not to have any single strategy but to allow each developer to come up with the easiest way to develop each feature independently adapting the complexity of the solution to the complexity of the problem This is fast at first but complexity is rarely staticーit is impossible to anticipate every user need and every requirement change This matters because at every stage there are multiple ways of handling higher complexity and some of them are dead ends They can handle the next level of complexity reactively but they have limitations that cap them at that level They are also significantly different from the solutions that can handle further levels of complexity so you have to go backwards before you can go forwards again So we don t want premature complexity but we also don t want to get stuck with an awkward mess that is hard to adapt to higher complexity The ideal strategy would be simple at the very beginning but also easy to adapt to higher and higher complexity at any stage How do we know what syntax to avoid then First we need a solid understanding of the difference between reactive and imperative code Progressive Reactivity Rule Keep code declarative by introducing reactivity instead of imperative code Minimal syntax can grow in many possible ways both reactively and imperatively so we need to recognize the difference between reactive and imperative code Reactive code is completely self defined Nothing else tells it how to change It manages its own behavior by declaring clear data dependencies This is reactive a new BehaviorSubject b this a pipe delay Clear dependency on a This is imperative a b number undefined No dependency hereconstructor setTimeout gt this b changeA newA number this a newA setTimeout gt this b newA Part of what defines b has been broken away from b s declaration You do not know how b will behave by looking at b s declaration or at any single setTimeout It s scattered This is why reactive code is so much easier to comprehend But imagine if b never changed It just stayed as undefined Then its initial declaration would describe its behavior completely So it is already completely declarative just as it is No RxJS needed All reactive code is declarative but not all declarative code is reactive Declarative code is the complete absence of imperative commands controlling state from scattered out of context places Since we are trying to avoid inconsistent state which easily happens with imperative code declarative code is really what we are after It is only as features become more interactive that code must become both declarative and reactive As long as you do not write imperative code your code is declarative no matter what syntax you use This means you can start with minimal syntax and only later when you need it to change over time modify its declaration instead of having code elsewhere tell it how to be So always write declaratively and write reactively when it is required to keep code declarative It also doesn t hurt to err on the side of more reactivity if you anticipate higher complexity in the future Alright We are ready to look at the first levels of complexity Level Static Contentconst b is not reactive Neither is this lt h gt Hello World lt h gt And that s okay There is no risk of imperative changes causing inconsistent bugs All static content is declarative Level Shared StateImagine a simple color picker like this Imperative TrapBefore frameworks like AngularJS a common way to implement this would have been something like this lt div id color preview class aqua gt aqua lt div gt lt button id aqua class active onClick changeColor aqua gt aqua lt button gt lt button id orange onClick changeColor orange gt orange lt button gt lt button id purple onClick changeColor purple gt purple lt button gt lt script gt var currentColor aqua function changeColor newColor document getElementById color preview className newColor document getElementById currentColor className document getElementById newColor className active lt script gt And then someone would notice that the color name never changes So you would change the st line of changeColor to these lines var previewEl document getElementById color preview previewEl className previewEl innerText newColor While we were writing changeColor not every bit of the template was necessarily on our minds Edit While writing this example I intentionally forgot to update color preview s text But I unintentionally also forgot to update currentColor newColor I only noticed this now while implementing this in StackBlitz So basically imperative code and forgotten DOM updates used to be the norm The DOM was not reactive Reactive Solution to Level Immediate ChangesThen Angular and others came along and now we can implement features like this declaratively Each part of the template can once again declare what it is permanently even though it is no longer static content The difference is that instead of declaring static content each piece declares a static relationship to a value that changes color preview s class was written as aqua before Why Because that is what the color started as So we write class currentColor because that s what it really is across time Same with the inner text So we write currentColor for that button aqua started with the class active Why Because we know that the button should look active when the current color is aqua So we write class active currentColor aqua What does the button do Well it changes the current color to aqua So that would be click currentColor aqua It s easy when we go piece by piece to know why everything started out as what it was and realize that its current state is always related to a higher shared state called currentColor We can write entire templates and be confident we didn t miss anything lt div id color preview class currentColor gt currentColor lt div gt lt button class active currentColor aqua click currentColor aqua gt aqua lt button gt lt button class active currentColor orange click currentColor orange gt orange lt button gt lt button class active currentColor purple click currentColor purple gt purple lt button gt Component class currentColor aqua A critical thinker might notice a contradiction now I m excited about our declarative templates but currentColor aqua is not declarative currentColor s changes are dictated by imperative commands scattered across the template But this is the best we can do for a couple of technical reasons We can only define the template once but it should be at both the top and the bottom of the causal chain currentColor depends on the button clicks but the buttons depend in turn on currentColor It s not possible to declare these relationships without circular references If we wanted currentColor to react to the button clicks it could not be shared between components because other components don t have access to this button The best we can do is this Every user event in the template pushes the most minimal change to a single place in our TypeScript and then everything else reacts to that Syntactic Dead Ends way data binding is often discouraged but it s actually fine at this level of complexity It s as declarative as anything else as long as there isn t derived state that needs to update It s not a syntactic dead end either because it s easy to change lt input ngModel currentColor gt to lt input ngModel currentColor async ngModelChange currentColor next event gt But something to watch out for is template logic For example if we had currentCount instead of currentColor we might end up doing simple math inside our templates like this current count is currentCount Next count currentCount This is fine because it s easy to move elsewhere but at a certain level of complexity either the processing can t be done in Angular s templating language or we want to be more expressive with something like nextCount In that case we want to officially treat it as derived state That will be the topic of the next article in this series	2022-07-05 09:23:12
