海外TECH	DEV Community	What The Facade?!	https://dev.to/juniordevforlife/what-the-facade-22d4	What The Facade What The Facade Are your components hundreds of lines long Are your services bare Have you ever copy and pasted a function from one component in to another If you answered yes to any of these stick around Today we ll be taking a look at how the Facade design pattern can help us write more maintainable code in an Angular application What is the Facade Design Pattern The Facade design pattern is a Gang of Four structural design pattern The objective of the design pattern per the Gang of Four is to Provide a unified interface to a set of interfaces in a subsystem Facade Pattern defines a higher level interface that makes the subsystem easier to use How does this translate to Angular Imagine we re creating a todo list app and that we ve already created the backend API and we now need to make the UI We could just make the calls to the API directly from our components or we could create a service that handles the API calls handles any complex business logic and just gives our component the data it needs to handle the view What are the benefits of the latter Well for starters our component s will be cleaner They ll only need to interact with the service vs interacting with the API directly Another benefit is that we can reuse the same methods over and over again and only define them once A third benefit is that if we need to swap out our API or make any changes to the business logic we only have to make those changes in one place Angular Facade Pattern A Perfect MatchAngular advocates for keeping your components lean and outsourcing your business logic to your services Per the Dependency Injection section of the docs Angular distinguishes components from services to increase modularity and reusability By separating a component s view related features from other kinds of processing you can make your component classes lean and efficient The Angular Style Guide reinforces this concept by stating Do limit logic in a component to only that required for the view All other logic should be delegated to services We can now see that the Facade design pattern isn t some obscure pattern or buzzword you can throw around the office to sound like you know what you re doing It appears that the Angular team is pretty much advocating for its use Sure you can go and create behemoth components and make services an afterthought While the Angular docs do state that Angular doesn t enforce this separation of view and business logic they ve given us a framework that allows us to easily implement the Facade pattern Facade Pattern in ActionLet s use the Free Dictionary API and create a component that displays the definition of a word Here is the dictionary component template lt h gt Coolest Dictionary Ever lt h gt lt form form ngForm submit submit gt lt label for search term gt Search lt label gt lt input type text id search term name searchTermText ngModel searchTerm gt lt button type submit gt Search lt button gt lt div ngIf definitionArr gt lt h gt Definition lt h gt lt ul gt lt li ngFor let definition of definitionArr gt definition lt li gt lt ul gt lt div gt lt form gt And here is the dictionary component class import HttpClient from angular common http import Component OnInit from angular core import map from rxjs operators Component selector app dictionary templateUrl dictionary component html styleUrls dictionary component css export class DictionaryComponent implements OnInit constructor private http HttpClient ngOnInit searchTerm string null definitionArr string null submit if this searchTerm this getDefinition getDefinition this http get this searchTerm pipe map result gt result meanings map meaning gt meaning definitions definition subscribe result gt this definitionArr result As you can see we ve got a template driven form We display the definitions in the definitionArr array if any exist We have two methods in the class submit and getDefinition The submit method is called when we submit the form by clicking the search button which in turn calls getDefinition The getDefinition method makes a call to the free dictionary API then maps the result to the definitionArr property The code works that means we can call it a day right Let s ask a couple of questions What happens if we want to use the getDefinition elsewhere in the codebase How hard would it be to swap out the Free Dictionary API with a different API Now imagine that we copy and pasted the getDefinition in a couple of other components and answer the question Let s RefactorI m going to create a dictionary service and move our business logic from the dictionary component to the dictionary service Let s check it out We ll start with the dictionary component class import Component OnInit from angular core import DictionaryService from dictionary service Component selector app dictionary templateUrl dictionary component html styleUrls dictionary component css export class DictionaryComponent implements OnInit constructor protected dictionaryService DictionaryService ngOnInit searchTerm string null submit if this searchTerm this dictionaryService getDefinition this searchTerm This looks a lot slimmer We are no longer importing the HttpClient or the map operator The getDefinition method is completely gone We also see that the definitionsArr property is gone We ve injected the newly created DictionaryService and are using it in the submit method Next let s look at the template lt h gt Coolest Dictionary Ever lt h gt lt form form ngForm submit submit gt lt label for search term gt Search lt label gt lt input type text id search term name searchTermText ngModel searchTerm gt lt button type submit gt Search lt button gt lt div gt lt h gt Definition lt h gt lt ul gt lt li ngFor let definition of dictionaryService definitions async gt definition lt li gt lt ul gt lt div gt lt form gt What s new here Rather than iterating over the definitionsArr property we re now iterating over the dictionary service s definitions observable using the async pipe Now let s check out the new DictionaryService import HttpClient from angular common http import Injectable from angular core import Subject from rxjs import map from rxjs operators Injectable providedIn root export class DictionaryService constructor private http HttpClient private definitionsSubj new Subject lt string gt definitions this definitionsSubj asObservable getDefinition searchTerm string this http get searchTerm pipe map result gt result meanings map meaning gt meaning definitions definition subscribe res gt this definitionsSubj next res We were able to use most of the logic from the component s getDefinition method However we re now calling next on the definitionsSubj Subject with the result We ve also created an Observable definitions This is the Observable that we are using in the template file with the async pipe With this refactor we d be able to use the getDefinition method anywhere in our app Our dictionary component is cleaner If we ever needed to swap out the Free Dictionary API with a different API we d only have to do that in one place Our component should be easier to test There s quite a few benefits that come along with the refactor ConclusionIf you re feeling like your components are too complex maybe you ve got the same method copy and pasted across several components or maybe you re bringing in too many dependencies in your component which is making it harder to test and or make changes to existing logic it may be time to consider using the Facade pattern The example used today was just the tip of the iceberg This pattern can be used to separate complex business logic from your component make working with state management easier handle communication with a backend service and more If you want to check out the Stackblitz for this post here s the link
