Software Architecture Patterns for Front-End Development

Back-end development makes extensive use of research and practice pertaining to a variety of software architecture patterns. Front-end development not only has a short history, but it also lacks the kind of well-established methods that are used in other fields. Despite this, over the course of the past several years, a variety of architectural best practices have emerged thanks to the rise in popularity of different front-end frameworks like Angular and React, amongst others. Let's take a look at some of the patterns that have become an indispensable component of front-end projects in today's world.

"MVC," which stands for "model-view-controller," was one of the first patterns that were established many years ago. In this design, you would try to give different actors different tasks, such as putting together the presentation and handling the data. MVC was one of the original patterns. Over the course of time, variants of MVC, such as MVP and MVVM, have been developed. Even though Model-View-Controller (MVC) has been replaced by other systems, it still has a big effect on modern front-end development in many ways. example: Separation of Obligations and Concerns (SoC).

Modular Architecture —If we look at the Angular Framework as an illustration, we can see that the application is broken up into many modules based on the various domains that it serves. Each Module comes with its own NgModule, which functions as a separate container. These NgModules are then grouped together into AppModules, which function as the mother of all modules. Additionally, you should give some thought to the Core Module and the Shared Module.

Micro Frontends — Simply extending the microservices architecture to the front-end layer is all this entails. As the project grows and adds more features, it gets harder and harder to keep track of all of its dependencies, builds, and deployments. Based on the micro frontends idea, the front-end application will be split into different areas for different use cases. This use case area either has members of the front team who are responsible for it, or, in large applications, there are different teams covering end-to-end micro areas.

Component Architecture — This design, which is characterized by a more fine-grained separation of various presentation units inside components, is also inspired by SoC. This means that if we have a user interface for listing books, for example, we will need to make a book component with all the code needed to show a list of books. We would have.html files for view;.ts files for component-specific business logic;.scss (or.css) files for style; and. spec.ts files for testing in the book component folder.

The Dumb-Smart Components pattern is the subsequent pattern that was started by SoC. Here, we have two different kinds of components: dumb components, which are simply used for display; and smart components, which are responsible for data flow and separate data injection from presentation. This is accomplished mostly through the use of two-way data binding in the Dumb Component, which is based on @Input and @Output (EventEmitterT >). Using this annotation, Dumb Component either gets data from Smart Component that is useful, or it sends data to Smart Component that is useful. Most of the time, smart components will either inject a service or a facade and handle the flow of data. Please see the pertinent gist here.

State Management — Modern front-end frameworks are typically built around this concept, which is a data store instance that is referred Known as "State Management." It would be called Redux in React and NgRx in Angular (actually, both based on the Redux Pattern). The building elements that function in event-based asynchronous data streaming include selectors, stores, reducers, actions, and effects. Watch the documentary for further clarification.

Unidirectional Architecture: This mostly ties up with the concept of reactive programming. Data flows in only one direction in modern front-end frameworks, which are powered by data flow streams. The data can only flow in one direction, which is always in the direction of the view. In turn, the view will trigger a variety of other actions. This results in improved control over the data. When dealing with data streams, utilizing a variety of libraries like RxJs, NgRx, and Flux offers a wide range of features.
