Google’s Angular is a TypeScript-based, open-source JavaScript framework for front-end developers. Google maintains it, and its major objective is the creation of single-page applications. Angular is a framework that offers programmers a standard framework to work with and has indisputable advantages. It gives users the ability to make huge apps in a manageable way. Most of us are aware of the differences between libraries and frameworks. The library does not support the construction of an entire architectural system. In contrast, the architecture of the entire application is built using the framework. In essence, Angular is made to build single-page web applications, which are complicated corporate applications.
Implementation of the Angular framework includes:
- Modularity;
- Animations;
- Routing;
- Work with the backend;
- Data storage/processing/display;
- Work with forms and templates, and more.
Explain The Different Versions Of Angular.
First Version Of Angular:
The original Angular framework, currently called Angular JS, could have been better. However, a tonne of projects continues to utilize this version. The project was later completely rewritten by the development team.
Second Version Of Angular:
The brand-new version is called Angular 2 or Angular without an index. It had a different framework because it was drastically different from the first. There were certain issues since projects found it difficult to transition from the previous version to the new one. Everything has to be written over again. Conceptually speaking, Angular has grown more straightforward, technologically, and sophisticated. Versions 4, 5, and most recently, version 9 followed Angular 2 in development. It is vital to remember that the release of version 2 has prevented any substantial changes from happening. From the second to the seventh version, everything is completely compatible. Therefore, there is no longer a need to learn everything.
Angular 4:
Angular 4 was introduced at the end of 2016 after version 3. It was completed to assure clarity brought on by the mismatched router package version, which had already been provided as v3.3.0. Angular 4 introduced a new set of capabilities, including the HttpClient library, a more effective and approachable tool for building HTTP requests. In March 2017, the final draught was made available.
Angular 5:
On November 1, 2017, Angular version 1.1 was published. Support for advanced web applications and the build optimizer are two of Angular 5’s most significant enhancements.
Angular 6:
Tools and add-ons for Angular 6 put a lot of emphasis on the framework itself. As part of the course, students learned about updating, Angular elements, Angular Material + CDK components, CLI workspaces, and library support.
Angular 7:
Since October 2018, Angular 7 has introduced performance improvements, Angular Material and Angular CLI prompts, virtual scrolling, improved selection accessibility, and Angular CLI prompts for mobile development.
Angular 8:
Angular 8 was released in May 2019 and included several new features, including dynamic imports for lazy routes, network robots, TypeScript 3.4, and support for Angular Ivy.
Angular 9:
In February 2020, Angular 9 was made available. Version 9 introduces the Ivy compiler and runtime by default for all apps. TypeScript versions 3.6 and 3.7 are compatible with the newest version of Angular. The most popular version of Angular comes from the Ivy compiler.
Angular 10:
Version 9 of Angular was followed shortly by version 10. New functions were added, including a new default configuration for the browser, warnings about CommonJS import, and a new date range selector (Material UI library).
Angular 11:
On November 11, 2020, Angular 11 was made available. This framework includes changes for Operation Byelog, better reporting, and logging, quicker builds, automatic font inlining, and other features.
Angular 12:
The update was made available on May 12, 2021. The View Engine, scheduled to be eliminated from the following major release, is being phased out in Angular 12 in favor of Ivy. Certain aesthetic upgrades and document updates have also been implemented to make learning Angular easier.
What Is The Architecture Angular?
It illustrates the Angular fundamental architecture, including modules, components, templates, services, routers, pipes, and directives.
Let us examine each component individually to determine why it is present in the architecture as it is:
● Module:
Structured application units that include a particular logic. These are Angular structures used to contain certain components, directives, and services that are connected by a predetermined logic.
● Component:
Class in typescript that saves data and contains the logic for presenting that data in a template (representation).
● Template:
A fragment of HTML code with the addition of special syntax. The template is specified in the component and is part of its configuration.
● Service:
Typescript classes in Angular carry out operations relating to obtaining, saving, and processing data. The service can set up a communication channel between various application parts. Additionally, it is preferable to separate business logic, various computing jobs, and logging responsibilities from the components. As a result, working with the view will be the primary emphasis of the component code.
● Router:
Intended to flip between screens in order to display different content. More specific constructs, like directives and pipes, are simpler to demonstrate in code than to explain in words.
What Are The Pros And Cons Of Angular?
Pros Of Angular:
Accurate Documentation:
Angular has detailed documentation of important information. It lets developers get straight to the hint for the project.
Has Support From Google:
It is a reason why Angular as a platform is reliable. Yes, it is a little text but not the least advantage of Angular.
Many Third-Party Components’ Ecosystem:
Thankfully to how famous Angular is, we got many instruments for developing an app. As a result, we got a productivity improvement.
Component-Based Architecture:
Thus, after all that we got in the 2nd Angular, developers had to move to the architecture of components from the model view controller (MVC). The advantages here are replacing and disassembling components but reusing them in other program’s parts. In addition, the independence of the components facilitates the testing of the web program and ensures the smooth operation of each component.
Ivy Reader:
The feature that converts everything into JavaScript: from components to templates. We got it with the sixth version of Angular. It also lets an app load faster cause of how it removes unused code from it.
Dependency Injection:
With the second version of Angular, developers got a divided tree of dependency injectors. It could be changed or restored, avoiding reconfiguring all components. Injection dependence is a rather controversial advantage of Angular. Simple in the English language, dependency input means one object establishes dependence on other items. All of them determine the connection between different components. Also, it shows every change in one part of the code and how they affect other parts.
Cons Of Angular:
Poor SEO Options:
Angular received much bad feedback about its SEO accessibility. They only see the basic page template. Some search engines need to see such diversities. In addition, heavy links to a one-page application are difficult to index. Frequently, developers make more effort for optimization.
Tough To Learn:
Angular is difficult to learn from scratch. Juniors will need help managing all those components. Those components are very readable, but they are very hard to manage.
Adversity With Backward Compatibility:
Need to do more than go from AngularJS to Angular. It will not work. The documentation for Angular includes information on how they thwart migration. Nevertheless, we should remember that previous Angular versions are fully compatible with the reverse.
NgRx:
There is also, as we can call this framework, a great addition to Angular. It could be so useful for a project that we cannot discuss it! This framework controls the creation of explicit programs, maintaining a single state, and using actions to express state changes.
Conclusion:
A web development framework built on TypeScript called Angular is recommended for large projects. However, it also functions well for smaller ones. The community of web developers’ affection and support has aided Angular’s rapid growth and adoption.
