Before we begin with angular, let's first understand what Single Page Application (SPA).
A single-page application (SPA) loads a single web page and updates the body content of that single page when new content needs to be shown using JavaScript APIs like XMLHttpRequest and Fetch.
Angular is a SPA framework.
The open-source Angular front-end development framework makes it possible to create creative, effective, and complicated single-page apps.
In order to reduce the heavy weight of unneeded code and create a lighter and quicker application, Google engineers created Angular v2+ back in 2012. Its structure is easier to comprehend and manage because of its modular architecture. Additionally, it facilitates task division among developers working on the same team, enhancing their productivity and teamwork and leading to the production of higher-quality code as a result.
Angular comes with a large range of useful tools, such as its own CLI, debugging tools, Angular Material, ng Bootstrap, etc. Developers may save a lot of time by using the CLI to create Angular projects, which is a somewhat challenging and time-consuming procedure if it is done manually from the beginning owing to the numerous settings, libraries, and files to install. The boilerplate code for components, directives, guards, services and other related concepts is also built and added. On the other side, it develops applications that can be deployed or used in browsers. Angular CLI is also used to test the application.
Typescript, a superscript of JavaScript, is used in Angular applications. Actually, Typescript simplifies JavaScript code, making it easier to understand and debug. It also offers better security since it supports types, classes, and interfaces and discovers errors early in the writing of the code. Additionally, typescript code allows auto-completion and refactoring, and it is simple to debug in the editor or online. Since Angular provides all the functionality that JavaScript provides, getter and setter methods are not necessary for the objects that Angular uses, which are POJOs.
The fact that Angular is a component-based design must be emphasized since it encourages code uniformity, sets a premium on code reuse, and makes unit testing simpler because components are autonomous units. In reality, all of the components, services, directives, pipelines, etc. are developed using the same design methodology. As an example, let's customize a component's look. Selector: will be called by other components. Each component has a decorator, which is specified as @Component and provides this information. Template/templateUrl contains the HTML representation. maybe in a distinct file or inline. Style/StyleUrls contains the style for the template. maybe in a distinct file or inline. The entire code is also contained in a component class.
