Angular is a front-end framework used to design and bring together functionalities of advanced codes into creating the most advanced and competent single-page applications on the web. Simply put, it allows developers to create rich internet applications using HTML as the template language.

A front-end framework as we all know makes it easy to put together apps in single-page apps or creating apps in general. From things as simple as creating a website, the developer needs different things to interact with each other, like JavaScript, DOMs and there is a lot of complicated back and forth that needs to happen, which means a lot of code needs to be written for these to come together and render a function. However, this becomes complex when creating a highly complex application making the codes longer, heavier to process, and a higher chance of errors. The challenges arise from the fact that these complex codes are not only difficult to bring together but are also difficult to maintain to makes sure they follow are design principles and that different parts of the applications and codes are using the same drive principles. This was all very complex to achieve in HTML and that is where the front-end frameworks come into their own.

Our biggest insurance client came up with a requirement to implement the above- What front-end to is to provide a set singular approach for developing a website or app. This means that the one page, that the end consumer can, is connecting in the back to all the functionalities into that one page making the life of end-user easy. Angular is one of the most popular frontends developed back in 2001 and was called AngularJS, Current version of Angular is famous as it has two specific approaches that have done well in delivering desired results amongst the developers.

Angular Application

Therefore, to put it technically, Angular is a web platform from Google for building mobile and desktop web applications. It creates some of the most competent and advanced single-page apps using HTML and Typescript. At the core, Angular is an application design framework and development platform. It has an open-source framework coded in Typescript and is run by individuals and corporations with Angular's core team at Google. The same team also created the AngularJS.

All web pages are a sum of their components, so a framework that can bring together different components into a single framework makes life easy for coders and this is the key strength of Angular. The app bar, the main page, and content with the various widgets in it and each one of the separate components, as in each of them have a different HTML behind the template, rendering the data or output or the rich internet application as desired to work. What Angular does it, it takes them and puts an approach around that to make creating websites easy. It does the data binding between the template of the HTML and the data that is trying to render, as in the eventual function or the outcome and that who these apps work. So, the more a frontend framework can couple modules and do all the heavy lifting between them automatically.

Angular does this in two ways, first one is read-only and the second way allows users to modify the data and the framework automatically takes care of binding, like user don't have to worry about connecting the right documents, getting the values out, these kinds of hitherto complex tasks are automatically taken care of by Angular. As most developers know, what they need is being able to use components with others or in isolation for making highly complex single-page apps. What makes the framework so successful is loose coupling and high cohesion within the modules of the application. The advantage of having components is that while it is an island of logic and function by itself it is also able to easily team up and communicate with other components to give the developer the capabilities needed for developing the application.

At its heart is Typescript, which helps in creating a front end with components that define views, which are existing sets of screen elements that Angular chooses from to create the desired single-page apps. The advantage with Angular is that while some part of the code is static, the other part is open for modification in code and then runs the functionality in the larger superset of JS codes thus rendering the app or functionality possible. It does by implementing core and optional functionality into your apps as a set of importable Typescript libraries.

One of the great advantages of Angular is its client-side routing capability. As in, for requests that require the browser to load templates and designs as the users go from the page-to-page, are inbuilt into the Angular and it takes care of rendering those requests. It connects back to the server when new data is needed from the server to render a new component. The second is called the server-side routing where every click on the components of the webpage is sourced from a remote server.

Lastly, probably the strongest point of Angular is the dependency injection, this goes into the testing the units of the application being developed. So, for testers, who are developing different components, the heart is the ability of the components to talk to each other and pass on the relevant information and data. When dependency injection does is, when a developer needs to test a new component in isolation, it can render mock tests for conduct mock data simulating the original data, that will be eventually plugged into the front end for a display to the end client.

In summary, Angular is terrific because you can develop high complex apps, by simply managing pre-written modules and test at the same time without having to hook up the component in design to all other the modules. This gives the developers the freedom to develop high quality and complex web applications in single-page apps.
