Angular Tutorial

Angular is a popular open-source Typescript framework created by Google for developing web applications. Front-end developers use frameworks like Angular or React to present and manipulate data efficiently and dynamically. Angular has been actively updated and become has more and more efficient with time, especially since the time the core functionality was moved to different modules.

Newly added angular CLI & with the help of this command-line interface, we can install the required packages that facilitate creation & make the complex-structured code into a modular form that can be easy to manage and provide reusable components.

Features of Angular

• It uses components and directives. Components are the directives with a template.
• It is written in Microsoft’s TypeScript language, which is a superset of ECMAScript 6 (ES6).
• Angular is supported by all the popular mobile browsers.
• Properties enclosed in “()” and “[]” are used to bind data between the view and the model.
• It provides support for TypeScript and JavaScript.
• Angular uses @Route Config{(…)} for routing configuration.
• It has a better structure compared to AngularJS, easier to create and maintain for large applications but behind AngularJS in the case of small applications.
• It comes with the Angular CLI tool.

Why to Learn Angular?

Angular is a great framework and is very beneficial because of its features, structure, ecosystem, and support. Here’s why:

• Community support: It is developed and maintained by Google. Also, it is based on typescript which is created by Microsoft. Hence it has a big community support.
• Free of Cost: Since it is an open-source language, therefore developers are allowed to use its components and all methods for free.
• Easy to learn: It has a big community and many resources are available
• TypeScript: Angular is a typescript-based framework which is a statically typed superset of javascript.
• Angular CLI: Angular CLI helps in simplification processes like creating, building, and deploying the application.
• Cross-Platform Development: With NativeScript it is used to build dynamic mobile-based applications.

Applications of Angular

• Single-Page Applications (SPAs): Angular is particularly well-suited for building SPAs, where a single webpage is created and content is dynamically updated as the user interacts.
• Real-Time Applications: Angular is most used in real-time applications, such as chat applications, weather and forecasting, and live tracking systems, where immediate updates are essential.
• Enterprise Applications: Angular is commonly used for developing large-scale enterprise applications. Its modular architecture, dependency injection, and TypeScript support make it suitable for building complex and maintainable applications.
• Content Management Systems (CMS): Angular can be used to build custom content management systems, providing a dynamic and responsive user interface for managing content.
• E-commerce Websites: Angular’s two-way data binding and dynamic features make it suitable for building interactive e-commerce websites with real-time updates and user interactions.
• Dashboards and Analytics Tools: Angular is used to create interactive dashboards and analytics tools, it helps in data visualization and crucial real-time updates.
• Cross-Platform Mobile Apps: With frameworks like Ionic or NativeScript, Angular is used to build cross-platform mobile applications for iOS and Android operating systems.
• Social Media Applications: Angular is used widely for building social media applications with dynamic content rendering, and interactive features.
