Angular Concepts

Angular Development – A Comprehensive Picture

Angular that is popularly known for creating smooth single-page applications, is a JS-based open-source front-end web framework. It is maintained by Google & a network of individuals and enterprises to eradicate the high-end severe issues encountered while creating a single page application. Angular is a versatile, organized, powerful MVC framework for creating a rich client-side application. Hence it also improves the scalability as the project grows. Angular is one such technology that is a must have for any software product development company that wants to develop scalable web app solutions.

Angular Concepts:-

Angular Lifecycle Hooks:

In Angular, every component has a life-cycle, a number of different stages it goes through. The 8 different stages in the component lifecycle are called LifeCycle Hook. Wherein, a constructor is the best place to inject the dependencies into the component. On executing the constructor, Angular executes its lifecycle hook method in a definite order.

Most Used Lifecycle Hooks in Angular

ngOnChanges() :

The first lifecycle hook is ngOnChanges (), which is called after a bound input property change. Angular reckons the first-class initialization after a data property change and this becomes the reason why ngOnlnit hook is not called first.  Hence in ngOnChanges(), hooks get called once the data property changes occur. The hook is specifically called whenever the constructor is called and when the change in the property inside the component occurs.

ngOnInit() :

Right after calling the ngOnChanges hook, the second hook to be called in is ngOnInit(). The ngOnlnit() is called only once, to boot the component, and to set, and display the component input properties. It also signals the activation of the created component which makes ngOnlnit() an important hook in Angular. Owning the fact of being called once, this hook helps for extracting data from external sources like servers and APIs.

ngOnDestroy() :

The last Angular Lifecycle hook is ngOnDestroy() which is being called just before the component is removed from DOM. It cleans up the components right from detaching event handlers to unsubscribing from observables.
