Understanding Router State in Angular 7

Angular 7 (aka Angular 2) is a comprehensive framework for building client-side applications. It offers a range of tools and features that can help developers build better web applications. One such feature is the angular router state, which provides the ability to pass data through the angular router and use it to create dynamic routing. In this article, we will discuss the basics of the angular router state and how to pass data through it.

What Is Router State?

Router state refers to the state of the current application in the navigation stack. It is responsible for keeping track of the application’s current location within the stack. In other words, it allows the router to know which page the user is currently on and has access to the data associated with that page. This means that when the user navigates from one page to another, the router state updates itself so as to remember the data associated with the page before.

How Does the Router State Work?

The router state works by keeping an internal representation of the application state in the form of a tree-like structure. Each node of this tree represents a single page within the application. When the user navigates from one page to another, the router state updates itself accordingly. This way, the router can determine which page the user is currently on, and can access the corresponding data.

How to Pass Data Through the Router State?

To pass data through the router state, you need to do two things: first, you need to define routes and set the corresponding parameters for those routes. Second, you need to configure the router to expect those parameters when it is navigating between pages. To set the route parameters, you can use the “params” attribute of the router configuration object.

Once you’ve set the route parameters, you can use the router to access those parameters when navigating between pages. You can do this using the “get()” method of the router service. This method takes the parameter name as its argument and returns the value of that parameter. Once you have the value of the parameter, you can use it to store or retrieve data from the application state.

Conclusion

In this article, we discussed the basics of router state in Angular 7 and how to pass data through it. Understanding and knowing how to use the router state can help you create dynamic applications that can be easily adapted to changing user needs. Hopefully, this article has provided you with some insights into how to use the router state in your applications.
