What is CanActivateChild() Method in angular routes with details understanding and examples

Hello Guys,

In this blog we are going to learn about child routes using auth guard with CanActivateChild() with details understanding and examples.

CanActivateChild() allows you to guard child routes in a similar way to CanActivate for guarding individual routes.

CanActivateChild() is basically used to protect child routes inside the application from unauthorized users. This means if users don't have access then they can't access child routes.

When every you creating canActivateChild, in that we are creating guards that execute before access of child routes.

CanActivateChild() method normally takes two parameters : route and state. The route parameter represents the child route being activated, while the state parameter represents the current router state. The CanActivateChild() method must return a boolean value indicating whether the user has permission to access the child method.

For Examples :

Authenticating users with a service named authService, our guard, "AuthGuard," uses CanActivateChild to check if the user is authenticated. This method, canActivateChild, will pass if the user is authenticated, allowing access to the child route. If the user is not authenticated, the method will utilize a UrlTree object to redirect the user to the login page.

To implement AuthGuard in safeguarding child routes, you need to include it into the canActivateChild feature of its parent route.

Adding AuthGuard to the products route's canActivateChild property ensures that only authenticated users will be able to access the child route. The AuthGuard is executed before the activation of ProductDetailComponent in the example given.

Implementing CanActivateChild in your Angular app is a smart choice since it grants you the ability to guard your child routes and restrict unauthorized users from accessing them. This interface has a lot of power and can protect your application and your users' data. By creating guards with CanActivateChild, you can rest easy knowing that only authorized individuals will have access to protected areas.

Different between ``===`` and ``==`` operators in JavaScript

Hello Guys, In this blog we are going to learn about "===" and "==" different with details understanding and examples. JavaScript operators that you might have stumbled upon as a developer include "===", "==". JavaScript's "==" operator is commonly utilized for loose comparison purposes. It functions by converting both of the values to a common type and then comparing them for equality. Here's an example: The comparison operator "==" transforms the value of "17" from a string to a number before determining if the values match. Consequently, if both versions of the data share the same properties and values, the comparison is marked as valid and returns true. The results of the "==" operator can occasionally be surprising, including: The comparison returns true when the "==" operator converts the empty string to the number 0 and compares it to the number 0. This can result in bugs, so ...

What is the Lazy-loading in Angular and Different between Old syntax and New Syntax of Lazy-loading with examples

Hey Guys, In this blog we are going to learn about How we can use Lazy-loading in angular with examples. We are also going to learn the different syntax of lazy loading in angular . Lazy loading is used to load the specified module once the routes match. It will load the modules once use access that particular section or modules in our application. Using lazy loading will improve the performance of our application and also decrease the load time of our application. Using lazy-loading will help to reduce the bundle size of the application. Lazy -loading Old syntax in angular 7 or lower version { path: "feature", loadChildren:'./feature-module/feature-module.module#FeatureModuleModule' }, Lazy -loading new syntax in angular 8+ { path:'feature', loadChildren:() => import...

Learn About Call(), Apply() and Bind() Method in JavaScript

Hello Guys, In this blog your going to learn about CALL(), APPLY() and BIND() method in JavaScript with details understanding and examples. Invoking a function with a specific this value is possible in JavaScript through call(), apply(), and bind(). These three methods may be comparable in terms of their function, but the way they operate and handle arguments set them apart. call(), apply(), and bind() can be confusing to differentiate, so let's look at how each one differs from one another. Call() :- Method used to invoke a function with specified this value and given arguments - call(). First argument is this value, followed by any expected arguments. For instance, a case in point: Calling findNames() in this scenario, we set the this value to person, thus causing person.name to equate to this.name within the function. APPLY() :- Ahead of time, it's sometimes unclear how many arguments will be required when calling a function. In such instances, the apply() metho...
