Angular Route Guard: Implement Route Guard in Angular 10

Angular route guard allows us to grant or remove access to certain parts of the navigation. Another route guard, the CanDeactivate guard, even enable you to prevent a user from accidentally leaving a component with unsaved changes.

Why we need Angular guards

To prevent unauthorized access to certain parts of our navigation, use route guards in Angular.

The client-side route guards like this are not meant to be a security feature. They won’t prevent a smart user from figuring out a way to get to the protected routes.

Such security should be implemented on the server-side. So you need to develop the logic for the server-side, and based on the response, we will change the routes.

Route guards are instead meant as a way to improve the UX for your apps.

Types of routing guards

Route guards in Angular can prevent users from navigating to parts of an app without authorization.

There are 4 route guards available in Angular.

  1. CanActivate: It controls if a route can be activated.
  2. CanActivateChild: It controls if children of a route can be activated.
  3. CanLoad: It controls if a route can even be loaded. This becomes useful for lazy-loaded feature modules. They won’t also load if the guard returns false.
  4. CanDeactivate: It controls if the user can leave a route. Note that this guard doesn’t prevent the user from closing the browser tab or navigating to a different address. It only prevents actions from within the application itself.

To use route guards, consider using component-less routes as this facilitates guarding child routes.

How to Create Guard Service in Angular

To create a service for your guard, type the following command.

ng generate guard your-guard-name

In your guard class, implement the guard you want to use. The following example uses CanActivate to guard the route.

In your guard class, implement the guard you want to use. The following example uses CanActivate to guard the route.export class YourGuard implements CanActivate {
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): boolean {
      // your  logic goes here
  }
}

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • Node.js
  • npm Package Manager
Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

  1. npm -v

Installing Angular CLI

  • Open Terminal/Command Prompt
  • To install Angular CLI, run the below command:
  1. npm install -g @angular/cli

installing angular CLI

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

angular CSS options

  • To leave everything to default, simply press the Enter or the Return key.
