Question
Answer and Explanation
To validate the version of Angular you are using, you have several options. Here are the most common methods:
1. Using the Angular CLI (Command Line Interface):
- The Angular CLI is the most straightforward way to check your Angular version. Open your terminal or command prompt and navigate to your Angular project's root directory. Then, execute the following command:
ng version
- This command will output the Angular CLI version, as well as the versions of other Angular packages installed in your project, such as @angular/core, @angular/router, and others.
2. Checking the `package.json` File:
- Your project's `package.json` file contains a list of all the project's dependencies and their versions. You can manually inspect this file to identify your Angular version.
- Look for dependencies that start with "@angular/". The version numbers listed next to these dependencies (e.g. "@angular/core": "^16.0.0") indicate your installed Angular versions.
- The package.json file is typically found at the root of your project directory.
3. Checking through the Application's Console:
- Within an Angular application, you can programmatically access the Angular core version. Open the browser's developer console and paste the following JavaScript code snippet in the console:
//Use only in Angular Application
ng.probe(document.querySelector('body')).injector.get(ng.coreTokens.VERSION).full
- This code will retrieve the current Angular core version and output it in the browser's console. This method is especially useful for quickly verifying the version in a running application.
4. Using the Angular DevTools Extension (Browser Extension):
- The Angular DevTools browser extension is a very useful tool to inspect the components and versions of your Angular app. After installing it in your browser, navigate to your Angular app and open the DevTools. Within the Angular tab, you should find information about Angular versions used by the application.
These methods will help you reliably validate the version of Angular you are using in your project.
