3 Methods to Check the Angular Version

Whether you’re debugging an issue or preparing for an upgrade, knowing your Angular version is essential. This quick guide walks you through three simple methods to check the Angular version of your project. By the end, you’ll have the tools to identify it quickly and accurately.

1. Check Using the Angular CLI

The Angular CLI provides a straightforward way to check your project’s version:

1. Open a terminal.
2. Navigate to the root directory of your Angular project.
3. Run the following command:

   ng version

This displays detailed information, including the Angular version, CLI version, and dependencies.

When to Use This Method

Use the CLI if you’re working actively on the project or troubleshooting locally. It’s quick and reliable.

2. Inspect the package.json File

Your package.json file stores version information for Angular and its dependencies. Here’s how to find it:

1. Open the package.json file in your project directory.
2. Look for @angular/core under the dependencies section:

   {
     ""dependencies"": {
       ""@angular/core"": ""^15.2.0""
     }
   }

The number after @angular/core (e.g., 15.2.0) is your Angular version.

When to Use This Method

This is helpful when you don’t have the CLI installed or need to verify the version remotely (e.g., through version control).

3. Use the Browser Console

If the project is running in the browser, you can inspect the Angular version directly from the console:

1. Open the browser’s developer tools (usually F12 or right-click → Inspect).
2. Navigate to the ""Console"" tab.
3. Type and run the following command:

   ng.probe(document.body).injector.get(ng.coreTokens.VERSION).full

This will output the Angular version currently in use.

When to Use This Method

This method is ideal when accessing a deployed Angular application where you don’t have access to the source files or CLI.
