How to Update the Latest Version of Angular?
Updating Angular to the latest version is crucial for maintaining security, performance, and accessing new features. Here is the process of updating Angular, ensuring a smooth transition with minimal disruptions.
Step 1: Check the Current Angular Version
Before updating, it’s important to know which version of Angular your project is currently using. You can easily check the version with the following command:
ng --version
This step helps you assess whether you need to upgrade to the latest stable version or if incremental updates are required. It also ensures you’re working with the correct environment before beginning the update.
Step 2: Update Angular CLI Globally
The Angular CLI is the tool you’ll use for managing your Angular projects. To update the global Angular CLI version, run the following command:
npm install -g @angular/cli
Updating the global Angular CLI ensures that you’re using the latest version, which can help in creating and managing Angular projects more efficiently. This step is vital because an outdated CLI may not be compatible with the newest Angular features.
Step 3: Update Angular CLI Locally
Now, update the local version of Angular CLI within your project directory by running:
npm install @angular/cli
The above command updates the Angular CLI to the latest version locally. It will ensure that the project is aligned with the latest tooling and capabilities provided by Angular.
Step 4: Run Update for Your Project
Angular CLI provides an update command that automatically handles many of the dependencies and package updates. To update your project, simply run:
ng update @angular/core @angular/cli
The above command updates the core Angular packages and Angular CLI, ensuring that your project uses the latest version and dependencies.
Step 5: Update Other Dependencies
Angular projects may have third-party dependencies that also need to be updated to ensure compatibility with the latest Angular version. Run the following to check and update these dependencies:
ng update
Here we ensured that all other packages related to Angular are compatible with the updated core packages. It will help you prevent conflicts or issues during development.
Step 6: Test the Application After the Update
Once the update is complete, run your Angular application locally and perform testing to ensure everything works as expected. Use the following command to start your application:
ng serve
Running this command ensures the update didn’t introduce any breaking changes or issues into your application.
Following these steps ensures that you can efficiently update your Angular projects while minimizing risks. By using Angular’s built-in tools and CLI commands, you can make the update process simple and take full advantage of the latest features and improvements.
