How to update Angular core in Ionic#

If you are working on an Ionic project that uses Angular, it is important to keep the Angular core up-to-date to take advantage of the latest features and bug fixes. Here is how you can update Angular core in Ionic:

Method 1: Using the Angular CLI#

The easiest way to update Angular core in Ionic is to use the Angular CLI. Here are the steps:

1. Run the following command in your terminal to update the Angular CLI to the latest version:

$ npm uninstall -g angular-cli
$ npm cache clean --force
$ npm install -g @angular/cli

1. Update the Angular core by running the following command:

$ ng update @angular/core

1. If you have other Angular packages installed, you can update them using the same command:

$ ng update

1. If you encounter any errors during the update process, you can use the --force flag to force the update:

$ ng update @angular/core --force

Method 2: Manually updating the package.json file#

If you prefer to update the Angular core manually, you can do so by updating the package.json file. Here are the steps:

1. Open your project's package.json file and find the dependencies object.
2. Locate the @angular/core dependency and change its version number to the latest version.

"dependencies": {
    "@angular/core": "^12.0.0"
}

1. Save the file and run the following command to install the latest version of Angular core:

$ npm install

Using either of these methods, you should be able to update Angular core in Ionic without any issues.
