Example 1

This is a basic example of the "ng update" command. Use the following command to update the current Angular application and its dependencies −

ng update

Once the above command runs successfully, it will display the following output in your terminal:

Using package manager: npm
Collecting installed dependencies...
Found 21 dependencies.
    We analyzed your package.json, there are some packages to update:

      Name                               Version                  Command to update
     --------------------------------------------------------------------------------
      @angular/cli                       19.2.3 -> 19.2.4         ng update @angular/cli
      @angular/core                      19.2.2 -> 19.2.3         ng update @angular/core

    There might be additional packages which don't provide 'ng update' capabilities that are outdated.     
    You can update the additional packages by running the update command of your package manager.

Example 2

In the following example, we are performing a basic update to the current stable release of the core framework and CLI by running the command below −

ng update @angular/cli @angular/core

The following is the output:

The installed Angular CLI version is outdated.
Installing a temporary Angular CLI versioned 19.2.4 to perform the update.
