Upgrade to Angular 16: Steps to follow

Step-1

First, update your npm packages. Most Angular projects use npm (Node Package Manager) to manage their packages.

Use the following command to upgrade to the most recent version of npm:

npm install -g npm@latest

Before upgrading your application, ensure that you are using a supported version of node.js.

Node.js versions 16 and 18 are supported by Angular v16.

Before upgrading your application, ensure that you are using a supported version of TypeScript.

TypeScript version 4.9.3 or later is supported by Angular v16.

Step 2 (update angular cli, core, and cdk)

To get Angular 16, you must first upgrade @angular/cli and @angular/core.

It is not possible to update multiple major versions of ‘@angular/cli’ at the same time. Please migrate each major version separately.

To update to the current ’15.x’ version of ‘@angular/cli’, run ‘ng update @angular/cli@15’ in your workspace directory.

The Angular CLI should appear at 16. x.x.

If you installed @angular/cli successfully, you can skip this step. However, if you run into any problems, please continue with this step.

angular/cli should be removed:

npm uninstall -g @angular/cli

Install Angular CLI:

npm install -g @angular/cli
ng version

Step-3

Remove any unnecessary code from the test.ts if it is not automatically removed.

Step-4

Remove the node_modules and the package-lock.json thenCongratulations, you have just installed the most recent version of angular.

Final Words

Over the years, Angular has become a powerful tool for building excellent web and mobile applications. The team behind Angular at Google is always working to make things more exciting for developers.
