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 then15-16Congratulations, 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. Hope this Guide to Angular 16 Upgrade helps you to get your latest version. For more blogs like this, stay tuned to Tuvoc Technologies.
