Angular 14, the newest version of Angular, brings a lot of new changes to the popular JavaScript framework. If you’re an existing Angular developer, it can be hard to navigate all these changes without guidance, which is why we’ve created this step-by-step guide to help you make the transition from Angular 13 to Angular 14 as smoothly as possible. Follow our instructions and you’ll be developing with the latest version of Angular in no time!
How do I migrate my Angular CLI app?
The process of migrating an Angular CLI app is actually quite simple. First, update your dependencies and devDependencies in package.json to the latest versions. Next, update your project’s tsconfig.json file to target ES2015. Finally, update any global typings files you may be using (such as d.ts). Once you’ve done all that, you should be good to go! Remember that these steps are not required if you’re just upgrading from Angular 13 to Angular 14. However, they will ensure compatibility with future releases of the framework.
What about ng upgrade?
If you’re using the Angular CLI, you can update your project to the new version with a single command: ng update @angular/core @angular/cli. This will automatically update your project’s dependencies and begin the migration process. You’ll need to run a build before deploying in order for any of these changes to take effect. The final step is migrating your TypeScript code.
You can find more information about this in this guide on upgrading from Angular 13 to Angular 14. In general, there should be no breaking changes when upgrading from one major release to another. That said, if you have any libraries that are lower than version 3.0, it might break if they rely on newer features introduced in later versions of Angular.
What other breaking changes do I need to worry about?
If you’re using the Ivy renderer, you don’t need to make any changes. For the rest of us, there are a few breaking changes we need to be aware of. One is that Observable objects passed into .pipe() or .subscribe() must now implement the Subject interface and return a value from next(). It also breaks down into two other important updates.
The first is that the router no longer supports parametrized routes.
The second is a change in how animations work across browsers. What this means is that if your code relies on browser specific CSS properties such as –webkit-animation then it won’t work anymore. We recommend updating your code to use transition instead which will ensure cross browser compatibility.

How do I migrate my real project?
If you’re using the Angular CLI, all you need to do is update your project’s dependency on the angular package. Just open your package.json file and change the version of the angular dependency to ^14.0.0. Once that’s done, run npm install or yarn install to get the updated dependencies.
You can then either use ng serve or ng build to build your application and start it up in the browser (ng serve will just be a little bit faster).
You’ll also want to go into src/index.html and replace any references to angular with angular2. The polyfills property should also be changed from angulartypescript to angular2typescript.
Finally, if you have any changes to services like HttpClientModule, you’ll want to make sure they are imported as well.
How do I update test code?
If you’re using Jasmine, there’s nothing new to update. However, if you’re using Protractor, you’ll need to update your configuration file and drivers. You can find more information about this in the migration guide. You can now use TypeScript 2.8 with angular and typescript@next!
For ng serve , use npm run serve –dev=false –aot=true . Read more on Stack Overflow for more details on changes to src/tsconfig.app.json when updating from Angular 13 to Angular 14. When migrating to Angular 4, make sure to upgrade your dependencies like @angular/core as well as angular2-jwt. There are three major steps involved in Angular app development. The first is starting up an Angular Development Services account, which includes purchasing time and selecting your desired level of service (in terms of hours). The second step is picking what type of app you want to develop, such as a single-page application or mobile application. The third step is hiring Angular developers who will take care of the heavy lifting.
One final tip
If you’re planning on migrating your Angular 13 app to Angular 14, there are a few things you should keep in mind. First, be sure to update your Angular Development Services and dependencies. Next, run through your app and look for any deprecated features that have been removed in Angular 14. Finally, test your app thoroughly before deploying it to production. By following these steps, you can ensure a smooth transition to the new version of Angular. For more information about Angular Development Services or Angular app development, contact us today!
