Angular 6 to Angular 7 Application Migration

Angular is a popular web application framework developed and maintained by Google. With the release of Angular 7, many developers are looking to migrate their existing Angular 6 applications to the latest version. In this article, we will discuss the steps for upgrading an Angular 6 application to Angular 7.

Step 1: Update Angular CLI

The first step in migrating an Angular 6 application to Angular 7 is to update the Angular CLI. You can do this by running the following commands in your terminal:

    
      npm uninstall -g @angular/cli
      npm install -g @angular/cli@7
    
  

Step 2: Update Angular Core and Dependencies

Next, you’ll need to update the Angular core and its dependencies to the latest version. You can do this by running the following command in your terminal:

    
      ng update @angular/core @angular/cli
    
  

Step 3: Update RxJS and Other Dependencies

After updating the Angular core, you’ll also need to update RxJS and other dependencies to their latest versions. You can do this by running the following commands in your terminal:

    
      ng update rxjs
      npm install
    
  

Step 4: Update Angular Material and Other Third-Party Libraries

If your Angular 6 application uses Angular Material or other third-party libraries, you’ll need to update them to their latest versions compatible with Angular 7. You can do this by running the following commands in your terminal:

    
      ng update @angular/material
      npm install
    
  

Step 5: Test and Fix Compatibility Issues

Once you’ve updated all the necessary dependencies, it’s time to test your application and fix any compatibility issues that may have arisen during the migration process. This may involve updating deprecated APIs, refactoring code, or resolving any breaking changes introduced in Angular 7.

Step 6: Update Angular 6 Syntax to Angular 7

Finally, you’ll need to update any Angular 6-specific syntax and features to their Angular 7 equivalents. This may involve adopting new features introduced in Angular 7, such as the new CLI prompts, virtual scrolling, and drag-and-drop capabilities.

Conclusion

Upgrading from Angular 6 to Angular 7 can be a smooth process if you follow the necessary steps and keep an eye out for any compatibility issues. By updating the Angular CLI, core, dependencies, third-party libraries, and addressing any breaking changes, you can ensure that your Angular 6 application is ready for the latest innovations and improvements introduced in Angular 7.
