How to Migrate from AngularJS to Angular - A Step-by-Step Guide

So, you’ve decided to upgrade from AngularJS to Angular. It’s a big step, but definitely worth it for future-proofing your tech stack.
In This Video, You'll Learn:
- Migration Approaches: Understand the two main migration approaches: revolution and evolution. Find out why the evolutionary approach is recommended for larger projects.
- Evolutionary Approach Explained: Learn how to migrate your application gradually, allowing AngularJS and Angular code to coexist. Discover tools like ngUpgrade that make this possible.
- Step-by-Step Migration Plan: Get a detailed, step-by-step plan to guide you through the migration process.
Step-by-Step Migration Plan:
- Prepare with TypeScript: Set up TypeScript and integrate it with your existing JavaScript code using the @types/angular package.
- Create a New Build: Use Angular CLI to build your AngularJS app, copying files into the new Angular project folder.
- Implement Hybrid Update: Use ngUpgrade to run AngularJS and Angular code side by side.
- Transfer Services and Components: Downgrade components to make newer parts available within the AngularJS segment.
- Refactor Module Configurations: Adapt AngularJS module configuration files to match Angular’s structure.
- Update Routing: Use UI-Router to handle routing in a hybrid environment.
Refactor Dependencies: Replace factories with services in Angular and align dependencies with Angular’s architecture.
- Thorough Testing: Test extensively to ensure all parts of the app function correctly in the new framework.
