Today many companies use Angular to build websites and apps. But some still use old AngularJS. AngularJS is now outdated.

Introduction

It is slower and does not work well with new features. If you want to grow in web development, you must move to Angular. This blog will show you how to do that.

If you want to start learning, you can take an AngularJS Online Course. It helps you understand both AngularJS and Angular.

Why Migrate to Angular?

Angular is faster. It uses TypeScript which is better than JavaScript. Angular has better tools and support. It is made for mobile too. AngularJS does not work well on mobile. Angular gets regular updates. AngularJS will not get updates anymore.

Let us look at this in a table.

Feature	AngularJS	Angular
Speed	Slow	Fast
Mobile Support	No	Yes
TypeScript Support	No	Yes
Tools	Fewer	Many
Updates	None	Regular

Step 1: Learn the Basics

Start by learning TypeScript. Angular uses TypeScript. It is like JavaScript but better. Then learn Angular structure. Understand components, services, and modules. These are not in AngularJS.

You can join an Angular Certification Course to learn all these things step by step.

Step 2: Set Up Your Angular Project

You can use Angular CLI to create a project. It is a command line tool. It helps you make a project with a few simple commands.

Use this command to create a new app:

ng new my-new-app

This makes a fresh Angular app. It is clean and ready.

Step 3: Audit Your AngularJS App

Look at your old app. Write down all features. Find the parts you want to move first. Break your app into small parts. Start with easy parts.

Step 4: Use ngUpgrade

ngUpgrade helps you use AngularJS and Angular together. This way you do not need to move all at once. You can do it step by step. It is called hybrid mode. You can keep using the old app while you build the new one.

Use this command to add ngUpgrade:

npm install @angular/upgrade

Then update your code to use both frameworks.

Step 5: Move Components One by One

Now start moving parts from AngularJS to Angular. Pick one small feature. Make it in Angular. Test it. Replace the old one. Then do the same for the next one. Keep doing this until all features are moved.

Step 6: Remove AngularJS

Once all features are in Angular, remove AngularJS. This step is easy. Just delete all AngularJS code. You now have a full Angular app.

You can now enjoy fast speed and better tools.

Extra Tips

Use Git. It helps you save code changes.
Test everything before removing old code.
Keep backup of old code.
Ask experts if you get stuck.
