Hi,

I am new to Angular js and I was trying to find out proven ways to upgrade an existing Angular 1 app to Angular 4.
What I wish to do is to be able to run the angular 1 and angular 4 components together since I do not want to migrate all at once and proceed gradually.
It will be a great help if some could point me in the right direction.

Thanks.

What I have tried:

I have tried googling a few times but only one relevant result comes up ng-book.com or something. Not very helpful.
They do not seem to be saying anything about the hybrid application.

What does the angular team website say?

Not much. But I have looked at this https://vsavkin.com/migrating-angular-1-applications-to-angular-2-in-5-simple-steps-40621800a25b, it seems good but it does not say anything about being able to run the angular 1 and 4 components together. (Sorry to not have mentioned that in the question I'll update it.)

Solution 1

If your project is not very complex you may do it incrementally. Bootstrap and use both AngularJS and Angular 6 running the two frameworks side by side and port components from AngularJS to Angular one by one.

Take a look at this official article and this Upgrade module
