I have a use case to migrate a large angularjs application and I want to start by doing this process in a small application first. So for that reason, I've took the tour of heroes angularjs webapp and I started to add angular to it ( by creating a new project with the angular-cli ) and then adding the NgUpgrade module.
The problem that I have now is that the angularjs webapp runs pretty well inside the angular 8 application but the components that belong to angular 8 they are not rendered.
I have the impression that my angular components are not bootstrapped since I've bootsraped manually angularjs but I'm not sure ... when I add explicitly the bootstrap property inside the @NgModules it works only for the angular components but not for angularjs (it makes sense ). So I was thinking maybe I have to upgrade the angularjs components or downgrade the newest angular components but I don't think so.
Here you will find the git repository with the code. Below more information related to my project:
- angular version: 8.2.8
- angularJS version: 1.6.10
- angular-cli: 8.3.6
