Scott,
Yes, support for Angular is already built it. In our recent 2023 release, we updated our support to work with Angular 16 (and it should work with more recent versions too). JavaScript and TypeScript support have been significantly improved as well.
You won’t need to migrate your projects. Simply open the root folder and you should be able to start coding.
We haven’t had any users develop with Ionic that I’m aware of, and while we don’t have specific support for Ionic wizards / generation, the general support we have for JS, TS, HTML, JSON, etc. should have you covered.
MyEclipse includes a 30 day trail, we’d encourage you install it and let us know if you run into any issues.
Thanks!
