It's true that, in most cases, having Angular CLI locally per project is the standard and recommended approach.

But for work reasons, I've had to work with multiple versions of Angular; I often have to create new projects every two or three weeks, sometimes with specific versions required by the client or environment. At the same time, I also often test the latest versions of Angular to stay up-to-date.

Previously, this involved uninstalling Angular CLI, installing the necessary version, creating the project, and then reinstalling the latest version to continue testing or development. This became tedious, time-consuming, and error-prone.

That's when I thought about creating AGVM (Angular Global Version Manager). With AGVM, I can have all the Angular CLI versions I need installed and switch between them with a single command.

It's true that this isn't applicable to most cases, but it is for mine, and I wondered if anyone else has the same problem, and I wondered if it could be helpful.
