Deprecated browserlist

    Creating a new ionic project, an error occurred while running npm i command. I've got a warning indicating "deprecated browserlist@2.11.3 (3.0 config used in other tools)" and "hoek@2.16.3 (The major version is no longer supported)". I am using ionic 3.19.1.

I would like to know if updating to ionic 4.x is the only solution and, if so, what about the projects I created before with the 3.19 version? Are they going to work all right? How many changes should I make on them?
Thank you very much!


It’s confusing, but Ionic doesn’t have a monolithic version number. At a minimum, you need to think of the CLI and the framework as totally disassociated. Theoretically (meaning “Ionic says this is supposed to work”), if you have created a project with version X of the CLI, then any CLI version >=X should be able to build it.

So, it sounds like you’re asking “can I upgrade the CLI without upgrading the framework in my old projects?”, and the answer is (supposed to be) “yes”.

Upgrading the framework is a completely different topic, and generally a lot more involved. In most cases, you are best off creating a new project from scratch and parachuting your old source into it.

    Well, then. If upgrading is the only solution, I'll pray everything works fine in my previous projects. Thank you very much for your clear explanation.
