How to build custom design editor to edit adobe illustrator files

Hi all,

I want to have a custom design editor for one of my javascript-based projects. where users can import the files and can edit the contents of imported files. The user should be able to import and export files programmatically.
Also, the users should be able to create new design templates using that editor. so that the templates can be used and modified later on by other users.
Like the user can create a template with multiple layers for name, phone, and other icons and elements which can be changed by some other users later on.
The custom editor should be able to import the following file types

• .ai
• webp
• png
• jpg etc

is that possible? which one is the best option to achieve this functionality?
