Strategy for upgrading to major versions of singleton libraries

[darktasevski]

We should expect React 19 sometime this year or next year, which made me wonder about upgrading the major version of some core library in Module Federation. Are there any strategies to make this upgrade easier, or is the only solution to upgrade and deploy all modules simultaneously?

Usually react is backward compatible as long as older version doesnt use newer ones apis etc.

You can look at our framework capbilities to see how we handle different frameworks as a single app.

In the past what i have done is just make adapter that mounts to a ref so i just mount another app onto a ref till everyone can update.

You can also assign them a different share scope. That will allow multiple singletons to exist
