PR submitted to get the ball rolling.

Would be perfect if you already get React 18.3.3 in package.json - in 18.3.3 they added deprecation warnings for 19

[melloware]

weird when i run npm outdated is says 18.3.1 is the latest there is no 18.3.3?

[sja-cslab]

You're correct it was 18.3.1 indeed. Just updated my local package and got wrong line ;)

Now npx codemod@latest react/19/migration-recipe and see the magic happen 😄

[melloware]

Testing now 😄

If you did not see, they got a guide for upgrading

@melloware After playing around a bit it seems that PrimeReact is currently React 19 compatible (almost).
I get deprecation warnings here and there about element.props.ref which needs to get replaced by element.ref.

What's not yet implemented in React 19 RC is the deprecation of forwardRef they're going to remove it in future so you can always use it as a property. They're going to release a codemod for this. If we're lucky that can handle the code.

The currently released codemods does not change any code in PrimeReact so far.

I think we are in good shape my PR only clarifies it for build tools that 19 is OK to use with PR.

[sja-cslab]

Are you sure 10.7 is a good milestone? React 19 is RC currently and as far as I know, there is no official timeline for the final version. How's the timeline for 10.7?

[melloware]

i think its harmless to add as its just adding this really as a hint to build tools
