React 19 compatibility #2934

vladmoroz · 2024-06-04T11:06:54Z

Access ref from props when possible
Remove propTypes usage
Replace our ComponentPropsWithoutRef type with the built-in React type

Prop types have been deprecated for a while and are now completely removed

Using TypeScript already handles this

packages/react/progress/src/Progress.tsx

+    }
+
    const max = isValidMaxNumber(maxProp) ? maxProp : DEFAULT_MAX;
+
+    if (valueProp !== null && !isValidValueNumber(valueProp, max)) {
+      console.error(getInvalidValueError(`${valueProp}`, 'Progress'));
+    }
+


Relocated the logic from propTypes that TypeScript can't help with

-    }

 /* -----------------------------------------------------------------------------------------------*/

-// Split this out for clearer readability of the error message.

Ref access instance 1 of 2

A bit messy checking for the getter presence, but a naïve attempt to access either element.props.ref or element.ref directly like in #2811 yields a warning pre React 19

packages/react/primitive/src/Primitive.tsx

-// Temporary while we await merge of this fix:

-type PropsWithoutRef<P> = P extends any ? ('ref' extends keyof P ? Pick<P, Exclude<keyof P, 'ref'>> : P) : P;
-type ComponentPropsWithoutRef<T extends React.ElementType> = PropsWithoutRef<
-  React.ComponentProps<T>
->;
-
-type Primitives = { [E in typeof NODES[number]]: PrimitiveForwardRefComponent<E> };


This stuff is integrated into @types/react

Setting the ref property has always yielded a type error, just didn't break the build before

I wonder what's the future of the Slot component as React considers cloneElement a legacy api. 🤔

We'll see—I haven't seen a good alternative there, and "legacy" doesn't mean it's deprecated yet. I think it will stay around for a while.

🤯

Should we extract this to a utility and reuse in other places instead of having the duplicated code?

Would have to be a separate package—I'd say we can keep it like this for now and extract it later if there's 3+ uses. I think two copy-pastes is OK for now.

Same method as before, let's extract to a utility.

It looks like we could save bundle size here. How about going with

return React.version.split('.')[0] >= '19' ? element.props.ref : element.ref;

or

return element.props.propertyIsEnumerable('ref') ? element.props.ref : element.ref;

for this method? It seems to pass the tests.
