It's odd that we see some warnings in the unit test on this PR but not when I did the React 18.3 upgrade. |
|
Indeed. Maybe they tinkered with some feature flags between 18.3 and 19 beta. |
|
If I understand correctly, many of the test warnings seem to be because of how Ariakit retrieves the ref prop, it falls back to and that yields a warning in React 19. At the same time, I assume Ariakit will stay compatible with older React versions where @diegohaz @DaniGuardiola any idea if we're planning to do anything about these warnings in Reakit? |
|
@diegohaz could Ariakit possibly use some sort of React version detection instead and use it to determine what to do, rather than this fallback system that creates warnings? |
|
That part was updated to avoid those warnings (ref: https://x.com/diegohaz/status/1780794744534163888). But apparently it's not enough? I still don't know the idiomatic way to fix that. |
|
@diegohaz @DaniGuardiola I actually tried updating to the latest Ariakit version in this branch and it seems to resolve those warnings 👍 Dani has started working on the update in #60992, and here we have one more reason to move it forward. |
|
Updated to the RC. Hoping to have some time next week to play more thoroughly with it. |

Fixed some tests, most of them were pretty straightforward. At first glance, the mobile tests seem to be failing because RN uses an old React version - we'll need a RN update to support React 19. |
|
FYI, Framer Motion will be a blocker for now. More context: #60975 |
|
React 19.0.0-rc.0. is out.
Source: https://x.com/acdlite/status/1797668537349328923 I also wonder if facebook/react#29585 could be an issue for the block editor. Potentially, it can affect block re-ordering, but it will need some testing. |
|
Seems like we'll need to wait a bit for now, re https://x.com/sophiebits/status/1801663976973209620?s=46 and https://tkdodo.eu/blog/react-19-and-suspense-a-drama-in-3-acts Happy to retry this once the release gets unblocked once more. |
|
The suspense issue doesn’t affect our codebase, so we could try the latest RC. |
|
Updated to the latest RC. We'll still need to wait for RN support: |
|
See callstack/react-native-testing-library#1698 for RN support for React 19 (hopefully H1 2025) |

A few updates as I've been experimenting with making React 19 work in the meantime:

IIRC, we can also use suspense around components loading assets on demand and defer rendering. It could help render different previews. |

Thanks for the heads up. A few updates:
Haven't done thorough testing, but it could be in a testable state at this point. Next steps: There are some failing e2e tests, we need to investigate why and fix the cause. Note: React Native is still a blocker: callstack/react-native-testing-library#1698 |
