Hey @gkiely - I'd like to work on this issue
I've looked into it and this happen only with StrictMode enabled.
Does this work in React 18?
Yep, React with 18 useEffect runs everytime if the file is updated
Can reproduce with the provided repro and also next@15.0.0-canary.76
. I also double checked by using breakpoints to ensure it's not just console.log
being incorrectly silenced.
In prior versions of react, saving a file will trigger the components useEffect hooks to run. This does not work for react 19. This applies to both @vitejs/plugin-react-swc and @vitejs/plugin-react

Notes: I previously opened a ticket here but it is perhaps an issue with react 19: https://github.com/vitejs/vite-plugin-react/issues/335
