NextJS 15 unmet peer react@"^16.11.0 || ^17.0.0 || ^18.0.0": found 19.0.0-rc-65a56d0e-20241020

Bug

The supported React peer dep version range for v2.2.5 does not include React 19.0.0-rc
The main branch does, however, no new versions were released in the previous 5 months.

The dependency use-sync-external-store has a similar issue

swr 2.2.5
nextjs 15.0.0

@Yonom try --force option

@promer94 not a "good first issue", the fix has already landed in main 5 months ago, it just needs to be deployed to npm

[TomerHeber]

Can this be deployed?
I'm "forced" to use --force with nextjs 15.

Thanks!

you can use this in package.json (make sure to use the react version you use in your project, my "19.0.0-rc-66855b96-20241106"):

  "overrides": {
    "html-react-parser": {
      "react": "19.0.0-rc-66855b96-20241106"
    },
    "swr": {
      "react": "19.0.0-rc-66855b96-20241106"
    }
  },

    }
  },

ah, nice it worked for me. For pnpm i ended up with:

{
  "pnpm": {
    "overrides": {
      "swr>react": "19.0.0-rc.1",
    },
  }
}

When can we expect a new release, that's compatible with React 19?

[Katyi]

What version nextjs I should use for avoid this issue?

you can use nextjs 14

[dgtllion]

now react 19 is out is it possible to update swr?

We've just released v2.3.0, which supports React 19, so I think this issue would be fixed.
