hey @chanan, this is a hydration warning from React. This is most probably because of your browser extensions injecting scripts into the HTML Document before React could hydrate the server rendered document. Check out in incognito, the warning should disappear

iwfan · 2022-01-07T14:02:12Z

Hi @chanan, You can also add suppressHydrationWarning in the root.tsx to suppress this warning.

export default function App() {
  return (
-    <html lang='en'>
+    <html lang='en' suppressHydrationWarning={true}>
      <head>
  ...

kentcdodds · 2022-01-12T15:18:57Z

I'd strongly recommend against suppressing all warnings like this. It could silence actual problems. If it were me, I would disable this extension until this issue has been resolved on the extension author's side.

joanofdart · 2022-01-19T21:02:44Z

Hey all, removed react-dev-tools but I still get the warning 😢 and I don't want to supress them all as suggested by @kentcdodds

kentcdodds · 2022-01-19T21:38:43Z

@joanofdart, I don't think react devtools causes this warning. Are you sure it's not another extension that's causing it? It could also be a third party library that's modifying the DOM before React hydrates the app.

joanofdart · 2022-01-19T22:54:29Z

@kentcdodds ill disable them all and check which one is causing this 😄 thanks for the quick response tho!

slowselfip · 2022-01-22T06:49:17Z

In my case it was Apollo Client Devtools v4.0.0. Disabling it made the error message disappear, enabling it made it re-appear.

edzis · 2022-01-26T21:26:22Z

For me it was "Google Analytics Opt-out Add-on (by Google)" - https://chrome.google.com/webstore/detail/google-analytics-opt-out/fllaojicojecljbmefodhfapmkghcbnh?hl=en

vojty · 2022-02-02T12:41:38Z

For me, it's ThreeJS Developer Tools extension for Chrome https://chrome.google.com/webstore/detail/threejs-developer-tools/ebpnegggocnnhleeicgljbedjkganaek

Elijah-trillionz · 2022-03-16T12:40:02Z

In my case, it's the video.js library and I need it

kush-daga · 2022-03-22T13:52:48Z

I also receive this warning if I try to add a third-party script in the Remix app using <script> tag in the body. Is there a better way to go about this, loading third-party scripts? Maybe I missed it in the docs.

github-actions · 2022-04-07T16:00:12Z

🤖 Hello there,

We just published version v1.3.5 which involves this issue. If you'd like to take it for a test run please try it out and let us know what you think!

Thanks!

corgipower · 2022-04-24T20:00:52Z

I'm getting this as well, on remix 1.4.1.
For me, it's coming from a disable autoplay extension, but I don't get this warning in apps built with other frameworks.

eric-burel · 2022-05-04T14:58:32Z

Hi, why is this issue closed? I understand that the issue is probably not on Remix yet it's expected to have extensions injecting scripts in apps, I am not sure why we get this warning. Could it be at least more explicit (for instance having a bit more info about the script to quickly tell which one is responsibile)?

kentcdodds · 2022-05-04T15:11:03Z

The warning you see is coming from React, not Remix. So there's literally nothing Remix can do for you here. You'll want to open an issue on React if you want to improve the error message.

arnaudambro · 2022-05-15T18:46:59Z

Hello !
In my case, I'm not seeing it with Chrome and Firefox, but with Safari I do, where I installed the extension Google Analytics Opt-out Browser add-on. If I disable that extension, no more warning.

Disabling the Apollo Client Devtools extension fixed the issue for me. 👍

This plugin was also the cause of the issue for me.

Just reporting seeing this issue with Adobe Acrobat: PDF edit, convert, sign tools Chrome extension

heydavee · 2023-04-15T16:27:02Z

For me it was a coupon extension. Never would have thought about it.
To my german friends: Try to disable the Shoop extension.

I have the same problem with newrelic.getBrowserTimingHeader, Newrelic browser agent

amodanov · 2023-06-14T13:18:17Z

I am experiencing an issue where the __staticRouterHydrationData is not present in the final server-rendered version of my application, despite being generated during the server-side rendering process.

<div id="react-app">
    <div class="page">.......</div>
    <script nonce="........">
        window.__staticRouterHydrationData = JSON.parse("{\"loaderData\":{\"0\":null,\"0-0\":null},\"actionData\":null,\"errors\":null}");
    </script>
</div>

This script tag, specifically for __staticRouterHydrationData, is available when generated on the server. However, it mysteriously disappears in the final version.

Has anyone else encountered a similar problem, or perhaps could provide insight on why this might be happening?

gavriguy · 2023-06-19T13:49:02Z

In my case, it's the video.js library and I need it

Hi @Elijah-trillionz did you manage to run videojs on remix without getting those errors?

kiliman · 2023-06-19T14:25:24Z

@gavriguy when trying to import a package that doesn't support SSR, the typical solution is to re-export the component from a *.client.tsx file. Then wrap in <ClientOnly> from remix-utils.

// components/video.js.client.tsx
import videojs 'video.js'

export const VideoJS = (props) => {
  // from https://videojs.com/guides/react/
  // ...
}
export default VideoJS

// routes/video.tsx
import VideoJS from '~/components/video.js.client'
import { ClientOnly } from 'remix-utils'

export default Component() {
  return (
    <ClientOnly>
      {() => <VideoJS />
    </ClientOnly>
  )
}

gavriguy · 2023-06-19T14:50:28Z

Hi @kiliman thanks for your answer. That's exactly what I did but I still get errors:

kiliman · 2023-06-19T15:04:02Z

@gavriguy Hmm.. Here's a working ⚡️stackblitz

https://stackblitz.com/edit/remix-run-remix-c7dobq?file=app%2Froutes%2F_index.tsx

gavriguy · 2023-06-19T15:25:14Z

Thanks it is working :) but there are still errors in the console log:

kiliman · 2023-06-19T15:47:43Z

Hydration issues occur when code outside of your app modifies the DOM. This is typically caused by browser extensions. There are workarounds like https://github.com/kiliman/remix-hydration-fix. The next version of React will minimize these hydration errors. You can verify by installing react@canary.

gavriguy · 2023-06-19T16:03:36Z

Thanks for you help much appreciated.

I gave your solution a try and it works without any errors. Cheers :)

It seems that I have resolved my issue by using suppressHydrationWarning, but I'm unsure whether this is a good solution or simply a workaround.

Is this behavior expected and should it work correctly in React version 17?

<React.Fragment>
    <Provider store={store}>
        <RouterProvider router={router} fallbackElement={null} />
    </Provider>

    <SuppressScriptHydrationWarning />
</React.Fragment>

export const SuppressScriptHydrationWarning = () => {
    const [isClient, setIsClient] = useState(false);

    useEffect(() => {
        setIsClient(true);
    }, []);

    return isClient ? null : <script suppressHydrationWarning={ true } />;
};

Mihai-github · 2023-09-07T07:08:52Z

Hey, I have a html template that I have to move to Remix.js witch includes many js files, from libraries like bootstrap to custom js, but when I put them into the public folder and try to include them into the root.tsx file I see in the server console errors regarding route not found plus on the client hydration issues and also the ui for a second has a flicker but the js is not working...

Is this something that is not supported or I don't know?
