When I run npm run build and npm start on my local machine it deploys perfectly to localhost but when I try to deploy the very same code to Vercel I get the following error:
08:28:16 Failed to compile.
08:28:16 ./pages/index.tsx:5:20
08:28:16 Type error: Cannot find module '../components/layout' or its corresponding type declarations.
It definitely seems like an issue with the Layout component, I switched around the order of the important and it always fails when trying to load the Layout component. Here's the code for the component:
import Alert from "./alert";
import Footer from "./footer";
import Meta from "./meta";
type Props = {
preview?: boolean;
children: React.ReactNode;
};
const Layout = ({ preview, children }: Props) => {
return (
<>
<Meta />
<div className="min-h-screen">
<Alert preview={preview} />
<main>{children}</main>
</div>
<Footer />
</>
);
};
export default Layout;
index.tsx line 5 looks like this import Layout from "../components/layout"; and I've confirmed that that is the correct path for the Layout component.
are you sure the file name is layout.tsx not Layout.tsx :-)
I went through the same thing.
Fix layout.tsx to Layout.tsx
The file name and component name must be the same.

I'm building a UI component library using React 18 and exporting a Button.tsx component in it.
Then, to test that I can use that Button component, i'm importing it into a different component, Test.tsx, within that same UI component library code package (using npm link) and creating a story for that component.
So Test.tsx looks like this:
import Button from 'my-component-library'
const Test = (): JSX.Element => {
return (
<>
<Button title='test' body='test' />
</>
)
}
export default Test
And this is the Story for Test.tsx:
import { Meta, Story } from '#storybook/react'
import React from 'react'
import Test from './Test'
export default {
title: 'Test',
component: Test,
} as Meta
export const Default: Story<any> = () => <Test />
But if I want to view this story, I'm getting the following error in the Storybook UI:
Couldn't find story matching 'test--default'.
- Are you sure a story with that id exists?
- Please check your stories field of your main.js config.
- Also check the browser console and terminal for error messages.
And the following error in the browser console:
Unexpected error while loading ./components/Test/Test.stories.tsx: react is not defined
ReferenceError: react is not defined
How can I fix this?
I use CSS modules in my React app. Today I was trying to code and had to upgrade some dependencies - react from 17.0.1 to 17.0.2, react-scripts from 4.0.3 to ^5.0.0, eslint from ^7.32.0 to 8.0.0 - and I had a bunch of errors. I managed to fix a lot of them, but I'm getting a lot of errors like this one:
export 'headerImageWrapper' (imported as 'headerImageWrapper') was not found in './Header.module.css' (possible exports: default)
I've been importing destructured classes from CSS modules - and it was working until today.
import React from 'react';
import logo from '../../assets/logo.png';
import {
headerWrapper,
headerImageWrapper,
headerLogo,
headerTitleWrapper,
} from './Header.module.css';
export default function Header() {
return (
<div className={headerWrapper}>
<div className={headerImageWrapper}>
<img className={headerLogo} src={logo} alt="Logo" />
</div>
<div className={headerTitleWrapper}>
<p>Biblioteca</p>
<p>Colégio</p>
</div>
</div>
);
}
It does work when I import it as "styles", but I wanted to keep it destructured so I didn't have to use "styles.headerWrapper"
I am getting this same error and don't want to revert to styles.myStyle. So right now I am still importing the entire styles object, import styles from "./blah.module.css", but then I deconstruct the variables after const {styleOne, styleTwo} = styles;. This allows you to keep everything else the same, but still kinda annoying.
I use the react-tooltip library in my Next.js app.
I noticed that every time I refresh a website while visiting a page that uses the tooltip I get an error:
react-dom.development.js:88 Warning: Prop `dangerouslySetInnerHTML` did not match.
CSS classes are different on the client and on the server
The weird part is I do not get that error while navigating from a random page to a page that uses the react-tooltip.
The tooltip related code:
<StyledPopularityTooltipIcon src="/icons/tooltip.svg" alt="question mark" data-tip="hello world" />
<ReactTooltip
effect="solid"
className="tooltip"
backgroundColor="#F0F0F0"
arrowColor="#F0F0F0"
clickable={true}
/>
I had the same issue, I had to use state to detect when component has been mounted, and show the tooltip only after that.
P.S. You don't see the error when navigating, because the page is not rendered on server when you navigate, it's all front-end :)
In case you are using any server-side rendering (like Next.js) - you will need to make sure your component is mounted first before showing the react-tooltip.
I fixed this by using the following:
import React, { useEffect, useState } from 'react';
const [isMounted,setIsMounted] = useState(false); // Need this for the react-tooltip
useEffect(() => {
setIsMounted(true);
},[]);
return (<div>
{isMounted && <ReactTooltip id={"mytip"} effect={"solid"} />}
<span data-tip={"Tip Here"} data-for={"mytip"}>Hover me</span>
</div>)
You should wrap your JSX in the following component:
import React, { useEffect, useState } from 'react';
const NoSsr = ({ children }): JSX.Element => {
const [isMounted, setMount] = useState(false);
useEffect(() => {
setMount(true);
}, []);
return <>{isMounted ? children : null}</>;
};
export default NoSsr;
Like this:
<NoSsr>
<YourJSX />
</NoSsr>
If you are working with NEXTJS this might be a good approach, you can check the documentation here as well, also if you are working with data-event, globalEventOff or any other prop and is not hiding or not working in your localhost, this only occurs in Development Strict Mode. ReactTooltip works fine in Production code with React 18. So you can set reactStrictMode : false, in your next.config.js to test it locally and then set it back to true, hope this helps :) info reference here
import dynamic from 'next/dynamic'
const ReactTooltip = dynamic(() => import('react-tooltip'), { ssr : false });
function Home() {
return (
<div>
<Button
data-tip
data-event="click focus"
data-for="toolTip"
onClick={():void => ()}
/>
<ReactTooltip id="toolTip" globalEventOff="click"/>
</div>
)
}
export default Home
I'm running into a weird problem. I'm using NextJS for its server-side rendering capabilities and I am using ReactQuill as my rich-text editor. To get around ReactQuill's tie to the DOM, I'm dynamically importing it. However, that presents another problem which is that when I try to access the component where I'm importing ReactQuill via a anchor link is not working but I can access it via manually hit the route. Here is my directories overview,
components/
crud/
BlogCreate.js
pages/
admin/
crud/
blog.js
index.js
blogs/
index.js
In my pages/admin/index.js
...
<li className="list-group-item">
<Link href="/admin/crud/blog">
<a>Create Blog</a>
</Link>
</li>
...
In my pages/admin/crud/blog.js
import BlogCreate from "../../../components/crud/BlogCreate";
...
<div className="col-md-12">
<BlogCreate />
</div>
In my components/crud/BlogCreate.js
import dynamic from "next/dynamic";
const ReactQuill = dynamic(() => import("react-quill"), { ssr: false });
import "../../node_modules/react-quill/dist/quill.snow.css";
...
<div className="form-group">
<ReactQuill
value={body}
placeholder="Write something amazing..."
onChange={handleBody}
/>
</div>
in order to use import "../../node_modules/react-quill/dist/quill.snow.css" in components/crud/BlogCreate.js I use #zeit/next-css and here is my next.config.js
const withCSS = require("#zeit/next-css");
module.exports = withCSS({
publicRuntimeConfig: {
...
}
});
Problem
when I click the Create Blog it should be redirect me http://localhost:3000/admin/crud/blog but it just freeze.
But if I manually hit http://localhost:3000/admin/crud/blog then it go to the desire page and work perfect.
And as soon as I manually load that page then Create Blog works. Now I really don't understand where is the problem? Because it show no error that's why I haven't no term to describe my problem that's why I give all the nasty code and directories which I suspect the reason of this error.
It's hard to give you any solution without seeing the entire project(As you mentioned that it shows no error).
You may remove the #zeit/next-css plugin because Next.js 9.3 is Built-in Sass Support for Global Stylesheets. You can use it for css also.
Create a pages/_app.js file if not already present. Then, import the quill.snow.css file:
import "../../node_modules/react-quill/dist/quill.snow.css";
// This default export is required in a new `pages/_app.js` file.
export default function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
If it gives any error then you can create a directory/file to copy-paste the quill.snow.css code in that file.
pages/
_app.js
styles/
quill_style.css
Then import the file in _app.js like,
import "../styles/styles_quill.css";
// This default export is required in a new `pages/_app.js` file.
export default function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
Eventually you can import your custom gobal css here also.
If although the problem remains then provide your git repository. happy coding ✌️
First: remove your #zeit/next-css setup not needed anymore since next.js version 10.
Second: update nex.js to version 10 you could then use regular import on your modules.
import "../../node_modules/react-quill/dist/quill.snow.css";
By the way, I had the same issue with your Nextjs course. ;)
I've built a fairly simple React app based on create-react-app which uses the Material-UI for its interface components. It also depends on one of my own packages which also uses Material-UI (same version) for a couple of shared components.
Things were looking good locally until I ran a production build and deployed it. Some of the styles were behaving oddly, for example the Material-UI grid was much narrower than when running locally.
I did some reading and found a few instances of people discussing colliding class names under my scenario. This took me to some official Material-UI documentation which provides the following example code to use a custom class name prefix:
import JssProvider from 'react-jss/lib/JssProvider';
import { createGenerateClassName } from '#material-ui/core/styles';
const generateClassName = createGenerateClassName({
dangerouslyUseGlobalCSS: true,
productionPrefix: 'c',
});
function App() {
return (
<JssProvider generateClassName={generateClassName}>
...
</JssProvider>
);
}
export default App;
Before applying this fix when inspecting my production app's source code I could see the outermost DIV using the CSS class jss2 jss24.
After applying this fix my production app actually visually renders the same layout as my development version and so would appear to be fixed. However, examining the source shows the outermost DIV to have the class MuiGrid-container-2 MuiGrid-spacing-xs-8-24 which suggests to me something isn't right. I could leave it like this but it does mean I'm running with unoptimised code.
Am I doing something wrong here? Or is there an alternative resolution? I'm using current latest version of #material-ui/core (3.3.2) and the full contents of my App.js are:
import React, { Component } from 'react';
import { Provider } from "react-redux";
import { OidcProvider } from 'redux-oidc';
import JssProvider from 'react-jss/lib/JssProvider';
import Routes from './routes';
import store from './store';
import userManager from './utils/userManager';
import {
CustomUiTheme as Theme,
CustomUiLayout as Layout,
CustomUiSnackbar as Snackbar,
CustomUiModalAlert as Alert
} from 'custom-ui';
import Loading from './components/loading';
import { createGenerateClassName } from '#material-ui/core/styles';
const generateClassName = createGenerateClassName({
dangerouslyUseGlobalCSS: true,
productionPrefix: 'tw',
});
class App extends Component {
render() {
return (
<JssProvider generateClassName={generateClassName}>
<Provider store={store}>
<OidcProvider store={store} userManager={userManager}>
<Theme>
<Loading />
<Layout variant="xmas">
<Alert />
<Routes />
<Snackbar />
</Layout>
</Theme>
</OidcProvider>
</Provider>
</JssProvider>
);
}
}
export default App;
