next js styled components classname did not match
To resolve the issue of mismatched class names when using styled-components with Next.js, you can follow the steps below:
- Install the necessary packages: Install both
styled-components
andbabel-plugin-styled-components
packages in your Next.js project. You can use the following command to install them:
npm install styled-components babel-plugin-styled-components
- Create a
.babelrc
file: In the root directory of your Next.js project, create a file named.babelrc
if it doesn't already exist. This file is used to configure Babel, the JavaScript compiler used by Next.js. Open the.babelrc
file and add the following configuration:
json
{
"presets": ["next/babel"],
"plugins": [["styled-components", { "ssr": true }]]
}
This configuration sets up the styled-components
plugin to work with server-side rendering (SSR) in Next.js.
- Create a custom
_app.js
file: In thepages
directory of your Next.js project, create a file named_app.js
(if it doesn't already exist). This file is used to customize the Next.js app component. Open the_app.js
file and add the following code:
```jsx import { createGlobalStyle, ThemeProvider } from 'styled-components';
const GlobalStyle = createGlobalStyle/ Add your global styles here /
;
function MyApp({ Component, pageProps }) {
return (
export default MyApp; ```
Here, you can define any global styles using the createGlobalStyle
function from styled-components
. Replace the empty object {}
in the ThemeProvider
component with your desired theme.
- Import and use styled-components: In your React components, import
styled
fromstyled-components
and use it to create styled components. You can define styles using tagged template literals. For example:
```jsx import styled from 'styled-components';
const Button = styled.button/ Add your styles here /
;
function MyComponent() { return ; } ```
You can now use the Button
component in your application, and Next.js will handle the class names correctly.
By following these steps, you should be able to resolve the issue of mismatched class names when using styled-components with Next.js.
