What is the best way to transmit the "theme" property to "Components" within a next.js application?

I'm currently working on a next.js app and dealing with the _app.tsx file:

import '../styles/globals.css'
import type { AppProps } from 'next/app'
import { createTheme } from '@arwes/design'
import { ThemeProvider, Global, css } from '@emotion/react'
import { globalStyles, blueOnBlack } from '../shared/styles.js'

function MyApp({ Component, pageProps }: AppProps) {
  const theme = createTheme();
  return (
    <ThemeProvider theme={theme}>
      {globalStyles}
      <div style={blueOnBlack(theme)}>
        Futuristic Sci-Fi UI Web Framework
      </div>

      <Component {...pageProps} />
    </ThemeProvider>
  )
}

export default MyApp

An issue I'm facing is needing to access the theme in index.tsx. How can I effectively pass this information into Component?

Answer №1

When working with child components, remember to include:

const style =  useContext(StyleProvider)

Answer №2

By utilizing emotion's useTheme(), I successfully accessed the parent's theme. It was necessary to construct the component outside of the render section within the page's exported function, as illustrated in the index.tsx file:

function CustomText(props: any) {
  const theme = useTheme()
  return <div style={{ color: theme.palette.primary.dark3 }} {...props} />
}


// The defined "CustomText" function can now be utilized as a component in the "Home" component


const Home: NextPage = () => {
    return (
   ...
    <CustomText className={styles.description}>
      Get started by editing{' '}
      <code className={styles.code}>pages/index.tsx</code>
    </CustomText>
   ...
  )  
}

export default Home

This setup functions effectively due to the color being specified as "dark3" in the text above.
