Detect dark mode using JavaScript

问题

Windows and macOS now have dark mode.

For CSS I can use:

@media (prefers-dark-interface) { 
  color: white; background: black 
}

But I am using the Stripe ELements API, which puts colors in JavaScript

For example:

  const stripeElementStyles = {
    base: {
      color: COLORS.darkGrey,
      fontFamily: `-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"`,
      fontSize: '18px',
      fontSmoothing: 'antialiased',
      '::placeholder': {
        color: COLORS.midgrey
      },
      ':-webkit-autofill': {
        color: COLORS.icyWhite
      }
    }
  }

How can I detect the OS's preferred color scheme in JavaScript?

回答1:

if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
    // dark mode
}
