Prefers color scheme is a package that tells you a user's preferred color scheme. It's based on the CSS @media (prefers-color-scheme). It's around 700 bytes minified, 300 bytes gzipped.

Add the dependency from NPM:

npm install prefers-color-scheme

Import the package:

import prefersColorScheme from "prefers-color-scheme";

Then call the function:

const colorScheme = prefersColorScheme();
// Returns "light" or "dark"

This package only works in browsers that natively support @media (prefers-color-scheme), so it just returns "light" in unsupported browsers. Current browser support

By passing false as the argument, you can get "unsupported" as the value for unsupported browsers:

const colorScheme = prefersColorScheme(false);
// Returns "light", "dark", or "unsupported"

Install dependencies:

yarn

Compile Typescript to ES6 before publishing to NPM:
