color-scheme-fallback v0.8.2

color-scheme-fallback

color-scheme-change with legacy fallback way (using hash parameter)

How we can turn on/off dark mode on some legacy device environments?
As an alternative way, it checks hash value, (e.g. '#?drkmd=y'), updates the color scheme, and stores the value for later visit.
Programmatically, you will be able to force-change media query accordingly.

install

$ npm i --save color-scheme-fallback

API

new ColorSchemeFallback({
 onChange: (scheme) => {}, // callback function when color scheme has changed
 storeScheme: true         // true/false
 hashFlag: 'darkmode',     // which name to watch for color scheme (default: drkmd)
 nativeFirst: true         // false, if you want to set only by manually using hashFlag
})
