theme-color-switch
This a script to switch color specific styles less file and which you can use to change theme dynamically in browser.
Also you can use these less syntax functions for color conversion.

$ npm install theme-color-switch
Demo
Try out the demo
Example:
const less = require('theme-color-switch');
const colorSource = require('!raw-loader!./public/color.less'); // theme file content which generate by theme-color-generator
less.render(
colorSource,
{
modifyVars: {
'@theme-color': '#0035ff' // the variables in theme file which you want to change
},
},
function(e, output) {
if (e) {
console.error(`Failed to update theme`);
}
if (output && output.css) {
addCSS(output.css);
}
}
);
Note: You need to generate color.less
file with theme-color-generator ( as color.js
in example ) first, then toggle color with this package as Theme.js
in example
Now you can change colors by modify less avriables as the example
如只想使用主题切换的,上面的内容就已完成。
