antd-theme-generator

This script generates color specific styles/less file which you can use to change theme dynamically in browser

Example:

const { generateTheme } = require('antd-theme-generator');

const options = {
  antDir: path.join(__dirname, './node_modules/antd'),
  stylesDir: path.join(__dirname, './src'), // all files with .less extension will be processed
  varFile: path.join(__dirname, './src/styles/variables.less'), // default path is Ant Design default.less file
  themeVariables: ['@primary-color'],
  outputFilePath: path.join(__dirname, './public/color.less') // if provided, file will be created with generated less/styles
  customColorRegexArray: [/^fade\(.*\)$/], // An array of regex codes to match your custom color variable values so that code can identify that it's a valid color. Make sure your regex does not adds false positives.
}

generateTheme(options).then(less => {
  console.log('Theme generated successfully');
})
.catch(error => {
  console.log('Error', error);
})

Property	Type	Default	Descript
antdDir	string	-	This is path to antd directory in your node_modules
stylesDir	string, [string]	-	Path/Paths to your custom styles directory containing .less files
varFile	string	-	Path to your theme related variables file
themeVariables	array	['@primary-color']	List of variables that you want to dynamically change
outputFilePath	string	-	Generated less content will be written to file path specified otherwise it will not be written. However, you can use returned output and write in any file as you want
customColorRegexArray	array	['color', 'lighten', 'darken', 'saturate', 'desaturate', 'fadein', 'fadeout', 'fade', 'spin', 'mix', 'hsv', 'tint', 'shade', 'greyscale', 'multiply', 'contrast', 'screen', 'overlay'].map(name => new RegExp(${name}\(.*\)))]	This array is to provide regex which will match your color value, most of the time you don't need this

Add following lines in your main html file

<link rel="stylesheet/less" type="text/css" href="/color.less" />
<script>
  window.less = {
    async: true,
    env: 'production'
  };
</script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js"></script>

Now you can update colors by updating less variables like this

window.less.modifyVars({
  '@primary-color': '#0035ff'
})

stylesDir can be a string or array of strings (['path1', 'path2']) if you have more than one styles directories in your project or you want to specify some sub directories e.g your component and containers directories containing styles for each component inside that directory.
