Plugins

How to use

Darkmode.extend([pluginA, pluginB, pluginC]);

Note: Darkmode.extend() must be executed before Darkmode.run(), otherwise the plugin will not work.

Make your plugin

Overview

Darkmode will provide the plugin base class Plugin parameter through the extend method. When you write your own plugins, you need to inherit the plugin base class. You can use some built-in properties and methods by the plugin base class, and you can use plugin hooks to write your own logic.

export default function (Plugin) {
  return class extends Plugin {
    constructor() {
      super(); // The plugin base class contains some built-in properties and methods

      ... // Plugin properties can be customized here
    }

    // BEGIN: Plugin Hook
    beforeConvertNode(el) {}

    afterConvertNode(el) {}

    afterConvertTextColor(el, opt) {}
    // END: Plugin Hook

    ... // Plugin methods can be customized here
  }
};

Built-in properties and methods

All built-in properties and methods can be accessed in plugins via this.

Built-in properties

• loopTimes <number> The number of times it has been traversed (one time when all nodes are traversed).
• isDarkmode <boolean> Whether it is Dark Mode.

Built-in methods

addCss(className, kvList, needMediaQuery)

• className <string> DOM class name.
• kvList <Array> List of css key-value pairs.
  • kvList[0].key <string> CSS property.
  • kvList[0].value <string> CSS value.
• needMediaQuery <boolean> Whether the Dark Mode media query needs to be added.

Add styles.

this.addCss('test_class1', [{
  key: 'color',
  value: '#DDD'
}, {
  key: 'text-align',
  value: 'center'
}], true);

this.addCss('test_class2', [{
  key: 'cursor',
  value: 'pointer'
}], true);

// Result
// @media (prefers-color-scheme: dark) {.test_class1{color: #DDD !important;text-align: center !important;}.test_class2{cursor: pointer !important;}}

Hooks

beforeConvertNode(el)

• el <DOM Object> The currently transformed node.

Hook before the node starts transforming.

Note: If you operate on the node in this hook (such as modifying the inline style), it will affect the subsequent conversion results. If you don't want to affect the conversion result, it is recommended to use the afterConvertNode() hook.

afterConvertTextColor(el, opt)

• el <DOM Object> The currently transformed node.
• opt <Object> Text color object.
  • opt.fontColor <Color Object> The text foreground color Color object.
  • opt.bgColor <Color Object> Text background color Color object.

Hook after the text style conversion.

Note: The Color object is based on color. Please keep the same version when using it(refer to package.json for the version).

afterConvertNode(el)

• el <DOM Object> The currently transformed node.

Hook after the node conversion.
