You can custom theme through three ways:

  • npm package for custom theme
  • Local Scss file in your project
  • Pass key-value pair parameters to plugin Priority from low to high.

Through npm package

In order to use the npm package, you need to customize the theme through Semi Design System.After finishing the customization, Semi DSM will generate a npm package for you, and then you can use it like this.

// rspack.config.js
const SemiPlugin = require('@douyinfe/semi-rspack-plugin').default;

module.exports = {
    // ...
    plugins: [
        new SemiPlugin({
            theme: '@douyinfe/semi-theme-default'
        })
    ]
    // ...
};

Through local Scss file

You can check which tokens can be customized on the Semi WebSite.

  • step1: add a local file
// local.scss
$font-size-small: 16px;
  • step2: config rspack
// rspack.config.js
const path = require('path');
const SemiPlugin = require('@douyinfe/semi-rspack-plugin').default;

module.exports = {
    // ...
    plugins: [
        new SemiPlugin({
            include: path.join(__dirname, 'local.scss')
        })
    ]
};

Through parameters

// rspack.config.js
const SemiPlugin = require('@douyinfe/semi-rspack-plugin').default;

module.exports = {
    // ...
    plugins: [
        new SemiPlugin({
            variables: {
                "$font-size-small": '16px'
            }
        })
    ]
};

Replace prefix of CSS selector

The CSS selectors used by Semi Design is prefixed with semi by default(e.g, .semi-button).You can replace the prefix through this plugin.

// rspack.config.js
const SemiPlugin = require('@douyinfe/semi-rspack-plugin').default;

module.exports = {
    // ...
    plugins: [
        new SemiPlugin({
            prefixCls: 'custom'
        })
    ]
    // ...
};

Then you get the replaced CSS selectors(e.g, .custom-button).

options.overrideStylesheetLoaders

Type: (loaderList:any[])=>any[]

You can customize how webpack process semi related styles by override the loader with this option. The function will receive the loader list of default loaders(include options.extractCssOptions) and you should return your new loader list. The best practice is just only add your loader to the list rather than delete or change the default loaders since some core logic is in there.
