Semi Design uses the Scss variables to extract thousands of Design Tokens. You can replace Token through this plugin to achieve theme customization. More info
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 {SemiRspackPlugin} = require('@douyinfe/semi-rspack-plugin');
module.exports = {
// ...
plugins: [
new SemiRspackPlugin({
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
$font-size-small: 16px;
- step2: config rspack
// rspack.config.js
const path = require('path');
const {SemiRspackPlugin} = require('@douyinfe/semi-rspack-plugin');
module.exports = {
// ...
plugins: [
new SemiRspackPlugin({
include: path.join(__dirname, 'local.scss')
})
]
};
Through parameters
// rspack.config.js
const {SemiRspackPlugin} = require('@douyinfe/semi-rspack-plugin');
module.exports = {
// ...
plugins: [
new SemiRspackPlugin({
variables: {
"$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 {SemiRspackPlugin} = require('@douyinfe/semi-rspack-plugin');
module.exports = {
// ...
plugins: [
new SemiRspackPlugin({
prefixCls: 'custom'
})
]
// ...
};
Then you get the replaced CSS selectors(e.g, .custom-button
).

Type: Object
The key-value pair of Scss token.
options.omitCss

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.
In webpack@5, some hooks need to be obtained through api NormalModule.getCompilationHooks
. But in some scenarios, webpack will not be installed, such as Next.js. Therefore, the user is required to pass in NormalModule as a parameter.
