vite-plugin-style-import

English | 中文

A plug-in that imports component library styles on demand

Why only import styles

Because vite itself has imported the component library on demand, only the style is not on demand, so just import the style on demand.

Install (yarn or npm)

node version: >=12.0.0

vite version: >=2.0.0

yarn add vite-plugin-style-import -D

or

npm i vite-plugin-style-import -D

  VantResolve,
  ElementPlusResolve,
  NutuiResolve,
  AntdResolve,
} from 'vite-plugin-style-import'

export default (): UserConfigExport => {
  return {
    // 1. If you are using the ant-design series, you need to configure this
    // 2. Make sure less is installed in the dependency `yarn add less -D`
    css: {
      preprocessorOptions: {
        less: {

          NutuiResolve(),
          AntdResolve(),
        ],
        libs: [
          // If you don’t have the resolve you need, you can write it directly in the lib, or you can provide us with PR
          {
            libraryName: 'ant-design-vue',
            esModule: true,
            resolveStyle: (name) => {

  // default: false
  esModule?: boolean;

  /**
   * There may be some component libraries that are not very standardized.

   * default: false
