import 'antd/lib/alert/style/index.less'
import { default as C } from 'antd/lib/card'
import 'antd/lib/card/style/index.less'

Usage

With ts-loader

//tsconfig.json
{
  ...
  "module": "ESNext",
  ...
}

// webpack.config.js
const tsImportPluginFactory = require('ts-import-plugin')

module.exports = {
  // ...
  module: {
    rules: [
      {
        test: /.(jsx|tsx|js|ts)$/,
        loader: 'ts-loader',
        options: {
          transpileOnly: true,
          getCustomTransformers: () => ({
            before: [ tsImportPluginFactory( /** options */) ]
          }),
          compilerOptions: {
            module: 'es2015'
          }
        },
        exclude: /node_modules/
      }
    ]
  },
  // ...
}

With awesome-typescript-loader ( >= 3.5.0 )

//tsconfig.json
{
  ...
  "module": "ESNext",
  ...
}

// webpack.config.js
const tsImportPluginFactory = require('ts-import-plugin')

module.exports = {
  // ...
  module: {
    rules: [
      {
        test: /.tsx?$/,
        loader: 'awesome-typescript-loader',
        options: {
          getCustomTransformers: () => ({
            before: [ tsImportPluginFactory( /** options */) ]
          }),
        },
        exclude: /node_modules/
      }
    ]
  },
  // ...
}

With rollup

import typescript from 'rollup-plugin-typescript2'
import createTransformer from 'ts-import-plugin'

const transformer = createTransformer({
  libraryDirectory: 'es',
  libraryName: 'antd',
  style: true
})
export default {
  input: ./test/fixtures/index.tsx,
  plugins: [typescript({
    clean: true,
    transformers: [() => ({
      before: transformer,
    })]
  })],
  output: [
    {
      file: ./dist/rollup.dist.js,
      format: 'esm',
    },
  ],
}

const transformerFactory = require('ts-import-plugin')
// with less
transformerFactory({ style: true })
// with css
transformerFactory({ style: 'css' })
// without style
transformerFactory()

lodash

notice you should manual

import 'lodash/core'

in your project if your are using

import { chain } from 'lodash'

.

transformerFactory({
  style: false,
  libraryName: 'lodash',
  libraryDirectory: null,
  camel2DashComponentName: false
})

antd-mobile

// with css.web
transformerFactory({ libraryName: 'antd-mobile', style: 'css', styleExt: 'css.web' })

// antd-mobile recently changed styleExt. If error occurs with prev, try next.
transformerFactory({ libraryName: 'antd-mobile', style: 'css' })

})

// svg-icons
transformerFactory({
  libraryDirectory: importName => {
    const stringVec = importName.split(/([A-Z][a-z]+|[0-9]*)/)
