Package Exports

ts-import-plugin

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ts-import-plugin) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Why use this

transform such code:

import { Alert, Card as C } from 'antd'

into:

import Alert from 'antd/lib/alert'
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/
      }
    ]
  },
  // ...
}

Options

options can be an object:

libraryName string

default 'antd'
style boolean | string | ((path: string) => string)

default false
libraryDirectory string | ((name: string) => string)

default 'lib'
camel2DashComponentName boolean

default true
camel2UnderlineComponentName boolean

default false

example:

tsImportPluginFactory({
  libraryName: 'antd',
  libraryDirectory: 'lib',
  style: true
})

{
  libraryName: 'material-ui',
  libraryDirectory: '',
  camel2DashComponentName: false
}

options can be an array:

example:

[
  {
    libraryName: 'antd',
    libraryDirectory: 'lib',
    style: true
  }, {
    libraryName: 'material-ui',
    libraryDirectory: '',
    camel2DashComponentName: false
  }
]

Compatible libs:

ant-design

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' })

material-ui

import { FloatingActionButton } from 'material-ui'
import { ContentRemove, NavigationRefresh, ContentAdd } from 'material-ui/svg-icons'

transformerFactory({
  libraryName: 'material-ui',
  libraryDirectory: '',
  camel2DashComponentName: false
})

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

    return stringVec
      .reduce((acc, cur, index) => {
        if (index > 1) {
          return acc + '-' + cur
        } else if (index === 1) {
          return acc + '/' + cur
        }
        return acc + cur
      }, '')
  },
  libraryName: 'material-ui/svg-icons',
  style: false,
  camel2DashComponentName: false
})
