ts-import-plugin

Modular import plugin for TypeScript, compatible with antd, antd-mobile and so on.

webpack template ./webpack.config.js, run: npm start to see the bundle analyzer.

This plugin is not work if your are using import * as _ from 'lodash' or import _ from 'lodash'

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

// 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

Due to https://github.com/s-panferov/awesome-typescript-loader/issues/447, awesome-typescript-loader is not working with any TypeScript plugin, include this one.

Options

options can be an object:

• libraryName string

  default 'antd'

• style boolean | 'css'

  default false

• libraryDirectory string

  default 'lib'

• camel2DashComponentName boolean

  default true

• camel2UnderlineComponentName boolean

  default false

example:

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

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

options can be an array:

example:

[
  {
    libraryName: 'antd',
    libraryDirectory: 'lib',
    style: true
  }, {
    libraryName: 'material-ui',
    libraryDirectory: 'components',
    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' })

material-ui

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

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

RxJS

only compatible for 5.5+

transformerFactory({
  libraryDirectory: '../_esm2015/operators',
  libraryName: 'rxjs/operators',
  style: false,
