 */
function toLine(name) {
  return name.replace(/\B([A-Z])/g, '-$1').toLowerCase()

`transform: string | function(importName: string): string`

The library name to use instead of the one specified in the import statement. ${member} will be replaced with the import name, aka Grid/Row/Col/etc., and ${1-n} will be replaced by any matched regular expression groups. If using a JS Babel config file, a function may be passed directly. (see Programmatic Usage)

`preventFullImport: boolean`

default false

Whether or not to throw when an import is encountered which would cause the entire module to be imported.

`skipDefaultConversion: boolean`

default false

When set to true, will preserve import { X } syntax instead of converting to import X.

// Input Code
import { Grid as gird } from 'uiw';
// Output   ↓ ↓ ↓ ↓ ↓ ↓  ====> skipDefaultConversion: true
import { Grid as gird } from 'uiw/lib/Grid';

- import { Grid as gird } from 'uiw';
+ import { Grid as gird } from 'uiw/lib/Grid';

Programmatic Usage

import plugin from 'babel-plugin-transform-uiw-import'
import { transform } from 'babel-core'

// `CopyToClipboard` => `copy-to-clipboard`
function toLine(name) {
  return name.replace(/\B([A-Z])/g, '-$1').toLowerCase();
}
 
function replace (code) {
  return transform(code, {
    babelrc: false,
    plugins: [
      [plugin, {
        'date-fns': {
          transform: importName => `date-fns/${toLine(importName)}`,
          preventFullImport: true,
        },
      }]
    ],
  }).code;
}
 
replace("import { CopyToClipboard } from 'date-fns';")
//=> "import CopyToClipboard from "date-fns/copy-to-clipboard";"
