|
| 3 | **date-fns** v2.x provides support for
|
| 4 | [ECMAScript Modules](http://www.ecma-international.org/ecma-262/6.0/#sec-modules)
|
| 5 | that enables tree-shaking for bundlers, like [rollup.js](http://rollupjs.org)
|
| 6 | and [webpack](https://webpack.js.org).
|
| 7 |
|
| 8 | If you have tree-shaking enabled in your bundler, just import functions normally:
|
| 9 |
|
| 10 | ```javascript
|
| 11 | import { format, parse } from 'date-fns'
|
| 12 | import { enUS, eo } from 'date-fns/locale'
|
| 13 | import { addDays, addHours } from 'date-fns/fp'
|
| 14 | ```
|
| 15 |
|
| 16 | In TypeScript, now you can import individual functions in more idiomatic way:
|
| 17 |
|
| 18 | ```typescript
|
| 19 | // Before
|
| 20 | import * as format from 'date-fns/format'
|
| 21 |
|
| 22 | // Now
|
| 23 | import format from 'date-fns/format'
|
| 24 | ```
