Uppy is a sleek, modular JavaScript file uploader that integrates seamlessly
with any application. It’s fast, provides a comprehensible API and lets you
worry about more important problems than building a file uploader.

- **Fetch** files from local disk, remote urls, Google Drive, Dropbox, or snap
  and record selfies with a camera;
- **Preview** and edit metadata with a nice interface;
- **Upload** to the final destination, optionally process/encode

**[Read the docs](https://uppy.io/docs)** |
**[Try Uppy](https://uppy.io/examples/dashboard/)**

Uppy is being developed by the folks at [Transloadit](https://transloadit.com),
a versatile file encoding service.

## Example

```js
import Uppy from '@uppy/core'

const uppy = new Uppy()
uppy.use(SomePlugin)
```

## Installation

```bash
$ npm install @uppy/core
```

Alternatively, you can also use this plugin in a pre-built bundle from
Transloadit’s CDN: Smart CDN. In that case `Uppy` will attach itself to the
global `window.Uppy` object. See the
[main Uppy documentation](https://uppy.io/docs/#Installation) for instructions.

## Documentation

Documentation for this plugin can be found on the
[Uppy website](https://uppy.io/docs/uppy).
