# Uppy

Hi, thanks for trying out the bundled version of the Uppy File Uploader. You can
use this from a CDN
(`<script src="https://releases.transloadit.com/uppy/v5.2.1/uppy.min.js"></script>`)
or bundle it with your webapp.

Note that the recommended way to use Uppy is to install it with yarn/npm and use
a bundler like Webpack so that you can create a smaller custom build with only
the things that you need. More info on
<https://uppy.io/docs/#With-a-module-bundler>.

## How to use this bundle

You can extract the contents of this zip to a directory, such as `./js/uppy`.

Now you can create an HTML file, for example `./upload.html`, with the following
contents:

```html
<html>
  <head>
    <link rel="stylesheet" href="./js/uppy/uppy.min.css" />
  </head>

  <body>
    <div class="DashboardContainer"></div>
    <button class="UppyModalOpenerBtn">Upload</button>
    <div class="uploaded-files">
      <h5>Uploaded files:</h5>
      <ol></ol>
    </div>
  </body>

  <script type="module">
    import { Uppy, Dashboard, Tus } from './js/uppy/uppy.min.mjs'
    var uppy = new Uppy({
      debug: true,
      autoProceed: false,
    })
      .use(Dashboard, {
        browserBackButtonClose: false,
        height: 470,
        inline: false,
        replaceTargetContent: true,
        showProgressDetails: true,
        target: '.DashboardContainer',
        trigger: '.UppyModalOpenerBtn',
        metaFields: [
          { id: 'name', name: 'Name', placeholder: 'file name' },
          {
            id: 'caption',
            name: 'Caption',
            placeholder: 'describe what the image is about',
          },
        ],
      })
      .use(Tus, { endpoint: 'https://tusd.tusdemo.net/files/' })
      .on('upload-success', function (file, response) {
        var url = response.uploadURL
        var fileName = file.name

        document.querySelector('.uploaded-files ol').innerHTML +=
          '<li><a href="' + url + '" target="_blank">' + fileName + '</a></li>'
      })
  </script>
</html>
```

Now open `upload.html` in your browser, and the Uppy Dashboard will appear.

## Next steps

In the example you built, Uppy uploads to a demo server where files will be
deleted shortly after uploading. You’ll want to target your own tusd server, S3
bucket, or Nginx/Apache server. For the latter, use the Xhr plugin:
<https://uppy.io/docs/xhr-upload/> which uploads using regular multipart form
posts, that you’ll existing Ruby or PHP backend will be able to make sense of,
as if a `<input type="file">` had been used.

The Dashboard now opens when clicking the button, but you can also draw it
inline into the page. This, and many more configuration options can be found
here: <https://uppy.io/docs/dashboard/>.

Uppy has many more Plugins besides Xhr and the Dashboard. For example, you can
enable Webcam, Instagram, or video encoding support. Note that for some Plugins,
you will need to run a server side component called: Companion. Those plugins
are marked with a (c) symbol. Alternatively, you can sign up for a free
Transloadit account. Transloadit runs Companion for you, tusd servers to handle
resumable file uploads, and can post-process files to scan for viruses,
recognize faces, etc. Check: <https://transloadit.com>.
