A CanJS Component that enables live-bound file drag-and-drop-ability to its contents.

Installation

npm install file-droplet --save

You can use any of the builds in the dist folder to meet your project needs.

Using CanJS's built-in support for StealJS, you can now import the module directly inside your templates. For example:

<can-import from="file-droplet"/>

<file-droplet>
  <h2>List of Files</h2>
  <ul>
    {{#each files}}
      <li>
        <span>{{name}}</span>
        <span>{{extension}}</span>
      </li>
    {{/each}}
  </ul>

  <h2>List of Extensions</h2>
  <ul>
    {{#each fileTypes}}
      <li>
        <!-- %key is the file extension. -->
        {{%key}}

        <ul>
          {{#each .}}
            <li>
              <span>{{name}}</span>
              <span>{{extension}}</span>
            </li>
          {{/each}}
        </ul>
      </li>
    {{/each}}
  </ul>
</file-droplet>

Usage

The file-droplet component is meant to be used as a wrapper for content in your stache templates. It will allow you to drag and drop files inside its borders and provides live-bound attributes that you can utilize to list and process files. A couple of possible use cases include a file-upload component or the file-router component. See the API, below, for the list of attributes that you can use.

It comes with a single style: file-droplet {display: inline-block;}, so it won't get in the way of your design.

API

• files: The master list of files. As you continue to drop more files, this list will grow.
• fileTypes: An object keyed by file extension. Each key will contain the list of all files with that extension. Files without an extension will be available on the other key.
• batches: Each time a file drop occurs, an array of files is created, whether it was one file or many. The batches property is an array that contains the list of each dropped batch.
• lastFileBatch: This is a virtual property that will return the last batch in the batches list.

Options:

There are currently no configurable options.
