contented

A file / image / paste upload server with a focus on embedding.

You can use contented as a standalone upload server, or you can use the SDK to embed its upload widget into another website.

Features

  • Drag and drop upload
  • Multiple files upload
  • Pastebin upload
  • Custom drawing upload (via drawingboard.js)
  • Ctrl-V upload
  • SDK-oriented design for embedding, including CORS support
  • Mobile friendly HTML interface
  • Preserves uploaded filename and content-type metadata
  • Hash verification (SHA512/256)
  • Detect duplicate upload content and reuse storage
  • Options to limit the upload filesize and the upload bandwidth
  • Short URLs (using Hashids algorithm)
  • Image thumbnailing

Usage (Server)

Usage of contented:
  -data string
        Directory for stored content (default "")
  -db string
        Path for metadata database (default "contented.db")
  -diskFilesWorldReadable
        Save files as 0644 instead of 0600
  -enableHomepage
        Enable homepage (disable for embedded use only) (default true)
  -listen string
        IP/Port to bind server (default "127.0.0.1:80")
  -max int
        Maximum size of uploaded files in MiB (set zero for unlimited) (default 8)
  -speed int
        Maximum upload speed in bytes/sec (set zero for unlimited)
  -title string
        Title used in web interface (default "contented")
  -trustXForwardedFor
        Trust X-Forwarded-For reverse proxy headers
  -concurrentthumbs
        Simultaneous thumbnail generation (default 16)

If you are hosting behind a reverse proxy, remember to set its post body size parameter appropriately (e.g. client_max_body_size for nginx).

Usage (HTTP)

The server responds on the following URLs:

URL Method Description
/get/{ID} GET Download item content
/info/{ID} GET Get item content metadata (JSON)
/thumb/{Type}/{ID} GET Get item thumbnail image
/about GET Get server metadata (JSON)

Usage (Embedding for web)

Your webpage should load the SDK from the contented server, then call the contented.init function to display the upload widget over the top of an existing DOM element. Your callback will be passed an array of file IDs of any uploaded items.

<script type="text/javascript" src="SERVER_ADDR/sdk.js"></script>
contented.init("#target", function(/* String[] */ items) {});
