DropLink

A simple private file sharing site, similar to file hosters.

Upload a single file on an upload page (authenticate via a private URL) and get a download URL that's hard to guess. Data is stored on the filesystem.

If you want, uploaded files are cleaned up after a specified amount of time.

DropLink generates URLs like this:

https://example.com/dl/5Riewe4y/README.md

The URLs also work as short-URLs without the last filename part:

https://example.com/dl/5Riewe4y

Installation

Compilation requires Go.

go get https://frister.net/go/droplink

Running

DropLink is configurable via environment variables. When running on the public internet, you should at least specify an ADDRESS and an UPLOAD_SECRET and use a reverse proxy with TLS in front of DropLink.

Available environment variables:

• ADDRESS - Address to listen on. Default: localhost:8000
• DATA_DIR - Where to store the uploaded files. Default: ./data
• PATH_PREFIX - URL path prefix to strip before handling the request. Required when running in a subpath behind a reverse proxy. Example: /downloads, default: (empty)
• URL_PREFIX - Absolute URI that's used as prefix for generated URLs, with trailing slash (/). Example: https://example.com/downloads/, default: http://localhost:8000
• UPLOAD_SECRET - Secret required for uploading files, you'll later have to put it into the URL, so might not want to use any fancy characters. Example: 2db19923c912b3ebbc373067
  • OpenSSL can generate such a secret for you: openssl rand 12 -hex
• CLEANUP_AFTER_HOURS - Delete files after the specified number of hours. Also requires CLEANUP_EVERY_MINUTES to be set. Example: 720 for 30 days (24 * 30), default: (no deletion)
• CLEANUP_EVERY_MINUTES - Check for files to delete every X minutes. Also requires CLEANUP_AFTER_HOURS to be set.

With the environment variables set, you can run droplink:
