shupload

shupload is free software that provides quick image hosting and sharing through a self-run HTTP service written in Go.

Features

• Free software!
• URL shortening such as website.net/Xo3lgeZ9
  • Customizable to be any array of characters or strings!
• Mobile support
• Image uploading via:
  • File open dialog
  • Drag'n'drop
  • Clipboard pasting
  • Camera capturing
  • Display/Window capturing for browsers implementing MediaDevices.getDisplayMedia()
• Customizable via HTML templates and CSS.
• Works without JavaScript, albeit with a degraded experience and no features beyond standard input-based file upload.
• Metadata such as the filename, upload date, and mimetype are stored in an adjacent JSON metadata file, meaning the original file's name is preserved for downloading.
• Zooming with pixel-perfect upscaling for modern browsers.

Installation

To install you must have at least have Go 1.11. In the future binaries may be provided but until then you can simply issue the following:

~> git clone https://github.com/kettek/shupload
~> cd shupload/src && go build -o ../shupload
~> cd .. && ./shupload

Running

Running is simply a matter of running shupload in a directory relative to the static and templates directories. Doing so will start an HTTP service running at 127.0.0.1:8088/. Additional configuration can be provided as per the following section.

Configuration

shupload configuration can be done through a JSON file named config.json relative to the running directory of the program.

The possible options are:

Key	Type	Default	Description
Address	string	":8088"	The address and port for HTTP listening.
DatabaseLocation	string	"db"	The directory name/location of the database storage.
EntryKeyRunes	[]string	["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"]	The runes from which to randomly generate an entry's key.
EntryKeyLength	int	8	How many runes an entry should consist of.
MaxFilenameLength	int	100	The maximum runes allowed for uploaded file names.
MaxFileSize	int	20000	The maximum file size allowed in kilobytes.

Storage format

shupload uses a simple file-based storage provided by DataBase_filestore.go. It writes uploaded image data under the db directory and the accompanying metadata (upload time, filename, mimetype) entries in the db.json file.

Alternative database solutions could be created by replicating the base API of the filestore implementation.

nginx Reverse Proxy

Running shupload behind an nginx proxy is a fairly easy matter. Depending on your server(s') setup, a location entry such as the one below will allow shupload to work without error:

location /upload/ {
	proxy_pass http://127.0.0.1:8088/;
	proxy_redirect ~^/(.*) https://<mydomain>/upload/$1;
}

Additionally, nginx limits file uploads to 1M so you may wish to place the following line in either the location, server, or global sections:

	client_max_body_size 100M;
