ass

ass is a self-hosted ShareX upload server written in Node.js. I initially started this project purely out of spite.

Access types

Type	What is it?
ZWS (Zero-width spaces)	The "fancy" mode. When pasted elsewhere, the URL appears to be just your domain name.
Mixed-case alphanumeric	The "safe" mode. URL's are browser safe as the character set is just letters & numbers.
Original	The "basic" mode. URL matches the same filename as when the file was uploaded. This may be prone to conflicts with files of the same name.

Installation

The installation may look daunting but it's really pretty straightforward. Just follow it word-for-word & you'll be fine. If you are not fine, then by all means open an Issue & I'll try my best to help.

1. First of all you must have Node.js 14 or later installed. It might work with Node.js 12 but just use 14.
2. Clone this repo using git clone https://github.com/tycrek/ass.git && cd ass/
3. Run npm i to install the required dependencies
4. Run npm run setup to start the easy configuration
5. Run npm start to start the server. The first time you run it you will be shown your first authorization token; save this as you will need it to configure ShareX.
6. (Optional) You must also configure an SSL-enabled reverse proxy (only if you want to use HTTPS):
   • I personally use Caddy, see my tutorial on setting that up
   • You may also use Apache or Nginx as reverse proxies

Generating new tokens

If you need to generate a new token at any time, run npm run new-token. This will automatically load the new token so there is no need to restart ass.

Cloudflare users

In your Cloudflare DNS dashboard, make sure your domain/subdomain is set to DNS Only.

Configure ShareX

1. Add a new Custom Uploader in ShareX by going to Destinations > Custom uploader settings...
2. Under Uploaders, click New & name it whatever you like.
3. Set Destination type to Image, Text, & File
4. Request tab:
   • Method: POST
   • URL: https://your.domain.name.here/
   • Body: Form data (multipart/form-data)
   • File from name: file (literally put "file" in the field)
   • Headers:
     • Name: Authorization
     • Value: (the value provided by npm start on first run)
5. Response tab:
   • URL: $json:.resource$
   • Deletion URL: $json:.delete$
6. The file sample_config.sxcu can also be modified & imported to suit your needs

Header overrides

If you need to override a specific part of the config to be different from the global config, you may do so via "X" HTTP headers:

Header	Purpose
X-Ass-Domain	Override the domain returned for the clipboard (useful for multi-domain hosts)
X-Ass-Access	Override the generator used for the resource URI. Must be one of: original, zws, or random (see above)

Fancy embeds

If you primarily share media on Discord, you can add these additional (optional) headers to build embeds:

Header	Purpose
X-Ass-OG-Title	Large text shown above your media
X-Ass-OG-Description	Small text shown below the title but above the media (does not show up on videos yet)
X-Ass-OG-Author	Small text shown above the title
X-Ass-OG-Color	Colour shown on the left side of the embed. Must be either a hex colour value (for example: #fe3c29) or &random

Embed placeholders

You can insert certain metadata into your embeds with these placeholders:

Placeholder	Result
&size	The files size with proper notation rounded to two decimals (example: 7.06 KB)
&filename	The original filename of the uploaded file
&timestamp	The timestamp of when the file was uploaded (example: Oct 14, 1983, 1:30 PM)
