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.
Gfycat	Gfycat-style ID's (for example: https://gfycat.com/unsungdiscretegrub "unsung discrete grub")
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: $json:.resource$
   • Thumbnail: $json:.thumbnail$
   • Deletion URL: $json:.delete$
   • MagicCap users: do not include the . in the above (i.e. $json:resource$)
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, gfycat, or random (see above)
X-Ass-Gfycat	Override the length of Gfycat ID's. Defaults to 2

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-Author-Url	URL to open when the Author is clicked
X-Ass-OG-Provider	Smaller text shown above the author
X-Ass-OG-Provider-Url	URL to open when the Provider is clicked
X-Ass-OG-Color	Colour shown on the left side of the embed. Must be one of &random, &vibrant, or a hex colour value (for example: #fe3c29). Random is a randomly generated hex value and Vibrant is sourced from the image itself

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)

Webhooks

You may use Discord webhooks as an easy way to keep track of your uploads. The first step is to create a new Webhook. You only need to follow the first section, Making a Webhook. Once you are done that, click Copy Webhook URL. Next, paste your URL into a text editor. Extract these two values from the URL:

https://discord.com/api/webhooks/12345678910/T0kEn0fw3Bh00K
                                 ^^^^^^^^^^  ^^^^^^^^^^^^ 
                                 Webhook ID  Webhook Token

Once you have these, add the following HTTP headers to your ShareX config:

Header	Purpose
X-Ass-Webhook-Client	The Webhook ID
X-Ass-Webhook-Token	The Webhook Token
X-Ass-Webhook-Username	(Optional) the "username" of the Webhook; can be set to whatever you want
X-Ass-Webhook-Avatar	(Optional) URL to an image to use as the Webhook avatar. Use the full URL including https://

Webhooks will show the filename, mimetype, size, upload timestamp, thumbail, and a link to delete the file. To disable webhooks, simply remove the headers from your config.
