Discord will only create embeds for videos and images if they are smaller than 10MiB. We can "abuse" this by using the twitter:image HTML meta tag.
This is useful when you send a video and want it to be playable in Discord.
This program will create a .html that you will send instead of a .mp4 file. Discord will parse the HTML and create an embed for you. The embed will be the same as the one you would get if you send a .mp4 file.
| Variable | Description |
|---|---|
| SERVE_DOMAIN | Domain where we server files from, not where we upload files to. |
| UPLOAD_FOLDER | Path to the directory where we store files. |
| WEBHOOK_URL | Discord Webhook URL |
| SENTRY_DSN | Optional. Overrides the Sentry DSN. Set to an empty string ("") to disable crash reporting. |
This project is meant to be used with Docker. You can find a docker-compose.yml file in this repository.
We have to do some URL rewriting to make this work. You can find examples for Nginx and Caddy below.
You have two example files here: embed.subdomain.conf and i.subdomain.conf
- embed.subdomain.conf
- This is the file you will use for the subdomain where you will upload files to.
- i.subdomain.conf:
- This is the file you will use for the subdomain where you will serve files from.
# SERVE_DOMAIN = i.example.com
# UPLOAD_FOLDER = /var/www/embed
embed.example.com {
reverse_proxy * http://discord-embed:5000 # The Docker container where discord-embed runs
}
i.example.com {
root * /var/www/embed
try_files {uri} {uri}/ {uri}.html
file_server
}There is a ShareX.sxcu file in this repository. You can import it into ShareX and use it to upload files to your server. You will have to change the RequestURL to your own domain. (The domain where discord-embed runs).
It will return a JSON object with the URL to the file. This is the URL you will send in Discord.
