Fix X/Twitter and Bluesky embeds! Use multiple images, videos, polls, translations and more on Discord, Telegram and others

FxEmbed is a Cloudflare Worker, so the Docker image runs the local Workers runtime through Wrangler rather than starting a plain Node.js server. The image uses node:24-bookworm-slim because Wrangler's workerd binary is glibc-linked and does not run reliably on Alpine/musl.

Before building, copy and edit the local configuration files if you need custom domains, branding, or credentials:

cp .env.example .env
cp wrangler.example.toml wrangler.toml
cp branding.example.json branding.json

Build and run with Docker Compose:

docker compose up -d --build

The worker listens on http://localhost:8787. Because FxEmbed routes by the Host header, test a specific realm like this:

curl -H "Host: fxtwitter.com" -H "User-Agent: Discordbot/2.0" "http://localhost:8787/user/status/123"

You can also open http://localhost:8787/ without a Host header to see the local realm prefixes.

Environment variables from .env are bundled during the Docker build, so rebuild the image after changing domain lists or other build-time configuration:

docker compose up -d --build

Runtime secrets such as CREDENTIAL_KEY and EXCEPTION_DISCORD_WEBHOOK can be supplied through your shell or Compose .env file. Stop the service with:

docker compose down
