Instance-agnostic share page for the Fediverse.

Share₂Fedi (pronounced ‘share-to-fedi’) allows you to share stuff on Mastodon, Misskey, Friendica, and other federated social networks, instance-agnostic. Just type in the post text and the instance URL, and click ‘Post!’

Or, open this page with the prefilled text URL parameter—it will be automatically inserted into the text field. The same goes for the instance URL parameter. This can be used to build custom share buttons for the federated social networks:

<a href="https://s2f.kytta.dev/?text=Hello%20world!&instance=mastodon.xyz">
  Share on mastodon.xyz
</a>

The instance URL can be saved in your localStorage to be automatically appended if used later—handy!

Important

I know I provide a Share₂Fedi instance for others to use, but if you want to use Share₂Fedi for your share buttons, please consider self-hosting it. Although it's free now, running my instance may become too expensive for me in the future.

Hosting

Vercel, Netlify, Cloudflare Pages

Share₂Fedi was designed to run on Vercel, but you can also run it on Netlify or Cloudflare Pages. To deploy it yourself (it's free!), you can use the following buttons:

To deploy to Cloudflare Pages, fork the repo and follow the instructions.

Host it yourself

Self-hosting Share₂Fedi outside of Vercel requires some extra setup:

Prerequisites: modern Node.js (v16 or later), pnpm. You can host with Deno, but Node.js is still required.

1. Install dependencies.

   pnpm install
   

2. Build.

   pnpm build
   

   If you want to use Deno, add the --s2f-use-deno flag:

   pnpm build --s2f-use-deno
   

3. Run server.

   By default, this will only listen on localhost port 3000. To enable listening on a ceratin host and/or port, set the HOST and PORT environment variables, respectively.

   node dist/server/entry.mjs
   

   In production, you might want to use a process manager, like PM2:

   # Start the app, restart on file changes (except node_modules)
   pm2 start dist/server/entry.mjs --name "Share2Fedi" --watch --ignore-watch="node_modules"

   If you've built Share₂Fedi for Deno:

   deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs

4. Set up a reverse proxy.

   Basically, you need to run a reverse proxy that would redirect all incoming requests to localhost:3000. Here's how to achieve this in various HTTP servers:

   1. Apache

   ProxyPass "/" "http://localhost:3000/"
   

   2. Nginx

   location / {
       proxy_pass http://localhost:3000/;
   }
   

   3. Caddy

   reverse_proxy :3000
   

Docker

If you really have to use Docker, there is a good guide on building Astro apps with Docker. I will not provide support for Docker-based deployments in the observable future.
