> Instance-agnostic share page for the Fediverse.

**[Share₂Fedi]** allows you to share stuff on Mastodon, GoToSocial, Pleroma, 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:

```html
<a
  href="https://s2f.kytta.dev/?text=Hello%20world!&instance=https%3A%2F%2Fmastodon.xyz"
>
  Share on mastodon.xyz
</a>
```

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

## Hosting

### One-click Vercel deploy

**Share₂Fedi** is designed to run on [Vercel](https://vercel.com/).
To deploy it yourself (it's free!), you can use the following button:

[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fkytta%2Fshare2fedi)

### Host it yourself

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

**Prerequisites:** modern Node.js (v16 or later), `pnpm`.

1. Install the dependencies:

   ```sh
   pnpm install
   ```

2. Build the static files:

   ```sh
   pnpm build
   ```

3. Run the backend server for the form:

   ```sh
   node api/share.js
   ```

   alternatively, if you want to run the process in the background:

   ```sh
   pm2 start api/share.js --watch --ignore-watch="node_modules"
   ```

   > You can find a summary for pm2 at: https://pm2.keymetrics.io/docs/usage/quick-start/

4. Set up a web server

   Basically, you need to run a server that would proxy the requests to `/api/share`.
   to the Node.js server you started. Here's how to achieve this in various HTTP
   servers:

   1. Apache

   ```apacheconf
   DocumentRoot "<PATH_TO_SHARE2FEDI>/dist"

   ProxyPass "/api/share"  "http://localhost:8080/"
   ```

   2. Nginx

   ```nginxconf
   root <PATH_TO_SHARE2FEDI>/dist;
   index.html;

   location /api/share {
       proxy_pass http://localhost:8080/;
   }
   ```

   3. Caddy

   ```caddy
   root * <PATH_TO_SHARE2FEDI>/dist;
   try_files index.html

   handle_path /api/share {
      reverse_proxy localhost:8080
   }
   ```
