> 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` and
`lang` URL parameters. 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=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](https://s2f.kytta.dev) 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](https://vercel.com/), but you can
also run it on [Netlify](https://www.netlify.com/) or
[Cloudflare Pages](https://pages.cloudflare.com/). To deploy it yourself (it's
free!), you can use the following buttons:
[![Deploy to Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fkytta%2Fshare2fedi)
[![Deploy to Netlify](https://www.netlify.com/img/deploy/button.svg)](https://app.netlify.com/start/deploy?repository=https://github.com/kytta/share2fedi)
To deploy to Cloudflare Pages, fork the repository and
[follow the instructions](https://docs.astro.build/en/guides/deploy/cloudflare/#how-to-deploy-a-site-with-git).
### Host it yourself
Self-hosting Share₂Fedi outside of SSR providers requires some extra setup:
**Prerequisites:** modern Node.js (v18 is recommended), `pnpm`. You can host
with Deno, but Node.js is still required to build Share₂Fedi.
1. Install dependencies.
```sh
pnpm install
```
2. Build.
```sh
pnpm build
```
If you want to use Deno, add the `--s2f-use-deno` flag:
```sh
pnpm build --s2f-use-deno
```
3. Run server.
> By default, this will only listen on localhost port 3000. To enable
> listening on a certain host and/or port, set the `HOST` and `PORT`
> environment variables, respectively.
```sh
node dist/server/entry.mjs
```
In production, you might want to use a process manager, like
[PM2](https://pm2.keymetrics.io/docs/usage/quick-start/):
```sh
# Start the app, restart on file changes (except node_modules)
pm2 start dist/server/entry.mjs --name "Share2Fedi" --watch --ignore-watch="node_modules"
```

> https://docs.astro.build/en/guides/integrations-guide/node/#standalone
If you've built Share₂Fedi for Deno:
```sh
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
```apacheconf
ProxyPass "/" "http://localhost:3000/"
```
2. Nginx
```nginxconf
location / {
proxy_pass http://localhost:3000/;
}
```
3. Caddy
```caddy
reverse_proxy :3000
```
### Docker
If you _really_ have to use Docker, there is
[a good guide on building Astro apps with Docker](https://docs.astro.build/en/recipes/docker/).
**I will not** provide support for Docker-based deployments in the observable
future.
