    }
}
```

### Install with Docker:

### Alternative installation methods

[![Deploy on Scalingo](https://cdn.scalingo.com/deploy/button.svg)](https://my.scalingo.com/deploy?source=https://github.com/sebsauvage/rss-bridge)
[![Deploy to Heroku](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)
[![Deploy to Cloudron](https://cloudron.io/img/button.svg)](https://www.cloudron.io/store/com.rssbridgeapp.cloudronapp.html)

The Heroku quick deploy currently does not work. It might possibly work if you fork this repo and
modify the `repository` in `scalingo.json`. See https://github.com/RSS-Bridge/rss-bridge/issues/2688

[Installation](https://rss-bridge.github.io/rss-bridge/For_Hosts/Installation.html).

### Create a new bridge from scratch

Create the new bridge in e.g. `bridges/BearBlogBridge.php`:

```php
<?php

class BearBlogBridge extends BridgeAbstract
{
    const NAME = 'BearBlog (bearblog.dev)';

    public function collectData()
    {
        // We can perform css selectors on $dom
        $dom = getSimpleHTMLDOM('https://herman.bearblog.dev/blog/');

        // An array of dom nodes
        $blogPosts = $dom->find('.blog-posts li');

        foreach ($blogPosts as $blogPost) {
            // Select the anchor at index 0 (the first anchor found)
            $a = $blogPost->find('a', 0);

            // Select the inner text of the anchor
            $title = $a->innertext;

            // Select the href attribute of the anchor
            $url = $a->href;

            // Select the <time> tag
            $time = $blogPost->find('time', 0);
            // Create a \DateTime object from the datetime attribute
            $createdAt = date_create_from_format('Y-m-d', $time->datetime);

            $item = [
                'title' => $title,
                'author' => 'Herman',

                // Prepend the url because $url is a relative path
                'uri' => 'https://herman.bearblog.dev' . $url,

                // Grab the unix timestamp
                'timestamp' => $createdAt->getTimestamp(),
            ];

            // Add the item to the list of items
            $this->items[] = $item;
        }
    }
}
```

RSS-Bridge uses caching to prevent services from banning your server for repeatedly updating feeds.
The specific cache duration can be different between bridges. Cached files are deleted automatically after 24 hours.

RSS-Bridge allows you to take full control over which bridges are displayed to the user.
That way you can host your own RSS-Bridge service with your favorite collection of bridges!

Supported output formats:

* `Atom` : Atom feed, for use in feed readers
* `Html` : Simple HTML page
* `Json` : JSON, for consumption by other applications
* `Mrss` : MRSS feed, for use in feed readers
* `Plaintext` : Raw text, for consumption by other applications

## Rant

*Dear so-called "social" websites.*

Your catchword is "share", but you don't want us to share. You want to keep us within your walled gardens. That's why you've been removing RSS links from webpages, hiding them deep on your website, or removed feeds entirely, replacing it with crippled or demented proprietary API. **FUCK YOU.**

You're not social when you hamper sharing by removing feeds. You're happy to have customers creating content for your ecosystem, but you don't want this content out - a content you do not even own. Google Takeout is just a gimmick. We want our data to flow, we want RSS or Atom feeds.

We want to share with friends, using open protocols: RSS, Atom, XMPP, whatever. Because no one wants to have *your* service with *your* applications using *your* API force-feeding them. Friends must be free to choose whatever software and service they want.

We are rebuilding bridges you have willfully destroyed.

Get your shit together: Put RSS/Atom back in.
