## Tutorial
|
|
|
|
### How to install on traditional shared web hosting
|
|
|
|
RSS-Bridge can basically be unzipped in a web folder. Should be working instantly.
|
|
|
|
Latest zip as of Sep 2023: https://github.com/RSS-Bridge/rss-bridge/archive/refs/tags/2023-09-24.zip
|

|
### How to install on Debian 12 (nginx + php-fpm)
|
|
|
|
These instructions have been tested on a fresh Debian 12 VM from Digital Ocean (1vcpu-512mb-10gb, 5 USD/month).
|
|
|
|
```shell
|
|
timedatectl set-timezone Europe/Oslo
|
|
|
|
apt install git nginx php8.2-fpm php-mbstring php-simplexml php-curl php-intl
|
|
|
|
# Create a new user account
|
|
useradd --shell /bin/bash --create-home rss-bridge
|
|
|
|
cd /var/www
|
|
|
|
# Create folder and change ownership
|
|
mkdir rss-bridge && chown rss-bridge:rss-bridge rss-bridge/
|
|
|
|
# Become user
|
|
su rss-bridge
|
|
|
|
# Fetch latest master
|
|
git clone https://github.com/RSS-Bridge/rss-bridge.git rss-bridge/
|
|
cd rss-bridge
|
|
|
|
# Copy over the default config
|
|
cp -v config.default.ini.php config.ini.php
|
|
|
|
# Give full permissions only to owner (rss-bridge)
|
|
chmod 700 -R ./
|
|
|
|
# Give read and execute to others (nginx and php-fpm)
|
|
chmod o+rx ./ ./static
|
|
|
|
# Give read to others (nginx)
|
|
chmod o+r -R ./static
|
|
```
|

## How-to
|
|
|
|
### How to fix "Access denied."
|
|
|
|
Output is from php-fpm. It is unable to read index.php.
|
|
|
|
chown rss-bridge:rss-bridge /var/www/rss-bridge/index.php
|
|
|
|
### How to password-protect the instance (token)
|
|
|
|
Modify `config.ini.php`:
|
|
|
|
[authentication]
|
|
|
|
token = "hunter2"
|
|
|
|
### How to remove all cache items
|
|
|
|
As current user:
|
|
|
|
bin/cache-clear
|
|
|
|
As user rss-bridge:
|
|
|
|
sudo -u rss-bridge bin/cache-clear
|
|
|
|
As root:
|
|
|
|
sudo bin/cache-clear
|
|
|
|
### How to remove all expired cache items
|
|
|
|
bin/cache-prune
|
|
|
|
### How to fix "PHP Fatal error: Uncaught Exception: The FileCache path is not writable"
|
|
|
|
```shell
|
|
# Give rss-bridge ownership
|
|
chown rss-bridge:rss-bridge -R /var/www/rss-bridge/cache
|
|
|
|
# Or, give www-data ownership
|
|
chown www-data:www-data -R /var/www/rss-bridge/cache
|
|
|
|
# Or, give everyone write permission
|
|
chmod 777 -R /var/www/rss-bridge/cache
|
|
|
|
# Or last ditch effort (CAREFUL)
|
|
rm -rf /var/www/rss-bridge/cache/ && mkdir /var/www/rss-bridge/cache/
|
|
```
|
|
|
|
### How to fix "attempt to write a readonly database"
|
|
|
|
The sqlite files (db, wal and shm) are not writeable.
|
|
|
|
chown -v rss-bridge:rss-bridge cache/*
|
|
|
|
### How to fix "Unable to prepare statement: 1, no such table: storage"
|
|
|
|
rm cache/*
|
|
|
|
### How to 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()
|
|
{
|
|
$dom = getSimpleHTMLDOM('https://herman.bearblog.dev/blog/');
|
|
foreach ($dom->find('.blog-posts li') as $li) {
|
|
$a = $li->find('a', 0);
|
|
$this->items[] = [
|
|
'title' => $a->plaintext,
|
|
'uri' => 'https://herman.bearblog.dev' . $a->href,
|
|
];
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Learn more in [bridge api](https://rss-bridge.github.io/rss-bridge/Bridge_API/index.html).
|
|
|
|
### How to enable all bridges
|
|
|
|
enabled_bridges[] = *
|
|
|
|
### How to enable some bridges
|
|
|
|
```
|
|
enabled_bridges[] = TwitchBridge
|
|
enabled_bridges[] = GettrBridge
|
|
```
|
|
|
|
### How to enable debug mode
|
|
|
|
The
|
|
[debug mode](https://rss-bridge.github.io/rss-bridge/For_Developers/Debug_mode.html)
|
|
disables the majority of caching operations.
|
|
|
|
enable_debug_mode = true
|
|
|
|
### How to switch to memcached as cache backend
|
|
|
|
```
|
|
[cache]
|
|
|
|
; Cache backend: file (default), sqlite, memcached, null
|
|
type = "memcached"
|
|
```
|
|
|
|
### How to switch to sqlite3 as cache backend
|
|
|
|
type = "sqlite"
|
|
|
|
### How to disable bridge errors (as feed items)
|
|
|
|
When a bridge fails, RSS-Bridge will produce a feed with a single item describing the error.
|
|
|
|
This way, feed readers pick it up and you are notified.
|
|
|
|
If you don't want this behaviour, switch the error output to `http`:
|
|
|
|
[error]
|
|
|
|
; Defines how error messages are returned by RSS-Bridge
|
|
;
|
|
; "feed" = As part of the feed (default)
|
|
; "http" = As HTTP error message
|
|
; "none" = No errors are reported
|
|
output = "http"
|
|
|
|
### How to accumulate errors before finally reporting it
|
|
|
|
Modify `report_limit` so that an error must occur 3 times before it is reported.
|
|
|
|
; Defines how often an error must occur before it is reported to the user
|
|
report_limit = 3
|
|
|
|
The report count is reset to 0 each day.
|
|
|
|
### How to password-protect the instance (HTTP Basic Auth)
|
|
|
|
[authentication]
|
|
|
|
enable = true
|
|
username = "alice"
|
|
password = "cat"
|
|
|
|
Will typically require feed readers to be configured with the credentials.
|
|
|
|
It may also be possible to manually include the credentials in the URL:
|
|
|
|
https://alice:cat@rss-bridge.org/bridge01/?action=display&bridge=FabriceBellardBridge&format=Html
|
|
|
|
### How to create a new output format
|
|
|
|
See `formats/PlaintextFormat.php` for an example.
|
|
|
|
### How to run unit tests and linter
|
|
|
|
These commands require that you have installed the dev dependencies in `composer.json`.
|
|
|
|
./vendor/bin/phpunit
|
|
./vendor/bin/phpcs --standard=phpcs.xml --warning-severity=0 --extensions=php -p ./

|
|
|
|
php -S 127.0.0.1:9001

## Explanation
|
|
|
|
We are RSS-Bridge community, a group of developers continuing the project initiated by sebsauvage,
|
|
webmaster of
|
|
[sebsauvage.net](https://sebsauvage.net), author of
|
|

|
|
|
|
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!

## Reference
|
|
|
|
### Feed item structure
|
|
|
|
This is the feed item structure that bridges are expected to produce.
|
|
|
|
```php
|
|
$item = [
|
|
'uri' => 'https://example.com/blog/hello',
|
|
'title' => 'Hello world',
|
|
// Publication date in unix timestamp
|
|
'timestamp' => 1668706254,
|
|
'author' => 'Alice',
|
|
'content' => 'Here be item content',
|
|
'enclosures' => [
|
|
'https://example.com/foo.png',
|
|
'https://example.com/bar.png'
|
|
],
|
|
'categories' => [
|
|
'news',
|
|
'tech',
|
|
],
|
|
// Globally unique id
|
|
'uid' => 'e7147580c8747aad',
|
|
]
|
|
```
|
|
|
|
### 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
|
|
* `Sfeed`: Text, TAB separated
|
|
|
|
### Cache backends
|
|
|
|
* `File`
|
|
* `SQLite`
|
|
* `Memcached`
|
|
* `Array`
|
|
* `Null`
|
|

## 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.
|
