RSSHub Smart Layer

An enhancement overlay for RSSHub

Modules

• Load Balance
• Machine Translate
• Image Proxy

Workflow

1. Request RSSHub endpoint (through JSON format) till one success, or 503
2. (Optional) Send to machine translate and cache results
3. (Optional) Apply image proxy rules
4. Re-construct feed to target format

Configuration

Configuration is combined of 4 parts: system, rsshub, translate and image_proxy. An example can be referred from config.yml.example.

1. system part defines the basic info of this application, every field is required.
2. rsshub part defines all RSSHub instance and their corresponding preferences (preferred platforms and whether it can work as a fallback instance). Different RSSHub has different configuration options, so offload different requests to different instances effectively should be helpful. Or if just one single RSSHub instance is provided, skip platforms field and set fallback to true to handle all incoming requests.
3. translate defines the service provider and other request details. We are using subdomain to identify target language to provide a smooth experience for end users, which is configured by host_base: in example configuration, our translate-enabled domain is *.rsl.localhost. For example, if we request zh.rsl.locahost, then zh will be select as target language. Different translate provider has different settings, for libretranslate we are using YAML format. Please refer to different provider settings.
4. image_proxy provides a simple image proxy service to bypass image protect mechanisms. To provide more flexibility, we don't pre-define any built-in rules here, please add your own rules for different platforms.

Only system and rsshub parts are required, if you don't want translate or image_proxy function, simply delete them.

Tech spec

Load Balance

Based on random numbers.

Maybe add redis based load-balance in the future.

Translate

Supported Translate Providers

• LibreTranslate

Add more provider

1. Copy modules/translate/providers/libretranslate directory and rename to your target provider
2. Update relative codes (settings, initializer, translate func)
3. Update modules/translate/providers/new.go func, add your provider

Image Proxy

Currently only Origin and Referer can be specified.

Maybe add more options in the future.

Response format

Follows RSSHub format query, currently 3 formats:

• rss: RSS 2.0 (default / fallback)
• atom: Atom
• json: JSON Feed
