Node RSS Proxy
Node RSS Proxy is a node.js service I use on my linode server to proxy and cache podcast RSS feeds.
Why? To reduce mobile data usage, and so my phone can process RSS feeds more quickly.
- The proxy reduces the size of a podcast feed by omitting unnecessary XML elements
- Reduces the number of servers my phone has to contact when fetching feeds
- Returns only the new feed items (since podcast client's last fetch)
- Follows feed redirects, and remembers previous URLs
- NPM modules: See the "npm install" line below
Installation and Usage:
- npm install
- Installs mysql feedparser request entities node-statsd-client
- Create a mysql database
- Use setup.mysql to create tables
- Copy config-example.js to config.js and update with your database credentials and desired secret folder prefix
- Start the service on port 80 via: node ./index.js 80
- Note: It's probably best to use a higher port so you can run as non-root. Then use port forwarding or configure a proxy in nginx/lighttpd/apache
- When adding feeds to your podcast client, prepend feed URL with: http://YOURDOMAIN.com/FOLDERSECRET-CLIENTNAME/
- FOLDERSECRET is a secret folder prefix of your choosing, to keep others from using your proxy
- CLIENTNAME is to differentiate devices/podcast-clients
Note about Caddy HTTP server:
Caddy convert an invalid URL info a valid one, which caused problems for the proxy. Caddy will convert this:
To accomodate that, I've modified src/index.js to expand "http/" into "http://" as appropriate.
