Config

The following settings can be set in config.json:

outputdir
- This is the base directory where the RSS XML files will be output
icaos
- This is an array of ICAO Airport codes to generate feeds for.
siteurl
- This should be the base url for your website
rss-baseurl
- This should be the base url path where these files will be served.
  - Eg. https://example.com/weather will indiate that KJFK's metar will be served at https://example.com/weather/metar/KJFK/rss.xml
check-interval
- This sets how often the app will check for new data in minutes
loglevel
- Uses standard loglevel values, set 7 or higher for all logs (debug)

Webserver

Note that this app only generates the rss files, you will still need to serve them with some kind of webserver, I have included an example caddy configuration for referance.
