# Metar RSS Generator
This node app generates rss XML files that you can then serve as an RSS feed.

## Install and Setup (Linux)
```sh
# Clone the repo and install modules 
sudo mkdir -p /opt
cd /opt && sudo git clone https://git.entropic.pro/Aiden/metar-rss
npm i

# Edit config, see below for details
sudo nano /opt/metar-rss/config.json

# Create service user
sudo useradd -M metar-rss
sudo usermod -L metar-rss

# Create needed directories and ensure they are owned by the user
sudo mkdir -p /var/www/weather
sudo chmod -R metar-rss:metar-rss /var/www/weather
sudo chmod -R metar-rss:metar-rss /opt/metar-rss

# Install and start service (systemd)
sudo cp /opt/metar-rss/metar-rss.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now metar-rss.service 
```

## 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.
