Context Object

From each function in config.js you can access a context object containing the following data:

• channel: The object describing the current channel (xmltv_id, site_id, name, lang)
• date: The 'dayjs' instance with the requested date
• content: The response data as a String
• buffer: The response data as an ArrayBuffer
• headers: The response headers
• request: The request config
• cached: A boolean to check whether this request was cached or not

Channels List

<?xml version="1.0" ?>
<channels site="example.com">
  <channel site_id="cnn-23" xmltv_id="CNN.us">CNN</channel>
  ...
</channels>

You can also specify the language, site and logo for each channel individually, like so:

<channel
  site="example.com"
  site_id="france-24"
  xmltv_id="France24.fr"
  lang="fr"
  logo="https://example.com/france24.png"
>France 24</channel>

How to use SOCKS proxy?

First, you need to install socks-proxy-agent:

npm install socks-proxy-agent

Then you can use it to create an agent that acts as a SOCKS proxy. Here is an example of how to do it with the Tor SOCKS proxy:

const { SocksProxyAgent } = require('socks-proxy-agent')

const torProxyAgent = new SocksProxyAgent('socks://localhost:9050')

module.exports = {
  site: 'example.com',
  url: 'https://example.com/epg.json',
  request: {
    httpsAgent: torProxyAgent,
    httpAgent: torProxyAgent
  },
  parser(context) {
    // ...
  }
}
