Download YouTube Videos and Audios with Node.js

The code you provided is incomplete and contains some errors. Here is the corrected version:

const youtube = require('yt-search');
const btch = require('btch-downloader');

let handler = async (m, { conn, text, command }) => {
  if (!text) throw 'Enter Title / Link From YouTube!';
  conn.reply(m.chat, 'Please wait...', m);
  
try {
    var search = await youtube(text);
    var convert = search.videos[0];
    if (!convert) throw 'Video/Audio Tidak Ditemukan';
    
if (convert.seconds >= 3600) {
      conn.reply(m.chat, 'Video is longer than 1 hour!', m);
    } else {
      var video;
      try {
        video = await btch.youtube(convert.url);
      } catch (e) {
        conn.reply(m.chat, 'Please wait...', m);
        video = await btch.youtube(convert.url);
      }
      
      var audio = `https://yt.tioo.eu.org/youtube?url=${convert.url}`;
      // do something with video and audio
    }
  } catch (error) {
    console.log(error);
    conn.reply(m.chat, 'An error occurred.', m);
  }
};

module.exports = {
  commands: ['youtube'],
  handler
};

Please note that you need to handle the video and audio variables appropriately according to your use case.
