Telegram bot which repeats send message with some time?

Question

ClearInterval don't work or work but I make a mistake. I don't know but when I use /stop it continue write 'Sending'. How to resolve such problem.

 bot.hears(/\/send|\/stop/, ctx=> { let sending = setInterval(() => { if (/\/send/.test(ctx.update.message.text)) { ctx.reply('Sending:'); } else if (/\/stop/.test(ctx.update.message.text)){ ctx.reply('stopping;'); clearInterval(sending), } }; 10000); });

Answer 1

The main problem is you're creating new intervals every time you send /send or /stop . So, your intervals get created multiple times generating multiple intervals in parallel.

Something like this should work:

let sendInterval;
bot.hears(/\/send|\/stop/, ctx => {
  if (sendInterval) {
    clearInterval(sendInterval);
  }

  if (/\/send/.test(ctx.update.message.text)) {
    sendInterval = setInterval(() => {
      ctx.reply('Sending');
    }, 10000);
  } else if (/\/stop/.test(ctx.update.message.text)) {
    ctx.reply('stopping!');
  }
});
