javascript - Use bold tag to send my message from node server

Question

I want to use Bold tag example: <b>Hiii</b> to send my messages to user on running of node server.

I am using : npm Tgfancy

Node

const chatId = '-xxxxxx';

const token = '566470572:ffffff';

const bot = new Tgfancy(token, {
    // all options to 'tgfancy' MUST be placed under the
    // 'tgfancy' key, as shown below
    tgfancy: {
        option: "value",
    },
});

bot.sendMessage(parse_mode='HTML', chatId, replyText);

How can I parse HTML with that?

I have my content but its not tagging with bold or any other HTML tags.

My code

var replyText = " Signal #"+coinName+ " has reached 1st target! " +profit+ "% profit 
Current Price:" +liveCoinPrice+ "
Duration: " +difference + "
Note: Message from live coin high node server";

Here, I want to bold coinName, profit, etc.

Output

Any help would be thankful.

Answer 1

This worked for parse_mode = "HTML".

https://github.com/yagop/node-telegram-bot-api/issues/108

var replyText = "Signal #" + coinName.bold() + " has reached 2nd target! " + profit.bold() + "% profit 
Current Price: " + liveCoinPrice.bold() + "
Duration: " + difference.bold();

var option = {
  "parse_mode": "HTML",
};

bot.sendMessage(msg.chat.id, replyText, option);
