const { TelegramAPI } = require("teletron-ts"); // Individual classes

Getting started

import { TelegramAPI } from "teletron-ts";

const telegram = new TelegramAPI("token"); // bot token api

// listen for the message event

telegram.onMessage(async (message) => {
  if (message.text === "Hi bot!")
    await telegram.sendMessage(message.chat.id, "Hi there, human!"); // sendMessage will return an instance of IMessage
});

Telegram Events

Events you can listen to usign teletron-ts:

  • message
  • edited_message

  • chosen_inline_result
  • callback_query

Examples

Sending Files

There are 3 ways to send files. You can use the file id of a file that already exist on telegram servers, provide an HTTP URL to the file which then will be downloaded by telegram servers or upload a local file. Lets assume we want to send a photo via the bot:

import { TelegramAPI } from "teletron-ts";

const telegram = new TelegramAPI("token"); // bot token

telegram.on("message", async (message) => {
  // First Method: Using an already existing file_id of a file that has been previously uploaded on telegram
  await telegram.sendPhoto(
    message.chat.id,
    "AgADBQADqacxG2gbbxCWBkgvcmeAgxVPyjIABBlug37DKyhDEU0AAgI"
  );

  // Second Method: Using an HTTP photo url
  await telegram.sendPhoto(
    message.chat.id,
    "https://reshape.sport1.de/c/t/85599615-c80d-47f0-9179-4375d6e4fa93/976x549"
  );

  // Thrid Method: Using a local file
  await telegram.sendPhoto(message.chat.id, { file: "./anime.jpg" });
});

// fetch updates from the api
telegram.startPolling();

Inline Keyboards

Inline keyboards are buttons that will be sent along with the message. These become especially useful if you want to wait for user input to perform certain action!

import { TelegramAPI } from "teletron-ts";
import { IInlineKeyboardMarkup } from "teletron-ts";

const telegram = new TelegramAPI("token");

telegram.on("message", async (m) => {
  const inlineKeyboards: IInlineKeyboardMarkup = {
    inline_keyboard: [
      [
        { text: "Very Good!", callback_data: "vgood" },
        { text: "Fine", callback_data: "fine" },
      ],
      [{ text: "Amazing", callback_data: "amazing" }],
    ],
  };

  await telegram.sendMessage(
    m.chat.id,
    "Hey there, how are you feeling today?",
    {
      reply_markup: JSON.stringify(inlineKeyboards),
    }
  );
});

telegram.on("callback_query", async (query) => {
  if (query.data && query.data === "vgood")
    return await telegram.sendMessage(
      query.message.chat.id,
      "I am feeling very good today too!"
    );
});
