Televerse lets you create your own efficient Telegram bots with ease in Dart. Supports latest Telegram Bot API - 6.5!

Televerse

Televerse is simple & efficient way to create Telegram bots with Dart.

🤖 Bot API version: Bot API 6.6 (March 9, 2023)

👨🏻‍💻 Installation

Add this to your package's pubspec.yaml file:

dependencies:
  televerse: <latest>

📖 Usage

With Televerse you can create a simple bot in just a few lines of code:

import 'package:televerse/televerse.dart';

Bot bot = Bot('YOUR_BOT_TOKEN');

Now with the bot instance you can start listening for updates such as messages, commands, etc.

To start polling updates from Telegram servers, you need to call:

bot.start()

From, Televerse 1.3.1, you can use bot.start method to start listening for updates and also, setup a command listener for the /start command.

That is you can shrink this code:

bot.command('start', (ctx) {
  ctx.reply('Hello, World!');
});

bot.start();

To this:

bot.start((ctx) {
  ctx.reply('Hello, World!');
});

📚 Documentation

📖 Televerse Wiki

We have a dedicated documentation on GitHub Wiki on this repo. Check it our here: Televerse Wiki.

✨ In simple words

Starting from version 1.4.0, Televerse has a new API that is much simpler and easier to use. You can now use the bot instance to access the powerful Televerse methods and properties, and if you want to access the Telegram Bot API methods, you can use the bot.api getter. Simple, and clean.

Now, when you're inside a callback function, you can access the bot instance using the MessageContext parameter which also provides you with the api property.

For example, if you want to send a message to a specific chat you can do it like this:

bot.api.sendMessage(ChatID(123456), "Hello, World!");

// or with the context

ctx.api.sendMessage(ChatID(123456), "Hello, World!");

👽 Advanced Usage

We also provide a set of custom methods to make your life easier. Some of them are:

• bot.command to listen for commands
• bot.chatType and bot.chatTypes to listen for specific chat types
• bot.text to listen for text messages that contains a specific text

And even advanced methods like

• bot.filter to create your own filters and listen for messages that match them
• bot.hear to listen for messages that match a RegExp

Filter and hear methods are very powerful and can be used to create your own custom filters.

For example, if you want to listen for messages that contains a photo which has more than 1MB of size, you can do it like this:

bot.filter((ctx) {
  return (ctx.message.photo?.last.fileSize ?? 0) > 1000000;
}, (ctx) {
  ctx.reply('Wow, that\'s a big photo!');
});

Note: we're still working on improving the documentation, so you can check the example file for more information.

🔐 Example

You can find a simple example of a bot that uses Televerse in the example file.

👽 Examples Repo

But, where's the fun in that? So we've created an entire repository with examples of bots built with Televerse. Check it out here: Televerse Examples.

This repository includes examples of bots such as simple letter counting bot to referral bot, and many more on the way. Moreover, we've detailed the code and explained how it works, so you can learn how to build your own bots with Televerse.

📝 Note

We're still at the early stages of the project, so we're working on improving the documentation and adding more features.
