How can I customize the appearance of the Basic Telegram Bot template?
You can customize the appearance of the Basic Telegram Bot template by modifying the HTML and CSS files. For example, to change the app name and color scheme, you would edit the header.html file:
html
<a id="appName" class="navbar-brand d-flex align-items-center" href="{{ url_for('home') }}">
<svg class="telegram-icon" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
<path fill="#your-color-here" d="M12 0C5.373 0 0 5.373 0 12s5.373 12 12 12 12-5.373 12-12S18.627 0 12 0zm5.562 8.248l-2.17 10.234c-.163.77-.766.98-1.552.61l-4.282-3.158-2.066 1.988c-.23.23-.423.423-.863.423l.308-4.374 7.956-7.187c.346-.308-.076-.48-.538-.172L7.04 12.656l-4.22-1.32c-.918-.288-.935-.918.192-1.36l16.48-6.35c.768-.288 1.438.172 1.19 1.36z"/>
</svg>
<span style="color: #your-color-here;">Your App Name</span>
</a>
You would also update the styles.css file to change the overall color scheme and layout.
How do I add new functionality to the Basic Telegram Bot template?
To add new functionality to the Basic Telegram Bot template, you'll need to modify both the Python backend and the HTML/JavaScript frontend. For example, to add a new command that responds with the current time, you would add this to the main.py file:
```python from datetime import datetime
def current_time(update: Update, context: CallbackContext) -> None: now = datetime.now().strftime("%H:%M:%S") update.message.reply_text(f"The current time is: {now}")
# In the setup_telegram_bot function: dispatcher.add_handler(CommandHandler("time", current_time)) ```
Then, you might add a button to request the time in your index.html:
html
<button id="timeButton" class="btn btn-primary">Get Current Time</button>
And handle it with JavaScript:
javascript
document.getElementById('timeButton').addEventListener('click', function() {
Telegram.WebApp.sendData("/time");
});
This demonstrates how the Basic Telegram Bot template can be extended with new features on both the bot and web app sides.

Introduction
The Basic Telegram Bot template provides a starting point for creating a Telegram mini app and bot. This template includes a simple web interface and a Telegram bot that can be easily customized to suit your needs.
Getting Started
To begin using this template:
- Click the "Start with this Template" button in the Lazy Builder interface.
Initial Setup
Before running the bot, you need to set up a Telegram Bot API Token:
- Open Telegram and search for the BotFather (@BotFather).
- Start a chat with BotFather and send the command
/newbot. - Follow the prompts to create a new bot. Choose a name and username for your bot.
- Once created, BotFather will provide you with an API token. Copy this token.
- In the Lazy Builder, go to the "Env Secrets" tab.
- Find the
TELEGRAM_API_TOKENsecret and paste your API token as its value.
Test the Application
After setting up the API token:
- Click the "Test" button in the Lazy Builder interface to deploy and run the application.
- The Lazy CLI will appear, showing the deployment progress.
Using the Bot
Once the bot is running:
- The CLI will display a message with your bot's username and a link to start chatting with it.
- Click the link or search for your bot's username in Telegram to start a conversation.
- Send the
/startcommand to the bot. It will respond with a message and a button to open the web app.
Using the Web App
The web app provides a simple interface for users:
- Click the "Open Web App" button in the Telegram chat to launch the web app.
- The app will open within Telegram, showing a basic interface.
- You can navigate to the Profile page to see your Telegram user information.
Customizing the App
To customize the app for your needs:
- Modify the
index.htmlfile to add your desired functionality to the main page. - Update the app name in the
header.htmlfile to reflect your bot's name. - Add new routes or modify existing ones in the
web_app_routes.pyfile to create new pages or API endpoints. - Customize the bot's responses by modifying the handler functions in
main.py.
Integrating the App
This template creates a standalone Telegram bot and mini app. There's no need for additional external integration steps. Users can interact with your bot directly through Telegram and access the web app via the bot's interface.
Remember to thoroughly test your bot and web app functionality after making any changes. You can always redeploy your app using the "Test" button in the Lazy Builder to see your updates in action.
