Blog Article
Telegram Mini Apps can be a powerful feature with the Telegram platform that allow developers to construct seamless, interactive web applications that run in the Telegram interface. These apps give a smooth consumer experience and can cover anything from games and productivity tools to e-commerce storefronts and booking systems.
In this short article, we’ll walk you through the process of create mini app telegram from scratch.
???? What Is a Telegram Mini App?
Telegram Mini Apps are lightweight web apps launched inside Telegram chats via inline buttons or through bot commands. They are built using web related technologies (HTML, CSS, JavaScript) and interact with Telegram’s Bot API and Web Apps API.
These apps:
Run in Telegram's built-in browser
Can access user data (with permission)
Integrate seamlessly with Telegram bots
Support payment and authorization flows
????️ Tools & Prerequisites
Before starting out, you’ll need:
A Telegram account
A Telegram bot (via BotFather)
Basic web design knowledge (HTML, CSS, JS)
Hosting on your web app (e.g., Vercel, Netlify, or your individual server)
Optional tools:
Node.js (for backend logic)
Web frameworks like React or Vue
???? Step 1: Create a Telegram Bot
Open @BotFather on Telegram.
Use /newbot to produce a new bot.
Choose an identity and a username for your bot.
Copy the API token provided — you’ll want it to communicate with Telegram’s servers.
???? Step 2: Build the Web App
You may use plain HTML/CSS/JS or possibly a frontend framework. Here’s a simple example using plain HTML:
html
Копировать
Редактировать
copyright src="//telegram.org/js/telegram-web-app.js">
Hello from Telegram Mini App!
copyright>
const tg = window.Telegram.WebApp;
tg.expand(); // Makes the app take full screen
function sendData()
tg.sendData("Hello Telegram!");
Host this file using any static hosting provider.
⚙️ Step 3: Set Up Web App in Bot
Go to BotFather.
Use /setdomain to join up to your web app domain.
Use /setcommands to include a command like /start or /open.
In your bot code, you’ll send a keyboard button using a web_app object:
Example in Node.js (using node-telegram-bot-api):
js
Копировать
Редактировать
const TelegramBot = require('node-telegram-bot-api');
const token = 'YOUR_BOT_TOKEN';
const bot = new TelegramBot(token, polling: true );
bot.onText(//start/, (msg) =>
bot.sendMessage(msg.chat.id, "Open the mini app:",
reply_markup:
keyboard: [[ text: "Open App", web_app: url: "//yourdomain.com/app" ]],
resize_keyboard: true,
one_time_keyboard: true,
);
);
✅ Optional: Get User Data
In your frontend, will come your way Telegram user info via Telegram.WebApp.initDataUnsafe.
js
Копировать
Редактировать
console.log(Telegram.WebApp.initDataUnsafe.user);
Make certain to validate this data on your backend using Telegram’s Web App Authorization.
???? Bonus: Accept Payments
Telegram Mini Apps support payments via Telegram’s payment system.
Set up a payment provider via BotFather (/setpaymentoptions).
Use the Bot API’s sendInvoice approach to create payment flows.
Payments are processed securely via Telegram with support for services like Stripe.
???? Testing Your Mini App
Use Telegram on mobile or desktop (not the internet app).
Make sure your domain uses Hyper Text Transfer Protocol Secure.
Ensure your bot has access to web app features and commands.
???? Use Cases
Telegram Mini Apps can be used:
E-commerce (stores, carts, checkouts)
Booking and reservations
Games and entertainment
Form submissions
Personal dashboards
Telegram Mini Apps bridge the gap between messaging and fully interactive applications. By combining the reach of Telegram bots with the flexibility of web technologies, developers can build powerful experiences within the chat interface. Report this page
