Deploying a Telegram Bot Using Google Cloud Functions

This project involves deploying a Telegram bot on Google Cloud Functions, enabling serverless operations. Google Cloud Functions allows you to run code without provisioning or managing servers, making it a cost-effective and scalable solution for deploying bots. The project covers setting up the Cloud Function, integrating with the Telegram API, and configuring the necessary permissions and triggers. This demonstrates skills in serverless architecture, event-driven programming, and cloud services orchestration.

Technologies: Node.js Google Cloud Functions Telegram API

Instructions

Step 1: Create a Telegram Bot

Use the BotFather on Telegram to create a new bot. Note down the bot token provided, as it will be used to authenticate requests.

Step 2: Set Up Google Cloud Function

In the Google Cloud Console, create a new Cloud Function. Choose Node.js as the runtime and set up the service account with the necessary permissions. Alternatively, you can use Infrastructure as Code (IaC) tools like Terraform or Deployment Manager.

Step 3: Write Cloud Function Code

Write the code for the Cloud Function to handle messages from Telegram. Use the Telegram bot token for authentication and integrate with the Telegram API.

Step 4: Configure HTTP Trigger

Set up an HTTP trigger for the Cloud Function to be invoked by the Telegram bot. Configure the endpoint URL that will be used as a webhook.

Step 5: Deploy the Cloud Function

Deploy the Cloud Function and note down the trigger URL for the next steps.

Step 6: Set Webhook in Telegram

Set up the webhook in Telegram to forward updates to the Cloud Function's trigger URL using the Telegram Bot API.

Step 7: Test the Telegram Bot

Test the Telegram bot by sending messages and verifying the responses. Debug and troubleshoot as needed.
