Set Up Your Google Cloud Platform (GCP) Project

• Go to the Google Cloud Platform console (console.cloud.google.com).
• Create a new project or select an existing project.
• Navigate to the 'APIs & Services' -> 'Library' section.
• Enable the required APIs such as Compute Engine API.

Create and Configure a Virtual Machine (VM)

• Navigate to the 'Compute Engine' -> 'VM Instances' page within GCP.
• Click on 'Create Instance' to set up a new VM.
• Configure the VM based on your requirements (select machine type, region, etc.).
• Add necessary firewall rules to allow HTTP and HTTPS traffic if needed.
• Click 'Create' to finalize the setup of your VM instance.

Install Required Software on the VM

• SSH into your VM instance through the GCP console or use your preferred SSH client.
• Update your packages: sudo apt-get update
• Install necessary software, for example, Node.js if you are running a node application:
  sudo apt-get install nodejs
sudo apt-get install npm
• If using a different environment, install necessary software accordingly.

Deploy Your Bubble App

• Go to your Bubble application editor.
• Navigate to the 'Settings' -> 'API' section.
• Enable any necessary APIs (like backend workflows) and note down the endpoints you will be using.

Connect Bubble with the GCP VM

• In the backend of your application running on GCP VM, use HTTP requests to interact with Bubble's API.
• Example using Node.js:
  

  const axios = require('axios');
  axios.post('https://yourappname.bubbleapps.io/api/1.1/wf/endpoint\_name', {
    param1: 'value1',
    param2: 'value2',
  })
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error('Error:', error);
  });

• Ensure you replace yourappname and endpoint\_name with actual values from your Bubble app.

Secure the Communication

• Use HTTPS for secure communication between the VM and Bubble.
• On the GCP VM, install SSL/TLS certificates (use Let's Encrypt or any other certificate authority).
• Configure your server software (like Nginx or Apache) to use these certificates for secure HTTPS connections.

Testing and Monitoring

• Use the GCP console to monitor your VM's performance and logs.
• Utilize Bubble's built-in logs and debugging tools to monitor API request and response data.

Handling Errors and Debugging

• Ensure proper error handling is implemented in your backend code.
• Example in Node.js:
  

  axios.post('https://yourappname.bubbleapps.io/api/1.1/wf/endpoint\_name', {
    param1: 'value1',
    param2: 'value2',
  })
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    if (error.response) {
      console.error('Response error:', error.response.data);
    } else if (error.request) {
      console.error('Request error:', error.request);
    } else {
      console.error('Other error:', error.message);
    }
  });

Final Steps and Deployment

• After testing the entire setup locally, consider setting up CI/CD pipelines for continuous deployment.
• Ensure that your deployment scripts automatically install dependencies and set up the required environment on the VM.
