Backend Architecture

ConnieRTC's backend is built on Twilio Serverless Functions for scalable, secure API operations.

Technology Stack​

  • Twilio Serverless - Serverless function platform
  • Node.js - JavaScript runtime
  • Twilio API - Communication platform APIs
  • Database Connectors - Multi-database support

Directory Structure​

serverless-functions/
├── src/
│   ├── functions/
│   │   ├── common/           # Shared utilities
│   │   └── features/         # Feature-specific functions
│   ├── assets/               # Static files
│   └── utils/                # Helper functions
├── .env                      # Environment variables
└── package.json

Feature Functions Pattern​

Each feature's serverless functions follow:

features/
└── [feature-name]/
    ├── studio/               # Studio Flow webhooks
    ├── flex/                 # Flex API endpoints
    └── common/               # Shared feature functions

Development​

Running Locally​

cd serverless-functions
npm install
npm start

Environment Configuration​

Required environment variables in .env:

ACCOUNT_SID=AC...
AUTH_TOKEN=...
TWILIO_FLEX_WORKSPACE_SID=WS...

Function Types​

Protected Functions​

Require Twilio signature validation:

// filename.protected.js
exports.handler = async function(context, event, callback) {
  // Only accessible via Twilio webhooks
};

Public Functions​

Accessible without authentication:

// filename.js
exports.handler = async function(context, event, callback) {
  // Accessible to any client
};

Deployment​

# Deploy to Twilio
npm run deploy

# Deploy specific environment
./deploy.sh [account-name]
