Twilio Onboarding Project

Project Introduction

This project is a Node.js web application utilizing Twilio APIs to demonstrate communication capabilities such as sending messages and making calls. It's designed to help developers understand and implement Twilio-based solutions in their applications.

Prerequisites

Before you can run this project, you need the following installed:

Node.js (v14 or higher)
npm (v6 or higher)
A Twilio account with appropriate API keys

Setup Instructions

Clone the repository to your local machine:

git clone [repository-url]
cd twilio-onboarding

Install the required dependencies:
```
cd app
npm install
```
Configure your environment variables:
- Copy sample.env to .env:
```
cp sample.env .env
```
- Fill in the necessary details in .env based on your Twilio account settings.

Running the Development Server

To start the development server, run the following command in the app directory:

npm start

This will launch the server on localhost with the default configured port (usually 3000), allowing you to access the application through your web browser.

File Structure

File/Directory	Description
`index.js`	Main entry point for the application. Initializes the server and imports routes.
`routes.js`	Contains routing logic for the application. Defines endpoints and associated handlers.
`endpoint-methods/`	Directory containing specific methods for handling requests at different endpoints.
`twilio-helper/`	Helper functions and utilities for interacting with Twilio APIs.
`package.json`	Lists project dependencies and metadata.
`package-lock.json`	Locks down the versions of installed npm packages.
`.env` / `sample.env`	Environment configuration files. `.env` is for production, and `sample.env` serves as a template.
`node_modules/`	Contains npm packages installed for the project.

Detailed Code Explanation

`index.js`

This file serves as the entry point of the application. It sets up the Express server and imports all routes from routes.js. Here, you'll also find middleware configurations and the server's listen function.

`routes.js`

Handles the routing of the application. It imports various methods from endpoint-methods and assigns them to specific routes. This file is crucial for directing incoming requests to the correct handlers.

`endpoint-methods/`

This directory includes various JavaScript files, each corresponding to a different set of functionalities or API endpoint interactions. These methods are used by routes.js to handle specific tasks like sending SMS, making calls, etc.

`twilio-helper/`

Contains utility functions and configurations specifically tailored for Twilio API interaction. This includes initializing the Twilio client and creating functions that facilitate sending SMS or making calls.
