WeSpark Backend API (Node.js + Express)

Overview

The WeSpark Backend is a Node.js and Express.js RESTful API that serves as the data and business logic layer for the WeSpark platform. It receives, validates, and persists feedback and opportunity data submitted by clients (mobile and web), and exposes endpoints for data retrieval and analysis. The backend is designed for scalability, maintainability, and easy integration with both local and cloud-based storage solutions.

Features

RESTful API for feedback and opportunity data
Data persistence using a local JSON file (with cloud-ready architecture)
Input validation and error handling
CORS support for cross-origin requests
Modular, extensible codebase

Technologies Used

Node.js (v20.19.2)
Express.js (v5.1.0)
JavaScript (ES6+)
npm (v10.8.2)
File System (fs) for local JSON storage
CORS middleware

Setup & Usage

Prerequisites

Node.js (v18.x recommended)
npm (v9.x recommended)

Installation

cd backend
npm install

Running the Server

npm start

The API will be available at http://192.168.0.152:3000 by default.

API Endpoints

Note: The following are example endpoints. Please refer to the source code for the latest details.

GET /feedback — Retrieve all feedback entries
POST /feedback — Submit new feedback (JSON body required)
GET /health — Health check endpoint

Configuration

Port: Default is 3000. You can override by setting the PORT environment variable.
Data File: Feedback is stored in feedback.json in the project root.

Development

Code is located in src/server.js.
Use modern JavaScript (ES6+).
Linting and formatting are recommended for contributions.

Deployment & Cloud Readiness

The backend is designed for easy migration to cloud platforms (e.g., AWS Lambda, Elastic Beanstalk, EC2).
For production, consider replacing the local JSON file with a managed database (e.g., DynamoDB, RDS).
Environment variables should be used for secrets and configuration in production.

Testing

Manual testing can be performed using tools like Postman or curl.
Automated tests can be added in a test/ directory (not included by default).
