Getting started

The Node.js backend for the mobile application is designed with a specific goal in mind: to assist individuals who are unable to speak. By integrating a powerful Machine Learning Library, the backend enables the conversion of handwritten text into speech, providing a means for users to save their daily conversations in the form of phrases.

One of the key aspects of this backend is its robust authentication system. The server implements authentication through email OTP (One-Time Password) and JSON Web Tokens (JWT). When a user registers or logs in, an OTP is sent to their email for verification. Once verified, a JWT is issued, which serves as a secure token for subsequent authenticated requests. This two-step authentication process ensures the privacy and security of user data.

Application Structure

• app.js - The entry point to our application. This file defines our express server and connects it to MongoDB using mongoose. It also requires the routes and models we'll be using in the application.
• routes/ - This folder contains the route definitions for our API.
• models/ - This folder contains the schema definitions for our Mongoose models.
• middleware/ - This folder contains the middlewares for our application.
• util/ - This folder contains the utility functions for our application.
• configs/ - This folder contains the configs for database connectivity.
