Overview

The MERN Multitenancy is a software framework that utilizes a multi-layered architecture for building scalable web applications. It is built on the MERN stack (MongoDB, Express, React, Node.js) and supports multitenancy, allowing multiple tenants (users or organizations) to use the application simultaneously with their own isolated data.

Features

Multi-layered architecture: The application follows a structured architecture with layers including app, router, controller, and service, making it easy to manage and develop.
TypeScript: The back-end of the application is written in TypeScript, providing type checking and enhancing code quality.
Subdomain-based tenant resolution: Tenants are resolved based on the subdomain of the requested URL, ensuring isolation and security.
MongoDB with per-tenant collections: Each tenant has its own collection in the MongoDB database, providing data segregation and efficiency.
JWT authentication: JSON Web Tokens (JWT) are used for authentication, ensuring secure communication between the client and server.
CORS and domain whitelisting: Cross-Origin Resource Sharing (CORS) is implemented with a whitelist of allowed domains, enhancing security.
Password hashing with salt and pepper: User passwords are securely hashed using a combination of salt and pepper techniques for added protection.
User and tenant data binding: User and tenant identifiers (userId and tenantId) are bound to the Request object, simplifying data retrieval and manipulation.

Summary

The MERN Multitenancy framework provides a robust solution for building scalable web applications with multitenancy support. With its multi-layered architecture, TypeScript-powered back-end, subdomain-based tenant resolution, and MongoDB's per-tenant collections, it offers a secure and efficient way to handle multiple tenants. The use of JWT authentication, CORS with domain whitelisting, and password hashing with salt and pepper further enhance security. Overall, this framework simplifies the development and management of multitenant web applications.
