Скачать или смотреть DAY-19 Email Duplication Check + Dynamic Table CRUD in Sequelize | Node.js + TypeScript

Code: https://github.com/Sheikh-369/School-...

In today’s video, I walk you through implementing full CRUD operations using Sequelize with dynamic table names—a common but powerful technique when working with multi-tenant applications like school or business platforms. 🏫

You’ll also see how to handle email duplication checks during user registration using Sequelize’s findAll() method.

🔧 Technologies used:

Node.js

Express.js

Sequelize ORM

PostgreSQL/MySQL (any supported DB)

TypeScript

👨‍💻 Key Highlights:

Dynamic table structure for multi-school support

Secure and scalable query handling using replacements

Email existence validation during registration

Typed request structure using custom IExtendedRequest

Protected routes with middleware

This is part of my ongoing internship project (Training Platform SaaS) using the MERN Stack + TypeScript + Next.js.
