Introduction

Role-Based Access Control (RBAC) is a security model that grants permissions to different types of users based on their roles. RBAC is essential in managing user access to a secure system and ensuring that only authorized users can perform certain actions. In this tutorial, we will demonstrate how to implement RBAC using Node.js, TypeScript, Express, REST API, JWT, and bcrypt for authentication.

We will be creating a REST API for an education management system with three types of users: admin, teacher, and student. Each type of user has specific permissions and actions that they are allowed to perform.

Prerequisites

Before we start, you should have a basic understanding of Node.js, TypeScript, and Express. You should also have Node.js installed on your system.

Setting up the Project

First, let’s create a new project and install the required dependencies.

mkdir rbac-tutorial
cd rbac-tutorial
npm init -y
npm install express bcrypt jsonwebtoken
npm install -D typescript ts-node ts-node-dev @types/express @types/jsonwebtoken
