Create simple POS with React.js, Node.js, and MongoDB : Simple RBAC

In this chapter, we are going to continue from where we left off from the previous chapter intuitive with a plethora of functionalities.

Defenition: POS – “Point of Sale”. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer (which may be a cash register printout), and indicates the options for the customer to make payment.

In the previous chapters, we integrate the React table with the react-table package and added more dynamic features to it which made the Table. In this chapter, we are going to continue from where we left off from the previous chapter intuitive with a plethora of functionalities.

In this chapter, we are going to continue from where we left off from the previous chapter. We are going to work on Role-Based Access Control (RBAC) feature for our react app. We are going to have two roles for now: admin and employee.

  1. Admin can control everything in the app.
  2. Employees can only view specific screens and perform specific functions.

The implementation of the employee role is simple as we already have fields that specify user roles. We are going to use those user roles for conditional rendering with the react-rbac-guard package. This package solves our problem easily and makes things easier while conditional rendering. The sole purpose of this package is to manage the visibility of particular components depending on user credentials.

We are going to work on the frontend section of the project for this chatter.

So, let’s get started!

Installing RBAC package

First, we need to install the react-rbac package by running the following command in our project terminal:


yarn add  react- rbac- guard

Fortunately, they provide a demo as well which helps a lot to implement in our project.
