React + Node.js + Express app

In this app you can build a working calculator from base elements in whatever order you like with help of Drag&Drops mechanism

Link to a deployed app: https://calc-constructor.herokuapp.com

There is 2 modes:

Mode	Functionality
Constructor	User can make use of Drag&Drop benefits in ordering components
Preview	User is able to make calculations with built calculator

Functionality:

1. Drag blocks from sidebar to canvas

4. Switch to other mode whenever you want

Techologies:

• Frontend: Typescript, React + React, Material-UI, Eslint.
