Hello , Welcome To The Course MERN Stack Retail Store POS Application.

First of all....

What is POS ?

A point of sale (POS) is a place where a customer executes the payment for goods or services and where sales taxes may become payable. A POS transaction may occur in person or online, with receipts generated either in print or electronically.

So in this course we will teach you how to build a POS application using React , Redux , Node , Node , Mongo.

It is almost similar to an ecommerce application but here we don't have any user dashboards or user screens. We will have everything related to the Stores / Malls / Hotels etc.

We will cover the following features / concepts in this MERN Stack POS Application.

React / UI

• What is POS

• Difference Between POS / Ecommerce Application

• React topics like routing , states , props , components , storage etc.

• Redux for State Management

• We will make all the API calls without redux only , We just use redux for cart functionality , So you need not to be a pro in Redux.

• For Building UI we will use the Ant Design Library. It is the world most second popular UI framework for React.

• For normal styling we will use bootstrap classes to speedup our development process.

• One of the best part about the UI in this application is you can also generate / print a bill with the items and amount for a customer.

Node / Express / Mongo

Working with node with the combination of express and mongo DB.

Making complex schemas , models in Mongo DB.

Creating Rest Full API's .

Deploying the app to heroku

MERN Stack: MERN Stack is a JavaScript Stack that is used for easier and faster deployment of full-stack web applications. MERN Stack comprises of 4 technologies namely: MongoDB, Express, React and Node.js. It is designed to make the development process smoother and easier.

Each of these 4 powerful technologies provides an end-to-end framework for the developers to work in and each of these technologies play a big part in the development of web applications.

Pre Requisites

-------------------------------------------------------------------------------

React

React is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It is maintained by Meta and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications

Redux

Redux is an open-source JavaScript library for managing and centralizing application state. It is most commonly used with libraries such as React or Angular for building user interfaces. Similar to Facebook's Flux architecture, it was created by Dan Abramov and Andrew Clark.

Node

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser.

Express

Express.js, or simply Express, is a back end web application framework for Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. It has been called the de facto standard server framework for Node.js.

Mongo DB

MongoDB is a source-available cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License.
