Technologies Used

The Backend process of React Native Food Delivery Backend are built using the core components of Node, Express, MongoDB, Passport JS. React Native Food Delivery Backend has also been constantly incorporating various other latest technologies.

MongoDB is a document-oriented database designed with both scalability and developer agility in mind. MongoDB's ability to store JavaScript objects natively saves time and processing power. Rather than storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with dynamic schemas. Instead of a domain-specific language like SQL, MongoDB utilizes a simple JavaScript interface for querying. Looking up a document is as simple as passing a JavaScript object that partially describes the search target .

  • NODE JS:

Node JS is a packaged compilation of Google’s V8 JavaScript engine, the libuv platform abstraction layer, and a core library, which is itself primarily written in JavaScript. Node JS shines in real-time web applications employing push technology over web sockets. The main principle of Node JS: use non-blocking, event-driven I/O to remain lightweight and efficient in the face of data-intensive real-time applications that run across distributed devices. It replaces the traditional request-response paradigm with a fast, two-way communication model. It is asynchronous without the use of threads, it is not memory-intensive. Node JS web sockets run on TCP, not HTTP, so low-overhead client-server communication is enabled in both directionS .

Ideally, if you are writing a mobile app, you want to cover all the bases – iOS, Android, and Windows – in order to obtain maximum market share or to grant your mobile workforce flexibility in device choice. A straightforward way to accomplish that is to write all the app’s logic in Node JS and place it on the backend. The user interface then runs on the mobile device under another language.

  • Express JS:

Express JS is server-side and mobile application framework, written in JavaScript. It builds single-page, multi-page, and hybrid mobile and web apps; Common back-end functions for web applications; APIs.

Express JS is a prebuilt Node JS framework that can help you in creating server-side web applications faster and smarter. Simplicity, minimalism, flexibility, scalability are some of its characteristics and since it is made in Node JS itself, it inherited its performance as well.

In short, Express JS did for Node JS what Bootstrap did for HTML/CSS and responsive web design. It made coding in Node JS a piece of cake and gave programmers some additional features to extend their server-side coding. Express JS is hands down the most famous Node JS framework - so much so that when most people talk about Node JS they surely mean Node JS + Express JS.

  • Passport JS

Passport is an authentication middleware for Node JS. Extremely flexible and modular, Passport can be unobtrusively dropped in to any Express-based application. Passport recognizes that each application has unique authentication requirements. Authentication mechanisms, known as strategies, are packaged as individual modules. Applications can choose which strategies to employ, without creating unnecessary dependencies.

  • SocketIO

Socket.IO is an event-based bi-directional communication layer for realtime web applications. It abstracts many transports, including AJAX long-polling and WebSockets, into a single API. It allows developers to send and receive data without worrying about cross-browser compatibility. Socket.IO provides both server-side and client-side components with similar APIs.

  • On the server-side, Socket.IO works by adding event listeners to an instance of http.Server .
  • The HTTP server will begin to serve the client library at /socket.io/socket.io.js

Since both the server and client's Socket object act as EventEmitters you can emit and listen for events in a bi-directional manner.

Mobile App

Technologies Used

The components of the App are built using the core components of React Native. The theme also constantly incorporates various other latest technologies.

React Native

React Native helps in making the development work easier and allowing the developers to focus on the core app features in every new release. It is the fastest-developing mobile app development that essentially permits you to create an isolated product with often outcomes. The hymn of React Native — learn once, write anywhere. React Native takes charge of the view controllers and programatically generates native views using javascript. This means that you can have all the speed and power of a native application, with the ease of development that comes with React.

React Navigation

React Navigation provides 100% native platform navigation on both iOS and Android for React Native apps. The JavaScript API is simple and cross-platform - just install it in your app and give your users the native feel they deserve.

WebDashboard

Technologies Used

The components of the App are built using the core components of React. The theme also constantly incorporates various other latest technologies.

React

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called components. We’ll get to the funny XML-like tags soon. We use components to tell React what we want to see on the screen. When our data changes, React will efficiently update and re-render our components.

React Bootstrap

React-Bootstrap replaces the Bootstrap JavaScript. Each component has been built from scratch as a true React component, without unneeded dependencies like jQuery.As one of the oldest React libraries, React-Bootstrap has evolved and grown alongside React, making it an excellent choice as your UI foundation.

React router

A tool that allows you to handle routes in a web app, using dynamic routing. Dynamic routing takes place as the app is rendering on your machine, unlike the old routing architecture where the routing is handled in a configuration outside of a running app. React router implements a component-based approach to routing. It provides different routing components according to the needs of the application and platform.
