NodeJS Training Course and Workshop in Bangalore, Mysore, Chennai, Hyderabad, Pune, Mumbai, Delhi, Noida, Gurgaon, Kolkata

NodeJS is a server-side JavaScript platform using an event-driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. This NodeJS training course provides a solid foundation in the latest skills and techniques for mastering and leveraging using Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application. You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this course you will learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well-known tools to beef up security of Express 4.16 applications.

By attending NodeJS workshop, delegates will learn:

Server-side JavaScript coding through the most up-to-date course on Node.js
Explore the latest JavaScript features, and EcmaScript modules
Walk through different stages of developing robust applications using Node.js

The NodeJS class is ideal for:

Experienced software developers seeking to enhance and extend their core web development skillset leveraging NodeJS. You should have practical experience developing basic software applications.
