Course includes all necessary information about Node.JS: NPM package manager, Express framework (routing, Pug template engine, middleware), REST approach, working asynchronously with NodeJS API, working with the file system, basic concepts of MongoDb and how to use it from Node.JS application. Also it covers advanced topics like NodeJS event loop, timers, event emitters, using Node streams, using Kafka for message exchange, WebSocket protocol, deploying and monitoring Node application in the cluster mode.
Throughout the course participants will build a real life web application with REST API which stores data in session, files and MongoDb database (frontend UI is provided). Course includes step by step solutions of the tasks, as well as additional tasks to gain the practical experience.
Course is suitable for web developers (React/Angular/Vue) and backend developers. Basic knowledge of JavaScript is required.
After completing the course, a certificate
is issued on the Luxoft Training form


Course aims to introduce listeners to NodeJS platform and features and to demonstrate how these features can be used in practice.
