Description

This 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 the Node.JS application. 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). The course includes step-by-step solutions of the tasks and additional tasks to gain practical experience. This program 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
