NodeJS Programming

In the course NodeJS Programming participants learn how the NodeJS JavaScript library can be used on the server side of Web Applications.

Node.js Library

The Node.js library, the popularity of which is still increasing, it is also part of the MEAN stack (MongoDB, ECMAScript, Angular and Node) which is aimed at the development of high-speed I/O-centric applications.

Node en NPM

The course starts by discussing the architecture of the Node.js library with runtime modules as filesystem, events and process. Also the NPM package manager that allows community modules to be included is treated.

Asynchronous Event Handling

Next the asynchronous event handling model of NodeJS is on the course schedule and the use of promises and futures of ECMAScript 6 and 7 for the handling of callbacks is explained.

Streaming Data en Express.js

Also attention is paid to the processing of streaming data and File I/O in NodeJS. Also the handling of multiple concurrent client requests in NodeJS is discussed as well as the Express.js Framework that deals with templating, routing and middleware services.

Database Access

The Database Access module will show you how to integrate NodeJS capabilities in the backend with databases like MongoDB, MySQL and SQLite.

Rest API

Finally attention is paid to the creation of a Rest API and using AngularJS for Frontend.
