Développement Web - Node JS

Web Development - Node JS

Web development with Node.js involves creating web applications using Node.js, a server-side JavaScript execution platform. Node.js allows developers to use JavaScript on both the client and server side, making it simpler to create applications real-time web, servers API and other dynamic web solutions. Thanks to its speed and scalability, Node.js is widely used for developing websites and interactive web applications, especially in the technology and Internet of Things fields.

Node js training objectives

Operational objective :

Know how to develop server applications in JavaScript with Node.js.

Educational objectives :

At the end of Node.js training, you will have acquired the knowledge and skills necessary to:

Know how the Node.js platform works and common uses
Know the specifics of server-side programming in JavaScript
Know how to install and configure a Node.js server
Know the particularities of asynchronous programming and those of event-driven programming
Know how to configure and manipulate the Node.js API and its REST API server
Know how to connect to a database
Implement Node.js best practices

Who is this training for?

Audience :

This Node.js training is mainly aimed at developers or architects who need to use the JavaScript language on the server side with Node.js, in particular as part of a Vue.js project. The developers or architects involved are intended to design highly concurrent event-driven network applications that can scale up. They can also be called upon to design multiplatform applications involving frameworks such as Ionic or Electron, to design web servers or even Rest APIs.

Prerequisites:

Participants must have a good overall knowledge of the JavaScript language validated in one or more prior development projects. A first approach to a JavaScript framework would be ideal, especially on the client side.

A pedagogy based on practice

Acquire essential skills by validating professional projects.
Progress with the help of a professional expert.
Gain real know-how as well as a portfolio to demonstrate it.
