[ENGLISH] Web development is one of the most in-demand programming jobs in the market nowadays, with companies worldwide struggling to hire and retain talents. This trend is reflected on a waging increase and ferocious competition for the best web developers available. In this course I propose a full-stack (front-end and back-end) approach to web development to tackle the current job market needs, as well to create your own websites and applications. For a beginner student we'll start with the internet foundations (what is the internet, HTTP requests, client/server communication) followed by an introduction to the most basic web development tools, namely HTML and CSS. We'll see what is JavaScript, its foundations and how to use it to enrich web pages. Once we're ready we'll take a step forward with React, an open-source, highly demanded front-end framework created by Facebook, and we'll dive deep into its concepts and tools. We'll also learn back-end development from scratch with Node and its main library, Express, along with essential concepts like request-response cycles, server availability, CORS and cookies. A database implementation in MongoDB will be introduced together with the Mongoose library for Node. Finally, we'll also see good development practices like code quality, programming with Visual Studio Code, command prompt interaction, creation of Git repositories and code versioning. At the end you must be able to build an on-line portfolio and succeed in modern web development tasks.
