A warm welcome to the Node.js course by Uplatz.

Node.js is a JavaScript environment that allows you to perform a multitude of tasks and build all sorts of exciting applications.

Node.js can be defined as a dynamic, cross-platform and open-source JavaScript framework or runtime environment that is built on the Google Chrome JavaScript V8 engine. Developed by Ryan Dahl in 2009, Node.js was initially implemented as a client-side scripting language. Nowadays, it is used to execute JavaScript code and scripts that run server-side to create dynamic web pages.

Node.js is an open source server environment and essentially allows you to run JavaScript on the server. In summary, Node.js is an open-source, cross-platform, JavaScript runtime environment that provides way to run JavaScript code outside of a web browser. Node.js helps us to use JavaScript for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser.

Node.js Features and Benefits

Most web developers implement Node.js due to its amazing and powerful features. Key features of Node.js include:

• Faster code execution

• Highly scalable

• Non-blocking APIs

• No buffering

  
  

With such wonderful features, Node.js is widely used for creating server-side and networking applications. The following are the key areas where Node.js is widely used:

• I/O-bound applications

• Data streaming applications

• Data-intensive real-time applications (DIRT)

• JSON API-based applications

• Single-page applications

Most of the top organizations use Node.js for e.g. IBM, Apple, AT&T, and the like.

Uplatz provides this comprehensive training on Node.js. This Node.js course provides an introduction to web application development by way of JavaScript and the node.js environment. The delegates will learn the basics of server-side web development using the MEAN stack (MongoDB, Express.js, Angular/Angular 2, node.js). The Node.js course introduces students to models of software development that can apply to any web development environment, including the application server (node.js), Model View Controller (MVC) frameworks using Express.js, front-end frameworks (Angular), and databases (MongoDB). The course includes setting up a node.js environment, building web APIs and full-stack JavaScript applications, and following good application development practices.

This Node.js training also teaches you to build a production-ready Node.js JSON API. The course uses MongoDB for the database to help you gain hands-on experience in developing the backend in Node.js.
