In recent years, JavaScript has evolved into a very strong and interesting programming language to work on and its market share has soared to new heights, particularly after ES6 was released in June 2015, making it the most popular programming language in the web development space.

Consumers and business users have grown to demand extremely responsive and smooth online experiences regardless of the device they're using, thanks to the rapid expansion of mobile. Here comes JavaScript to the rescue!

To begin with, it has been widely accepted by the organizations and teams that are embracing JavaScript's support on many levels in their stack, including front-end, back-end, embedded devices, hybrid apps, and much more, as it becomes more popular.

Today, practically every website employs JavaScript, making it an extremely useful language to master. If projects are becoming increasingly reliant on JavaScript, developers must make use of all the language and ecosystem have to offer, as well as have a better grasp of the internals, in order to create exceptional products. You will be able to develop better, non-blocking apps that use the given APIs effectively if you know the details.

As it turns out, a large number of developers use JavaScript on a daily basis but are unaware of what happens behind the scenes. For newcomers and even experts in the industry, JavaScript is quite complex and perplexing. It's difficult to master because of the dynamically typed nature, as well as the numerous inconsistencies.

Any competent JS course or book will not suffice to conquer the JS track, as new frameworks emerge on a regular basis. Rather, To become a JS Master, the most efficient strategy is to learn by doing.

But how do you pick relevant projects?

Many people just begin with a TODO app and believe they are ready for production-grade JS programming. To address this issue, Let me introduce you to the Crio Projects Hub.

Authentication in Node.js for a web app

Access control is the foundation of all security. The right individuals should be admitted, while the bad guys should be kept out. This is achieved by validating – or authenticating – the identity of the individual seeking access and then determining whether or not the person is permitted to enter.

Why is this trivial task challenging?

Because the web's application protocols, HTTP and HTTPS, are stateless, rigorous authentication would necessitate end-users re-authenticating each time they accessed a site through HTTPS. Rather than burdening end users with that effort for each online interaction, protected systems rely extensively on token-based authentication, which requires authentication just once at the start of a session. The authenticating system sends a signed authentication token to the end-user application, which is attached to each client request.

This whole process will be demonstrated in this project and you will get a good hold on the topic of authentication as a service.

Skills to gain from this project

You will be developing an end-to-end application that shows how to establish authentication in an application using Node.js, JWT, and other best practices. A brief list of tech used in this project is as follows:  

  • Node.js:  The Nodejs runtime is based on Chrome's V8 JavaScript engine.Node.js is lightweight and efficient because it employs an event-driven, non-blocking I/O architecture.
  • Asynchronous Programming: to allow programs to perform many tasks at once.
  • Postman: an API Development Collaboration Platform.
  • Express.js: back end web application framework for Node.js designed for building web applications and APIs.
  • JWT:  an open standard that specifies a compact and self-contained method for securely sending information as a JSON object between parties.

You will learn about several authentication mechanisms. Implement them, analyze and identify their flaws, and then consider how to enhance them. You may utilize this expertise in almost any real-world application and decode the authentication techniques employed by the most popular apps.

Who should try this project

Prerequisites

This project will need a basic understanding of JavaScript, HTTP, and Nodejs fundamentals.
