This article will focus on debugging JavaScript code within Microsoft Edge Developer Tools. The Edge DevTools are a powerful toolset built into the Edge browser on Microsoft Windows 10. The DevTools are also available as a standalone app to download from the Microsoft Store, if one prefers to run them separately from Edge itself. We’ll be using Raygun Crash Reporting to find the stack trace and the line of code the error occurred on. You can sign up for a free 14-day trial here.

A majority of front-end developers deal with this buzzword all the time: V8. A big part of its popularity is due to the fact that it led JavaScript to a new level of performance. Yes, V8 is very fast. But, how does it perform its magic and why is it so responsive? The official docs state that “V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and Node.js, among others”.

Boom! Our latest release of the AppSignal for Node.js package now includes support for Next.js. The Next.js integration also includes end-to-end insights into application performance, as well as error tracking.

A good application monitoring solution will provide you with the visual representation of the performance, growth, and usage of your AJAX applications. These metrics, along with others, are the critical metrics that need to be checked to ensure no interruptions occurs. Monitoring your applications ensures that your application is delivering you the results it was actually designed for. Below are the few reasons to have your application monitored.

In today’s post, we’re going to demystify how the number of JavaScript dependencies grows while we’re working on a relatively simple project. Should you be worried about the number of dependencies? Keep in mind that this blog post is related to the Ride Down The JavaScript Dependency Hell blog post that was released a while back. We’ll show a “real-world” example of how a project’s dependencies can grow from zero to 13K.

In this guide, we’ll cover how you can use Morgan npm to log requests and other aspects of your web application built on Express (or any of the similarly architected frameworks around). So what can Morgan do for you? And when would you need it? As you’ll see in a second if you’re working with Express or a similar framework (such as restify) you’ll have the need to log incoming information about the requests, this framework was designed specifically for that, just keep reading.

ReactJS combines the speed of JavaScript with unique rendering capabilities to make applications that are highly dynamic, performance oriented, and responsive to user input. State of JS report 2018 cites performance as the major reason ReactJS has gained so much popularity in such a short time. When it comes to options for building single-page applications (SPAs), React delivers performance advantages over Angular and other JavaScript frameworks and libraries.

The digital era always strives for newer and more innovative technology that can make the world a better place. The modifications that we are observing in current technology are not just rapid, but exponential.

Web applications like knockout.js help you to reach out to your audience and customers. And as your customer base increases, your web-application evolves so that you can cater to their varying needs. But the more features you introduce in your application, the more requests and responses need to be handled by your applications. That, coupled with design (CSS) can make your web applications pretty bulky. You must be thinking, “So what!
