Everyone seems to be making chat apps these days, but messaging apps are merely the tip of the iceberg. Consider this for a moment, within the real-time domain, there are a plethora of different things you can create. We'll start with some fundamental concepts and work our way up to see how to go real-time with Node and React in the following post. By the end of this article, you will have created a very simple real-time application. That will be a lengthy post!
Artillery is an open-source command-line tool purpose-built for load testing and smoke testing web applications. It is written in JavaScript and it supports testing HTTP, Socket.io, and WebSockets APIs. This article will get you started with load testing your Node.js APIs using Artillery. You’ll be able to detect and fix critical performance issues before you deploy code to production.
A bug on your Node.js application can mean many things: In other words, a bug on your Node.js application can mean a lot of different things depending on the industry you are working in. Some industries can't afford 5 minutes down; others can afford weeks down. Even more important, the software - correctly working - can impact lives.
Error handling is one section of our job that we tend to neglect, especially when working on something new, interesting, or something we just need to get working. We’ll handle errors later, we say — and that’s often a big lie. But that’s not even the worst part. The problem comes when we decide to ‘quickly’ add some code to handle our errors and completely forget about the importance and relevance of a properly constructed error message.
Errors happen in every application. Devs have to decide: do you write code to handle the error? Suppress it? Notify the user? Report it to the team? In this article, Ayo Isaiah walks us through every aspect of the JavaScript error system. He'll show us how to work with errors and discuss appropriate choices for real-world scenarios.
Node.js v17.0.0, the latest major version of the popular JavaScript runtime, has just been released. It supersedes v16 in the Current release line of the runtime. V16 is now in line to be promoted to the long-term support (LTS) channel on October 26, 2021, as it’s an even-numbered release. Despite being a relatively minor update, this release brings several refinements to the runtime, including more promisified APIs, JavaScript engine upgrades, and OpenSSL 3.0 support.
Docker is a software platform that enables packaging an application into containers. These containers represent isolated environments that provide everything necessary to run the application. Dockerizing an application refers to packaging it in a Docker image to run in one or more containers. Dockerizing an application involves specifying everything needed to run the application in a Dockerfile and then using the file to build a specialized Docker image that can be shared to multiple machines.
OAuth2 is everywhere. From "Login With Facebook" buttons to back-end API authentication. But how does it work? In this article, Diogo Souza will give us a gentle introduction to the big concepts behind OAuth2, then walk us through implementing it in Node.js.
