ECMAScript modules (ESM) are the official standard format for packaging JavaScript code for reuse.

Event Emitters are one of the most important built-in APIs since much of Node.js' core is built around an idiomatic asynchronous event-driven architecture. Event Emitters can help developers create a publisher-subscriber pattern with ease.

Look back at Red Hat's involvement at the OpenJS World 2021 conference. We took part in sessions exploring the impact of Node.js and JavaScript on technology.

JavaScript promises are one of the most useful features that the language offers us that help with handling asynchronous operations easily.

We show how Nodeshift can help abstract the complexity of a Red Hat OpenShift deployment.

Born of the browser wars of the 1990s, JavaScript has gone from a simple scripting language to be the most important ecosystem of the development world.

Get started with Node.js 12 on Red Hat OpenShift with these quick examples showing how to deploy an application using the Node.js 12 image.

This article, which is part 3 of a series about deploying modern web apps on Red Hat OpenShift, shows how to run your app's development server on OpenShift while syncing with your local file system.

How to generate or process CloudEvents using Vert.x. CloudEvents describe event data in a common, standardized way based on a spec from CNCF

Part 2 describes how to use the Node Builder image as a "pure" builder image and combine it—using an OpenShift chained build—with a pure web server such as NGINX for a more production-ready build.

This blog series shows how to deploy modern web apps, such as React and Angular apps on OpenShift using the fewest steps. Part 1 describes two commands for easily deploying web apps.

It can be complex to set up an end-to-end integration test infrastructure, but the process can be simplified by using an infrastructure-as-code approach. In addition, running integration tests for multiple OS/browser combinations can waste resources and time, but a container orchestrator and ephemeral workloads can help mitigate that. This article shows how to build behavior-driven development (BDD) container-native integration tests and run them in OpenShift to overcome these obstacles.

New releases: Red Hat Developer Studio 12 and Container Development Kit 3.5. Learn about the new features and updates to other developer tools for Windows, macOS, and Red Hat Enterprise Linux.

This post shows the minimal setup that is required to use the Chrome Developer Tools (DevTools) inspector to debug and inspect a Node.js application that is running on OpenShift.

The next online DevNation Live Tech Talk will be Thursday, April 19th at 12 p.m. EDT. The topic is "Enterprise Node.js on OpenShift" presented by Lance Ball.

With the recent announcement that Node.js is available as part of Red Hat OpenShift Application Runtimes, I wanted to see how easy it was to deploy an Express.js app on Red Hat OpenShift. It was quite easy to go from zero to having an Express app deployed and running. I show how using npx and nodeshift.

Today Red Hat is making Node.js generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR).

How to secure your API documentation with Red Hat Single Sign-On. This guide is to help you integrate your Red Hat Single Sign-On server with the OAI-based ActiveDocs in your 3scale Developer Portal. Although it has only been implemented with this particular IdP you could in theory make some customisation

In this blog we will see how to build a simple nodejs function that can do a reverse geocoding using GoogleMaps API.,and deploy the functions on to OpenWhisk

Use Private NPM modules with RHMAP. In this Blog post entry I will try to cover, how to use Red Hat Mobile Application Platform with private npm modules from registry.npmjs.org.
