Recently, I wrote a post called Zero to Express on OpenShift in Three Commands, which shows how to get started using Node.js, Express, and OpenShift together as fast as possible using the Node.js s2i (source-to-image) images that were recently released as part of Red Hat OpenShift Application Runtimes (RHOAR).
This post will add to the last one and show how we can start to debug and inspect our running code using the Chrome Developer Tools (DevTools) inspector.

Today Red Hat is making Node.js generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR). RHOAR provides application developers with a variety of application runtimes running on the OpenShift Container Platform.

This guide is designed to help you integrate your Red Hat Single Sign-On server with the OpenAPI (OAI)-based ActiveDocs in your 3scale developer portal. Although it has only been implemented with this particular Identity & Access Management solution (IAM), you could in theory make some customizations where necessary to integrate with another OpenID Connect-based solution.

Over the past few weeks I have been learning and enhancing my skills around the new buzz word “serverless” and trying to understand what this buzz is all about. As an ardent open-source developer, I was looking for a platform where I can develop and deploy the serverless functions, which is when I stumbled upon Apache OpenWhisk.
In this blog I will demonstrate how to build a simple nodejs function that can do reverse geocoding using Google Maps API, and how to deploy the functions on to Apache OpenWhisk.

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.

During the fall of 2017, we conducted a microservices survey with our Red Hat Middleware and Red Hat OpenShift customers. Here are eight interesting trends discerned by the results:
I. Microservices are being used to re-architect existing applications as much as for brand new projects
There seems to be a strong emphasis in the market by technology vendors for positioning microservices as being only for new projects. However, our survey reveals that organizations are also using microservices to re-architect existing and legacy applications.
Sixty-seven percent of Red Hat Middleware customers and 79 percent of Red Hat OpenShift customers indicated this. This data tells us that microservices offer value to users all along their IT transformation journey — whether they are just looking to update their current application portfolio or are gearing up new initiatives. So, if you are only focused on greenfield projects for microservices, it may be a good idea to also start evaluating your existing applications for a microservice re-architecture analysis. Microservices introduce a set of benefits that our customers have already started seeing, and they are applying these benefits not just to new projects but to existing ones as well.
II. Customers prefer a multi-runtime/multi-technology/multi-framework approach for microservices

In this blog entry, I want to introduce a “different” way to work with OpenShift. In the typical way to deploy a Pod to OpenShift, we have available a set of very useful objects we have build/image configurations. This takes the pain from us by hiding the details about image construction but, sometimes we just want to see some code running in the cloud. Or we want to see if our service/application is able to interact with nearby services or we have some code but we don’t want to use a git repo just yet. To solve that problem, I will show the concept of InitContainers, and how by being a little bit creative we achieve some cool stuff like deploying our code inside a running container.

In the past year, our team has re-written one of our internal apps from Angular to React. While earlier React experience on the team ranged from new to experienced, we learned a lot along this journey. Much of what we learned has been from experiencing pain points in development, or inefficiencies, and either researching others’ best practices or experimenting with what works best for us.
