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.

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...

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...

Introduction 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. Use Typescript One of the best decisions we ever made in our project was...

In this post, I take a look at the benefits TypeScript offers and demonstrate...

I returned late Sunday night from a trip to the south of France, where I was privileged to speak about Microservices, OpenShift, and how to do it all on Node.js.

This was a two-day conference, sponsored in part by Red Hat. It was great to see so many Red Hatters there and...

A while ago, I wrote a fairly long post attempting to shed some light on a few things you can do in your JavaScript classes to enforce the concept of data encapsulation - or data "hiding". But as soon as I posted it, I got some flak from a friend who is a Clojure programmer. His first comment about the article was this. Mutability and data encapsulation are fundamentally at odds. Eventually, he walked that back - but only just...

Several organizations are wondering (and sometimes struggling on) how to port their current workloads to cloud environments. One of the main characteristics of a cloud environment is that the infrastructure is provisioned dynamically. This implies, for example, that we don’t know a priori where our resources are being allocated (we can find that out, though). VMs or containers will receive a dynamic IP. Storage will be allocated somewhere and attached to our VMs or containers and so on. So, how...

NPM 4 was released recently, about 2 weeks ago, and with it came some major changes. Some breaking, some not, but there is an interesting deprecation that happened with regards to the prepublish script. Currently, if you had a prepublish entry in your package.json: { scripts: { prepublish: "nsp check" } } This would be run whenever you performed a npm publish. Which is probably what you would expect with a name like prepublish. Another thing was also happening though...

Node.js 7.0.0 was released just last week, and the announcement dropped a bombshell. I'm guessing the following announcement might freak some people out: DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. While the UnhandledPromiseRejectionWarning has been in node since 6.6.0, this deprecation warning is new --- basically, it means you've rejected a promise in your code, but you are not handling it, and...
