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...

As of its release 2.19, the Red Hat Mobile JavaScript Client SDK contains a TypeScript definition file. By providing type definitions our JavaScript SDK can easily be used in applications developed using TypeScript. As a developer with a few years of JavaScript experience, I was initially skeptical of TypeScript, but after using it for a short period, I'm not sure how I ever managed without it! 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. The conference was RivieraDev/JUDCon: Riviera 2017 and took place in Sophia Antipolis, near Nice, Cannes, St. Tropez and other fabulous Mediterranean cities on the southeastern coast of France. 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...

Eclipse Vert.x is a toolkit used to build reactive and distributed systems on the Java Virtual Machine. Vert.x supports a variety of languages letting you choose which one you’d prefer. The Vert.x Core cheat sheet covers the creation of a project using Apache Maven, Gradle or the Vert.x CLI, and references most common Vert.x Core APIs, in 3 different languages (Java, JavaScript, and Groovy). Forgot how to create an HTTP server, use the HTTP client, implement a request-response on the...

Red Hat Mobile Application Platform (RHMAP) lets teams extend their development capabilities to mobile by developing collaboratively, centralizing control of security and using back-end integration with a range of cloud deployments. We have just completed the deployment of the RHMAP v3.15 to all our actively updated grids. Please pay particular attention to notes on deprecations and upcoming removals. Full release notes including a list of known issues, customer-facing bug-fixes and changes are available on the Customer Portal here. Summary iOS...

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...

For a long time during my early career, I was an OO --- object oriented --- developer. I genuflected regularly in front of the altar of data encapsulation, object hierarchies and static typing. And the syntax. Oh the syntax! But I have changed, of course, and so much of the dogma and ceremony that I participated in during those times has come to seem a lot less important than it was 20 years ago. Languages, and developers evolve. But that...

For your end users, one of the most important aspects of your API is the perceived response time --- if your mobile application takes an excessive amount of time to load data, users will get frustrated. In this series of blog posts, we’ll cover three ways to approach building a RESTful API that leads to better user experience by minimizing perceived response time. These strategies include: processing requests quickly, reducing payload sizes, and eliminating requests entirely, or only downloading data...

Node.js is a JavaScript runtime built on top of Chrome's V8 JavaScript engine. It is highly event-driven, and leverages non-blocking I/O model that makes it lightweight, efficient, and incredibly productive to use. It's that last bit, "productive", that I want to focus on today. One of the things that i feel makes Node(and NPM) so great is the ease in which you can add and use third-party modules. As most node.js developers know, to start using an external module, you...

Last June, we announced the availability of version 4.0 of our product. This was the culmination of months of hard work and demonstrated our constantly expanding set of capabilities. I went on to recap the key technology choices made over five years ago, choices that proved to be visionary for our mobile platform’s architecture and functionality: Node.js and containers. We are very proud of our accomplishments with Red Hat Mobile Application Platform 4.0 and the new technologies we introduced to...

Last June, Eclipse IDE had a great release, named Neon. It features, among many other less visible but still quite useful improvements, many new functionalities for everyone. If you did not migrate yet and are still using an older Eclipse version, just move to Neon right now, it’s worth it! For this Neon release, Red Hat managed to increase its contributions to the Eclipse IDE. The 2 main teams doing Eclipse IDE development (to package Eclipse IDE as .rpm for...

Objective Some days ago, I was having an argument with a few Java developers about Node.js, they asked questions like “why should I use that?” or “what’s the benefit?”, I told them by memory that Node.js is an event driven I/O, and thanks to that you will end up writing very efficient server-side applications. They come back saying that they can get the same effect using threads. Thing is I wasn't fully prepared to explain the difference, I had a...
