Node.js

I’ve tried to use the ngrok npm package in my application, but as the documentation says: “The ngrok and all tunnels will be killed when node process is done.” I need the process to “survive” my application. Let’s see what we can do about that…

I love SVG, but sometimes they are hard to create, especially when you need to visualize diagrams. HTML is way easier to program. So why not combine them? Can we use HTML to generate an SVG? And can we use JsFiddle to generate that HTML?

Slack is fully awesome. At Wehkamp we use it for our internal communication and as a tool for our DevOps. The Slack API allows us to build even more advanced integrations. In this blog I’ll explore how to use the API to create powerful progress indicators by updating a Slack message.

To give teams a jump start we’ve created the bot-zero open source project. It solves some setup and development problems. In this blog I’ll show how to get up and running in minutes and I’ll explain some of the choices we’ve made.

Lately we’ve been playing around with ChatOps at Wehkamp. We added a Hubot to our Slack channels to automate some operational jobs. It makes work more fun and way easier. As it is hosted in our own infrastructure, it can interact with our micro-services. In this article I explore how to use ES6 and a Promise to implement a call to a simple web-service.

TypeScript allows for better JavaScript development. JavaScript is getting useful in more domains. But different systems require different ways of handling modules and exposing features. TypeScript solves this by compiling differently when a target is specified.

But what if you need a TypeScript script that supports both vanilla browser JS and Node.js? What if you need to expose 10+ classes?

Recently I’ve been playing around with NPM. I switched my unit tests from QUnit to Mocha. This was not as straight forward as one would hope. In this blog I’ll show some example code. At the end I’ll link to a side by side comparison of the entire test project. Hopefully it helps you to convert your code. I’ll be using the Chai BDD assertion engine.

Node.js is getting more popular by the day. It breaks JavaScript free from the browser. I would love to auto start an application – much like a Windows service – without keeping a console window open. There are many services to wrap node applications into an executable, but I like to stick with just Node. This small trick will make your Node application windowless on Windows.
