When working on the bot-zero-sharp project, we had the need to decouple the request handler and the creation of the chatbot. We like our request handlers to be automatically detected and added to our pipeline. In this article we’ll discuss how we use background services to create a chatbot that uses dependency injection.

I don’t like those /command actions Slack gives us. I want to be able to chat with a bot like I chat with normal people. This means we need to have a better way to parse interactions with the bot.

When working on the bot-zero-sharp project, the need arose for better handling of enums decorated with a [Flag] attribute. In a previous article we explored how to use Handlebars.NET to generate JSON strings. In this article we’ll build further on that generator to add support for enums. We will also move away from the static JsonHandlebarsDotNet to an injectable version.

I ❤️ Handlebars! So I was very very very happy to see that Handlebars was ported to .NET! It is a mega flexible templating engine as it can easily be extended. I’m currently working on the bot-zero-sharp project and I need to parse objects via JSON templates to JSON strings. This blog will show how to instruct Handlebars to parse into JSON and add some nice error messages if your template fails.

Let’s connect some Ikea TRÅDFRI bulbs to your KAKU ICS-2000. Adding them is not so easy, as the manuals just did not work.

At Wehkamp we ❤️ Slack! Seriously, in order to improve our efficiency, we’ve connected many of our applications, alerts and dashboards to Slack channels. But, as with all things, there is a right way and a wrong way of integrating a webhook at enterprise level.

Let’s explore how easy it is to create an application.

Let’s use a small snippet to convert any article to Markdown. This might come in handy if you want to repost your articles to blogs that support Markdown like DEV.

Let’s run Jupyter notebooks in a Visual Studio Code development container, so we keep our host system clean and our development setup replicable. We’re building a scraper, so let’s add support for Puppeteer (pyppeteer) as well!

Let’s face it: sometimes DateTime is just too much: you only want to deal with dates. Since .NET 6, we finally have support for DateOnly. In this blog I’ll look at how to interact with it and how to add it to your Swagger API docs.

You have a bunch of online services that let you take screenshots of a site and save them in a folder. While it can be very useful to pay for such a system, it is not so hard to create it. Let’s use Chrome / Chromium with Puppeteer and Node.js (cluster) to take some snapshots in no-time. We’ll use the Puppeteer Cluster package to run multiple threads / workers to grab those screens in parallel. We’ll be using TypeScript.
