In the _posts directory of this blog I have 1247 posts… Some of them are not very good or readable since they are WAY dated - I wrote the first in 2006. During these years I have also used a number of different tools and ways to write the blog (string with Blogger way back when). Much have changed. With the tooling and with me.

One concrete example is that in my code editor now, I have instant and brilliant spell checking. I’m using Code Spell Checker which seems to be the default choice for many.

It’s great but work on one file at the time. I wanted it to work on all my files at the same time. Let me show you how I made that work.

I have just landed a new job! (Super-happy about that and I’ll write a separate post on it later).

But that means that I leave one of the heavier periods in my working life - looking for a job in early 2025. I’m not kidding - there’s been tears and a few screams of frustration, self-doubt and generally low-watermarks of Marcus.

I wanted to write a few words for anyone else that is in the situation, share a few tips and advice that I wish I had. And in some case, had taken, because I heard some of these but didn’t apply them.

Just out of The Meeting, between the president of USA, the President of Ukraine and the American Vice president. Just baffled with what I saw.

After hearing the meta-discussions about what was said by who and how for years now I just realized that we probably will have a discussion about who really was aggressive or really just wanted to cooperate.

I realize that this is something that LLM (large language models) are really well suited to solve. So I tried two. This blog post describes what I did.

I’ve been playing around more with HTMX and one of the really cool features that I think we need to talk more about is the ability to trigger client side events from the server. This is accomplished by using the hx-trigger header and elements on the page can listen for events using hx-trigger: myEvent from body.

This means that it’s easy to inform the client that something has happened and then let the client take appropriate actions. For example, imagine that we put an item in the shopping cart. The server responds with the event SHOPPING_CART_UPDATED. A lot of elements on the page can now update based on this event; counter in the shopping cart, list of “other people also bought”, a banner with discounts etc.

Event driven client side architecture. Just imagine what this could do for micro frontend, where each component might...

HTMX is great! And I really like .NET Minimal APIs. Let’s put it together and see how it works.

When I first thought about creating a backend for HTMX using .NET I went down the rabbit hole of Razor Pages. Which was not great I have to say. That programming model is weird and I don’t like it. But in my spelunking I found Razor Slices which will work great as a template engine.

That means that we have a lightweight and easy to grasp backend with Minimal API and then use Razor Slices to render the HTML.

When I describe what HTMx does to people that has never heard about it I often end up telling them about the good old days when we wrote server-side rendered apps, but sadly that replaced the whole page. And then came SPA frameworks and all you got downloaded in the first page access was a <div id="app></div>, then the app got rendered by JavaScript from JSON and the whole concept of the web, HTTP and REST got lost.

HTMx marries these two together. But showing the main.ejs as it stands right now reminds me too much about the old days. Let’s clean it up, and we will soon see that it will look much like a modern SPA, with the huge difference that it is using server rendered HTML that and is easy to grasp.

This is the fifth post in a series that I’m making about HTMx that I think is utterly amazing and will change how I (we?) write web apps in the future.

You are more than welcome to read from here, but then I would recommend getting the code from this point, if you intend to type along.

The application is working fine, but there’s zero validation in place. I wanted to do some simple validation on the client (and here I have a bug) and then also show how to do validation on the server-side and return an error message from there.

Validation can be tricky and often lead to a lot of code. But it’s an obvious addition to the code.

This is the fourth post in a series that I’m making about HTMx that I think is utterly amazing and will change how I (we?) write web apps in the future. You are more than welcome to read from here, but it will be hard following along code-wise if you haven’t stepped through part I, part II and part III first.

In the last part we built out most the actual application, which means that we are left with the fun part here. There’s one section of the application that is not working yet - the footer. In the footer I wanted to show a tally of the number of items, the number of completed items, and also the number of late items.

Keeping track of numbers like that can be a bit messy since we need to update them when we are doing other actions, like...

This is the third post in a series that I’m making about HTMx that I think is utterly amazing and will change how I (we?) write web apps in the future. You are more than welcome to read from here, but it will be hard following along code-wise if you haven’t stepped through part I and part II first

In this part we will build the core logic of the application and start to create todo-items and store them in Firestore.

This is the second post in a series that I’m making about HTMx that I think is utterly amazing and will change how I (we?) write web apps in the future. You are more than welcome to read from here, but it will be hard following along code-wise if you haven’t stepped through part I

In this part we will allow our users to sign in with Google.
