I created the error-handling-spring-boot-starter library for Spring Boot because I was unhappy with the default response that Spring Boot 2 provides out-of-the-box.
With Spring Boot 3, there is now support for ProblemDetail and we can have a look on how that changes things.

I started my YouTube channel this week. It was quite something to come to this result, speaking to a camera is quite scary at first, but I think I got a nice result in the end 🙂

Using htmx is a great way to make your Spring Boot with Thymeleaf web application dynamic without page refreshes. Since there are no page refreshes, but transparent AJAX calls going on, it is important to put in error handling code to ensure a good user experience in case something goes wrong. This blog post shows how to do this.

In my blog post of yesterday, I explained how to use Thymeleaf live reload with npm scripts. Quickly after announcing the blog post on Twitter, Oliver Drotbohm asked me why I didn’t just use Spring Boot DevTools instead. A valid question and one I will address in this follow-up post.

UPDATE: I created a follow-up blog Thymeleaf live reload with Spring Boot DevTools that shows a way to have Live Reload with a little less setup work, but some important drawbacks as well in my opionion. Be sure to read both blog posts to get an informed opinion about which path to take. If you want to add Tailwind CSS to your project, go to Thymeleaf live reload with Spring Boot and Tailwind CSS after you applied what is shown here. In my book Taming Thymeleaf I use Gulp to setup the frontend build pipeline and have live reloading during development. For the workshop I gave at Spring I/O 2022 Barcelona, I used a different approach using NPM scripts. This avoids the extra gulp dependency with sometimes things that are not up-to-date anymore.

My error-handling-spring-boot-starter library had its first release almost 2 years ago. The first reported issue came soon after with a request to support Spring WebFlux. As I don’t have any Spring WebFlux projects myself, it was pretty low on my priority list. Especially as it did not seem trivial to add support.
Luckily, about a month ago Fabio Marini opened a PR with all the building blocks I needed to add support for Spring WebFlux to the library.
Version 3.0.0 has now been released which can be used with Spring WebFlux.

I migrated a project from Bootstrap 4 with the Sleek dashboard template to Tailwind CSS as Bootstrap 4 stopped having bugfixes on 2021-07-01, and there is no version for Bootstrap 5. Anyways, I like Tailwind CSS a lot more to work with :)
One of the components that the project used is Bootstrap Toggle, which makes a simple checkbox look a lot better. As the project kicked out Bootstrap, I needed to build a replacement for it. This blog entry will explain how I did so step-by-step using Tailwind CSS and Alpine.js.
