Vaadin VS Alpine.js

But how do we explain the complexity of the current toolset? This is where the Law of the instrument kicks in: "If the only tool you have is a hammer, it is tempting to treat everything as if it were a nail.". Even if JavaScript was born in the web, JavaScript centered frameworks do not fit properly in the web. That is why we have huge bundles of JavaScript, that is why RSC are necessary (things like RSC were already a thing in Vaadin) and that is how JavaScript became the Birmingham screwdriver.

Off-topic but this blog is using https://vaadin.com, that's the first time I am seeing this framework being used!

But there are frameworks like GWT or Vaadin for Java, but none of them really took off afaik, I've never seen a job posting with either of these.

This small tutorial takes 15 minutes from the start to a working demo. We use Picovoice Porcupine Wake Word Engine to enable a Vaadin-based Java web application.

Are you a long-time Java developer using Spring-related tech stack? Vaadin can bring a fresh brief of the air into your daily development routines.

It’s been 7 years since we deployed our first Vaadin app for production. The whole process has been more than interesting. We developed the application according to an analysis (several modules for the agenda in the field of local government) based on a verbal assignment. The customer started testing on our server and after 2 months found only 3 bugs and requested 2 modifications beyond the original brief. Once implemented, we installed it at the customer’s site. The application started for the first time and is still running :-).

> Slightly off topic, but I found JSF the most productive out of any framework.

In my experience, it has been a horrible technology (even when combined with PrimeFaces) for complex functionality.

When you have a page that has a bunch of tabs, which have tables with custom action buttons, row editing, row expansion, as well as composite components, modal dialogs with other tables inside of those, various dropdowns or autocomplete components and so on, it will break in new ways all the time.

Sometimes the wrong row will be selected, even if you give every element a unique ID, sometimes updating a single table row after AJAX will be nigh impossible, other times the back end methods will be called with the wrong parameters, sometimes your composite components will act in weird ways (such as using the button to close a modal dialog doing nothing).

When used on something simple, it's an okay choice, but enterprise codebases that have been developed for years (not even a decade) across multiple versions will rot faster than just having a RESTful API and some separate SPA (that can be thrown out and rewritten altogether, if need be).

Another option in the space is Vaadin which feels okay, but has its own problems: https://vaadin.com/

Of course, my experiences are subjective and my own.

Did you find an excellent custom element that would make sense in your Vaadin Java web application? Maybe that is a web component that you previously published yourself in npmjs.com?

Alpine.js for reactive frontend

✨ In recent months, I have been developing web projects using GOTTHA stack: Go + Templ + Tailwind CSS + htmx + Alpine.js. As soon as I'm ready to talk about all the subtleties and pitfalls, I'll post it on my social networks.

> But honestly, torn towards htmx but undecided.

We are in the middle of migrating from our monster react application into server rendered pages (with jinja2). The velocity at which we are able to ship and the reduction of complexity has been great so far.

Managing client side state for simple things like (is the dropdown open/closed), listening to keyboard events and such can be done with something like alpine-js [1] without all the baggage that something like react brings.

It appears this is already the trend with JS frameworks too - with server side rendering being the new norm.

Sure, you can use any number of JS-avoidance libraries. I'm a fan of Turbo, and there's also htmx, Unpoly, Alpine, hyperscript, swup, barba.js, and probably others.

Direct DOM, but with a library. Specifically AlpineJS since it follows Vue closely in design practices allowing me to scale into a full web application if necessary (basically swapping to Vue takes minimal work). The Morph plugin is specifically what I like using.

If you want more details on the initial setup I encourage you to take a look at the Part I that covers more of the initial implementation. For this portion, I added Prisma as an ORM, a frontend style library called Tachyons, and AlpineJS to handle any client-side interactions. I did this to avoid needing to add a client-side bundler to the build and instead just rely on plain old module imports to compose the frontend. This is now the default for Rails and it is quite nice to not need any additional build tools for the client.

If you’ve followed our other tutorials, you might be familiar with Alpine.js. It’s a lightweight JavaScript library that allows you to add interactivity to your site without writing a single line of JavaScript. It’s incredibly easy to use, and we’ll show you how to make the animation trigger when the user scrolls to it.

The approach is not new, essentially a variation of Knockout, Alpine, and similar "JS-in-HTML" approaches.
