Tailwind CSS framework support

[kernelogic]

Hello, I want to use Tailwind CSS framework in my project, is there any guide to it?

I am also interested in using Tailwind CSS with play.

It might be a good idea to generalize that! It would be useful to support Tailwind, Flowbite, and other tools like Vite (or some equivalent) and Svelte (or other equivalents). A very big ask.

I'm working on it, using Tailwind through Flowbite in a Svelte client compiled with Vite. I have tried a few experiments manually with Play (Scala) and they have worked but it is beyond my skill set to create a fully automated system that works with sbt. So I copy stuff from place to place and then compile my sbt project.

Can you give more details what exactly are you doing, like which command you run and what you copy from which source to which target?

I'm still in the early experimental stage, and this is a side project, so it proceeds extremely slowly.

I'm using Svelte and Flowbite (Tailwinds) using Vite to compile my JavaScript, CSS and HTML. I get my front end into a state I like, then I compile with Vite's npm run build. The results get dumped in a directory called dist.

Now move the complied files to the appropriate places in the Play project, changing their names to play equivalents (ex index.html becomes index.scala.html). I have to alter some of js and css links in these files and have to add @()(implicit request: RequestHeader) at the top of the html.scala files. The complied js and css files go to the public folder in the play project.

I've only done this with a very simple single page application so far. I'm now working on my main project. It will be a few more weekends until I am able to move it over.

I have not attempted to work Play's template features yet. I'm really hoping that I can integrate them as they save me a great deal of headaches. I may have to replace them with JSON JavaScript calls which would be unpleasant. I do not now how Svelte will react to having Play template commands in my HTML. I suspect badly as Svelte barfs at so much as a unclosed tag. Svelte and Vite ensure that your HTML is W3C compliant.

Why do this?

Svelte has reduced my client side code by about 1/3 in size and it is a lot easier to work with then any other JavaScript technology stack (including Bootstrap and jQuery). Flowbite-Svelte has mostly masked my incompetence with CSS. And my site will no longer look like a Bootstrap variant. Why Scala - the software I'm writing is for structural engineering (math!) and parallel programming, through the functional paradigm, makes things easier once you get over the steep learning curve. And Play provides a better way to wrap it all up in a single package. Also I want to uses Play's router on the server side, rather then Svelte's on the client side.

If you are interested I'll keep you posted. If I get anywhere I may try to automate the process... but that will be a lot of work with sbt, which I only know a tiny bit about.
