Tailwind CSS can now be used without Node (details: https://tailwindcss.com/blog/standalone-cli). Other frameworks like Phoenix and Rails already provide support for this new Node-less Tailwind, with Rails creator DHH being particulary excited about it. Both he and Phoenix creator Chris McCord are gradually trying to wean their frameworks off Node completely. This is a nice process of simplification – why use Node if you don't have to?
If this feature gets implemented, I then have a secondary suggestion for IHP: make Tailwind CSS the default styling framework rather than Bootstrap. As a frontend dev myself, I contend that while Bootstrap SEEMS easier at first than Tailwind, if you're a backend dev you will never feel properly in control of your CSS with Bootstrap. Whereas with Tailwind, if you are prepared to put some effort into improving at CSS (which Tailwind helps enormously with by the way - speaking from personal experience), you can take full control of the styling in your apps, and making changes to that styling become far easier. This is an initially slightly harder path to take, but with far better long-term rewards.
Happy to discuss this more here, and would be interested to hear other points of view.
