    Because AI-UI is a JavaScript module, you specify the layout as a series of function calls. However, it also fully supports JSX and htm, so you can use a more familiar markup at the cost of the loss of some type safety. There's more about these choices in the AI-UI guide here.
  • Ask HN: How do you use React as a library in 2024?
    1 project | | 10 May 2024
    I know what "MVC" _stands_ for, but I'm asking what _context_ you mean that in. Are you talking about how to define your server-side data models and endpoints? How you're organizing client-side fetching and caching?

    Normally "MVC" as a concept doesn't get used in the React ecosystem (the way it did with Backbone.js).

    FWIW it's certainly _possible_ to use React as a script tag, but it's extremely rare. It's normally expected that the frontend _is_ actually bundled and compiled, whether it be using a pure-SPA build tool like Vite, or one of the full server-side frameworks like Next or Remix.

    Note that the SPA build output is just a set of static HTML/JS/CSS files, which do not require a separate Node server process for hosting - they can be served by any HTTP server.

    My own advice would be to use Vite and build as an SPA.

    _If_ you absolutely want to use React as _just_ a `` tag with no build step, I'd recommend also using <a href=""></a> to at least give you JSX-like syntax for writing your components.

    So getting this to work without bundler magic is very hard. It's not surprising why NextJS is investing in a bundler. Though one thing that really sticks out is how much complexity we add for just miniscule dev ergonomics. Not using JSX and using something like htm would make all this easier (removing the bundler entirely), it's a lot of overhead to avoid a couple of quotes. React should really have a tagged-template mode. Also all of this is indirection is actually bad for dev ergonomics too! One of the reasons I did this is because I'm absolutely sick of magic caches and sorting through code that's been crushed by a bundler into something I don't recognize and can't easily debug. While we can't get rid of this completely (ts/jsx) this preserves the module import graph completely on the client-side making it easy to find things as you are working and preserving line numbers. This obviously is not useful for a production build and there's a lot of work that would need to go in to support both modes over the same code, but it's depressing no tools really work like this for local development.

    While I was able to achieve this fairly easily, the developer experience of manually stitching strings together wasnt great. Being myself a fan of buildless libraries, such as htm and lit-html, I figured I'd try to take a stab at implementing a DSL for component-like templating in Service Workers myself, called Service Worker Templating Language (SWTL), here's what it looks like:

    If you're going to do a no-build approach, assume modern JS (so you don't have to transpile the JS syntax). Also, you can use as a nearly-identical equivalent to JSX syntax, also without transpiling.

    This seems like a case of caring way too much about something that's hardly very different. JSX versus tagged template strings can be incredibly similar to one another.

    The examples in this article are using vanilla template strings to author raw html, but that only misses a couple of nicities JSX has. There are tagged template string libraries like htm[1] that do include some of the few nicities JSX has, but which are actually compatible with the official language.

    Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

    At the very bottom of the image, there are 3 blocks that I chose to call application components. If you are building a cross-framework library, these can be built with whatever tools you want! Only catch is, all the tools you use to build it, will be needed by everyone consuming it. So choose wisely, and be mindful of how many kilobytes of third party code you will need in order to ship. In Schedule-X, I chose to use Preact. You will probably be fine with most lightweight virtual DOM libraries, and just like with frameworks there are a few to pick from.
