apprun VS butterfloat

You can find the source code here and the compiled code here

You can just use npm and ship node_modules on your website. It's probably "huge" so you probably want to clean out dev dependencies first (`npm prune --omit=dev` is one way to clean that) and you might find it useful to search for big binaries to filter out and redundant directories that you don't need (libraries that still include all of UMD and CommonJS and ESM builds even though you only need one), and there may still be libraries that don't directly load in the browser and you need to spot bundle with a tool like esbuild to a vendor directory.

Mostly the only other glue you need after that is an import map.

I find this flow useful (ship an optionally pruned node_modules, spot build specific vendor libraries, add import map), especially for lightweight development/testing, and so I did document it specifically from start to finish for one of my projects, it includes a vendor build one-liner:

(The Example section after the Dev Environment one shows the import map at the top of the example HTML if you are looking for that. I forgot that's where it was when re-reading this.)

Vanilla JS is better these days than when React first arrived. ES Modules are natively supported in browsers now and give you much of a component system.

Though to be fair, rather than using Vanilla JS alone I did recently write my own React-looking but not React-like view engine: https://worldmaker.net/butterfloat/#/

I've been taking a similar, but somewhat different approach to upgrading some old Knockout projects to mostly Vanilla JS+RxJS.

Here's one example app: https://github.com/WorldMaker/compradprog/blob/main/main.tsx

One of the obvious differences is that I'm still using TSX, but it is very different from React, it just looks a lot like React at first glance.

Also, because I was doing it across at least a couple of projects, I started it from the beginning as its own small framework and have been trying to document it: https://github.com/WorldMaker/butterfloat/tree/main

It's still very much in early "prerelease" stages, but feedback is welcome.

Just because on most modern hardware file I/O has millisecond latency and feels synchronous doesn't mean it is synchronous. It might feel like overkill to use Observables instead of Promises and I/O event loops or even thread-blocking faux synchronous file system calls, but there is still an asynchronous world there where it can be nice to have the full power of Observables. To be fair, my love affair with Observables started in C# in "backend" applications, so that's always been the natural fit for me and frontend and UI work has been the "side hustle" of taking stuff that I love in the backend side of the house and putting it to even more use.

I'm calling my view engine Butterfloat, and I only just finished the first documentation pass, so be gentle, but feedback is very welcome: https://github.com/WorldMaker/butterfloat
