- moosteeProposed variant optimised for human readaiblity...```js import mador from "mador"; const [read, write] = mador({ count: 1 }); read(".counter", ctx => ctx.el.textContent = ctx.count); write(".increment", "click", ctx => ctx.count++); write(ctx => ctx.count = 0); ```## ReadDependencies are detected automatically when the read function is run during initiation.```js read(".counter", ctx => ctx.el.textContent = `Count: ${ctx.count}`); ```## WriteImmediate:```js write(ctx => ctx.count++); ```Event-triggered:```js write(".increment", "click", ctx => ctx.count++); ```Event writes expose `ctx.el` and `ctx.event`.
- codedokodeThe syntax looks a bit too verbose for me. And function names like "read" and "write" are confusing too, given that "read" function isn't made for reading values. Cannot we use a single function for binding, like this (and name it "bind")? let counter = proxy({ count: 0 }); bind('.counter', (el) => el.textContent = counter.count); counter.count++; // Queues DOM update Also,> Mador is distributed as an ES module.This means it cannot be used on a page opened from disk, and the user needs to set up a HTTP server which is time-consuming and distracting. And you cannot distribute an app as as HTML file.
- bedroom_jabroniThere are many standalone plug-n-play implementations of the signal primitive in JS. To name a few: preact/signals, vue reactivity, etc, there's even a TC39 proposal for a lang feature. Is this meant to stand out by doing things differently or reinvent them?
- afavourI’m curious to know what performance looks like. In the recesses of my memory is the belief that proxies are not good for performance but I have no idea if that’s well founded (or maybe once was but isn’t any more).It’s a very smart idea though, I like it.
- abosalehworldI love the minimalist approach here. Using Proxies for state management without the heavy overhead of large frameworks is really elegant. Keeping it under 80 lines is impressive. Great work!
- PoignardAzurAre reactive updates based on deep equality or reference equality?
- DylanMerigaudClean launch, good luck!
- ahmedhossamdevGreat work!
- bosmarcelHey HN! I wanted to see how far you can push modern JavaScript Proxies without all the heavy overhead of a traditional framework. The result is Mador: a tiny ~80-line reactive state tuple ([r, w]) that lets you make any DOM element reactive using a simple CSS selector, automated dependency tracking, and batched microtasks. No build steps required—just drop it in. I built this over the weekend just to experiment with clean, zero-dependency reactivity. Would love to hear your thoughts or see where you'd run into limits with something like this!
