Honeyjs

Honey is a tool that helps to build (mobile) applications with vite and jsx. It requires no (except for vite) external dependencies and is incredibly fast.

THIS TOOL IS IN VERY EARLY STAGES AND SHOUDN'T BE USED IN A PRODUCTION APP YET

App

The entry point of your application is the HoneyApp function, here you can configure everything about it. As of writing this, the only functional configuration is for the page transition.

const App = HoneyApp({
  root: document.querySelector("#app"),
});

Now that you have setup your app, you should render it

App.render(() => (
  <>
    <h1>Hello, world</h1>
  </>
));

This will render the page provided at the current pathname, see routing for more info. Some more properties on app include:

• App.environment wich will return development when using vite or vite dev, and production when your project has been builded.

Events

App.on("load", (e) => { ... });

Using the App.on function you can register an event listener on the app, the callback will then be fired when that event happens. So for example when you register a navigate event listener, it will fire right before the navigation happens, and the event parameter keeps all the data about the event. As well as a event.preventDefault() function, which will stop the event and its reponses when it is called, the event also contains some other values like event.defaultPrevented and event.cancelable.

Pages

This is what a sample page will look like:

export default function () {
  return (
    <>
      <h1>Hello,</h1>
      <p>world</p>
    </>
  );
}

However components also have some special properties, like the preserve keyword. When you switch between pages and you have the same element on both pages with a preserve keyword, that element will not transition, it will be left untouched. This is helpfull when you transition between pages, but you want the navbar to stay the same.

JSX

Honey uses vite's (or esbuild's) builtin jsx transformer alongside a custom jsx parser that transforms it into h functions, which get parsed to native HTML elements by @honeyjs/core/jsx-runtime. The vite config gets automatically updated once @honeyjs/core/plugin is used, however it isn't necessary. The plugin just adds a Hot Module Replacement accept into the main file, wich can be toggled by changing the addHMRAccept property of the first parameter, which will look like this

import { defineConfig } from "vite";
import honey from "@honeyjs/core/plugin";

export default defineConfig({
  plugins: [honey({ addHMRAccept: true })],
});

Reactivity

Honey also exposes some methods for reactivity, which are heavily inspired by solid.js

const [count, setCount] = createSignal(0);

A signal is a reactive variable, you can change it by calling setCount(1), wich will change count to 1.

createEffect(() => {
  console.log(`count was changed to: ${count()}`);
});

An effect is a function that gets called whenever a reactive value used in the effect changes, so when setCount is called and it isn't the same value, every effect that uses count() will be called.

const getUsers = createMemo((id) => {
  users.find((e) => e.id == id);
});

The last method is a memoization function wich when called remembers wich output belongs to wich input. A memoization function is basically a form of caching, wich will improve performance when calling lots of methods multiple times.

NOTE: One drawback is that when using the reactive value in jsx, you have to pass it as a function

<p>count: {count()}</p>         // Won't update the value
<p>count: {() => count()}</p>   // Will update
<p>count: {count}</p>           // This also works
