0.11.0 • Public • Published


    H3 is a microframework to build client-side single-page applications (SPAs) in modern JavaScript.

    H3 is also:

    • tiny, less than 4KB minified and gzipped.
    • modern, in the sense that it runs only in modern browsers (latest versions of Chrome, Firefox, Edge & similar).
    • easy to learn, its API is comprised of only seven methods and two properties.

    I'm sold! Where can I get it?

    Here, look, it's just one file:

    Download v0.11.0 (Keen Klingon)

    Or get the minified version here.

    Yes there is also a NPM package if you want to use it with WebPack and similar, but let me repeat: it's just one file.

    Hello, World?

    Here's an example of an extremely minimal SPA created with H3:

    import { h3, h } from "./h3.js";
    h3.init(() => h("h1", "Hello, World!"));

    This will render a h1 tag within the document body, containing the text "Hello, World!".

    Something more complex?

    Have a look at the code of a simple todo list (demo) with several components, a store and some routing.

    No, I meant a real web application...

    OK, have a look at litepad.h3rald.com — it's a powerful notepad application that demonstrates how to create custom controls, route components, forms, and integrate third-party tools. The code is of course on GitHub.

    Can I use it then, no strings attached?

    Yes. It's MIT-licensed.

    What if something is broken?

    Go fix it! Or at least open an issue on the Github repo, pleasy.

    Can I download a copy of all the documentation as a standalone HTML file?

    What a weird thing to ask... sure you can: here!
