Introduction

neta ネタ — Japanese for the topping of sushi, usually the fish part of nigiri, provides a JS-only framework for the modern web. Where other frameworks rely on some special markup language, like JSX, neta provides a simple and easy to use API in plain Javascript. No compilation needed!

Composition

To tell neta how to render a DOM-Element, you provide it with something called a descriptor, which is just a fancy word for an object containing all information about the desired Element. This object will then extend the previously defined descriptor. This way we can add certain properties like styling, attributes, children, etc. on one element and override, mix or extend them in another.

Note: neta relies on the prototype chain to extend partials. This means, property lookups are handled by the browser 🎉

Simple element creation:

neta.document({
    body: html({ text: 'Hello World!' })
});

You can partially apply a descriptor and reuse it:

const div = html({ tag: 'div' });
const red = html({ styles: { color: 'red' } });

neta.document({
    body: div(red)({
        children: [
            div({ text: 'Hello World!' }),
        ],
    }),
});

Components

To abstract certain functionalities you can wrap your descriptor in a function. This allows you to map the properties or make invocations only when you actually need them.

function icon({ url }) {
    // Do something here
    return html({
        tag: 'img',
        attributes: {
            src: url,
        },
        styles: {
            width: '100%',
        },
    });
}

neta.document({
    body: html({
        children: [
            icon({
                url: 'https://picsum.photos/200/300',
            }),
        ],
    }),
});
app.mount(parent);

Reactivity

To let neta keep track of changes you can pass it an observable instead of any attribute, style or child. An observable can be a Promise, a value wrapped in the provided state function, or anything that implements a then function similar to a Promise really.

const time = state();

setInterval(() => {
    time.set(new Date().toLocaleTimeString());
}, 1000);

neta.document({
    body: html({ text: time }),
});
