Baracuda

A tiny (400B), modern and fast utility around hyperscript like view layer

Why?

Mostly code readability and DX. h1('Hello world') is easier to understand (for me that is) than h('h1', {}, 'Hello world'). It comes in handy when you have nested childrens.

ul([li('First item'), li('Second item')]);

There was other options but they seemed a little on the heavy side. I wanted something modern and slick.

How?

Proxy.

Installation

npm install @amoutonbrady/baracuda
or
yarn add @amoutonbrady/baracuda

Usage

Import the baracuda factory function and wrap it around an hyperscript like function.

According to tests, baracuda should be at least compatible with the following frameworks:

• Vue 3: import { h } from 'vue'
• Hyperapp: import { h } from 'hyperapp'
• Preact: import { h } from 'preact'
• Inferno: import { h } from 'inferno-hyperscript'
• Redom: import { el } from 'redom'

You can find more example in the tests directory

The hyperscript like function has to take 3 arguments :

h(tag: string, attributes: Object, childrens: string | Element | Element[])

The return object from baracuda is a Proxy that can be destructed into functions with the following interface:

fn(attributes: Object, childrens: string | Element | Element[]): Element
fn(childrens: string | Element | Element[]): Element

Where:

• fn is the name of the tag (eg: div, h1, etc.)
• attributes is an object containing dom attributes (eg: classes, event handler, etc.)
• childrens is either a string or an array of Element

⚠️ If the first argument is not an object, it will be interpreted as the childrens argument and defaulting the attributes to {}

Example

note: the library exports a default function as well as a named function

Quick example

import { h, render } from 'my-dom-library';
import { baracuda } from '@amoutonbrady/baracuda';
// import hh from '@amoutonbrady/baracuda'; <= That also works

const { ul, li } = baracuda(h);

const app = ul([
    li(1),
    li(2),
]);

render(app, document.body);

Limitations

This utility is based on an non polyfillable feature: Proxy. This can't be used in a non evergreen browser.

See MDN for the full compatibility list. I only use the handler.get feature.

Mithril is only partially compatible for the moment.

Roadmap

• [x] ~Typescript support~ Better Typescript support
• [ ] Add helpers, like classes, id
• [ ] More tests

Aknowledgment

• This issue started it all
• Hyperapp which is the framework I had in mind while prototyping this
