babel-plugin-jsx-to-dom v0.6.1

babel-plugin-jsx-to-dom

Normally if you use JSX, you have to use React. You must add: babel-plugin-syntax-jsx to your project to use this.

This supports namespaces which you can add by specifying the element(s)'s namespaces with a namespace="" attribute.

Installation

$ npm install babel-plugin-jsx-to-dom

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": ["babel-plugin-syntax-jsx", "babel-plugin-jsx-to-dom"]
}

Via CLI

$ babel --plugins syntax-jsx,include script.js

Via Node API

require('babel').transform('code', {
  plugins: ['syntax-jsx', 'jsx-to-dom']
});

Example

input:

let a = <p>hi</p>

output:

let a = function() {
  const _elem = document.createElement("p");
  _elem.appendChild(document.createTextNode("hi"));
  return _elem;
}()

This also supports more complex senarios:

function makeTemplate(name, opts) {
    return (
        <div {...opts}>{ name }</div>
    );
}

output:

function makeTemplate(name, opts) {
    return function() {
        const _elem = document.createElement("div");
        let _attrs = opts;

        for (_attr in _attrs) if (_attrs.hasOwnProperty(_attr))
            _elem.setAttribute(_attr, _attrs[_attr]);

        const _expr = name, _res = (typeof _expr == "string" ? document.createTextNode(_expr) : _expr);

        if (_res instanceof Array) {
            for (let _i = 0; _i < _res.length; _i += 1) _elem.appendChild(
                (typeof _res[_i] == "string" ? document.createTextNode(_res[_i]) : _res[_i])
            );
        } else
            _elem.appendChild(_res);

        return _elem;
    }();
}

Namespaces

This supports namespaces. Provide a namespace="<namespace>" attribute

Setting raw attributes

This supports setting attributes not through setAttribute but as a property of the element. So:

<video unsafe-playbackRate={playbackRate} />

Would output

var video = document.createElement('video');
video.playbackRate = playbackRate;

Without the unsafe- this would have generated:

var video = document.createElement('video');
video.setAttribute('playbackRate', playbackRate);

Preventing whitespace from being added

Normally if you have:

<div>
  <elem />
  <elem />
</div>

The whitepace will be added as a node. You can change this by setting the noWhitespaceOnly option to true.

Defaulting null/undefined

Normally if you pass null or undefined to an attribute it won't treat it specially. This behavior is:

nullValues: false,
undefinedValues: false

Setting these to true will prevent the attributes from being set in these cases
