Syntax

Creating Refs

import { createRef } from 'jsx-dom-runtime';

let i = 0;

const ref = createRef();

<document.body>
  <p ref={ref}>{i}</p>
  <button type="button" onClick={() => {
    ref.current.textContent = ++i;
  }}>
    + 1
  </button>
</document.body>;

Callback Refs

<document.body>
  <input ref={(node) => {
    setTimeout(() => node.focus(), 100);
  }} />
</document.body>;

Binding multiple refs

import { bindRef, createRef } from 'jsx-dom-runtime';

const ref = createRef();

const callback = (node) => {
  console.log(ref.current === node); // true
};

<document.body>
  <p ref={bindRef(ref, callback /* ... */)} />
</document.body>;

Parse from string

import { parseFromString } from 'jsx-dom-runtime';

const svg = parseFromString(
  `<svg width="24" height="24" aria-hidden="true">
    <path d="M12 12V6h-1v6H5v1h6v6h1v-6h6v-1z"/>
