`hydrate()`

Syntax: hydrate(el, vnode, intersect?)
Example: hydrate(el, vnode)

The hydrate function takes prerendered HTML and patches it with event listeners and necessary content. It accepts an element, a virtual node to model the element, and an optional intersect parameter.

There are two ways to hydrate: intersect and idle. The intersect method is invoked by default, and hydrates the DOM node when it is visible. The idle method only hydrates the DOM node when the main thread is free.

import { _, m, hydrate } from 'million';

// Assume body looks like: <body><button>Say hello!</button></body>
hydrate(
  document.body,
  m('button', { onClick: () => alert('Hello World!') }, ['Say hello!']),
);
