Returning HTML from component

function Hello({ el }) {
  return `Hello, I'm ${el.textContent}! 👋`
}

Outside event example

When you're creating floating UI patterns such as tooltips or modal dialogs, you often need to handle the events "outside" of the target dom. Cell supports this pattern with "on.outside[eventName]".

JS

function OutsideComponent({ el, onOutside }) {
  onOutside("click", () => {
    el.textContent += " outside clicked!"
  })
}

register(OutsideComponent, "js-outside-example")

Prevent default example

If you need to preventDefault or stopPropagation, you can access it via '.e' prop.

JS

function PreventDefaultComponent({ on }) {
  on("click", (e) => {
    e.preventDefault()
    alert("A link is clicked, but the page doesn't move to the target url because the default behavior is prevented ;)")
  });
}

register(PreventDefaultComponent, "js-prevent-default-example")
