In the demo/starter/slides.md file, the click event for the "Open in Editor" button should use @click="$slidev.nav.openInEditor()" instead of @click="$slidev.nav.openInEditor"!

Because the openInEditor method takes an optional URL string parameter. Using @click="$slidev.nav.openInEditor" would end up passing the $event object as the url parameter.

In the end, clicking the button will seem like nothing happens (only the network will fail with /__open-in-editor?file=xxxrequests).

  async function openInEditor(url?: string) {
    if (!__DEV__)
      return false
    if (url == null) {
      const slide = currentSlideRoute.value?.meta?.slide
      if (!slide)
        return false
      url = `${slide.filepath}:${slide.start}`
    }
    await fetch(`/__open-in-editor?file=${encodeURIComponent(url)}`)
    return true
  }
