How to copy an image or a text to clipboard in Javascript (new way !) See https://copy-to-clipboard.now.sh/

clipboard.js

// @return Promise<boolean>
async function askWritePermission() {
  try {
    // The clipboard-write permission is granted automatically to pages 
	// when they are the active tab. So it's not required, but it's more safe.
    const { state } = await navigator.permissions.query({ name: 'clipboard-write' })
    return state === 'granted'
  } catch (error) {
    // Browser compatibility / Security error (ONLY HTTPS) ...
    return false
  }
}

// @params blob - The ClipboardItem takes an object with the MIME type as key, and the actual blob as the value.
// @return Promise<void>
const setToClipboard = async blob => {
  const data = [new ClipboardItem({ [blob.type]: blob })]
  await navigator.clipboard.write(data)
}

// Can we copy a text or an image ?
const canWriteToClipboard = await askWritePermission()

// Copy a PNG image to clipboard
if (canWriteToClipboard) {
  const response = await fetch('/image/my-beautiful-image.png')
  const blob = await response.blob()
  await setToClipboard(blob) 
}

// Copy a text to clipboard
if (canWriteToClipboard) {
  const blob = new Blob(['Hello World'], { type: 'text/plain' })
  await setToClipboard(blob)
}

Does it work in IOS as well?

people are so funny.

thanks to the author for the great work!

thank you brother, this is very helpful for me.

Error in askWritePermission: Type '"clipboard-write"' is not assignable to type 'PermissionName'.

Checked what permissions are available and found out that only: "geolocation" | "notifications" | "persistent-storage" | "push" | "screen-wake-lock" | "xr-spatial-tracking" - can be used.

in TypeScript yes @ArtemZolotukh1n, because it has not been added to the dom lib.. But it's working. You can fix by doing :

 const { state } = await navigator.permissions.query({ name: 'clipboard-write' as PermissionName })
