placeholder: string | ((state: EditorState) => string)

The placeholder to use. It can be a static string or a function that receives the current editor state and returns a string.

strategy?: "doc" | "block" | ((state: EditorState) => boolean)

By default, the placeholder text will be shown whenever the current text cursor is in an empty text node and it’s not inside a code block or a table node.

If you only want to show the placeholder when the whole doc is empty, you can set this option to ‘doc’.

You can also pass a function that receives the current editor state and returns a boolean value to determine whether the placeholder should be shown.

Default: 'block'

function definePlaceholder(options: PlaceholderOptions): PlainExtension

Add a placeholder text to the editor when the current block or document is empty.
