BlockSuite API Documentation / @blocksuite/store / Y / Text

Class: Text

Type that represents text with formatting information.

This type replaces y-richtext as this implementation is able to handle block formats (format information on a paragraph), embeds (complex elements like pictures and videos), and text formats (bold, italic).

Constructors

new Text(string)
