major

Node, Mark and Extension config options now are strongly typed and do not allow arbitrary keys on the options object.

To add keys, like when using extendNodeSchema or extendMarkSchema, you can do this:

declare module '@tiptap/core' {
  interface NodeConfig {
    /**
     * This key will be added to all NodeConfig objects in your project
     */
    newKey?: string
  }
  interface MarkConfig {
    /**
     * This key will be added to all MarkConfig objects in your project
     */
    newKey?: string
  }
  interface ExtensionConfig {
    /**
     * This key will be added to all ExtensionConfig objects in your project
     */
    newKey?: string
  }
}
