uniqueId

Behaviour takes options 0.18 kB gzipped

Declare the attribute so the schema keeps it.

Without this the id is dropped on the way in: undeclared attributes do not survive, which is a security property rather than an oversight. The id is written to the element as `data-<attribute>` and read back from there, so it survives HTML as well as JSON.

Adding it

import { createEditor, document, paragraph, text, uniqueId } from '@matrajs/core'

const editor = createEditor({
  extensions: [document, paragraph, text, uniqueId({ … })],
  element: document.querySelector('#editor'),
})

There is no separate package · uniqueId is already in @matrajs/core, and an extension you do not import is not in your bundle. document, paragraph and text are the floor every document needs.

Options

Field	Type
`types`	`string[]`	Which node types get an id. Defaults to the blocks in the box.
`attribute`	`string`	The attribute the id is written to.
`generate`	`() => string`	Supply your own, when the ids have to match something outside the editor.
