How to enforce first Node to be heading H1 in tiptap editor?

I am building a simple rich text editor for writing blogs. I want to enforce that first Node always be the title (h1 tag) which user should not be able to delete!

Is there a way to achieve this?

If you're using React, and you don't want to use a custom document as mentioned by @pkid169 or default content, you can use a useEffect hook to set a heading to the editor.

Here's an example:

'use client'

import { EditorContent, useEditor } from '@tiptap/react'
import { StarterKit } from '@tiptap/starter-kit'
import { useState, useEffect } from 'react'

export default function HeaderBlock() {
  const [content, setContent] = useState('')

  const editor = useEditor({
    content,
    editorProps: {
      attributes: {
        class: '...'
      }
    },
    onUpdate: ({ editor }) => {
      setContent(editor?.getText() ?? '')
    },
    extensions: [
      StarterKit,
    ]
  })

  useEffect(() => {
    editor?.commands.setHeading({ level: 1 })
  })

  return (
    <EditorContent editor={editor}/>
  )
}

Extend Document:

const CustomDocument = Document.extend({
  // https://tiptap.dev/api/schema#content
  content: 'heading block*',
})

Load the CustomDocument and add default placeholder for Heading:

  new Editor({
    extensions: [
      CustomDocument,
      Placeholder.configure({
        placeholder: ({ node }) => {
          if (node.type.name === 'heading' && node.attrs.level == 1) {
            return 'H1 placeholder here';
          }
        },
      }),
    ]
  })

After that, you have to find a solution for prevent bold/italic/H2/H3/etc. on your H1. If you have a solution for it, please give the solution in comment.

You can achieve this via Custom Document, where you can define the document structure. Tip tap has an example page here https://tiptap.dev/examples/custom-document.

You could put it in content when initializing:

const editor = useEditor({
  extensions: [
    StarterKit.configure({
      heading: {
        levels: [1, 2],
      },
    }),
    Dropcursor.configure({
      color: "#4B5563",
    }),
    Placeholder.configure({
      showOnlyWhenEditable: true,
      placeholder: "Write something or press Enter to add a new block",
    }),
    CodeBlockLowlight.configure({
      lowlight,
    }),
    TaskList,
    CustomTaskItem,
    ListItem,
    Blockquote,
    CustomOrderedList,
    CustomHorizontalRule,
    Table.configure({
      resizable: true,
    }),
    TableRow,
    TableHeader,
    TableCell,
  ],
  editorProps: {
    attributes: {
      class: "focus:outline-none subpixel-antialiased",
    },
  },
  autofocus: true,

  // THIS
  content: `
    <h1>Hello there </h1>
  `,
})
