tiptap_python_utils

TipTap is a JavaScript editor. If your backend is Python and you need to process TipTap JSON — extract text, query tasks, sync shared nodes — this library does it in pure Python with zero dependencies. No JS bridge, no Node.js subprocess.

Quick Start

from tiptap_python_utils import Content

raw = {
    "type": "doc",
    "content": [
        {
            "type": "paragraph",
            "attrs": {"id": "p1"},
            "content": [{"type": "text", "text": "Old"}],
        }
    ],
}

# Strict-load → descend to the text leaf → write a new value → serialize.
updated = Content.require(raw).where_id("p1").leaf().text("New").dump()

Features

• Zero runtime dependencies. Standard library only.
• Python 3.9+. Tested on 3.9, 3.10, 3.11, 3.12, 3.13.
• Lossless round trip. Unknown node kinds and any extra fields are preserved.
• Immutable AST. All mutations return new instances via a fluent selection API.

Install

pip install tiptap_python_utils

Three Ways to Load a Document

Pick a constructor by how much you trust the input — lenient, strict, or auto-wrapping a bare node into a doc.

Constructor	When to use	On invalid input
Content.parse(raw)	Lenient — raw may be None, a string, or a dict	Returns a Content with root=None
Content.require(raw)	Strict — input must be a valid TipTap doc	Raises TiptapValidationError
Content.wrap(node)	Auto-wraps a non-doc node into a doc root	Raises if the node is not parseable

Lossless Round Trip

Parsing never silently drops fields — custom nodes and unknown keys survive a parse-then-serialize cycle byte-for-byte. Two mechanisms preserve information:

• Node.extra stores top-level keys that aren't part of the known schema (e.g. custom node attributes, vendor-specific keys).
• Node.present records which structural keys (attrs, content, …) appeared in the raw input, so raw() emits empty attrs: {} or content: [] only when they were originally present.
• Unknown node kinds become Unknown(raw_kind="…") rather than being rejected.

from tiptap_python_utils import Content

raw = {"type": "doc", "content": [
    {"type": "customPanel", "attrs": {"id": "p1"}, "content": [], "custom": {"x": 1}}
]}

assert Content.require(raw).to_dict() == raw  # byte-for-byte

Typed Nodes

Build typed nodes directly in Python and serialize them back to TipTap-compatible JSON.

from tiptap_python_utils import Content, Paragraph, Text

node = Paragraph(id="p1", content=(Text(value="Hello"),))
doc = Content.wrap(node.raw())

Selection and Editing

The fluent selection API is the single home for mutation: every method returns a new Content, so the original is never mutated.

Select by id or kind

from tiptap_python_utils import Content, kind

# By id (uses TipTap's id resolution rules under the hood).
content.where_id("p1")

# By TipTap kind.
content.of(kind.PARAGRAPH)

# By an arbitrary predicate over every node (and its descendants).
content.where(lambda node: getattr(node, "level", None) == 1)

Generic queries

Selection carries two predicate primitives that work for any kind, so you don't need a bespoke has_heading_text-style helper per node type:

# Narrow a selection further.
content.of(kind.HEADING).filter(lambda n: n.level == 2)

# Existence check (short-circuits).
content.of(kind.HEADING).any(lambda n: n.text.strip() == "Introduction")

Atomic mutations

# Write an attribute on the selected node.
content.where_id("p1").attr("color", "blue")

# Descend to the first text descendant, then write text or marks.
content.where_id("p1").leaf().text("Updated")
content.where_id("p1").leaf().marks([{"type": "bold"}])

# Replace the whole selected node, or append a child to it.
content.where_id("p1").replace({"type": "paragraph", "attrs": {"id": "p1"}, "content": []})
content.where_id("ul1").append({"type": "listItem", "attrs": {"id": "li-new"}, "content": []})

.text() and .marks() are strict — they only operate on Text refs. Chain .leaf() first to descend from a container.

Document-level commands

# Append a node to the document root.
content.append_root({"type": "paragraph", "attrs": {"id": "p2"}, "content": []})

# Build-and-append in one call — works for any kind, stamps a fresh id when
# none is given. Typed fields (e.g. Heading.level) hydrate correctly.
content.append(kind.HEADING, "New section", attrs={"level": 2})
content.append(kind.PARAGRAPH, "Body text", node_id="p3")

# Replace a node by id (the replacement's attrs.id must match).
content.replace_by_id("p1", {
    "type": "paragraph",
    "attrs": {"id": "p1"},
    "content": [{"type": "text", "text": "Replaced"}],
})

Text Extraction

Pull the visible plain text out of a document — useful for search indexing, word counts, or previews.

from tiptap_python_utils import Content, text_slices, visible_text, word_count

content = Content.require(raw)

plain_text = visible_text(content)
count = word_count(content)
slices = text_slices(content, context=True)

Tasks

Query task lists in a document — find every task item or check whether any are still open.

from tiptap_python_utils import Content, has_open_tasks, open_tasks

content = Content.require(raw)

pending = has_open_tasks(content)
items = open_tasks(content)

Each TaskItem exposes derived state as properties:

task = open_tasks(content)[0]

task.task_item_id       # canonical id (falls back to local id)
task.is_completed       # status / checked interpretation
task.is_linked_copy     # True when local id differs from canonical id
task.shared_id          # sharedId attr, if any

Shared-Node Synchronization

Keep copies of the same logical node (linked by sharedId) in sync — collect canonical bodies, then rewrite every matching node from them.

Content.shared_families() collects canonical bodies grouped by sharedId into a SharedFamilies value object. Content.sync_shared(families) rewrites every matching node in the document from those canonical bodies, preserving per-instance identity (id, sharedId). Both return immutable values — the original Content is never mutated.

from tiptap_python_utils import Content

# Canonical doc: the source of truth for every shared body.
canonical = Content.require({"type": "doc", "content": [
    {
        "type": "paragraph",
        "attrs": {"id": "p1", "sharedId": "intro"},
        "content": [{"type": "text", "text": "Authoritative intro"}],
    }
]})

# Doc that mirrors the same sharedId but with a stale body.
target = Content.require({"type": "doc", "content": [
    {
        "type": "paragraph",
        "attrs": {"id": "p1-copy", "sharedId": "intro"},
        "content": [{"type": "text", "text": "Stale copy"}],
    }
]})

synced = target.sync_shared(canonical.shared_families())
assert synced.has_shared("intro")

Related helpers on Content:

• content.where_shared_id(sid) — Selection over every node with that sharedId.
• content.has_shared(sid) — quick presence check.
• node.with_shared_id(sid) — stamp a sharedId onto a node (returns a new node).
• new_shared_id() — mint a fresh shared-… identifier.
