loro-crdt-map

1.13.6

Patch Changes

• a4e6174: Fix undo/redo restoring mergeable map children as regular non-mergeable containers.
• 78f6c8a: Fix a potential deadlock when lazy snapshot loading resolves mergeable container parent depths.

1.13.5

Patch Changes

• 1727258: Improve text insert and snapshot import performance by avoiding duplicate text boundary validation and skipping eager imported change block parsing.

• 52d8168: Recover two per-operation editing slowdowns regressed since 1.11.

  Both are constant-factor regressions on the per-op (auto-commit) editing path
  introduced by the lazy-snapshot work in perf: reduce snapshot read memory retention #985, measured against the 1.11.1
  release.

  1. Every MapHandler/ListHandler/MovableListHandler insert validated its
     value with ensure_no_regular_container_value, which heap-allocated a Vec
     on each call even for scalar values (the common case). A scalar fast-path now
     skips the allocation and traversal entirely. map create 10^4 key:
     ~19.4ms -> ~10.7ms.
  2. The per-op text bounds check (TextHandler::len/len_unicode/len_utf16)
     took two DocState locks — one to check whether the container state was
     decoded, then another to query the length. These are now consolidated into a
     single DocState::get_text_len that takes one lock and one container-store
     lookup. The lazy-snapshot memory behavior is preserved: a still-lazy
     container reads its cached length metadata without materializing the full
     richtext state. bench_text B4 apply (per-op text editing): ~389ms -> ~352ms.

1.13.4

Patch Changes

• 4d577ad: Fix two O(n^2) editing slowdowns.

  1. Editing with UTF-16 / UTF-8 (byte) positions (the default in the JS binding)
     validated each position by materializing the entire [0, pos) prefix string,
     making every insert/delete/splice/mark O(n) and a run of edits O(n^2)
     (regression since 1.12.0). The boundary check now reads the rope's prefix
     caches via the cursor (O(log n)). Unicode-indexed editing was unaffected.
  2. When a subscriber is attached and many edits land on the same container within
     one event batch (e.g. random-position inserts, or many distinct map-key
     writes), building the event cloned the growing accumulated diff on every
     compose — O(n^2) in the number of fragments. The diffs are now composed in
     place. This affected text, map and list events.
  3. Converting a UTF-16 / UTF-8 position within a text chunk to a unicode offset
     scanned the chunk char-by-char, so editing/slicing a large contiguous chunk
     (a big insert, a loaded document, or a long run of typed text that merges into
     one chunk) was O(chunk length) per op. Chunks that contain no astral-plane
     characters (UTF-16) or are pure ASCII (UTF-8) now convert in O(1), covering
     essentially all real-world text (ASCII/Latin/CJK).

1.13.0

Minor Changes

• fa888d8: Add mergeable child containers: child containers created under a map key that converge across peers on concurrent first-write instead of forking. Exposed as ensureMergeable{Counter,Map,List,MovableList,Text,Tree} on LoroMap. A mergeable child lives at a deterministic ContainerID derived from (parent, key, kind), and its visibility is driven by a binary ref the parent map stores at the key, so deletes and kind conflicts resolve through the map's regular LWW. getOrCreateContainer is deprecated for lazy map-child creation; migrate those call sites to ensureMergeable*. setContainer and insertContainer regular semantics are unchanged.

1.12.4

Patch Changes

• a6e23b6: Optimize snapshot export for shallow documents by reusing cached shallow-root state instead of checking out to the shallow root and back to latest.

1.12.2

Patch Changes

• cc587ed: Add a browser package remapping so Vite/Rolldown production builds load WASM without top-level await or circular wasm wrapper chunks.

  Also make the base64 entry easier to bundle with plain esbuild, Rollup, and Next.js Webpack by avoiding static Node builtin require() calls and top-level await in browser bundles.

• 8f57f4c: Reduce memory usage for read-only access to snapshot-imported documents by avoiding unnecessary lazy container state initialization.

1.12.0

Minor Changes

• 7dfda87: Make update imports atomic across oplog and document state application.

  • import and import_json_updates now roll back imported oplog changes when state application fails, so malformed updates do not leave the document with oplog/state divergence.
  • Pending changes that are activated during import are included in the rollback boundary when they can affect state application.
  • Import rollback uses conditional guards to avoid adding fixed overhead to successful detached or no-op imports.

Patch Changes

• 64aa97c: Harden encoding, snapshot, and import paths against malformed input

  • JSON schema import (import_json_updates): out-of-range compressed peer indices now return DecodeError instead of being silently accepted as raw peer IDs; mismatched JsonOpContent vs container type returns DecodeError instead of panicking.
  • Outdated binary encoding decoder (decode_op): malformed op streams (missing delete iterators, type mismatches) now return DecodeDataCorruptionError instead of panicking.
  • Fast snapshot decoder (decode_snapshot_blob_meta): truncated or oversized section lengths now return DecodeDataCorruptionError instead of panicking on slice indexing.
  • Change store KV import (import_all): corrupted VersionVector/Frontiers metadata now returns DecodeDataCorruptionError instead of panicking.
  • Value encoding (LoroValueKind::from_u8, read_str): invalid byte values and invalid UTF-8 now return DecodeDataCorruptionError instead of panicking.
  • LoroDoc::diff(): checkout failures during diff calculation are now propagated as LoroError instead of panicking; state restore uses unwrap() to fail-fast on internal errors.
  • try_get_text/list/map/tree/movable_list/counter: now return None for wrong root container types instead of panicking.
  • Detached list insert out-of-bounds: returns LoroError::OutOfBound instead of panicking.
  • Tree mov_after/mov_before on deleted node: returns TreeNodeDeletedOrNotExist instead of panicking.
  • JsonChange::op_len: empty ops array returns 0 instead of panicking.
  • renew_peer_id: avoids theoretical collision with PeerID::MAX.

• 0977ad1: Fix lock-order panics when JavaScript callbacks re-enter Loro APIs.

  • opCount() no longer reacquires the OpLog lock while the current thread already holds a higher-order lock.
  • LoroText.iter() snapshots text chunks before invoking the user callback, so callback code can safely read or mutate the document.

• ef100e6: Reduce memory spikes when exporting snapshots from shallow documents.

  When a shallow document is re-exported from its existing shallow root with only a small tail of updates, Loro now reuses the stored shallow-root state instead of decoding all containers just to re-encode the same state.

• 933d5d6: feat: add clearRedo and clearUndo methods
  feat(undo): add clearRedo and clearUndo methods #921

• 17dc6c0: Fix several edge-case contract violations in document, text, and JSONPath APIs.

  • JSONPath value(...) comparisons now handle boolean values consistently with other scalar comparisons.
  • Rich text mark expansion now follows ExpandType::Before and ExpandType::Both at documented insertion boundaries.
  • Text delta slicing now validates invalid ranges and UTF-8/UTF-16 boundaries before slicing, and public deltas omit removed-style tombstones after unmarking.
  • Detached list and movable-list out-of-bounds operations now return LoroError::OutOfBound instead of panicking.

1.10.0

Minor Changes

• ce16b52: feat: add sliceDelta method to slice a span of richtext feat: add sliceDelta method to slice a span of richtext #862

  Use text.sliceDelta(start, end) when you need a Quill-style delta for only part of a rich text field (for example, to copy a styled snippet). The method takes UTF-16 indices; use sliceDeltaUtf8 if you want to slice by UTF-8 byte offsets instead.

  import { LoroDoc } from "loro-crdt";
  
  const doc = new LoroDoc();
  doc.configTextStyle({
    bold: { expand: "after" },
    comment: { expand: "none" },
  });
  const text = doc.getText("text");
  
  text.insert(0, "Hello World!");
  text.mark({ start: 0, end: 5 }, "bold", true);
  text.mark({ start: 6, end: 11 }, "comment", "greeting");
  
  const snippet = text.sliceDelta(1, 8);
  console.log(snippet);
  // [
  //   { insert: "ello", attributes: { bold: true } },
  //   { insert: " " },
  //   { insert: "Wo", attributes: { comment: "greeting" } },
  // ]

1.9.0

Minor Changes

• 10a405b: feat: JSONPath rfc9535 feat(jsonpath): rfc9535 #848

  Thanks to @zolero for the thorough implementation of JSONPath support!

  LoroDoc now supports querying and mutating document data using JSONPath, following the RFC 9535 specification.

  🧩 API

  // Execute a JSONPath query on the document
  doc.JSONPath(path: string): any[];
