Release Notes

RebeccaStevens/deepmerge-ts (deepmerge-ts)

v8.0.2

Compare Source

Bug Fixes

• correct node engine requirement to >=16.9.0 (ef54ea6)

v8.0.1

Compare Source

Bug Fixes

• typescript 7 support (#​714) (b307b77)

v8.0.0

Compare Source

Bug Fixes

• stop deepmergeInto from leak-mutating nested input containers (2cd7824)

Code Refactoring

• rename mergeInfo system and align shorthand, add JSDoc examples (590ed9b)

Features

• add circular reference support, maxDepth option, and hierarchy tracking (#​707) (3984927)
• add deepmergeFastUnsafe and deepmergeIntoFastUnsafe entrypoints (#​708) (df9b11c)
• support deep map value merging (ac4bf7a), closes #​705

Performance Improvements

• add a dedicated fast path for merging 2 records (4dbcea7)
• avoid array reallocation when no undefined values exist (99f2241), closes #​696
• optimize array and set merging (8d435f9), closes #​698
• optimize map merging and remove dead code (14e1604), closes #​702
• optimize record key and type detection (fa85462), closes #​694
• reduce benchmark sample count so the bench fits in 512MB heap (66635e3)
• reduce type-level work and shortcut same-type merges (473a971)
• speed up the mergeUnknowns hot path (95b2964), closes #​699

BREAKING CHANGES

• deepmergeInto no longer leak-mutates input containers.
  Code that depended on inputs being merged into the target through alias
  must now pass copies explicitly. The documented 'update the target'
  behavior is preserved on the target itself.
• • DeepMergeMetaMetaData has been renamed to DeepMergeMergeInfo. Imports
    must be updated.

• The MetaDataUpdater callback's metaMeta parameter is now mergeInfo.
  Implementations must update the parameter name accordingly.
• The MM generic shorthand has been renamed to MI (e.g. in
  MetaDataUpdater<M, MI>).

• The DeepMergeIntoFunctionUtils type has been renamed to DeepMergeIntoUtils.
• Updates the internal calculation logic for mergeMaps and
  mergeMapsInto. Colliding keys will now be merged.
