v7.0.1

Compare Source

Bug Fixes

• Add missing type current for pre-TS 3.7 types (7d6b57b)

v7.0.0

Compare Source

• Introduced current, which takes a snapshot of the current state of a draft and finalizes it (but without freezing). Current is a great utility to print the current state during debugging (no Proxies in the way), and the output of current can also be safely leaked outside the producer. Implements #​441, #​591

• [BREAKING CHANGE] getters and setters are now handled consistently: own getters and setters will always by copied into fields (like Object.assign does), inherited getters and setters will be left as-is. This should allow using Immer directly on objects that trap their fields, like done in Vue or MobX. Fixes #​584, #​439, #​593, #​558

• [BREAKING CHANGE] produce no longer accepts non-draftable objects as first argument

• [BREAKING CHANGE] original can only be called on drafts and will throw otherwise (fixes #​605)

• [BREAKING CHANGE] non-enumerable and symbolic fields will never be frozen

• [BREAKING CHANGE] the patches for arrays are now computed differently to fix some scenarios in which they were incorrect. In some cases they will be more optimal now, in other cases less. Especially splicing / unshifting items into an existing array might result in a lot of patches. Fixes #​468

• Improved documentation in several areas, there is now a page for typical update patterns and a separate page on how to work with classes. And additional performance tips have been included. Fixes #​457, #​115, #​462

• Fixed #​462: All branches of the produced state should be frozen

• Fixed #​588: Inconsistent behavior with nested produce

• Fixed #​577: Immer might not work with polyfilled symbols

• Fixed #​514, #​609: Explicitly calling useProxies(false) shouldn’t check for the presence of Proxy.
