What's Changed

• feat(build): use __DEV__ to control development mode by @dai-shi in #338
• fix(utils): do not depend on react in build by @dai-shi in #358

v1.2.12

This is just a small release to fix a bug in proxyWithHistory util.

What's Changed

Full Changelog: v1.2.11...v1.2.12

v1.2.11

v1.2.10 has two serious issues: a) TS types for useSnapshot and proxyWithComputed are broken. b) derive has a bug. They should be fixed in v1.2.11, but there can still be some bugs. Please feel free to open issues.

What's Changed

• fix(utils): re-implement derive to make glitch free (#335 was buggy) by @Noitidart in #341
• fix(types): workaround for extracting types by @dai-shi in #342

v1.2.10

⚠️ ⚠️ ⚠️ v1.2.10 turns out to have some bugs. Please use v1.2.11 instead. The Migration Guide below is still valid.

---

This adds new proxyMap and fixes derive, both in valtio/utils. The internal DeepResolveType type is deprecated, which might require migration.

Migration Guide (from v1.2.8 and v1.2.9)

In case you need to specify snapshot types, there are two options.

Assert mutable (let's lie)

type State = { foo?: string }
const state = proxy<State>({})

  const snap = useSnapshot(state) as State
  const handleSnap = (s: State) => {
    // ...
  }

as State can be as typeof state.

Wrap types with Readonly<>

type State = { foo?: string }
const state = proxy<State>({})

  const snap = useSnapshot(state)
  const handleSnap = (s: Readonly<State>) => {
    // ...
  }

Readonly<State> can be Readonly<typeof state>

If the state is deeply nested, please define DeepReadonly type util.

type DeepReadonly<T> = {
  readonly [P in keyof T]: DeepReadonly<T[P]>;
}

  const handleSnap = (s: DeepReadonly<State>) => {
    // ...
  }

What's Changed

• feat(utils): add proxyMap by @fkhadra in #330
• fix: avoid const enum and deprecate DeepResolveType by @dai-shi in #333
• fix(utils): make derive glitch free by @dai-shi in #335

v1.2.9

This has small fixes in core, but most notably, it adds a new proxySet util in valtio/utils.
