* resource and reactive updates, fix #919 * stores: top level arrays, prevent obj overnotify, fixes #960 batching mutable * fix #940 undefined ssr, fix #955 undefined className, fix #958 undefined spread * changelog wip * fix: fix the signal setter type when used with generics (#910) This makes it easier to create generic wrappers around `createSignal` e.g. ```ts function createGenericSignal<T>(): Signal<T | undefined> { const [generic, setGeneric] = createSignal<T>(); const customSet: Setter<T | undefined> = (v?) => setGeneric(v); return [generic, (v?) => setGeneric(v)]; } function createInitializedSignal<T>(init: T): Signal<T> { const [generic, setGeneric] = createSignal<T>(init); const customSet: Setter<T> = (v?) => setGeneric(v); return [generic, (v?) => setGeneric(v)]; } ``` where previously such the implementation would not be assignable to `Setter`, and would need to be cast. Unexpectedly this also makes this more specific: ```ts const [s, set] = createSignal<string>(); // <-- signal contains undefined // before: const v = set(() => "literal"); // ^? - string // after: const v = set(() => "literal"); // ^? - "literal" ``` * refactor: improve splitProps type for arbitrary rest args length (#930) - Allows the return type of splitProps to be correct for 1 or more `...keys` passed - Removes overloads for `splitProps` as they are no longer necessary - Types each array passed as rest args as `readonly` as they do not need to be mutable * v1.4.0-beta.0 * fix: spreading non-object props (#963) - `createComponent` passes an empty object instead of non-object props which are spread - `mergeProps` treats non-object sources as empty objects - added tests fixes #958 * Revised Component types (children, ref) (#877) * Revised Component types (children, readonly, ref) * Rename past `Component` type to `ComponentWithChildren`. Motivation: Most components don't actually support children. This causes a type error upon accidental passing of children / forces you to think about which components support children. * Added second parameter to `ComponentWithChildren` to make it easier to give a custom type for `children` (but still defaults to useful `JSX.Element`). * New `Component` type does not have automatic `children` property (like React's preferred `VoidFunctionalComponent`), offering another natural way to type `props.children`: `Component<{children: JSX.Element}>`. * `props` argument in both `Component` and `ComponentWithChildren` automatically cast to `readonly` (shallow one level only), to avoid accidental assignment to `props.foo` (usually a getter) while still allowing passing mutables in props. Add `Props<T>` helper for this transformation. * Add @lxsmnsyc's `Ref<T>` type so it's easy to type `props.ref`: `Component<{ref: Ref<Element>}>`. <#778 (comment)> Fixes #778. * Fix test * Remove Props helper and shallow Readonly for props * VoidComponent, ParentComponent, FlowComponent * Use Component<any> for generic component type * Add default types, Context.Provider require children Comments from Otonashi * Default parameter for PropsWithChildren * Restore missing <any> * Docs typo fix * Cleanup server code * JSDoc improvements * Improve FlowProps JSDoc * More FlowComponent JSDoc improvements Co-authored-by: Ryan Carniato <[email protected]> * refactor: simplify effect types (#913) - Simplified `createEffect` etc. such that they no longer use rest args - Added test cases for effect functions failing partial generic inference (not supported by typescript) - Removed extra params from effects' first overload * optimize: use jest fake timer to test suspense (#964) fix #761 * new store modifiers splice, modifyMutable, bug fixes * v1.4.0-beta.1 * refactor: remove extra generic from modifyMutable (#965) * fix splice length setting * remove unnecessary splice * feat: resource deferred streaming * v1.4.0-beta.2 * support standard JSX transform * fix #967 `onHydrated` * v1.4.0-beta.3 * Different types for standard transform * v1.4.0-beta.4 * fix solid hyperscript, startTransition cleanup * fix build * v1.4.0-beta.5 * fix synchronous resources * more changelog updates * fix batch consistency in stores * v1.4.0-beta.6 * typescript: correct on helper types (#959) * refactor: correct on helper types - Previous input type now includes undefined, which is its initial value - When defer is true, memos created with the on helper include undefined - Fixed return type becoming unknown when passing a function with a third parameter (the previous type) - Allow readonly arrays/tuples to be passed as deps - Disallow empty arrays from being passed as deps - Breaks backwards compatibility of the first generic; now it is the type of the inputs passed to the function instead of the type of the deps themselves: ```ts // before on<number>(() => 1, ...) // error on<() => number>(() => 1, ...) // ok on<[number]>([() => 1], ...) // error on<[() => number]>([() => 1], ...) // ok // now on<number>(() => 1, ...) // ok on<() => number>(() => 1, ...) // error on<() => number>(() => () => 1, ...) // ok on<[number]>([() => 1], ...) // ok on<[() => number]>([() => 1], ...) // error on<[() => number]>([() => () => 1], ...) // ok ``` * docs: update on helper jsdoc * fix: missing readonly in on helper types' `AccessorTuple` * refactor: allow any array in `AccessorTuple` - So that passing arrays works - Renamed to `AccessorArray` Co-authored-by: Ryan Carniato <[email protected]> Co-authored-by: Xavier Loh <[email protected]> Co-authored-by: Erik Demaine <[email protected]> Co-authored-by: WZT <[email protected]>

@ryansolid removed the
Object.keysthing. I wanted to bring it closer to how native spreads worked but don't think it's feasible. Could also limit the check to== null, or falsy, not sure what the best thing to do is.
