  • 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

Solid 1.4 (#974)
15e54b5 
* 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

* 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`
