Variables

variable Children

const Children: {
    map<T, C>(
        children: C | readonly C[],
        fn: (child: C, index: number) => T
    ): C extends null ? C : Exclude<T, boolean>[];
    forEach<C>(
        children: C | readonly C[],
        fn: (child: C, index: number) => void
    ): void;
    count(children: any): number;
    only<C>(children: C): C extends any[] ? never : C;
    toArray(
        children: ReactNode | ReactNode[]
    ): Array<Exclude<ReactNode, boolean | null | undefined>>;
};

variable Fragment

const Fragment: ExoticComponent<{ children?: ReactNode | undefined }>;

Lets you group elements without a wrapper node.

Example 1

import { Fragment } from 'react';

<Fragment>
  <td>Hello</td>
  <td>World</td>
</Fragment>

Example 2

// Using the <></> shorthand syntax:

<>
  <td>Hello</td>
  <td>World</td>
</>

variable Profiler

const Profiler: ExoticComponent<ProfilerProps>;

Lets you measure rendering performance of a React tree programmatically.
Example 1
<Profiler id="App" onRender={onRender}> <App /> </Profiler>
See Also

variable StrictMode

const StrictMode: ExoticComponent<{ children?: ReactNode | undefined }>;

Lets you find common bugs in your components early during development.
Example 1
import { StrictMode } from 'react'; <StrictMode> <App /> </StrictMode>
See Also

variable Suspense

const Suspense: ExoticComponent<SuspenseProps>;

Lets you display a fallback until its children have finished loading.

Example 1

import { Suspense } from 'react';

<Suspense fallback={<Loading />}>
  <ProfileDetails />
</Suspense>

variable UNDEFINED_VOID_ONLY

const UNDEFINED_VOID_ONLY: Symbol;

variable unstable_SuspenseList

const unstable_SuspenseList: ExoticComponent<SuspenseListProps>;

SuspenseList helps coordinate many components that can suspend by orchestrating the order in which these components are revealed to the user.
When multiple components need to fetch data, this data may arrive in an unpredictable order. However, if you wrap these items in a SuspenseList, React will not show an item in the list until previous items have been displayed (this behavior is adjustable).

- https://reactjs.org/docs/concurrent-mode-patterns.html#suspenselist

variable unstable_ViewTransition

const unstable_ViewTransition: ExoticComponent<ViewTransitionProps>;

Opt-in for using in React. View Transitions only trigger for async updates like startTransition, useDeferredValue, Actions or <Suspense> revealing from fallback to content. Synchronous updates provide an opt-out but also guarantee that they commit immediately which View Transitions can't.

variable version

const version: string;

Functions

function act

act: {
    (callback: () => VoidOrUndefinedOnly): void;
    <T>(callback: () => T | Promise<T>): Promise<T>;
};

Wrap any code rendering and triggering updates to your components into act() calls.
Ensures that the behavior in your tests matches what happens in the browser more closely by executing pending useEffects before returning. This also reduces the amount of re-renders done.
Parameter callback
A synchronous, void callback that will execute as a single, complete React commit.

        props?: Partial<P> & Attributes,
        ...children: ReactNode[]
    ): FunctionComponentElement<P>;
    <P, T extends Component<P, any, any>>(
        element: CElement<P, T>,
        props?: Partial<P> & ClassAttributes<T>,
        ...children: ReactNode[]
    ): CElement<P, T>;
    <P>(

        props?: Partial<P> & Attributes,
        ...children: ReactNode[]
    ): ReactElement<P, string | JSXElementConstructor<any>>;
};

function createContext

createContext: <T>(defaultValue: T) => Context<T>;

Lets you create a Context that components can provide or read.
Parameter defaultValue
The value you want the context to have when there is no matching Provider in the tree above the component reading the context. This is meant as a "last resort" fallback.
Example 1
import { createContext } from 'react'; const ThemeContext = createContext('light'); function App() { return ( <ThemeContext value="dark"> <Toolbar /> </ThemeContext> ); }
See Also

function createElement

createElement: {
    (
        type: 'input',
        props?:
            | (InputHTMLAttributes<HTMLInputElement> &
                  ClassAttributes<HTMLInputElement>)
            | null,
        ...children: ReactNode[]
    ): DetailedReactHTMLElement<
        InputHTMLAttributes<HTMLInputElement>,
        HTMLInputElement
    >;
    <P extends HTMLAttributes<T>, T extends HTMLElement>(
        type: HTMLElementType,
        props?: ClassAttributes<T> & P,
        ...children: ReactNode[]
    ): DetailedReactHTMLElement<P, T>;
    <P extends SVGAttributes<T>, T extends SVGElement>(
        type: SVGElementType,
        props?: ClassAttributes<T> & P,
        ...children: ReactNode[]
    ): ReactSVGElement;
    <P extends DOMAttributes<T>, T extends Element>(
        type: string,
        props?: ClassAttributes<T> & P,
        ...children: ReactNode[]
    ): DOMElement<P, T>;
    <P extends {}>(
        type: FunctionComponent<P>,
        props?: Attributes & P,
        ...children: ReactNode[]
    ): FunctionComponentElement<P>;
    <
        P extends {},
        T extends Component<P, any, any>,
        C extends ComponentClass<P, any>
    >(
        type: ClassType<P, T, C>,
        props?: ClassAttributes<T> & P,
        ...children: ReactNode[]
    ): CElement<P, T>;
    <P extends {}>(
        type: string | FunctionComponent<P> | ComponentClass<P, any>,
        props?: Attributes & P,
        ...children: ReactNode[]
    ): ReactElement<P, string | JSXElementConstructor<any>>;
};

function createRef

createRef: <T>() => RefObject<T | null>;

function experimental_taintObjectReference

experimental_taintObjectReference: (
    message: string | undefined,
    object: Reference
) => void;

function experimental_taintUniqueValue

experimental_taintUniqueValue: (
    message: string | undefined,
    lifetime: Reference,
    value: TaintableUniqueValue
) => void;

function experimental_useEffectEvent

experimental_useEffectEvent: <T extends Function>(event: T) => T;

function forwardRef

forwardRef: <T, P = {}>(
    render: ForwardRefRenderFunction<T, PropsWithoutRef<P>>
) => ForwardRefExoticComponent<PropsWithoutRef<P> & RefAttributes<T>>;

Lets your component expose a DOM node to a parent component using a ref.

Parameter render

See the ForwardRefRenderFunction.

T The type of the DOM node. P The props the component accepts, if any.

Example 1

interface Props {
  children?: ReactNode;
  type: "submit" | "button";
}

export const FancyButton = forwardRef<HTMLButtonElement, Props>((props, ref) => (
  <button ref={ref} className="MyClassName" type={props.type}>
    {props.children}
  </button>
));

function isValidElement

isValidElement: <P>(
    object: {} | null | undefined
) => object is ReactElement<P, string | JSXElementConstructor<any>>;

function lazy

lazy: <T extends ComponentType<any>>(
    load: () => Promise<{ default: T }>
) => LazyExoticComponent<T>;

Lets you defer loading a component’s code until it is rendered for the first time.
Parameter load
A function that returns a Promise or another thenable (a Promise-like object with a then method). React will not call load until the first time you attempt to render the returned component. After React first calls load, it will wait for it to resolve, and then render the resolved value’s .default as a React component. Both the returned Promise and the Promise’s resolved value will be cached, so React will not call load more than once. If the Promise rejects, React will throw the rejection reason for the nearest Error Boundary to handle.
Example 1
import { lazy } from 'react'; const MarkdownPreview = lazy(() => import('./MarkdownPreview.js'));
See Also

function memo

memo: {
    <P extends object>(
        Component: FunctionComponent<P>,
        propsAreEqual?: (prevProps: Readonly<P>, nextProps: Readonly<P>) => boolean
    ): NamedExoticComponent<P>;
    <T extends ComponentType<any>>(
        Component: T,
        propsAreEqual?: (
            prevProps: Readonly<ComponentProps<T>>,
            nextProps: Readonly<ComponentProps<T>>
        ) => boolean
    ): MemoExoticComponent<T>;
};

Lets you skip re-rendering a component when its props are unchanged.
Parameter Component
The component to memoize.
Parameter propsAreEqual
A function that will be used to determine if the props have changed.
Example 1
import { memo } from 'react'; const SomeComponent = memo(function SomeComponent(props: { foo: string }) { // ... });
See Also

function startTransition

startTransition: (scope: TransitionFunction) => void;

Similar to useTransition but allows uses where hooks are not available.
Parameter callback
A function which causes state updates that can be deferred.

function unstable_useCacheRefresh

unstable_useCacheRefresh: () => () => void;

function unstable_useSwipeTransition

unstable_useSwipeTransition: <Value>(
    previous: Value,
    current: Value,
    next: Value
) => [value: Value, startGesture: StartGesture];

function use

use: <T>(usable: Usable<T>) => T;

function useActionState

useActionState: {
    <State>(
        action: (state: Awaited<State>) => State | Promise<State>,
        initialState: Awaited<State>,
        permalink?: string
    ): [state: Awaited<State>, dispatch: () => void, isPending: boolean];
    <State, Payload>(
        action: (state: Awaited<State>, payload: Payload) => State | Promise<State>,
        initialState: Awaited<State>,
        permalink?: string
    ): [
        state: Awaited<State>,
        dispatch: (payload: Payload) => void,
        isPending: boolean
    ];
};

function useCallback

useCallback: <T extends Function>(callback: T, deps: DependencyList) => T;

useCallback will return a memoized version of the callback that only changes if one of the inputs has changed.
16.8.0
See Also
- https://react.dev/reference/react/useCallback

function useContext

useContext: <T>(context: Context<T>) => T;

Accepts a context object (the value returned from React.createContext) and returns the current context value, as given by the nearest context provider for the given context.
16.8.0
See Also
- https://react.dev/reference/react/useContext

function useDebugValue

useDebugValue: <T>(value: T, format?: (value: T) => any) => void;

useDebugValue can be used to display a label for custom hooks in React DevTools.
NOTE: We don’t recommend adding debug values to every custom hook. It’s most valuable for custom hooks that are part of shared libraries.
16.8.0
See Also
- https://react.dev/reference/react/useDebugValue

function useDeferredValue

useDeferredValue: <T>(value: T, initialValue?: T) => T;

Returns a deferred version of the value that may “lag behind” it.
This is commonly used to keep the interface responsive when you have something that renders immediately based on user input and something that needs to wait for a data fetch.
A good example of this is a text input.
Parameter value
The value that is going to be deferred
Parameter initialValue
A value to use during the initial render of a component. If this option is omitted, useDeferredValue will not defer during the initial render, because there’s no previous version of value that it can render instead.
See Also
- https://react.dev/reference/react/useDeferredValue

function useEffect

useEffect: (effect: EffectCallback, deps?: DependencyList) => void;

Accepts a function that contains imperative, possibly effectful code.
Parameter effect
Imperative function that can return a cleanup function
Parameter deps
If present, effect will only activate if the values in the list change.
16.8.0
See Also
- https://react.dev/reference/react/useEffect

function useId

useId: () => string;

function useImperativeHandle

useImperativeHandle: <T, R extends T>(
    ref: Ref<T> | undefined,
    init: () => R,
    deps?: DependencyList
) => void;

useImperativeHandle customizes the instance value that is exposed to parent components when using ref. As always, imperative code using refs should be avoided in most cases.
useImperativeHandle should be used with React.forwardRef.
16.8.0
See Also
- https://react.dev/reference/react/useImperativeHandle

function useInsertionEffect

useInsertionEffect: (effect: EffectCallback, deps?: DependencyList) => void;

Parameter effect
Imperative function that can return a cleanup function
Parameter deps
If present, effect will only activate if the values in the list change.
See Also
- https://github.com/facebook/react/pull/21913

function useLayoutEffect

useLayoutEffect: (effect: EffectCallback, deps?: DependencyList) => void;

The signature is identical to useEffect, but it fires synchronously after all DOM mutations. Use this to read layout from the DOM and synchronously re-render. Updates scheduled inside useLayoutEffect will be flushed synchronously, before the browser has a chance to paint.
Prefer the standard useEffect when possible to avoid blocking visual updates.
If you’re migrating code from a class component, useLayoutEffect fires in the same phase as componentDidMount and componentDidUpdate.
16.8.0
See Also
- https://react.dev/reference/react/useLayoutEffect

function useMemo

useMemo: <T>(factory: () => T, deps: DependencyList) => T;

useMemo will only recompute the memoized value when one of the deps has changed.
16.8.0
See Also
- https://react.dev/reference/react/useMemo

function useOptimistic

useOptimistic: {
    <State>(passthrough: State): [
        State,
        (action: State | ((pendingState: State) => State)) => void
    ];
    <State, Action>(
        passthrough: State,
        reducer: (state: State, action: Action) => State
    ): [State, (action: Action) => void];
};

function useReducer

useReducer: {
    <S, A extends AnyActionArg>(
        reducer: (prevState: S, ...args: A) => S,
        initialState: S
    ): [S, ActionDispatch<A>];
    <S, A extends AnyActionArg>(
        reducer: (prevState: S, ...args: A) => S,
        initialState: S
    ): [S, ActionDispatch<A>];
    <S, I, A extends AnyActionArg>(
        reducer: (prevState: S, ...args: A) => S,
        initialArg: I,
        init: (i: I) => S
    ): [S, ActionDispatch<A>];
};

An alternative to useState.
useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values. It also lets you optimize performance for components that trigger deep updates because you can pass dispatch down instead of callbacks.
16.8.0
See Also
- https://react.dev/reference/react/useReducer

function useRef

useRef: {
    <T>(initialValue: T): RefObject<T>;
    <T>(initialValue: T): RefObject<T>;
    <T>(initialValue: T): RefObject<T>;
};

useRef returns a mutable ref object whose .current property is initialized to the passed argument (initialValue). The returned object will persist for the full lifetime of the component.
Note that useRef() is useful for more than the ref attribute. It’s handy for keeping any mutable value around similar to how you’d use instance fields in classes.
16.8.0
See Also
- https://react.dev/reference/react/useRef

function useState

useState: {
    <S>(initialState: S | (() => S)): [S, Dispatch<SetStateAction<S>>];
    <S = undefined>(): [S, Dispatch<SetStateAction<S>>];
};

Returns a stateful value, and a function to update it.
16.8.0
See Also
- https://react.dev/reference/react/useState

function useSyncExternalStore

useSyncExternalStore: <Snapshot>(
    subscribe: (onStoreChange: () => void) => () => void,
    getSnapshot: () => Snapshot,
    getServerSnapshot?: () => Snapshot
) => Snapshot;

Parameter subscribe
Parameter getSnapshot

function useTransition

useTransition: () => [boolean, TransitionStartFunction];

Allows components to avoid undesirable loading states by waiting for content to load before transitioning to the next screen. It also allows components to defer slower, data fetching updates until subsequent renders so that more crucial updates can be rendered immediately.
The useTransition hook returns two values in an array.
The first is a boolean, React’s way of informing us whether we’re waiting for the transition to finish. The second is a function that takes a callback. We can use it to tell React which state we want to defer.
**If some state update causes a component to suspend, that state update should be wrapped in a transition.**
See Also
- https://react.dev/reference/react/useTransition

Classes

class Component

class Component<P, S> {}

constructor

constructor(props: {});

property context

context: {};

If using the new style context, re-declare this in your class to be the React.ContextType of your static contextType. Should be used with type annotation or static contextType.
Example 1
static contextType = MyContext // For TS pre-3.7: context!: React.ContextType<typeof MyContext> // For TS 3.7 and above: declare context: React.ContextType<typeof MyContext>
See Also

property contextType

static contextType?: Context<any>;

If set, this.context will be set at runtime to the current value of the given Context.

Example 1

type MyContext = number
const Ctx = React.createContext<MyContext>(0)

class Foo extends React.Component {
  static contextType = Ctx
  context!: React.ContextType<typeof Ctx>
  render () {
    return <>My context's value: {this.context}</>;
  }
}

property props

readonly props: Readonly<P>;

property propTypes

static propTypes?: any;

Ignored by React.
Deprecated
Only kept in types for backwards compatibility. Will be removed in a future major release.

interface RefAttributes

interface RefAttributes<T> extends Attributes {}

The props any component accepting refs can receive. Class components, built-in browser components (e.g. div) and forwardRef components can receive refs and automatically accept these props.
const Component = forwardRef(() => <div />); <Component ref={(current) => console.log(current)} />
You only need this type if you manually author the types of props that need to be compatible with legacy refs.
interface Props extends React.RefAttributes<HTMLDivElement> {} declare const Component: React.FunctionComponent<Props>;
Otherwise it's simpler to directly use Ref since you can safely use the props type to describe to props that a consumer can pass to the component as well as describing the props the implementation of a component "sees". RefAttributes is generally not safe to describe both consumer and seen props.
interface Props extends { ref?: React.Ref<HTMLDivElement> | undefined; } declare const Component: React.FunctionComponent<Props>;
WARNING: The implementation of a component will not have access to the same type in versions of React supporting string refs. The following example would be incorrect usage because Component would never have access to a ref with type string
const Component = (props: React.RefAttributes) => props.ref;

property ref

ref?: Ref<T> | undefined;

Allows getting a ref to the component instance. Once the component unmounts, React will set ref.current to null (or call the ref with null if you passed a callback ref).
See Also

interface RefObject

interface RefObject<T> {}

Created by createRef, or useRef when passed null.

T The type of the ref's value.

Example 1

const ref = createRef<HTMLDivElement>();

ref.current = document.createElement('div'); // Error

property current

interface ViewTransitionProps {}

property children

children?: ReactNode | undefined;

property className

className?: string | undefined;

Assigns the class to the underlying DOM node.

property enter

enter?: 'none' | (string & {}) | undefined;

Combined with className if this <ViewTransition> or its parent Component is mounted and there's no other with the same name being deleted. "none" is a special value that deactivates the view transition name under that condition.

property exit

exit?: 'none' | (string & {}) | undefined;

Combined with className if this <ViewTransition> or its parent Component is unmounted and there's no other with the same name being deleted. "none" is a special value that deactivates the view transition name under that condition.

property layout

layout?: 'none' | (string & {}) | undefined;

Combined with className there are no updates to the content inside this boundary itself but the boundary has resized or moved due to other changes to siblings. "none" is a special value that deactivates the view transition name under that condition.

property name

name?: 'auto' | (string & {}) | undefined;

"auto" will automatically assign a view-transition-name to the inner DOM node. That way you can add a View Transition to a Component without controlling its DOM nodes styling otherwise.
A difference between this and the browser's built-in view-transition-name: auto is that switching the DOM nodes within the <ViewTransition> component preserves the same name so this example cross-fades between the DOM nodes instead of causing an exit and enter. "auto"

property onEnter

onEnter?: (instance: ViewTransitionInstance) => void;

The <ViewTransition> or its parent Component is mounted and there's no other <ViewTransition> with the same name being deleted.

property onExit

onExit?: (instance: ViewTransitionInstance) => void;

The <ViewTransition> or its parent Component is unmounted and there's no other <ViewTransition> with the same name being deleted.

property onLayout

onLayout?: (instance: ViewTransitionInstance) => void;

There are no updates to the content inside this <ViewTransition> boundary itself but the boundary has resized or moved due to other changes to siblings.

property onShare

onShare?: (instance: ViewTransitionInstance) => void;

This <ViewTransition> is being mounted and another <ViewTransition> instance with the same name is being unmounted elsewhere.

property onUpdate

onUpdate?: (instance: ViewTransitionInstance) => void;

The content of <ViewTransition> has changed either due to DOM mutations or because an inner child <ViewTransition> has resized.

property ref

ref?: Ref<ViewTransitionInstance> | undefined;

share?: 'none' | (string & {}) | undefined;

Combined with className if this <ViewTransition> is being mounted and another instance with the same name is being unmounted elsewhere. "none" is a special value that deactivates the view transition name under that condition.

property update

update?: 'none' | (string & {}) | undefined;

Combined with className if the content of this <ViewTransition> has changed either due to DOM mutations or because an inner child has resized. "none" is a special value that deactivates the view transition name under that condition.

    : {};

Used to retrieve the props a component accepts. Can either be passed a string, indicating a DOM element (e.g. 'div', 'span', etc.) or the type of a React component.
It's usually better to use ComponentPropsWithRef or ComponentPropsWithoutRef instead of this type, as they let you be explicit about whether or not to include the ref prop.
Example 1
// Retrieves the props an 'input' element accepts type InputProps = React.ComponentProps<'input'>;
Example 2
const MyComponent = (props: { foo: number, bar: string }) => <div />; // Retrieves the props 'MyComponent' accepts type MyComponentProps = React.ComponentProps<typeof MyComponent>;
See Also

Example 1

// Retrieves the props an 'input' element accepts
type InputProps = React.ComponentPropsWithoutRef<'input'>;

Example 2

const MyComponent = (props: { foo: number, bar: string }) => <div />;

// Retrieves the props 'MyComponent' accepts

        ? PropsWithoutRef<Props> & RefAttributes<InstanceType<T>>
        : Props
    : ComponentProps<T>;

Used to retrieve the props a component accepts with its ref. Can either be passed a string, indicating a DOM element (e.g. 'div', 'span', etc.) or the type of a React component.

Example 1

// Retrieves the props an 'input' element accepts
type InputProps = React.ComponentPropsWithRef<'input'>;

Example 2

const MyComponent = (props: { foo: number, bar: string }) => <div />;

// Retrieves the props 'MyComponent' accepts
type MyComponentPropsWithRef = React.ComponentPropsWithRef<typeof MyComponent>;

type ComponentRef

type ComponentRef<T extends ElementType> =
    ComponentPropsWithRef<T> extends RefAttributes<infer Method> ? Method : never;

    <UserContext.Consumer>
      {user => <img src={user.profileImage} alt={user.name} />}
    </UserContext.Consumer>
  );
}

type ContextType

type ContextType<C extends Context<any>> = C extends Context<infer T> ? T : never;

Used to retrieve the type of a context object from a Context.

C The context object.

Example 1

import { createContext } from 'react';

const MyContext = createContext({ foo: 'bar' });

type ContextType = ContextType<typeof MyContext>;
// ContextType = { foo: string }

type CustomComponentPropsWithRef

type CustomComponentPropsWithRef<T extends ComponentType> =
    T extends JSXElementConstructor<infer Props>
        ? // If it's a class i.e. newable we're dealing with a class component
          T extends abstract new (args: any) => any
            ? PropsWithoutRef<Props> & RefAttributes<InstanceType<T>>
            : Props
        : never;

Used to retrieve the props a custom component accepts with its ref.
Unlike ComponentPropsWithRef, this only works with custom components, i.e. components you define yourself. This is to improve type-checking performance.

    | ComponentType<P>;

Used to retrieve the possible components which accept a given set of props.
Can be passed no type parameters to get a union of all possible components and tags.
Is a superset of ComponentType.
P The props to match against. If not passed, defaults to any. Tag An optional tag to match against. If not passed, attempts to match against all possible tags.
Example 1

type PropsWithChildren

type PropsWithChildren<P = unknown> = P & { children?: ReactNode | undefined };

type PropsWithoutRef

type PropsWithoutRef<Props> =
    // Omit would not be sufficient for this. We'd like to avoid unnecessary mapping and need a distributive conditional to support unions.
    // see: https://www.typescriptlang.org/docs/handbook/2/conditional-types.html#distributive-conditional-types
    // https://github.com/Microsoft/TypeScript/issues/28339
    Props extends any
        ? 'ref' extends keyof Props
            ? Omit<Props, 'ref'>
            : Props
        : Props;

Omits the 'ref' attribute from the given props object.
Props The props object type.

type PropsWithRef

type PropsWithRef<Props> = Props;

Ensures that the props do not include string ref, which cannot be forwarded
Deprecated
Use Props directly. PropsWithRef<Props> is just an alias for Props

type Provider

type Provider<T> = ProviderExoticComponent<ProviderProps<T>>;

Wraps your components to specify the value of this context for all components inside.

Example 1

import { createContext } from 'react';

const ThemeContext = createContext('light');

function App() {
  return (
    <ThemeContext.Provider value="dark">
      <Toolbar />
    </ThemeContext.Provider>
  );
}

type ReactEventHandler

    | string
    | number
    | bigint
    | Iterable<ReactNode>

    | null
    | undefined
    | DO_NOT_USE_OR_YOU_WILL_BE_FIRED_EXPERIMENTAL_REACT_NODES[keyof DO_NOT_USE_OR_YOU_WILL_BE_FIRED_EXPERIMENTAL_REACT_NODES]
    | Promise<AwaitedReactNode>;

Represents all of the things React can render.

Where ReactElement only represents JSX, ReactNode represents everything that can be rendered.

Example 1

// Typing children
type Props = { children: ReactNode }

const Component = ({ children }: Props) => <div>{children}</div>

<Component>hello</Component>

Example 2

// Typing a custom element
type Props = { customElement: ReactNode }

const Component = ({ customElement }: Props) => <div>{customElement}</div>

<Component customElement={<div>hello</div>} />

type Reducer

type Reducer<S, A> = (prevState: S, action: A) => S;

    ? S
    : never;

type ReducerWithoutAction

type ReducerWithoutAction<S> = (prevState: S) => S;

type Ref

type Ref<T> = RefCallback<T> | RefObject<T | null> | null;

A union type of all possible shapes for React refs.

- RefCallback
- RefObject

type RefCallback

type RefCallback<T> = {
    bivarianceHack(
        instance: T | null
    ):
        | void
        | (() => VoidOrUndefinedOnly)
        | DO_NOT_USE_OR_YOU_WILL_BE_FIRED_CALLBACK_REF_RETURN_VALUES[keyof DO_NOT_USE_OR_YOU_WILL_BE_FIRED_CALLBACK_REF_RETURN_VALUES];
}['bivarianceHack'];

A callback fired whenever the ref's value changes.
T The type of the ref's value.
Example 1
<div ref={(node) => console.log(node)} />

type Reference

type Reference = object;

type SetStateAction

type SetStateAction<S> = S | ((prevState: S) => S);

The instruction passed to a Dispatch function in useState to tell React what the next value of the useState should be.

Often found wrapped in Dispatch.

S The type of the state.

Example 1

// This return type correctly represents the type of
// `setCount` in the example below.
const useCustomState = (): Dispatch<SetStateAction<number>> => {
  const [count, setCount] = useState(0);

  return setCount;
}
