Properties

Property	Modifier	Type	Description	Overrides	Inherited from
contextType?	static	Context<any>	If set, this.context will be set at runtime to the current value of the given Context. Example 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}</>; } } See https://react.dev/reference/react/Component#static-contexttype	-	Component.contextType
context	public	unknown	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 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 React Docs	-	Component.context

Methods

setState()

setState<K>(state, callback?): void

Type Parameters

Type Parameter
K extends keyof State

Parameters

Parameter	Type
state	null | State | (prevState, props) => null | State | Pick<State, K> | Pick<State, K>
callback?	() => void

Returns

void

Inherited from

Component.setState

---

forceUpdate()

forceUpdate(callback?): void

Parameters

Parameter	Type
callback?	() => void

Returns

void

Inherited from

Component.forceUpdate

---

componentDidMount()?

optional componentDidMount(): void

Called immediately after a component is mounted. Setting state here will trigger re-rendering.

Returns

void

Inherited from

Component.componentDidMount

---

shouldComponentUpdate()?

optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

Called to determine whether the change in props and state should trigger a re-render.

Component always returns true. PureComponent implements a shallow comparison on props and state and returns true if any props or states have changed.

If false is returned, Component.render, componentWillUpdate and componentDidUpdate will not be called.

Parameters

Parameter	Type
nextProps	Readonly<Props>
nextState	Readonly<State>
nextContext	any

Returns

boolean

Inherited from

Component.shouldComponentUpdate

---

componentWillUnmount()?

optional componentWillUnmount(): void

Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as cancelled network requests, or cleaning up any DOM elements created in componentDidMount.

Returns

void

Inherited from

Component.componentWillUnmount

---

getSnapshotBeforeUpdate()?

optional getSnapshotBeforeUpdate(prevProps, prevState): any

Runs before React applies the result of Component.render render to the document, and returns an object to be given to componentDidUpdate. Useful for saving things such as scroll position before Component.render render causes changes to it.

Note: the presence of this method prevents any of the deprecated lifecycle events from running.

Parameters

Parameter	Type
prevProps	Readonly<Props>
prevState	Readonly<State>

Returns

any

Inherited from

Component.getSnapshotBeforeUpdate

---

componentDidUpdate()?

optional componentDidUpdate(prevProps, prevState, snapshot?): void

Called immediately after updating occurs. Not called for the initial render.

The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Parameters

Parameter	Type
prevProps	Readonly<Props>
prevState	Readonly<State>
snapshot?	any

Returns

void

Inherited from

Component.componentDidUpdate

---

componentWillMount()?

optional componentWillMount(): void

Called immediately before mounting occurs, and before Component.render. Avoid introducing any side-effects or subscriptions in this method.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Returns

void

Deprecated

16.3, use ComponentLifecycle.componentDidMount componentDidMount or the constructor instead; will stop working in React 17

---

UNSAFE_componentWillMount()?

optional UNSAFE_componentWillMount(): void

Called immediately before mounting occurs, and before Component.render. Avoid introducing any side-effects or subscriptions in this method.

This method will not stop working in React 17.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Returns

void

Deprecated

16.3, use ComponentLifecycle.componentDidMount componentDidMount or the constructor instead

Inherited from

Component.UNSAFE_componentWillMount

---

componentWillReceiveProps()?

optional componentWillReceiveProps(nextProps, nextContext): void

Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

Calling Component.setState generally does not trigger this method.

Note: the presence of NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Parameters

Parameter	Type
nextProps	Readonly<Props>
nextContext	any

Returns

void

Deprecated

UNSAFE_componentWillReceiveProps()?

optional UNSAFE_componentWillReceiveProps(nextProps, nextContext): void
