Methods

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 getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

Returns

void

Deprecated

16.3, use componentDidMount or the constructor instead

See

Inherited from

PureComponent.UNSAFE_componentWillMount

Defined in

node_modules/@types/react/index.d.ts:730


UNSAFE_componentWillReceiveProps

Optional UNSAFE_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.

This method will not stop working in React 17.

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

Parameters

NameType
nextPropsReadonly<P>
nextContextany

Returns

void

Deprecated

16.3, use static getDerivedStateFromProps instead

See

Inherited from

PureComponent.UNSAFE_componentWillReceiveProps

Defined in

node_modules/@types/react/index.d.ts:762


UNSAFE_componentWillUpdate

Optional UNSAFE_componentWillUpdate(nextProps, nextState, nextContext): void

Called immediately before rendering when new props or state is received. Not called for the initial render.

Note: You cannot call Component#setState here.

This method will not stop working in React 17.

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

Parameters

NameType

Returns

void

Inherited from

PureComponent.componentDidCatch

componentDidUpdate

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

shouldComponentUpdate

Optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean
