    • props: Props

    Returns CopyToClipboard

Properties

context: 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

notificationTimeout: number
props: Readonly<Props>
refs: {
    [key: string]: ReactInstance;
}

Type declaration

  • [key: string]: ReactInstance

Deprecated

See

Legacy React Docs

state: Readonly<State>
timeoutRef: any
contextType?: 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}</>;
}
}

Methods

  • 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 NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

    Parameters

    • nextProps: Readonly<Props>
    • nextContext: any

    Returns void

  • Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.

    Parameters

    • error: Error
    • errorInfo: ErrorInfo

    Returns void

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

    Returns 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

    • prevProps: Readonly<Props>
    • prevState: Readonly<State>
    • Optional snapshot: any

    Returns 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

    • nextProps: Readonly<Props>
    • nextContext: any

    Returns void

    Deprecated

    16.3, use static StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps instead; will stop working in React 17

  • Parameters

    • Optional callback: (() => void)
        • (): void
        • Returns void

    Returns void

  • 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

    • prevProps: Readonly<Props>
    • prevState: Readonly<State>

    Returns any

  • Returns Element

  • Type Parameters

    • K extends "isShowing"

    Parameters

    • state: State | ((prevState, props) => State | Pick<State, K>) | Pick<State, K>
    • Optional callback: (() => void)
        • (): void
        • Returns void

    Returns void

  • 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

    • nextProps: Readonly<Props>
    • nextState: Readonly<State>
    • nextContext: any

    Returns boolean
