Properties

context: unknown

If using React 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.

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>
props: Readonly<MessageViewProps>
state: Readonly<{}>
contextType?: Context<any>

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

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}</>;
}
}
propTypes?: any

Ignored by React.

Only kept in types for backwards compatibility. Will be removed in a future major release.

Methods

  • 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<MessageViewProps>
    • prevState: Readonly<{}>
    • Optionalsnapshot: any

    Returns 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

  • Parameters

    • Optionalcallback: () => 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

    Returns any

  • Type Parameters

    • K extends never

    Parameters

    • state:
          | null
          | {}
          | (
              prevState: Readonly<{}>,
              props: Readonly<MessageViewProps>,
          ) => null | {} | Pick<{}, K>
          | Pick<{}, K>
    • Optionalcallback: () => 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

    Returns boolean
