    Constructors

    • Type Parameters

      • P = {}
      • S = {}
      • SS = any

      Parameters

      • props: P

      Returns Component<P, S, SS>

    • Type Parameters

      • P = {}
      • S = {}
      • SS = any

      Parameters

      • props: P
      • context: any

      Returns Component<P, S, SS>

    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.

    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<P>
    refs: { [key: string]: ReactInstance }
    state: Readonly<S>
    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}</>;
    }
    }

    Methods

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

      Parameters

      Returns void

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

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

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

      Parameters

      Returns null | SS

    • Returns ReactNode

    • Type Parameters

      • K extends string | number | symbol

      Parameters

      • state:
            | null
            | S
            | ((prevState: Readonly<S>, props: Readonly<P>) => null | S | Pick<S, K>)
            | Pick<S, 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
