context: any

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>

Type declaration

  • [key: string]: ReactInstance
state: Readonly<{}>
contextType?: Context<any>

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

Usage:

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 getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

    • prevState: Readonly<{}>
    • 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.

  • 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

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

    Note: You cannot call Component#setState here.
