Class: Screenshot

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>

contextType

▪ Static Optional 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

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.

deprecated 16.3, use componentDidMount or the constructor instead

Inherited from

React.PureComponent.UNSAFE_componentWillMount

Defined in

node_modules/@types/react/index.d.ts:717

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.

deprecated 16.3, use static getDerivedStateFromProps instead
