Properties​

context​

• 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>

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

See

Returns​

void

Inherited from​

Component.UNSAFE_componentWillMount

Defined in​

node_modules/@types/react/ts5.0/index.d.ts:735

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

UNSAFE_componentWillUpdate​

▸ Optional UNSAFE_componentWillUpdate(nextProps, nextState, nextContext): 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.

This method will not stop working in React 17.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

getSnapshotBeforeUpdate​

▸ Optional getSnapshotBeforeUpdate(prevProps, prevState): any

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 getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.

Parameters​

NameType
prevPropsReadonly<ErrorProps>
prevStateReadonly<ErrorAppState>

Returns​

any

render​

▸ render(): Element

Returns​

setState​

▸ setState<K>(state, callback?): void

NameType
Kextends keyof ErrorAppState

callback?() => void

Returns​

Inherited from​

Component.setState

Defined in​

node_modules/@types/react/ts5.0/index.d.ts:530

shouldComponentUpdate​

▸ Optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

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​

NameType
nextPropsReadonly<ErrorProps>
nextStateReadonly<ErrorAppState>
nextContextany

Returns​

boolean
