Properties

context

context: unknown

Defined in: node_modules/@types/react/index.d.ts:955

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.

Example

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>

static optional contextType?: Context\<any>

Defined in: node_modules/@types/react/index.d.ts:931

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

Example

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

componentDidCatch()

componentDidCatch(error, errorInfo): void

Defined in: src/components/error-boundary/ErrorBoundary.tsx:35

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

Parameters

error

Error

errorInfo

ErrorInfo

Returns

void

Overrides

Component.componentDidCatch

componentDidMount()?

optional componentDidMount(): void

Defined in: node_modules/@types/react/index.d.ts:1198

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

Returns

void

Inherited from

Component.componentDidMount

componentDidUpdate()?

optional componentDidUpdate(prevProps, prevState, snapshot?): void

Defined in: node_modules/@types/react/index.d.ts:1261

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\<P>

prevState

Readonly\<S>

snapshot?

any

Returns

void

Inherited from

Component.componentDidUpdate

~~componentWillMount()?~~

optional componentWillMount(): void

Defined in: node_modules/@types/react/index.d.ts:1277

Called immediately before mounting occurs, and before Component.render. Avoid introducing any side-effects or subscriptions in this method.

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

Returns

void

Deprecated

16.3, use ComponentLifecycle.componentDidMount componentDidMount or the constructor instead; will stop working in React 17

See

Inherited from

Component.componentWillMount

~~componentWillReceiveProps()?~~

optional componentWillReceiveProps(nextProps, nextContext): void

Defined in: node_modules/@types/react/index.d.ts:1308

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.

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

Parameters

nextProps

Readonly\<P>

nextContext

any

Returns

void

Deprecated

16.3, use static StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps instead; will stop working in React 17

Component.componentWillReceiveProps

componentWillUnmount()?

optional componentWillUnmount(): void

Defined in: node_modules/@types/react/index.d.ts:1214

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

Inherited from

Component.componentWillUnmount

~~componentWillUpdate()?~~

optional componentWillUpdate(nextProps, nextState, nextContext): void

Defined in: node_modules/@types/react/index.d.ts:1340

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

Note: You cannot call Component.setState here.

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

Parameters

nextProps

Readonly\<P>

nextState

Readonly\<S>

nextContext

any

Returns

Returns

Inherited from

Component.forceUpdate

getSnapshotBeforeUpdate()?

optional getSnapshotBeforeUpdate(prevProps, prevState): any

Defined in: node_modules/@types/react/index.d.ts:1255

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

prevProps

Readonly\<P>

prevState

Readonly\<S>

Returns

any

render()

render(): ReactNode

Defined in: src/components/error-boundary/ErrorBoundary.tsx:43

Returns

Overrides

setState()

setState\<K>(state, callback?): void

Defined in: node_modules/@types/react/index.d.ts:971

Type Parameters

K

Parameters

callback?

() => void

Returns

void

Component.setState

shouldComponentUpdate()?

optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

Defined in: node_modules/@types/react/index.d.ts:1209

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

nextProps

Readonly\<P>

nextState

Readonly\<S>

nextContext

any

Returns

boolean

~~UNSAFE_componentWillMount()?~~

optional UNSAFE_componentWillMount(): void

Defined in: node_modules/@types/react/index.d.ts:1292

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 NewLifecycle.getSnapshotBeforeUpdate getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.
