Properties#

context#

• 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>

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 - https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#initializing-state - https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path

Returns#

void

Inherited from#

React.Component.UNSAFE_componentWillMount

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

Parameters#

Name	Type
`nextProps`	`Readonly`<`SpinnerProps`>
`nextContext`	`any`

void

Inherited from#

React.Component.UNSAFE_componentWillReceiveProps

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.

Returns#

void

Inherited from#

React.Component.UNSAFE_componentWillUpdate

componentDidCatch#

▸ Optional componentDidCatch(error, errorInfo): void

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

Parameters#

Name	Type
`error`	`Error`
`errorInfo`	`ErrorInfo`

Returns#

void

Inherited from#

React.Component.componentDidCatch

componentDidMount#

▸ Optional componentDidMount(): void

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

Returns#

void

Inherited from#

React.Component.componentDidMount

componentDidUpdate#

▸ Optional componentDidUpdate(prevProps, prevState, snapshot?): void

Called immediately after updating occurs. Not called for the initial render.

The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

componentWillMount#

▸ Optional componentWillMount(): void

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

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

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

componentWillReceiveProps#

▸ Optional componentWillReceiveProps(nextProps, nextContext): void

componentWillUnmount#

▸ Optional componentWillUnmount(): 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

componentWillUpdate#

▸ Optional componentWillUpdate(nextProps, nextState, nextContext): void

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

Parameters#

Name	Type

forceUpdate#

▸ forceUpdate(callback?): void

Parameters#

Name	Type
`callback?`	() => `void`

Returns#

void

Inherited from#

React.Component.forceUpdate

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#

Name	Type
`prevProps`	`Readonly`<`SpinnerProps`>
`prevState`	`Readonly`<{}>

Returns#

any

Inherited from#

React.Component.getSnapshotBeforeUpdate

render#

▸ render(): Element

Returns#

Element

Overrides#

React.Component.render

setState#

▸ setState<K>(state, callback?): void

Type parameters#

Name	Type
`K`	extends `never`

Parameters#

Name	Type
`state`	`null` \| {} \| (`prevState`: `Readonly`<{}>, `props`: `Readonly`<`SpinnerProps`>) => `null` \| {} \| `Pick`<{}, `K`> \| `Pick`<{}, `K`>
`callback?`	() => `void`

Returns#

void

Inherited from#

React.Component.setState

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#

Name	Type
`nextProps`	`Readonly`<`SpinnerProps`>
`nextState`	`Readonly`<{}>
`nextContext`	`any`

Returns#

boolean

React.Component.shouldComponentUpdate
