Constructors

### constructor

- new CatchErrors(props): CatchErrors

- #### Parameters

  - props: any

  #### Returns CatchErrors

  Overrides React.Component<{ error?: any; onMounted?: (setError: (error?: any) => void) => void; errorRenderer?: (error: Error, reset: () => any) => React.ReactNode; reset?: () => any; children: any; },any>.constructor

  - Defined in work/deeplinks/deeplinks/imports/client-handler.tsx:17

##
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.

#### 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>

##
Methods

### `Optional` UNSAFE_componentWillMount

- 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 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

  #### See

  Inherited from React.Component.UNSAFE_componentWillMount

  - Defined in work/deeplinks/deeplinks/node_modules/@types/react/index.d.ts:1457

### `Optional` UNSAFE_componentWillReceiveProps

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

  #### Parameters

  - nextProps: Readonly<{
    children: any;
    error?: any;
    errorRenderer?: ((error: Error, reset: (() => any)) => ReactNode);
    onMounted?: ((setError: ((error?: any) => void)) => void);
    reset?: (() => any);
    }>
  - nextContext: any

  #### Returns void

  #### Deprecated

  16.3, use static StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps instead

### `Optional` getSnapshotBeforeUpdate

- getSnapshotBeforeUpdate(prevProps, prevState): any

- 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<{
    children: any;
    error?: any;
    errorRenderer?: ((error: Error, reset: (() => any)) => ReactNode);

### render

- render(): any

- #### Returns any

  Overrides React.Component.render

### `Optional` shouldComponentUpdate

- 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

  - nextProps: Readonly<{
    children: any;
    error?: any;
    errorRenderer?: ((error: Error, reset: (() => any)) => ReactNode);
    onMounted?: ((setError: ((error?: any) => void)) => void);
