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​

PureComponent.UNSAFE_componentWillMount

Defined in​

node_modules/@types/react/index.d.ts:688

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

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.

cssClasses​

▸ cssClasses(classRules, includeComponentClassName?): string

Generate a string of CSS classes from the properties of the passed-in object that resolve to true.

           'my-class-modifier': this.props.modifier
       }, true);

fire​

▸ fire(eventName, target, data?): void

Creates and sends a new IMA.js DOM custom event from this component.

any

shouldComponentUpdate​

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

Called to determine whether the change in props and state should trigger a re-render.
