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>

Methods​
UNSAFE_componentWillMount​
â–¸ 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
see https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path
Returns​
void
Inherited from​
React.Component.UNSAFE_componentWillMount
Defined in​
node_modules/@types/react/index.d.ts:687
UNSAFE_componentWillReceiveProps​
â–¸ 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

getSnapshotBeforeUpdate​
â–¸ Optional getSnapshotBeforeUpdate(prevProps, prevState): any
Runs before React applies the result of render to the document, and

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.

shouldComponentUpdate​
â–¸ 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.

nextState | Readonly<{ hasError: boolean }> |
nextContext | any |
Returns​
boolean
