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}</>;
}
}

UNSAFE_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.
16.3, use componentDidMount or the constructor instead
Optional
UNSAFE_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.
16.3, use static getDerivedStateFromProps instead
Optional
UNSAFE_Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState
here.

Optional
componentOptional
componentCalled immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Optional
getRuns 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.

If using the new style context, re-declare this in your class to be the

of yourstatic contextType
. Should be used with type annotation or static contextType.
