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 () {

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

see 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

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.
