// This is an advanced example! It is not typically required for application code. | |
// If you are using a library like Redux or MobX, use the container component provided by that library. | |
// If you are authoring such a library, use the technique shown below. | |
// This example shows how to safely update subscriptions in response to props changes. | |
// In this case, it is important to wait until `componentDidUpdate` before removing a subscription. | |
// In the event that a render is cancelled before being committed, this will prevent us from unsubscribing prematurely. | |
// We also need to be careful about how we handle events that are dispatched in between | |
// `getDerivedStateFromProps` and `componentDidUpdate` so that we don't put stale values into the `state`. |
All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.
A number of methods in React are assumed to be "pure".
On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.
