Can I use hooks in class component?

You can’t use Hooks inside a class component, but you can definitely mix classes and function components with Hooks in a single tree. In the longer term, we expect Hooks to be the primary way people write React components.

How do you cache with react?

Enabling Render Caching

1. Step 1: Determine the correct caching state.
2. Step 2: Setup API calls.
3. Step 3: Cache locally in the unload handler.
4. Step 4: Restore the last known state on load.

You may also opt into managing the component’s local state with a reducer to make it more predictable.

How are hooks used in the Linter plugin?

The useSomething naming convention is how our linter plugin is able to find bugs in the code using Hooks. You can write custom Hooks that cover a wide range of use cases like form handling, animation, declarative subscriptions, timers, and probably many more we haven’t considered.
