Summary

• Consolidates functionality from Interval class into useInterval function
• Removes deprecated Interval class and all related files
• Fixes a bug where useInterval would not update setInterval's delay prop reactively

Migration

Users of useInterval should change how they use it:

// Before
const interval = useInterval(() => console.log('hi'), 1000);

// After
const interval = useInterval(1000, {
  callback: () => console.log('hi')
});

Users of Interval can migrate to useInterval with the callback option:

// Before
const interval = new Interval(1000, {
  callback: (count) => console.log(count)
});

// After
const interval = useInterval(1000, {
  callback: (count) => console.log(count)
});

All properties and methods (counter, isActive, pause(), resume(), reset()) are available on the return value.
