react-use-debug-hooks v1.0.3

Important!

Do NOT use in production environment!

This package is intended to be a debugging tool only! Therefore, it should be installed within the devDependancies and all usage removed from the codebase before pushing to a production environment.

useDebugInfo Reference

Parameter Explanation

• componentName: This changes the debug label outputted with the changed deps in the console.
• props: The props you want to observe for changes.
• logOnlyWhenPropsChange: If you want to display in console only when any prop changes.

Parameter Types

• effectConsoleName: string
• props: object
• logOnlyWhenPropsChange: boolean

useEffectDebugInfo Reference

Parameter Explanation

• effectConsoleName: This changes the debug label outputted with the changed deps in the console.
• effect: A callback function that contains imperative, possibly effectful code.
• deps: The effect will only activate if the values in the list change.

Parameter Types

• effectConsoleName: string
• effect: React.EffectCallback
• deps: React.DependencyList

Extra Details

• useDebugInfo just requires a componentName to be displayed in console and an object with all the props needed to be observed for changes.
• useDebugInfo has a final (optional) parameter logOnlyWhenPropsChange if you want displayed in the console only when anything changes and not every render.
• For useDebugInfo, besides which props have changed, the renderCount and renderTime is also displayed.
• useEffectDebugInfo also requires a effectConsoleName to be displayed in the console.
• useEffectDebugInfo's effect callback an deps list is no different from useEffect ones.

Example Usage

// ExampleComponent.tsx
import { useDebugInfo, useEffectDebugInfo } from 'react-use-debug-hooks';

const ExampleComponent = ({ title: string, initialCount = 0 }: ExampleComponentProps) => {
  const [ string, setString ] = useState('0');
  const count = useCount(initialCount);

  const debugInfo = useDebugInfo('ExampleComponent', { // provide all props that we want to observe for changes
    title,
    initialCount,
    string,
    count,
  }, true); // optional param 'logOnlyWhenPropsChange' to not be spammed in the console
            // when component renders too much without any of the observed props changing

  useEffectDebugInfo('reset_string_effect', () => {
    setString('0');
  }, [ initialCount ]); // only fires when useEffect hook's dependencies changes

  return (
    <>
      <h5>Title: {title}</h5>
      <p>String: {string}</p>
      <p>Render count: {count}</p>
      <button onClick={() => setString((prevS) => String(Number(prevS) + 1))}>Increment String</button>
    </>
  );
}
