What are the steps to reproduce this issue? Annotate a call with a tag in the OpenAPI definition. e.g. "- my-tag" Use a custom instance hook. Setup orval to use the custom instance on the specific tag. What happens? The import from useCallback is missing in those generated files. ...
Wrapping the function in useCallback() ensures the function is not recreated, so useEffect() is not triggered to run again. When to use useMemo() If a function includes a complex calculation, you can avoid recomputing it by using the useMemo() hook. This hook returns a memoized value ...
The second argument to the useCallback function is an empty array []. This means that the handleIncrement function will be memoized and will not change unless its dependencies change. Since we don’t have any dependencies here, it won’t change between renders. In the ChildComponent, we re...

This is a new function any time React's engine touches the <FidgetSpinner> component (calls the function). Whether it updates the DOM or not, calling the component re-defines this function with a new memory address. That causes a re-render of <Spinner>. const stableFunc = useCallback((...
At this time, we put this function inuseCallbackto return, because thedepsis empty, so there is no need to change it, so that when we click theincrease, we won't trigger the subcomponent'srender. How to check The dependency array (deps) will not be passed as a parameter to the cal...
UseCallback is used to optimize the rendering behavior of your React function components, while useMemo is used to memoize expensive functions to avoid having to call them on every render. As a standard construction of hooks, those two solutions are not so different. Like with useEffect, a hoo...

Why does this not work? We are usingmemo, so theTodoscomponent should not re-render since neither thetodosstate nor theaddTodofunction are changing when the count is incremented. This is because of something called "referential equality". ...
