DESCRIBESQuestion

CAUSED_BYRootCause

`use client` marks a component as client-rendered/interactive, but it does not prevent the component (and its subtree) from being rendered on the server for initial HTML; it mainly affects where React hooks like `useEffect` run and enables client-side hydration/interactivity.

const usePermissionsStoreAsync = hook(usePermissionsStore, /*suspense*/false); — const YourComponent = () => {. Tension: if (userPermissions.isLoading) { return Loading... ; } if (userPermissions.error) { return An error occurred ; }. Outcome: Try Leo Query. It handle's async data for Zustand.

If possible, try to keep it `undefined` instead of falling back to an empty array. — When `companyData` is `undefined`. Tension: This then gets into a `useMemo` dependency array, re-calculating everything. Outcome: Then, use optional chaining to work with it.

Mock axios.get and await the assertion with waitFor()

Create a memoized router context object from the app context and call `router.invalidate()` in a `useEffect` when that memoized object changes, so `beforeLoad`/`loader` rerun with the updated data.

I've tried the following to no avail: — import { useState, useEffect, useRef, memo, useMemo } from "react";.

Update the mongodb version and avoid using Mongoose in Next.js Edge Runtime; move the database access to a Node.js runtime

FIXED_BYSolution

Use React.useMemo to create the parameterized selector, or use the generated useGetAccountsQuery hook directly.

Move `useSQLiteContext` to the React component, obtain the SQLite DB instance there, and pass the DB instance (or data) into the thunk as an argument. Ensure the thunk action payload contains only serializable data.

FIXED_BYSolution

`useCallback` needs to be used — to be used as a callback and thus prevent the unnecessary re-renders. Tension: `memo` can't prevent `ExpensiveComponent` from being re-rendered. Outcome: const handleRender = useCallback(() => {...}, []);.

FIXED_BYSolution

You can separate the listItems to a new component and `useMemo` the url — const ListItem = ({ person, removeThis }) => {. Outcome: const ListItem = ({ person, removeThis }) => { const src = useMemo(() => { console.log(person.id, "this should not run on every loop");.

FIXED_BYSolution

Use an arrow function wrapper like () => { savedCallback.current() } when passing the interval callback
