The search query should be memoized, which means that if the user has previously searched for 'John' and the API has provided me valid results for that query, then next time when the user types 'Joh', there should be suggestion for the user with the previously memoized values(in this case 'John' would be suggested). It pushes us to connect more components directly to the store by supplying tons of React hooks. You can change its current property to store information and read it later. . In most cases, you shouldn't directly write to the cache, Update: As it is needed to load a library, it is better to persist it in the React Context, so it can be used in other components too: Context: import { ReactNode, useState } from 'react'; const ApiRegister = ({ children }: { children: ReactNode }) => { const [api Not based on React Router, so you can use it wherever you need to cache it.
