Check out my React hooks introduction first, if you’re new to them.
One React hook I sometimes use is useContext
.
import React, { useContext } from 'react'
This hook is used in combination with the React Context API.
In particular, this hook allows us to get the current context value:
const value = useContext(MyContext)
which refers to the nearest <MyContext.Provider>
component.
Calling useContext
will also make sure the component rerenders when the context value changes.
I recommend you to read my Context API tutorial to know more about it.
