How to use the useContext React hook

Find out what the useContext React hook is useful for, and how to work with it!

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.
