| title: createContext in a Server Component | |
| ## Why This Error Occurred | |
| You are using `createContext` in a Server Component but it only works in Client Components. | |
| ## Possible Ways to Fix It | |
| Mark the component using `createContext` as a Client Component by adding `'use client'` at the top of the file. | |
| ### Before | |
| ```jsx filename="app/example-component.js" | |
| import { createContext } from 'react' | |
| const Context = createContext() | |
| ``` | |
| ### After | |
| ```jsx filename="app/example-component.js" | |
| 'use client' | |
| import { createContext } from 'react' | |
| const Context = createContext() | |
| ``` | |
