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()
```
