title: 'Experimental `appDir: true`'

## Why This Error Occurred
|
|
|
|
Your project contains a directory named `app/`. Since Next.js 13, this is a [reserved name](/blog/next-13#new-app-directory-beta).
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
To use the new app directory and its features, please add `appDir: true` to your configuration in `next.config.js` under `experimental`.
|
|
|
|
```js filename="next.config.js"
|
|
/** @type {import('next').NextConfig} */
|
|
const nextConfig = {
|
|
experimental: {
|
|
appDir: true,
|
|
},
|
|
}
|
|
|
|
module.exports = nextConfig
|
|
```
|
|
|
|
If you do not want to use the new `app/` directory features yet, but have a directory named `app/`, rename the directory to something else.
