fs-extra/docs/pathExists.md

fs-extra contains methods that aren't included in the vanilla Node.js fs package. Such as mkdir -p, cp -r, and rm -rf.

# pathExists(file[, callback])

Test whether or not the given path exists by checking with the file system. Like [`fs.exists`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback), but with a normal callback signature (err, exists). Uses `fs.access` under the hood.

- `file` `<String>`
- `callback` `<Function>`

## Example:

```js
const fs = require('fs-extra')

const file = '/tmp/this/path/does/not/exist/file.txt'
// Promise usage:
fs.pathExists(file)
  .then(exists => console.log(exists)) // => false
// Callback usage:
fs.pathExists(file, (err, exists) => {
  console.log(err) // => null
  console.log(exists) // => false
})
```
