> Check if a path exists |
|
|
|
NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed. |
|
|
|
While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it. |
|
|
|
Never use this before handling a file though: |
|
|
|
> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there. |
