temp-dir 
Get the real path of the system temp directory
The os.tmpdir() built-in doesn't return the real path. That can cause problems when the returned path is a symlink, which is the case on macOS. Use this module to get the resolved path.
Install
$ npm install --save temp-dir
Usage
const tempDir = require('temp-dir');
console.log(tempDir);
//=> '/private/var/folders/3x/jf5977fn79jbglr7rk0tq4d00000gn/T'
console.log(require('os').tmpdir());
//=> '/var/folders/3x/jf5977fn79jbglr7rk0tq4d00000gn/T' // <= Symlink
