How do I check if a file is executable in node.js?

Question

How do I check if a file is executable in node.js? Maybe something like ``` fs.isExecutable(function (isExecutable) { }) ```

Accepted Answer

You would use the `fs.stat` call for that.

The `fs.stat` call returns a fs.Stats object.

In that object is a `mode` attribute. The mode will tell you if the file is executable.

In my case, I created a file and did a `chmod 755 test_file` and then ran it through the following code:

```
var fs = require('fs');
test = fs.statSync('test_file');
console.log(test);
```

What I got for `test.mode` was 33261.

This link is helpful for converting `mode` back to unix file permissions equivalent.
