Node.js - check if path is file

In this article, we would like to show you how to check if path is a file using Node.js.

Quick solution:

const fs = require('fs');

const status = fs.lstatSync('/path/to/somewhere');

if (status.isFile()) {
    // ...
}

Warning:

When /path/to/somewhere is soft link and indicates to non-existing path, it is necessary to call fs.existsSync(/path/to/somewhere) before status checking.

Practical example

Projects structure:

Project/
  |
  +-- my_directory/
  |    |
  |    +-- my_file.json
  |
  +-- my_script.js

Example my_script.js file:

const fs = require('fs');

const isFile = (path) => {
    const status = fs.lstatSync(path);
    return status.isFile();
};


// Usage example:

console.log(isFile('my_directory'));              // false
console.log(isFile('my_directory/my_file.txt'));  // true
