Use fs to check if something in another folder exists in node.js

Question

Folder1
- file1.js
Folder2
- file2.js

I want to check if file2.js exists, from file1.js using fs (they're in different folders)

I haven't been able to find a way I can do this, without listing the whole directory of file2.js.

Does anyone know the best way to achieve this?

Use fs.existsSync:

In you file1.js

if (fs.existsSync(__dirname + '/../Folder2/file2.js')) {
    console.log('Found file');
}

__dirname + '../Folder2/file2.js' gives me directory/folder1../folder2/file2.js. I need it to give me directory/folder2/file2.js instead

Updated my answer missed a slash before ../. You can't directly get to that directory but you can check relative to your own directory that is relative to file1.js

I do not agree file path use string + string. There is a way that use path.join is more safe and more right than string and more information can see here.
