Searching files in dir with Node.js

Question

I'm currently trying to search for a few files in a specific folder on Windows using node and grunt.

I have a grunt task that has a function to read a dir with JSON files, but the problem is that when I run the task, the code to read the file doesn't do anything, everything else on that grunt task runs perfect, but that. I'm not sure if the reference for the path is correct, but I'm also using path.normalize() and it does not throws any error.

This is snippet of the code:

..// Some other code
var fs = require('fs'),
path = require("path");

grunt.registerTask('separate', function() {
var filePath = path.normalize("C:\Users\jbernhardt\Desktop\testkeeper\jenkinsReports");

fs.readdir(filePath, function(err, filenames) {

  //This log doesn't show as it the function is not running
  grunt.log.writeln("Testing");

    if (err) {
        grunt.log.writeln("Error");
        return;
    }
    filenames.forEach(function(filename){
        grunt.log.writeln("Testing");

    });

  });
...//Some more code below for the same task
}

Does anyone has an idea why this snippet of the code is being skipped when I run the task? I could probably be missing some basic stuffs. Thanks!

your forward slashes are escaping your path name

Use "C:\\Users\\..." or "C:/Users/"

Try readdirSync and check if your function still not working. I guess your process is finished before the callback.

Seems that you are correct, I tried that and its working!, I'll see for an alternative to read Async for best practice.

You can simply use the __dirname object to get the path where the current script is running:

..// Some other code
var fs = require('fs'),
path = require("path");

grunt.registerTask('separate', function() {

fs.readdir(__dirname, function(err, filenames) {

  //This log doesn't show as it the function is not running
  grunt.log.writeln("Testing");

    if (err) {
        grunt.log.writeln("Error");
        return;
    }
    filenames.forEach(function(filename){
        grunt.log.writeln("Testing");

    });

  });
...//Some more code below for the same task
}

You can find more info here.

you need change your path

var filePath = path.normalize("C:\\Users\\jbernhardt\\Desktop\\testkeeper\\jenkinsReports");

Also To achieve consistent results when working with Windows file paths on any operating system, use path.win32:

path.win32.basename('C:\\Users\\jbernhardt\\Desktop\\testkeeper\\jenkinsReports"');

The slash in path are being escaped.

"C:\\Users\\jbernhardt\\Desktop\\testkeeper\\jenkinsReports"

should solve your issue.
