nodejs in windows file system path error 4058 ENOENT

I am using file system with nodejs in windows to write process logs. I have follwing code

var fs = require('fs');
var config = JSON.parse(fs.readFileSync('config.json', 'utf8'));
var statusLogStream = fs.createWriteStream("../logs/load stat"+(new Date())+".log");

It turns out with an error 

    { [Error: ENOENT: no such file or directory, open 'C:\proc\logs\load stat Mon Apr 18 2016 19:09:32 GMT+0530 (India Standard Time).log']
  errno: -4058,
  code: 'ENOENT',
  syscall: 'open',
  path: 'C:\\proc\\logs\\load stat Mon Apr 18 2016 19:09:32 GMT+0530 (India Standard Time).log' }
events.js:141
      throw er; // Unhandled 'error' event
  ^

I try the folder to open the file manually C:\\proc\\logs it doesn't work and C:/proc/logs this when I replace double backward slash by forward slash I can manually open the folder from explorer.

How to make it working

Why is it taking the double backward slash instead of forward slash

IMP: The above code works perfectly fine in linux ubuntu server but not in windows

I had the same issue.

In my project when I ran an express app I noticed that the current working directory was the root directory of the project (while I was trying to read a file that was located in the script's directory). It could not run the file since process.cwd() !== __dirname.

You can check it out and console log process.cwd() in the script you are trying to read the json file.

I just changed the the path to:

const fs = require('fs');
fs.readFileSync(`${__dirname}\\FILENAME`);

The problem is not about the slashes but on how the date is converted to string.

I bet this will work:

var statusLogStream = fs.createWriteStream("../logs/load stat.log");

Update Windows is complaining about the two colons in the string representation of date (Mon Apr 18 2016 19**:**09**:**32 GMT+0530 (India Standard Time))

This could be a good alternative:

var myDate = new Date().toJSON().replace(new RegExp(':', 'g'),'.');
// myDate is now "2016-04-18T15.19.21.174Z"
var statusLogStream = fs.createWriteStream("../logs/load stat"+(myDate)+".log");
