How to write to a file using Nodejs?

Question

I am learning how to write to a file using Nodejs. I tried the below posted example, but I received the below posted error

How can I fix this error?

Code:

var fs = require('fs');

fs.writeFile("c://NodeTest", "Hey there!", function(err) {
if(err) {
    return console.log(err);
}

console.log("The file was saved!");
});

Error:

{ [Error: EPERM: operation not permitted, open 'c:\NodeTest']
errno: -4048,
code: 'EPERM',
syscall: 'open',
path: 'c:\\NodeTest' }

Since it looks like you are using windows, this seems to be a file permissions error. Try running your code as administrator (e.g. right click on the dos command prompt icon and choose "Run as administrator", then try to run your script).

Downvoter, care to explain? I just tried this on my box and it worked. – dcp Aug 17 '18 at 15:47
Not downvoter, but I think this is bad advice in general. "I'm unfamiliar" being met with "add sudo" or similar feels like a recipe for problems. – Fissure King Aug 17 '18 at 15:54
@Fissure King - Thanks for the feedback. I gave a windows specific answer because the OP used "c://" in the file path, which was a clear indicator they were on windows. Based on your feedback, however, I edited the answer to reflect that. – dcp Aug 17 '18 at 16:01

You don't have permission to access that file. Try running as administrator or manually changing the permissions on the file
