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' }

Answer 1

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

Answer 2

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