File mime type in Node.js

Question

JavaScript

How to determine the mime type of a file in Node.js using standard modules?

I must say right away that I just started learning Node and I may not know the obvious things, but Google and the documentation did not help.

Answer 1

var execFile = require('child_process').execFile;
var filename = ...;
execFile('file',['-b','--mime-type',filename],function(error,stdout,stderr) {
    console.log("STDOUT:",stdout.trim());
});
