How to find the size of the file in Node.js?

To get a file’s size in megabytes:

var fs = require("fs"); // Load the filesystem module
var stats = fs.statSync("myfile.txt")
var fileSizeInBytes = stats.size;
// Convert the file size to megabytes (optional)
var fileSizeInMegabytes = fileSizeInBytes / (1024*1024);

or in bytes:

function getFilesizeInBytes(filename) {
    var stats = fs.statSync(filename);
    var fileSizeInBytes = stats.size;
    return fileSizeInBytes;
}
