Question

I have 2 js files in my node.js app

File a defines global object foo

In file b I can refer to foo.

But if file b is loaded before file a, then an error occurs.

I’m using node’s fs module to read the files. I use readdir, and then forEach require on every file. On my system the files are always read alphabetically, so there is never any problem.

Can I depend on those files being read alphabetically?

You can sort your array of files by name instead to be sure.

fs.readdir(path, function(err, files) {
    files.sort(function(a, b) {
        return a < b ? -1 : 1;
    }).forEach(function(file, key) {
        // stuff
    });
});
