async exits with streamline

gistfile1.js

//this does not work because exists does not accept a standard callback

    function createRequiredFilesIfNotPresent(_) {
        var baseFolder = process.cwd();
        var exists = path.exists(baseFolder + "/server.js");
        log.info(exists);
    }


//using a wrapper function however works. Log entries added for sequence.

    function exists(p, callback) {
        path.exists(p, function(e) {
            callback(null, e);
        });
    }

    function createRequiredFilesIfNotPresent(_) {
        var baseFolder = process.cwd();
        log.info("check exists start");
        var p1 = exists(baseFolder + "/server.js", _);
        log.info("exists:" + p1);
        log.info("check exists complete");
    }

Sure. My skype is offline most of the time but I'll turn it on. But that won't be before tomorrow as I'm travelling today.

Forgot. my skype id is bjouhier
