reload: reload.js is not found

the reload isn’t working for me, and on checking direct access to the JS URL, the file isn’t being served.

http://localhost:4040/reload/reload.js

I added the file itself directly to my own pubilc/js dir and now things work fine.

any idea why the JS file isn’t automagically being served?

I’m using a vanilla express app setup with the generator so it’s quite confusing.

  debug('using hot reloader');
  var http = require('http');
  var reloadServer = http.createServer(app);
  let delay = 300;
  reload(reloadServer, app, delay);
  reloadServer.listen(app.get('port'), function() {
    console.log("Reload server listening on port " + app.get('port'));
  });

this block ^ also prints out the right port #

confused!
