app.get("/:project", function(req, res, next){
db.loadProject(req.params.project, function(err, project){
if(err) return next(new HttpError.InternalServerError("Something went wrong"));
if(!project) return next(new HttpError.notFound("This project does not exist"));
res.json(project.toObject());
});
});
// in your error handler:
app.use(function(err, req, res, next){
res.status(err.code).json({ error: err.message });
