Conduct of Code

I see you lack a style guide.

```
if(process.env.NODE_ENV !== 'production') {
    res.write(err.message + " " + err.stack);
}
```

OR

```
if (path.includes("..") || path.includes("~")) return res.status(503).end("Y U HAX >:( ")
```

OR

```
if (req.path === '/')
    path = '/index.js';
```

???
