Handle any error Nodejs and don't return a stack trace

Question

The question is simple, but I cannot find a solution that will work when tested against Passport.

Let's say I have a callback route like https://localhost/auth/google/callback

Right now I'm getting a stack trace if I throw garbage parameters here that then shows information like directory structures, etc, which is obviously not appropriate. I cannot blindly depend on every new route to handle errors appropriately.

Is there any way for me to disable a stack trace response given ANY error in NodeJS?

I tried the following:

app.use((err, req, res, next) => { 
    if (! err) {
        return next();
    }    

    res.status(500);
    res.send('500: Internal server error');
});

And this did not work for TokenError: Code was already redeemed. used in PassportJS.

Is this even possible? Obviously this would be for a production environment only.

You need to set NODE_ENV to production to disable stacktrace, you can change it as an enviroment variable.

set NODE_ENV=production

Or if it's inconvenient do it in the program itself like this:

process.env.NODE_ENV = 'production';
