Purpose and use of showStackError in module /config/lib/express.js

[miller-productions]

Hi folks,

A query regarding a setting in module config/lib/express.js...

Inside the function initMiddleware there is the following call:

app.set('showStackError', true);

What is the intent behind this? I suspect it is related to whether or not to show full stack traces in the client response on error, however I am puzzled as to how/where this is used. I ask this question for the following reasons:

1. this setting doesn't appear to be used/read anywhere else in the app. i.e. a search here in the github repository for the setting showStackError returns only a single result, i.e. where it is set. I understand from this that it is probably not intended to be 'used' by the app but rather by the express module internally;
2. according to the express API doc, app.set(name, value) assigns setting name to value, where name is one of the properties from the app settings table. However, I note that showStackError isn't listed in said app settings table.

I must admit, I am still learning and understanding the meanjs project so please forgive me in advance if I have misunderstood something.

Thanks for your time reading and considering this question.

Sincerely,
Dan

@danoz-direct it's an old one indeed that doesn't exist anymore.
Can you submit a PR to remove both this one and the other jsonp option that you noted in the other issue?
