如何在一个地方处理所有错误？

Question

I would like to know how I should handle my errors in one place using node.js

This is how I did:

First I create loggers/errors.js

And inside I have this object:

var Errors = {
 bad_request: 'Some error related with bad request'
};

Than, in other files I just require this file, and when some statement or some error can occur, i just call:

var Errors = require('../loggers/errors');

if (something here) {
 console.log(Errors.bad_request);
}

I would like to know if this is a good approach, if I am doing right, or if there is a module that already does what I want, but with extra features.

You could do something like this:

module.exports = {
    BadRequest: 'Request was bad',
    Timeout: 'Server timed out'
}

And require it in the main file

var Error = require ('../loggers/errors.js');

if(statement) {
    console.log (Error.BadRequest );
}

You need to declare module.exports or it won't be able to be required.
