javascript - Node: required module not in scope of function inside module.exports? -

i'm having scoping issue seem unable elegantly solve.

scenario

the top of file has module required in next way

var moment = require('moment-timezone');

what attempting do, take function saved json string , convert function (using json-fn). below require have like:

module.exports = function() { //job[1] json hash holding function. more on in below text. var func = jsonfn.parse(job[1]) func() };

in case of function has no need of file's modules, can invoke function , works perfectly. however, when seek invoke function using moment module, below error:

error referenceerror: moment not defined @ eval

despite best efforts, cannot seem 'moment' variable function's scope. works if alter module's require statement to:

global.moment = require('moment-timezone');

i have tried multiple different modules, confirm wasn't specific moment, , no module have tested has worked.

question

is scoping module global object appropriate way prepare problem? or there other method of attaching function right scope?

thanks in advance help , looking forwards reading suggestions!
