如何将此代码放在外部文件中？

Question

I've made a little chat with nodeJS, now i want to put this part of code https://github.com/P-Pariston/nodeChat/blob/698ced0afc77e359a2bd32618baf66a873241816/app.js#L112-402 (in yellow) in an external file called commands.js.

Actually, i've tested this:

app.js

Command.prototype.parser = require('./commands.js');

commands.js

module.export = function (){...}

It doesn't work, i have:

"MongoClient is not defined".

All modules are not passed in commands.js as i can see (socket.io)

Thanks for your help !

Answer 1

It doesn't include the context for MongoClient which has been set with a require at the top of the first set of code (outside the commands file)

MongoClient = require('mongodb').MongoClient,
