Using require without export

Question

I have this code (which works perfectly well) which I\'ve borrowed from an online resource:

var express = require(\'express\');
var bodyParser = require(\'body-p         


        

Answer 1

When you call require the module is loaded and executed. So you have a connected mongoose. Actually require makes a function that your entire module code injected there and finally run.

Now, if you want to reuse variables created in modules you should export that. Like :

//cache.js
var redis  = require("redis");

var redisClient  = redis.createClient(process.env.CACHE_PORT, process.env.CACHE_URL);
redisClient.auth(process.env.CACHE_PASS);

redisClient.on("ready", function () {
  console.log("Cache is connected");
});

module.exports = redisClient;
