MongoDB URL

The MongoDB URL module exports a singleton object that helps getting a MongoDB URL based on some premises.

Get a MongoDB URL connection

This will return the a MongoDB URL connection based on options object.

Quick Start

Consider set a MONGODB_SERVER environment variable and assign to it:

• The MongoDB server:port
• The MongoDB replicaset server1:port1,server2:port2,server3:port3,server4:port4

$ npm i @felipecrescencio/mongodburl
$ export MONGODB_SERVER=10.0.0.1:27017,10.0.0.2:27017

Use mongodburl in your code:

var mongourl = require('@felipecrescencio/mongodburl');

console.log("Default: "+ mongourl.getUrl());
// Output: Default: mongodb://10.0.0.1:27017,10.0.0.2:27017/
console.log("User/pass params: "+ mongourl.getUrl({username: "user", password: "pass"}));
// Output: User/pass params: mongodb://user:pass@10.0.0.1:27017,10.0.0.2:27017/
console.log("Other params: "+ mongourl.getUrl({database: "customers", replicaset: "rs46", socketTimeoutMS: 600000}));
// Output: Other params: mongodb://10.0.0.1:27017,10.0.0.2:27017/customers?replicaSet=rs46&socketTimeoutMS=600000
mongodb.connect(mongourl);
//...

Without MONGODB_SERVER environment variable

If no MONGODB_SERVER environment variable was assigned, it will return the default value localhost:27017.

$ npm i @felipecrescencio/mongodburl

In your code:

var mongourl = require('@felipecrescencio/mongodburl');

console.log("Default: "+ mongourl.getUrl());
// Output: Default: mongodb://localhost:27017/
console.log("User/pass params: "+ mongourl.getUrl({username: "user", password: "pass"}));
// Output: User/pass params: mongodb://user:pass@localhost:27017/
console.log("Other params: "+ mongourl.getUrl({database: "customers", replicaset: "rs46", socketTimeoutMS: 600000}));
// Output: Other params: mongodb://localhost:27017/customers?replicaSet=rs46&socketTimeoutMS=600000
mongodb.connect(mongourl);
//...
