MongoPooler

NodeJS package to manage MongoDB connections

Installation

To install this package, navigate to your project root and run:
npm install --save mongopooler

Usage

Import the pooler wherever it needs to be used
let MongoPool = require('mongopooler');

Setup the pool in your main server file

var options = { numberOfRetries : 5, auto_reconnect: true, poolSize : 40, connectTimeoutMS: 500 };
var uri = "mongoURI"
MongoPool.createPool(uri, options);

Access the pool from wherever required, to make calls to your MongoDB

MongoPool.getInstance(function(client){
  // Perform DB operations here
})

Notes:

• The getInstance function returns a MongoDB client object, you still have to call client.db on it to pick a database
  
• getInstance will fail if it's called before createPool() is
  

Misc

This package is inspired by Yaki Klein's answer on this StackOverflow post.
