simple-mongodb

A simple lib to simplify your work of using mongoldb native driver in node.js.

Installation

npm install --save simple-mongodb

Usage

First, you should connect the mongodb when app starts:

import DB from 'simple-mongodb';

DB.connect(url);

The connect() method is asynchronous. It will return a Promise, so you can use it like:

DB.connect(url)
  .then(db => {
    // db is the instance of connected database.
  })
  .catch(err => console.log(err));

or:

async function() {
  try {
    const db = await DB.connect(url);    
  } catch (err) {
    console.log(err);
  }
}

Once the mongodb is connected, you could use it anywhere in your code like this:

DB.find(collectionName, args);

The args is an object whose propertoes arr correspond to the MongoDB Driver's arguments.

Methods
