    mongo-lazy

    Node-mongodb-native for lazy people. Don't ever open a collection again. Eat a piece of cake while doing parallel queries.
    All the methods of node-mongodb-native are available. See the official documentation.

    Installation

    npm install mongo-lazy
    

    Usage

    node --harmony yourScript.js
    

    The --harmony flag is necessary because we're using Harmony proxies to open and cache collections transparently.

    Example

      // Open a db w/ the 3 args of mongodb.Db(dbName, servConfig, options) or w/ 1 obj-arg like above
      var db = require('mongo-lazy').open({
        db: 'yummy',
        host: 'ds037987.mongolab.com',
        port: 37987,
        user: 'guest',
        password: '123456'
      });
     
      // No need to open collections anymore, just call them as you would usually do with the mongo CLI
      db.drink.findOne({name: 'Dom Perignon'}, function(err, domPerignon) {
        console.log('A good wine:\n', err || domPerignon, '\n');
      });
     
      // The 'findAll' method returns all the elements of a collection (equiv to find + toArray) 
      db.meal.findAll({from: 'France'}, function(err, frenchMeals) {
        console.log('French meals:\n', err || frenchMeals, '\n');
      });
     
      // Easy parallel queries: callback returns when all queries return or earlier if an error happened
      db([
        ['drink', 'findOne', {price: 'free'}],
        ['meal', 'findOne', {price: 'cheap'}],
        ['dessert', 'findAll', {quality: "good"}, {fields: {name: 1, _id: 0}}]
      ], function(err, drink, meal, desserts) {
        if (err) throw err;
        console.log('Drink:\n', drink);
        console.log('Meal:\n', meal);
        console.log('Desserts:\n', desserts, '\nBon appetit!\n');  
      });
     
      // Closing DB after 3 seconds
      setTimeout(function() {
        db.close();
      }, 3000);

    Using the underlying mongodb-native Db object

    The documentation of the mongodb-native Db object is here. To access and manipulate the underlying mongodb-native Db object, there are 3 hooks on the mongo-lazy db object:

    • db.close() to close the database
    • db.ready(listener) to attach a listener which will be fired when the mongodb-native Db is ready
    • db.$ which is the mongodb-native Db object itself (or null when Db is not ready)
