basic-auth-mongoose v0.1.1

#basic-auth-mongoose

Basic-auth is a Mongoose plugin that provides password-based user authentication for your Mongoose schema.

Basic-auth provides:

• Required username and password properties
• A simple authenticate method to use when signing users into your service
• Automatic password encryption
• Framework agnostic authentication and storage. Use it with Express, Passport, or on it's own.

##Installation

$ npm install basic-auth-mongoose

##Usage

###Mongoose Plugin

Basic-auth allows you to add password-based authentication to any Mongoose schema. Let's say you're working on a site where your basic User schema is shaping up like so:

var mongoose = require('mongoose');

var userSchema = new mongoose.Schema({
	email : String,
	first : String,
	last  : String,
});

To add authentication functionality, all you need to do is plugin basic-auth, and create your new User model:

userSchema.plugin(require('basic-auth'));
var User = mongoose.model('User', userSchema);

####Authentication Properties

Plugging in basic-auth will add two required properties on top of your original User schema: username and password. Just fill in those credentials when you're creating a user, and the user's password will be automatically encrypted for secure storage.

var tom = new User({
	email : 'tom@test.com',
	first : 'Tom',
	last  : 'Smith',
	username : 'toms1234',
	password : 'secret'
});

tom.save(function (err, user) {
	if (err) // handle
	else {
		console.log('User is saved and password is encrypted!!');
	}
});

####Methods

In addition to the username and password properties, you'll also get a handy user.authenticate(password) method. This method accepts a plain text password, and will return true if the password is correct, and false otherwise.

User.findOne({'username' : 'toms1234'}, function (err, tom) {
	if (err) // handle
	else {
		tom.authenticate('wrong-password'); // returns false
		tom.authenticate('secret'); // returns true
	}
});

####Sugar

Using basic-auth will also give you an id property, which will return the auto-generated MongoDB _id. To use, simply call:

tom.id  // returns MongoDB _id (e.g. 5A0009284I2)

###Options

You can configure the hashing algorithm used to encrypt the user's password. By default, basic-auth uses 'sha256'. To change the encryption method, simply pass in the encryptionMethod option when applying basic-auth:

var options = { 'encryptionMethod' : 'sha1' };
userSchema.plugin(require('basic-auth', options));

You are free to choose any of the hashing algorithms made available by Node's crypto library. Examples are sha1, sha256,sha512,md5.

###Examples

A full example of using basic-auth for a simple login / registration system is coming soon.

###Contributions

Inspired by saintedlama's passport-local-mongoose module.

Also, thanks to alexyoung for his Nodepad tutorial on Daily JS. This module reuses some of the password encryption techniques found there.
