Waterlock Facebook Auth

Build Status NPM version Dependency Status

waterlock-facebook-auth is a module for waterlock providing a facebook authentication method for users either based on username.

Usage

npm install waterlock-facebook-auth

Set the following option in your waterlock.js config file

  • redirectUri is an optional property - use this if you want to override the computed redirectUri. This is useful for when you want to send an auth code to waterlock instead of having waterlock handle the entire auth flow for you. Useful for when you're developing an SPA which handles the authentication with something like Torii (EmberJs). See https://github.com/wayne-o/ember-waterlock-example - waterlock will validate the auth code with the provider and retrieve an access token which can be used to setup a session and return the JWT to your app
authMethod: [
	{
		name: "waterlock-facebook-auth",
		appId: "your-app-id",
		appSecret: "your-app-secret",
		redirectUri: 'redirectUri'
	}
]

Direct your user to /auth/login?type=facebook will initiate the oauth request. The callback uri is /auth/facebook_oauth2 if successfuly authenticated a user record will be created if a user is not found one will be created using the waterlines findOrCreate method

If you are using sails blueprints and have pluralized your REST API you can configure waterlock to pluralize the auth endpoints by including pluralizeEndpoints=true in the waterlock.js file:

module.exports.waterlock = {

  pluralizeEndpoints: true

}

Grabbing Facebook field values

By default, waterlock-facebook-auth stores the user's facebookId, name and email in the Auth model. In reality, Facebook returns more data than that.

To grab and store this, you will need to modify the add the fields in your Auth.js model...

// api/models/Auth.js
module.exports = {
	attributes: require('waterlock').models.auth.attributes({
		firstName: 'string',
		lastName: 'string',
		gender: 'string',
		timezone: 'number'
	})
}

...and then add a fieldMap object within the facebook authMethod in your waterlock.js config file which matches your model's fields to facebook's fields.

authMethod: [
	{
		name: "waterlock-facebook-auth",
		appId: "your-app-id",
		appSecret: "your-app-secret",
		fieldMap: {
			// <model-field>: <facebook-field>,
			'firstName': 'first_name',
			'lastName': 'last_name',
			'gender': 'gender',
			'timezone': 'timezone'
		}
	}
]
