How to get facebook login working with Meteor and Cordova on iOS

Step 1: Make your local dev site internet accessible

Because there is an issue with OAuth2 login and localhost development, you currently have to deploy your meteor site to be able to test the Facebook login. A nice little workaround for this is to make the local instance of meteor accessible externally.

There is a great online guide for setting up port forwarding with your router and you can check your public external IP here.

For example, If you have an Apple router, simply open up Airport Utility on your Mac and click edit on your router, then go to the Network tab. Under Port Settings click the + icon and select Personal Web Sharing, setting all of the public and private ports to 3000. Make sure the private IP is set to your current computer IP.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

JavaScript Crypto Libraries

I start with a list and plan to create a comparison table.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.
