How to set up stress-free SSL on an OS X development machine
How to set up stress-free SSL on an OS X development machine
One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.
Most workflows make the following compromises:
Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying

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:
Handlebars random JavaScript expression execution, with an IF helper with whatever logical operands and whatever arguments, and few more goodies.

/* a helper to execute an IF statement with any expression
USAGE:
-- Yes you NEED to properly escape the string literals, or just alternate single and double quotes
-- to access any global function or property you should use window.functionName() instead of just functionName()
-- this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt later
