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

API Golden Rules

Never Expose DB Results Directly

  1. If you rename a field, then your users are fucked. Convert with a hardcoded array structure.
  2. Most DB drivers [for PHP] will show integers as numeric strings and false as "0", so you want to typecast them.
  3. Unless you're using an ORM with "hidden" functionality, people will see passwords, salts and all sorts of fancy codes. If you add one and forget to put it in your $hidden array then OOPS!

Use the URI sparingly, and correctly

  1. Use the query string for paired params instead of /users/id/5/active/true. Your API does not need to be SEO optimised.
  2. ?format=xml is stupid, use an Accept: application/xml header. I added this to the CodeIgniter Rest Server once for lazy people, and now people think it's a thing. It's not.
