Ghost for JSON

This repository is a fork of Ghost with the minimum set of changes in order to have Ghost provide a consumable JSON API. It is designed to run with GhostJSON as the theme.

The current list of changes:

• Added two Handlebars helpers
  • safe: Escape HTML for embedding into JSON
  • cleanJSON: Remove excess whitespace from "pretty" JSON
• Add appropriate headers to frontend pages
  • Content-Type: application/json
  • Access-Control-Allow-Origin: *

This fork is based off of the stable branch of Ghost.

Running

Currently, the easiest way to run this fork is cloning from Github. Follow the official Ghost instructions, but make sure you're on the correct branch.

Issues

If you run across any issues, or have a cleaner way of providing the needed features, please let me know! I'm in the process of dog-fooding this, so we should be close.
