DISCLAIMER: This is not supported code, use at your own risk.

This is a helper buildpack for installing and keeping an updated version of CraftCMS without committing it to your repo.

Ensure that you're using the default Craft folder structure:

app/
	craft/
	public/

Also ensure that you have a db.php in your craft/config directory.

Add this buildpack as the last buildpack in your heroku settings, after heroku/php

heroku buildpacks:set heroku/php
heroku buildpacks:add --index 1 https://github.com/dictions/heroku-buildpack-craftcms

Buildpack Requirements

This buildpack just manages Craft installation. As such, it relies on the heroku/php buildpack for PHP, Composer, and NGINX.

Add a Procfile in your app's root directory:

web: bin/start.sh

Add a composer.json file in your app's root directory:

{
	"require": {
		"php": "^5.3.0",
		"ext-mbstring": "*",
		"ext-imagick": "*"
	},
	"require-dev": {
		"heroku/heroku-buildpack-php": "*"
	}
}

You can configure the version of CraftCMS you need via CRAFT_VERSION and CRAFT_BUILD environment variables.

Improvements to be made later.

1. Better Procfile detection. Right now there will always be a Procfile in the root because of heroku/php.
2. Better support for choosing between NGINX/Apache
3. Install needed dependencies & composer plugins autonomously. I don't think composer.json is actually installing dependencies because composer runs before the Craft buildpack.
