Kohana HAPI

HyperMedia Application Programming Interface - A Kohana module to use as a framework for building HTTP APIs.

In development. Do not use. It is expected that the major (backwards incompatible) versions will be increased rapidly.

What it is

• Framework for adding API support to your Kohana project
• Unfinished
• Rather strict than general-purpose

What it is not

• RESTful - Well, a bit, but missing [level three of the API maturity model](http://www.crummy .com/writing/speaking/2008-QCon/act3.html)
• Scalable and optimized - mean for one server, one client approach where client is under vendor control
• Tested

Installation

• Clone and enable the module. Use a git submodule, download the zip or add a Composer dependency
• Add a route to the API controller:

<?php
Route::set(
	'api',
	'api(/<controller>(/<id>(/<action>)))'
)
	->defaults(
	array(
		'directory'  => 'API/V1/',
		'controller' => 'About',
		'action'     => 'index'
	)
);

• Create APPPATH/classes/Controller/API/V1/Main.php - extends Controller_HAPI
• Create APPPATH/classes/Controller/API/V1/About.php - extends Controller_API_V1_Main
• In the action_index, write:

<?php
$this->hapi(['about' => 'Hello, world']);

• Make a HTTP GET query to `BASE_URL/api/v1/about

TODO

• Remove some of the hardcoded values to support not only JSON
• Document code, wiki, gh-pages
• Improve architecture
• Improve API semantics: provide meaningful error and status messages in response body
• Work towards achieving REST
