API Builder for Agnostic Router

Generate a router for a given class, using a config

Or generate an object that will then pass arguments to its functions to a router (e.g.: Create an object of functions in the browser, to match the object available on the server)

TODOs

• Generate config automatically from JSDoc

Methods

toObject

function(apiConfig, callback)

callback(functionName, urlPath, requestArguments, functionCallback);

toRouter

function(apiConfig, targetObject, [router])

Usage

// Shared config, on the server and client
var apiConfig = {
	"lookup": {
		"pattern": "/lookup",
		"arguments": [
			{"name": "title", "level": 0, "source": "query"},
			{"name": "author", "level": 1, "source": "query"}
		]
	}
};

// On the server
var apiObject = {
	lookup: function() {
		if(arguments.length == 3) { // title, author, callback
			if(arguments[0] == 'War and Peace' && arguments[1] == 'Leo Tolstoy')
				arguments[2](null, '0140447938');
			else
				arguments[2]('not_found', null);
		}
	}
};

// Generate a router
var router = ApiRouter.toRouter(apiConfig, apiObject);

// Call from the client, through a public-facing interface (e.g.: HTTP server)
router.route('request', '/lookup', {query: {title: 'War and Peace', author: 'Leo Tolstoy'}}, function(error, isbn) {
	if(error)
		throw new Error('Function returned error');
	if(isbn != '0140447938')
		throw new Error('Function returned wrong result');
	console.log('Found the right book');
});

// On the client
function routeCallback(functionName, apiPath, request, callback) {
	// Make a conenction to the public interface here
	// Call callback when done
}

var apiObject = ApiRouter.toObject(apiConfig, routeCallback);

apiObject.lookup('War and Peace', 'Leo Tolstoy', function(error, isbn) {
	if(error)
		throw new Error(error);
	console.log("The requested book has ISBN", isbn);
});
