nd-express-plugin

This is the first plugin that adds ExpressJS bindings using the annotation support from node-dependency.

What this module does is to allow you to create web services without the boilerplate code from ExpressJS.

Install

npm install --save nd-express-plugin

You''ll need to have installed node-dependency.

Node-dependency will automatically find this module and call all needed function to configure it, therefore you do not need to require it.

Somewhere in your source folder you can add JS files with the following annotations, this plugin will use node-dependency's auto discovery to find them and wire all the handlers.

Supported annotations:

 - @Get, @Post, @Put, @Patch, @Head, @Options, @Delete
 - @RequestHandler
 - @Interceptor
 - @ExpressConfiguration

@RequestHandler Used to indicated that a Class is a Request Handler.

• Targets: Class
• Parameters: a String representing the base url of that Class

Usages:

		// Without defining a base url
		'@RequestHandler'
		function Handler(){
				...
		}
		module.exports = Handler;

		// Base URL set to '/handler'
		'@RequestHandler("/handler")'
		function Handler(){
				...
		}
		module.exports = Handler;

HTTP Annotations: @Get, @Post, @Put, @Patch, @Head, @Options, @Delete
These annotations are used to indicate that a method from a RequestHandler class should be called when a request with the defined HTTP Method is made to the desired url.
You can receive a lot of parameters in those methods, like the request or the response

• Targets: Method
• Parameters: a String representing the url to listen

Usages

		'@RequestHandler("/handler")'
		function Handler(Model){
				
				'@Get'
				this.fetch = function(){
					return [{}]; // The returned value will be sent the same as 'response.send([{}])'
				}
				
				'@Post'
				this.create = function(body){
					// The response will have its send method call with the value resolved from the promise
					return Model.save(body);
				}

				'@Get("/id/:id")'
				this.find = function($id, done, error){
					// You can also use the done method to send the data
					Model.find({
						_id : $id
					}, done);
				}
		}
		module.exports = Handler;
