mailchimp-app/index.js

A Mailchimp express sub-app to mount on any project, for easy integration

	var express    = require('express');
	var bodyParser = require('body-parser');
	var app        = express();

	module.exports = function( config, opts ){

		opts = opts || {};

		var mailchimp  = require('./mc-mdw')( config, opts );
		var errHandler = opts.errHandler ? opts.errHandler() : mailchimp.handle("error");

		// Setup : ensure bodyparser and urlencoded are being used
		// Merge req.query and req.body in req.sent object
		app.use( bodyParser.json() );
		app.use( bodyParser.urlencoded({ extended: true }) );
		app.use( mailchimp.prepareRequest );

		// Make sure each requests is authorized based on who knows the secret
		app.use( mailchimp.authorize( config) );

		// Test routes, hello triggers a success and goodbye an error
		app.get('/hello', mailchimp.handle("hello"));
		app.get('/goodbye', mailchimp.handle("goodbye"));

		app.get('/users/:mailchimp_id', mailchimp.handle("get_user"));
		app.get('/users', mailchimp.handle("list_users"));
		app.post('/users', mailchimp.handle("subscribe"));

		 	When the email_address is updated, the app takes care of 3 steps. Mailchimp has a logic rules that
		 	makes it impossible for a user to just update his email. It has to be a new user. Hence the steps : 
				- deleting the former user
				- creating a brand new one
				- patching him with the previous values

		// Completely deletes the user from the list. 
		app.delete('/users/:mailchimp_id', mailchimp.handle("delete"));

		// Indicates if the ressource wasnt found
		app.all('*', mailchimp.handle("end"));


		app.use( errHandler );
