NodeJS RESTful Service with Gulp and Express

NodeJSRESTfulServicewithGulpandExpress

HowtomakeExpressJSandServicesLayerworkingtogether?

Hereismyapp.js

/*jslintnode:true*/

'usestrict';

varexpress=require('express');

varbodyParser=require('body-parser');

varrouter=require('./route');

varapp=express();

app.use(bodyParser.urlencoded({extended:false}));

app.use(bodyParser.json());

app.use('/',router);

app.set('port',process.env.PORT||3000);

app.listen(app.get('port'));

console.log('Runningserveronport'+app.get('port')+'.');

Hereistheroute.jswhichismyrouter,butalsoIconstructtheserviceslayerhereaswell.

/*jslintnode:true*/

'usestrict';

varexpress=require('express');

varconfig=require('./lib/config');

varlog4js=require('log4js');

varHashMap=require('hashmap').HashMap;

varemailscan=require('./lib/emailservice');

varaccount_controller=require('./controller/account.controller.js');

varjob_controller=require('./controller/job.controller.js');

varattachment_controller=require('./controller/attachment.controller.js');

//holdalltheservices

varservices=newHashMap();

//setupconfig

config.load(__dirname+'/config','test-conf');

services.set('config',config);

//setuplogger

log4js.configure(__dirname+'/config/log/'+config.data.logConfigFileName,config.data.log4js);

varlogger=log4js.getLogger('root');

services.set('logger',logger);

//setupemailscan

emailservice.services=services;

emailservice.init(services);

services.set('emailscan',emailscan);

//setupcontrollers

account_controller.init(services);

job_controller.init(services);

attachment_controller.init(services);

//routingconfiguration

varrouter=express.Router();

router.get('/accounts/:email',account_controller.getAccountByEmail);

router.post('/jobs/scan',job_controller.scanJobs);

router.get('/jobs/:accountId/:messageId',job_controller.getJob);

module.exports=router;

Hereisoneexampleofthecontroller,whichisaccount.controller.js

/*jslintnode:true*/

'usestrict';

varHashMap=require('hashmap').HashMap;

varservices=null;

module.exports={

getAccountByEmail:function(req,res){

//services

varemailscan=services.get('emailservice');

varlogger=services.get('logger');

//params

varemail=req.params.email;

emailscan.fetchAccountInfoByEmail(email,function(err,account){

logger.debug("accountinfo="+account.id);

res.json(account);

});

},

init:function(myservices){

services=myservices;

}

};
