MEAN, get some stuff out of MONGO DB, show JSON in restful style

I've been working on this lately.

The JavaScript style is ripe, I feel sure soon, but there is a feeling in my heart, Django and mean this structure, make big not.

Because this structure of MVC feels less rigorous than spring, is it my bias? The level is not enough? Not forced to do it?

DB Layer notation:

/** * Created by Sahara on 2016/7/5.*/varMongoose = require (' Mongoose '));varDburi = ' mongodb://localhost/loc8r ';varGracefulshutdownmongoose.connect (Dburi); Mongoose.connection.on (' Connected ',function() {Console.log (' Mongoose connected to ' +Dburi);}); Mongoose.connection.on (' Error ',function(Err) {Console.log (' Mongoose connection error: ' +err);}); Mongoose.connection.on (' Disconnected ',function() {Console.log (' Mongoose disconnected ');});varReadLine = require ("ReadLine");if(Process.platform = = = "Win32"){    varRL =Readline.createinterface ({input:process.stdin, output:process.stdout}); Rl.on ("SIGINT",function() {Process.emit ("SIGINT"); });} Gracefulshutdown=function(MSG, callback) {Mongoose.connection.close (function() {Console.log (' Mongoose disconnected through ' +msg);    Callback (); });}; Process.once (' SIGUSR2 ',function() {Gracefulshutdown (' Nodemon restart ',function() {Process.kill (Process.pid,' SIGUSR2 '); });}); Process.on (' SIGINT ',function() {Gracefulshutdown (' App termination ',function() {Process.exit (0); });}); Process.on (' SIGTERM ',function() {Gracefulshutdown (' Heroku app shutdown ',function() {Process.exit (0); });}); Require ('./locations ');

Database definition:

/** * Created by Sahara on 2016/7/5.*/varMongoose = require (' Mongoose '));varOpeningtimeschema =NewMongoose. Schema ({days: {type:string, Required:true}, Opening:string, closing:string, closed: {Type:boolean, Required:true}});varReviewschema =NewMongoose. Schema ({author:string, rating: {type:number, Required:true, min:0, Max:5}, Reviewtext:string, CreatedOn: {type:date,"Default": Date.now}});varLocationschema =NewMongoose. Schema ({name: {type:string, Required:true}, Address:string, Rating: {type:number,"Default": 0, min:0, max:5}, Facilities: [String], coords: {type: [number], index:' 2dsphere '}, Openingtimes: [Openingtimeschema], Reviews: [Reviewschema]}); Mongoose.model (' Location ', locationschema);

Routing layer notation:

varExpress = require (' Express ');varRouter =Express. Router ();varCtrllocations = require ('.. /controllers/locations ');varCtrlreviews = require ('.. /controllers/reviews ');//LocationsRouter.get ('/locations ', ctrllocations.locationslistbydistance); Router.post ('/locations ', ctrllocations.locationscreate); Router.get ('/locations/:locationid ', Ctrllocations.locationsreadone); Router.put ('/locations/:locationid ', ctrllocations.locationsupdateone); router.Delete('/locations/:locationid ', ctrllocations.locationsdeleteone);//ReviewsRouter.post ('/locations/:locationid/reviews ', ctrlreviews.reviewcreate); Router.get ('/locations/:locationid/reviews/:reviewid ', Ctrlreviews.reviewreadone); Router.put ('/locations/:locationid/reviews/:reviewid ', ctrlreviews.reviewupdateone); router.Delete('/locations/:locationid/reviews/:reviewid ', Ctrlreviews.reviewdeleteone); Module.exports= Router

Controller notation:

/** * Created by Sahara on 2016/7/6.*/varMongoose = require (' Mongoose '));varLoc = Mongoose.model (' Location ');varSendjsonresponse =function(res, status, content) {res.status (status); Res.json (content);}; Module.exports.locationsListByDistance=function(req, res) {Sendjsonresponse (res,$, {"status": "Success"});}; Module.exports.locationsCreate=function(req, res) {Sendjsonresponse (res,201, {"status": "Success"});}; Module.exports.locationsReadOne=function(req, res) {if(Req.params &&Req.params.locationid) {Loc. FindByID (Req.params.locationid). EXEC (function(err, location) {if(!Location ) {Sendjsonresponse (res,404, {                        "Message": "LocationID not Found"                    }); return; } Else if(Err) {Sendjsonresponse (res,404, err); return; } sendjsonresponse (res,200, location);    }); } Else{sendjsonresponse (res,404, {            "Message": "No LocationID in Request"        }); }};module.exports.locationsupdateone=function(req, res) {Sendjsonresponse (res,$, {"status": "Success"});}; Module.exports.locationsDeleteOne=function(req, res) {Sendjsonresponse (res,204, {"Status": "Success"});};

Modification of App.js:

varExpress = require (' Express ');varPath = require (' path ');varFavicon = require (' Serve-favicon '));varLogger = require (' Morgan ');varCookieparser = require (' Cookie-parser '));varBodyparser = require (' Body-parser ')); require ('./app_api/models/db ');varRoutes = require ('./app_server/routes/index '));varRoutesapi = require ('./app_api/routes/index '));varUsers = require ('./app_server/routes/users '));varApp =Express ();//View engine SetupApp.set (' Views ', Path.join (__dirname, ' app_server '), ' views ')); App.set (' View engine ', ' Jade ');//uncomment after placing your favicon in/public//App.use (Favicon (Path.join (__dirname, ' public ', ' Favicon.ico ' ));App.use (Logger (' dev ')) ; App.use (Bodyparser.json ()); App.use (bodyparser.urlencoded ({extended:false}); App.use (Cookieparser ()); App.use (express.static (Path.join,' Public ')) ; App.use (‘/‘, routes); App.use ('/api ', Routesapi); App.use ('/users ', users);//catch 404 and forward to error handlerApp.use (function(req, res, next) {varErr =NewError (' Not Found '); Err.status= 404; Next (err);});//Error Handlers//Development Error Handler//Would print StackTraceif(App.get (' env ') = = = ' Development ') {App.use (function(Err, req, res, next) {Res.status (Err.status|| 500); Res.render (' Error ', {message:err.message, error:err}); });}//Production Error Handler//no stacktraces leaked to userApp.use (function(Err, req, res, next) {Res.status (Err.status|| 500); Res.render (' Error '{message:err.message, error: {}}); Module.exports= app;
