Creating New Quasar Project using Windows 7

run

npm i -g quasar-cli --no-optional

After successfully installing quasar, we can execute this command :

Above steps are only executed once, so when we wanto create another quasar project in future, we don't have to do those commands again. We can simply just create our first quasar app yeaaah.... :D
Ok let's create our first quasar app by running this command :

Now we can see the project structure of quasar app like this :

Next let's jump to our quasar project app, 'cd quasar_first' and then execute 'npm install' for installing quasar dependency ....

Last... Just run quasar by executing 'quasar dev'

How to check object property in Node.js

Here's the way...

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

var my_obj = { name : "Hisoka", skills: "Bungejigum" }; if(my_obj.hasOwnProperty('status')) { console.log(" my object has status property"); } else { console.log(" status is NOT in there"); } if(my_obj.hasOwnProperty('skills')) { console.log(" my object has skills property"); } else { console.log(" skills is NOT in there"); } /** * Another way for checking property is using 'in'. * but BE CAREFUL! The in operator matches all object keys, * including those in the object's prototype chain. * So it's preferred to use hasOwnProperty */ console.log("\n"); if('status' in my_obj) { console.log(" status is in there"); } else { console.log(" status is NOT in there"); } if('skills' in my_obj) { console.log(" skills is in there"); } else { console.log(" skills is NOT in there"); }

Dasa Jade Template - NodeJS

Di postingan sebelumnya kita udah ngekonfig node express yg basic... Naah disini kita nyoba2 jade template yg basic2... :)
Contoh jade templatenya bisa dilihat di layout.jade didalam folder views kyk gambar di bawah :

Terus 'block content' itu bisa dilihat didalam index.jade kyk gini :

Tampilannya seperti ini :

SailsJS untuk Pemula - part I

Pertama-tama mari kita install SailsJS-nya pake npm ajjah. Silahkan jalankan perintah ini :

'npm i sails -g --no-optional'

Naah... disitu -g flag buat global directory, trus --no-optional biar g' usah nginstall dependencies di windows (soalnya skrg lg make windows 7)

Silahkan ditunggu beberapa menit biar packagenya kedownload ke repo local kita. Tar klu udah selese, kita bisa nyoba pake command 'sails -h' yg hasilnya kek gini :

Naaah... berikutnya kita ngebuat project sails baru pake perintah ini 'sails new myFirstSails'

myFirstSails itu nama folder project kita tar klu udah jadi.......

Struktur folder utama project sailsnya kyk gini :

Terus folder model dan controllernya ada didalam folder api kyk gini :

Naah...terakhir klu projectnya mau di run, pake perintah 'sails lift'

Port defaultnya 1337... Kalu dibuka tampilannya seperti ini :

Cooool...... Cukup sekian dl untuk part pertama... :D

Nodejs Express Generator

Next, let's install express-generator by running this command "npm i express-generator -g --no-optional" 

I'm ruunning nodejs in windows 7, so I need that --no-optional flag in order to prevent fsevent error message :D

After installing express-generator, we can see it's folder inside node-modules like this 

Next.... Let's test our express generator by running 'express -h' like this :

Ok... Let's create our first express-generator project 'express myFirstExpGen'

After running that command, we can see our directory content like this :

Btw,, actually we can specify view engine by using --v=pug|jade|ejs and etc. We also can specify css engine by using --c=less|stylus|sass|compass.... In this post I'm using default engine so it will be jade for view and plain css for css.

Next, let's run 'npm install' for installing project dependencies..

Last... Let's run our express, for windows, we can use this command :

'set DEBUG=projectDirName:* & npm start'

And then open localhost:3000 

Yeeei.... btw.... www file inside of  bin directory is our starting project file, and that file loads app.js.

Aaaand in this default project, we already have /users so if we open the page we will gonna see something like this :

It's content :
