APA YANG BARU DARI RILIS SYMFONY 4

Pada minggu yang lalu saya menulis di blog saya bagaimana menginstalasi Symfony 3, nah kini telah rilis versi terbarunya yakni versi 4.seperti kita ketahui jika dibandingkan Framework lainnya Symfony banya disukai oleh para web developer karena beberapa sebab seperti keamanan yang dibuat terpisah atau Out of the box,Template engine yang mudah digunakan atau dikolaborasikan dengan Frontend developer,built in Email library,annotation atau Block doc PHP yang akan dibaca parsing oleh program sehingga kita bisa memanipulasi program tanpa merubah program bawaannya,kekhasan  yml atau yahoo markup language  yang sangat friendly  sehingga kita tidak perlu menggunakan tag html dan masih banyak lainnya

nah , apa yang baru dari versi 4 ini  ?

berikut saya ambil dari Halaman Symfony.com

Sebelumnya saya sudah menginstal versi3 sobat bisa melihatnya di link ini

http://idiuptocode.blogspot.com/2017/11/belajar-symfony-33.html

perbedaan cara penginstalan  adalah pada saat awal perintah command , jika sebelumnya kita menggunakan perintah  php symfony new bloglist bloglist adalah nama contoh project yang saya buat,Sobat bisa menginstalnya dengan nama yanng berbeda.Andaikan kita mengetikan baris perintah yang sama maka pada tampilan command akan muncul warning seperti ini :

  [RuntimeException]

  The selected version (4.0.0) cannot be installed because it does not exist.

  Execute the following command to install the latest stable Symfony release:

  symfony new symfony4

new <directory> [<version>]

maka perintah pada penginstalan Versi 4 menggunakan perintah seperti ini 

composer create-project symfony/skeleton my-project

dan sobat bisa mengganti " my project" menjadi nama blog sobat

berikut merupakan List Download dari versi terbaru kini yakni veri 4 yang saya instal di direktori laragon di drive c

 What's next?


  * Run your application:
    1. Change to the project directory
    2. Execute the php -S 127.0.0.1:8000 -t public command;
    3. Browse to the http://localhost:8000/ URL.

       Quit the server with CTRL-C.
       Run composer require server for a better web server.

  * Read the documentation at https://symfony.com/doc



C:\laragon\www

Sobat perhatikan pada notice yang saya list warna biru,maka kita disarankan untuk mengganti direktori project maka ikuti  perintah command selanjutnya dengan mengetikan perintah 

php -S 127.0.0.1:8000 -t public

seandainya Sobat langsung menjalankan di browser sebenarnya bisa saja dilakukan hanya saja sobat menambahkan /public dibelakang url project sobat dan tampilannya akan seperti ini

Jika sobat ingin menggantinya dan terkendala perintah yang disarankan diatas maka sobat bisa melanjutkan dengan mengetik baris seperti ini , jika Sobat tidak dalam folder C, silahkan sesuaikan karena disini saya contohkan menggunaan laragon yang ada di folder C

C:\laragon\www
λ cd my-project

C:\laragon\www\my-project

λ composer require server

maka Command aakan run seperti ini

Using version ^4.0 for symfony/web-server-bundle
./composer.json has been updated

Executing script cache:clear [OK]

Executing script assets:install --symlink --relative public [OK]

dan pada browser sobat sudah bisa menggantikan alamut url "http://127.0.0.1:8000"

cara yang paling mudah adalah jika download langsung dari webserver , misalkan disini saya mengunakan Webserver laragon tinggal ke menu laragon dan pilih quick creat 

secara otomatis akan menjalankan download setelah sobat menentukan nama dari project yang akan soabat buat, disini saya membuat dengan nama symblog, maka tampilan pada command akan berjalan seperti berikut

C:\laragon\www\symblog>

lihat , beberapa list yang saya cetak biru lagi, disini Sobat diminta mengisi beberapa parameter, dari mulai host dan pengaturan standard lainnya, jika sobat ingin mengaturnya nanti dan hanya akan melakukan konfigurasi default maka tinggal tekan enter dan enter saja.Disini sobat akan diberikan alam url yang lebih pendek dan mudah untuk digunakan dengan nama http://symblog.dev/ , sangat mudah dan simple kan ?, tapi versinya 3.4 .

 nah sampai disini sobat sudah mempunyai project symfony baru dengan versi 4.0
sekian dulu tutorial dari saya Jika sobat ingin melihat Video pengalaman Symfony 4 bisa melihat vdeonya disini 

 semoga bisa membantu.
