Lets Destroy Node.js developer.

"When you are designing a program there are things that might be cute to add in, you always regret those."

Ryan Dahl - 10 Things i Regret About Node.js @ JSConf Europe

Installation

Install Deno For Windows

Kita akan melakukan instalasi Deno menggunakan Package Manager yang disebut dengan Chocolatey :

1. Install Chocolatey Package Manager

Jalankan Powershell (run as administrator), kemudian eksekusi perintah di bawah ini :

Setelah itu eksekusi perintah powershell di bawah ini :

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Proses instalasi sedang di lakukan, kita akan memiliki directory Chocolatey Package Repository di :

C:\ProgramData\chocolatey\lib

Kita juga akan memiki directory untuk Chocolatey Binary di :

C:\ProgramData\chocolatey\bin

Pastikan chocholatey sudah terpasang dengan cara mengeksekusi perintah di bawah ini dalam cmd.exe :

choco

Maka informasi versi choco akan di tampilkan :

Chocolatey v0.10.15

2. Install Deno Via Package Manager

Lakukan instalasi Deno menggunakan perintah di bawah ini :

choco install deno

Jika berhasil maka dalam directory Chocolatey Package Repository, package Deno akan tersimpan :

C:\ProgramData\chocolatey\lib\deno

3. Check Deno

Check Eksistensi Deno dengan mengeksekusi perintah di bawah ini :

deno -V

Jika berhasil maka akan muncul informasi versi deno yang sedang kita gunakan :

Install Deno For Linux

1. Install Deno via Curl

1. Buka terminal eksekusi perintah di bawah ini :

   curl -fsSL https://deno.land/x/install/install.sh | sh 
   

2. Jika berhasil maka proses instalasi akan dilakukan :

   

   jalankan command deno -V, apabila muncul "commnad not found: deno" maka lanjut ke step berikutnya

3. Menambahkan path ke bash_profile atau bashrc

   • Eksekusi perintah nano .bashrc atau nano .zshrc tergantung dari shell yang kalian gunakan

   • Salin perintah di bawah ini dan simpan di baris terakhir di .bashrc atau .zshrc

     export DENO_INSTALL="/home/<username>/.deno"
     export PATH="$DENO_INSTALL/bin:$PATH"

Deno 101

Untuk memulai menggunakan Deno ada 3 langkah yang bisa kita gunakan :

REPL Mode Execution

Untuk menggunakan Deno dalam Mode REPL (Read – Eval – Print – Loop), pada cmd.exe ketik :

deno

Eksekusi statement di bawah ini :

1+1

Kemudian eksekusi statement di bawah ini untuk menampilkan pesan Hello World

console.log("Hello World")

Jika berhasil maka akan memproduksi :

Hello World

Jika ingin keluar dari REPL Mode, klik CTRL+Shift+D.

Script Execution

Jika kita ingin mengeksekusi sebuah file javascript yang telah diubah menjadi typescript menggunakan deno, eksekusi perintah di bawah ini :

deno run https://deno.land/std/examples/welcome.ts

Maka anda akan melihat output informasi seperti di bawah ini :

Download https://deno.land/std/examples/welcome.ts
Warning Implicitly using master branch https://deno.land/std/examples/welcome.ts
Compile https://deno.land/std/examples/welcome.ts
Welcome to Deno 🦕

Eval Mode

Mengeksekusi dalam mode eval jarang sekali dilakukan dan hanya digunakan di kasus-kasus tertentu saja. Di versi node.js sebelumnya eval mode merupakan model eksekusi yang rentan untuk dieksploitasi, pada deno kerentanan tersebut sudah di perbaiki.

Untuk mengetahui cara mengeksekusi dalam eval mode, eksekusi contoh kode di bawah ini :

deno eval "console.log(30933 + 404)"

Deno Command

Deno memiliki Options & Sub Commands yang dapat kita gunakan :

1. Deno Options

Saat kita mengeksekusi perintah dengan options di bawah ini :

deno --help

Terdapat struktur yang bisa kita pelajari :

2. Deno Sub Command

Saat kita mengeksekusi perintah dengan sub command di bawah ini :

deno run https://a.com/test/hello.ts

Terdapat struktur yang bisa kita pelajari :

3. Deno Command Structure

Kita dapat melihat gambaran besar lebih jauh dari Deno Options dan Sub-commands dengan gambar di bawah ini :

Run Javascript & Typescript Files

Buatlah dua buah file dengan nama Example.js dan Example.ts dan tulis kode di bawah ini :

import { serve } from "https://deno.land/[email protected]/http/server.ts";
for await (const req of serve({ port: 8000 })) {
  req.respond({ body: "Hello World\n" });
}

Kemudian eksekusi perintah di bawah ini :

deno run Example.js

Anda akan mendapatkan error sebagai berikut :

error: Uncaught PermissionDenied: network access to "0.0.0.0:8000", run again with the --allow-net flag

Ini bukti bahwa deno memiliki mekanisme keamanan yang baik dengan menerapkan konsep Access Control yang baik, agar kita dapat menggunakannya tambahkan --allow-net flag setelah sub command :

deno run --allow-net Example.js

Buka browser anda dan kunjungi 127.0.0.1:8000

Untuk mengeksekusi typescript file :

deno run --allow-net Example.ts
