Build Automation & CI Pipeline

1. Install Node.js

Download dan install Node.js dulu: Node.js Official Website

2. Buat Folder Project

Buka:

• CMD

lalu ketik dibawah ini:

mkdir tugas-devops

masuk ke folder:

cd tugas-devops

3. Inisialisasi Project Node.js

npm init -y

Nanti otomatis akan membuat file: package.json

4. Install Express.js

npm install express

5. Install Dev Dependencies

npm install --save-dev nodemon eslint jest supertest

Buat File Server

1. Buat file index.js

const express = require("express");

const app = express();

app.get("/", (req, res) => {
  res.send("Hello DevOps");
});

app.listen(3000, () => {
  console.log("Server berjalan di port 3000");
});

2. Setup npm Scripts

Buka file:

package.json

Cari bagian:

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
}

Ubah jadi:

"scripts": {
  "dev": "nodemon index.js",
  "start": "node index.js",
  "build": "echo Build Success",
  "test": "jest",
  "lint": "eslint ."
}

Jalankan Nodemon:

npm.cmd run dev

    const res = await request(app).get("/");

    expect(res.statusCode).toBe(200);
    expect(res.text).toBe("Hello DevOps");
  });
});
