🧭 Roadmap: Asisten AI ala Jarvis (Versi Realistis)

🧱 Fase 1 – Pondasi Dasar

• Tujuan: Bangun backend sederhana pakai GPT-4 API untuk jadi otak si "Jarvis".

DEMO Jarvis ChatVersion

Jarvis CLI

Langkah:

• Setup akun OpenAI API
• Bikin server backend (Node.js atau Python FastAPI)
• Koneksi ke GPT-4 API
• Buat endpoint /ask untuk tanya jawab
• Integrasi antarmuka (Web, atau BotTelegram)

⚙️ Contoh Kode Awal (Node.js + Express + GPT-4 API)

install depensi

npm init -y
npm install express axios dotenv

.env

OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

index.js

const express = require('express');
const axios = require('axios');
require('dotenv').config();

const app = express();
app.use(express.json());

const GPT_ENDPOINT = 'https://api.openai.com/v1/chat/completions';

app.post('/ask', async (req, res) => {
  const userMessage = req.body.message;

  try {
    const response = await axios.post(
      GPT_ENDPOINT,
      {
        model: 'gpt-4o',
        messages: [{ role: 'user', content: userMessage }],
      },
      {
        headers: {
          'Authorization': `Bearer ${process.env.OPENAI_API_KEY}`,
          'Content-Type': 'application/json',
        },
      }
    );

    const reply = response.data.choices[0].message.content;
    res.json({ reply });
  } catch (error) {
    console.error(error?.response?.data || error.message);
    res.status(500).json({ error: 'Something went wrong' });
  }
});

app.listen(3000, () => {
  console.log('🧠 AI server berjalan di http://localhost:3000');
});

🔗 Fase 2 – Integrasi Antarmuka

• Web dashboard (pakai Bootstrap + Jekyll)
• CLI interface (langsung ngetik di terminal)
• Telegram bot (cocok untuk mobilitas)
• Voice input (pakai Whisper atau Google STT)

🧠 assets/js/script.js

const form = document.getElementById("chat-form");
const input = document.getElementById("user-input");
const chatBox = document.getElementById("chat-box");

form.addEventListener("submit", async (e) => {
  e.preventDefault();
  const message = input.value.trim();
  if (!message) return;

  appendMessage("user", message);
  input.value = "";

  appendMessage("jarvis", "⏳ Sedang berpikir...");

  const res = await fetch("/ask", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ message }),
  });

  const data = await res.json();

  chatBox.lastChild.remove();
  appendMessage("jarvis", data.reply);
});

function appendMessage(role, text) {
  const div = document.createElement("div");
  div.className = role;
  div.textContent = text;
  chatBox.appendChild(div);
  chatBox.scrollTop = chatBox.scrollHeight;
}

✅ Jalankan:

node server/index.js

🔌 Fase 3 – Control Center

• Tujuan: Jadikan Jarvis lebih dari sekadar ngobrol.

• Home automation (pakai MQTT + ESP32)
• Firebase/Firestore (untuk simpan & ambil data)
• Kalender Google (via OAuth2)
• Kontrol lampu/AC/TV (pakai IFTTT atau Tuya API)

🔮 Next Step:

• BOT TELEGRAM
• Mode suara (voice-to-text)
• Riwayat percakapan
• Login user

🤖 BOT Telegram

Bot yang jadi mulutnya si Jarvis. Bot ini akan:

• Terima pesan dari kamu via Telegram
• Kirim ke GPT-4 API
• Balas langsung ke chat dengan gaya smart assistant

🧠 Alur Kerja Bot Jarvis via Telegram

Telegram Chat → Bot Telegram → GPT-4 API → Balas ke Telegram

🔧 Alat Tempur

• Node.js

• node-telegram-bot-api

• Install dulu

npm install node-telegram-bot-api express axios dotenv

.env

OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
TELEGRAM_BOT_TOKEN=isi_dari_BotFather

assets/js/bot.js

require('dotenv').config();
const TelegramBot = require('node-telegram-bot-api');
const axios = require('axios');

const bot = new TelegramBot(process.env.TELEGRAM_BOT_TOKEN, { polling: true });
const GPT_API = 'https://api.openai.com/v1/chat/completions';

bot.on('message', async (msg) => {
  const chatId = msg.chat.id;
  const userMessage = msg.text;

  // Kirim placeholder "Jarvis sedang mikir..."
  await bot.sendMessage(chatId, '🧠 Jarvis sedang memproses...');

  try {
    const res = await axios.post(
      GPT_API,
      {
        model: 'gpt-4o',
        messages: [{ role: 'user', content: userMessage }],
      },
      {
        headers: {
          Authorization: `Bearer ${process.env.OPENAI_API_KEY}`,
          'Content-Type': 'application/json',
        },
      }
    );

    const reply = res.data.choices[0].message.content;
    await bot.sendMessage(chatId, `🤖 Jarvis:\n${reply}`);
  } catch (err) {
    console.error(err.response?.data || err.message);
    await bot.sendMessage(chatId, '⚠️ Jarvis gagal berpikir. Coba lagi ya.');
  }
});

✅ Jalankan Bot:

node serve/bot.js

🧪 Tes:

• Buka Telegram
• Cari bot kamu (nama yang kamu kasih via @BotFather)
• Chat: "Hai Jarvis, kamu bisa bantuin nyusun ide bisnis?"

🔮 Next Step:

• Mode suara (voice-to-text)
• Riwayat percakapan
• Login user
