// => Import dependencies

import express from "express";
import path from "path";
import { fileURLToPath } from "url"; // needed for __dirname in ES modules

// => Setup path helpers

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

// => Create Express app

const app = express();
const PORT = process.env.PORT || 8080;

// => Middleware

// Serve static files (HTML, CSS, JS, images, etc.) from the "public" directory
app.use(express.static(path.join(__dirname, "public")));

// Parse incoming JSON requests (useful for APIs)
app.use(express.json());

// Middleware for logging requests
app.use((req, res, next) => {
    console.log(`[${new Date().toISOString()}] ${req.method} ${req.url}`);
    next(); // Continue to the next middleware or route handler
});

// => Routes

// Serve main HTML page
app.get("/", (req, res) => {
    res.sendFile(path.join(__dirname, "public", "pages", "index.html"));
});

// Serve JSON data
app.get("/api/destinations", (req, res) => {
    res.sendFile(path.join(__dirname, "data", "destinations.json"));
});


// => Error Handling


// 404 Handler — runs when no route matches
app.use((req, res) => {
    res.status(404).send("<h3>❌ 404 Not Found — The page you're looking for doesn't exist.</h3>");
});

// General Error Handler — catches unexpected errors
app.use((err, req, res, next) => {
    console.error("🔥 Unexpected error:", err.stack);
    res.status(500).send("<h3>⚠️ 500 Internal Server Error — Something went wrong.</h3>");
});

// => Start the server

app.listen(PORT, (err) => {
    if (err) {
        console.error("❌ Failed to start the server:", err);
        process.exit(1);
    }
    console.log(`✅ Server running at: http://localhost:${PORT}`);
});
