## Basic Usage

Here is a basic example to get started with Aroma.js:

```javascript
import Aroma from "aroma.js";

const app = new Aroma();

// Middleware example
app.use((req, res, next) => {
  console.log(`Request received: ${req.method} ${req.url}`);
  next();
});

// Simple route
app.get("/", (req, res) => {
  res.send({ message: "Hello, world!" });
});

// Start server
app.listen(3000, () => {
  console.log("Aroma.js server running on http://localhost:3000");
});
```

## API Documentation

### Routes

Define HTTP methods for handling routes.

```javascript
app.get("/path", handler); // GET request
app.post("/path", handler); // POST request
app.put("/path", handler); // PUT request
app.delete("/path", handler); // DELETE request
```

### Router

Aroma.js provides a Router class for modular routing. You can define routes in a separate file and mount them onto the main application.

#### Create a Router

```javascript
import { Router } from "aroma.js";

const router = new Router();

router.get("/", (req, res) => {
  res.send({ message: "Hello from Router!" });
});

router.get("/:id", (req, res) => {
  res.send({ message: `User ID: ${req.params.id}` });
});

export default router;
```

#### Mount the Router

```javascript
import Aroma from "aroma.js";
import userRouter from "./routes/user";

const app = new Aroma();

// Mount the router under /users
app.use("/users", userRouter);

app.listen(3000, () => {
  console.log("Server is running on http://localhost:3000");
});
```

### Middleware

You can use custom middleware to process requests before they reach the route handlers.

```javascript
app.use((req, res, next) => {
  // Custom logic
  next();
});
```

### Sessions

Enable session management with cookies:

```javascript
app.useSessions();
```

Sessions are automatically handled, and session data is stored in memory.

### Cookies

Manage cookies:

```javascript
app.manageCookies(res, "cookieName", "cookieValue", {
  httpOnly: true,
  maxAge: 3600,
});
```

### Template Engine

Enable the template engine to render dynamic views:

```javascript
app.enableTemplateEngine();
app.render(res, "view", { data: "value" });
```

### Error Handling

Handle errors with custom error handlers:

```javascript
app.handleErrors((err, req, res) => {
  res.status(500).send("Internal Server Error");
});
```

### Example

Here is an example of using Aroma.js to create a basic application with routes, middleware, and static file serving:

```javascript
import Aroma from "aroma.js";

const app = new Aroma();

// Serve static files from 'public' directory
app.serveStatic("public");

// Middleware to log requests
app.use((req, res, next) => {
  console.log(`Received ${req.method} request to ${req.path}`);
  next();
});

// Simple route to handle GET requests to the root
app.get("/", (req, res) => {
  res.send({ message: "Welcome to Aroma.js!" });
});

// Handle errors globally
app.handleErrors((err, req, res) => {
  console.error(err);
  res.send(JSON.stringify({ error: "Internal Server Error" }));
});

// Start the server
app.listen(3000, () => {
  console.log("Aroma.js server running at http://localhost:3000");
});
```
