## Quick Usage (CLI)

You can run your applications in localhost with TypeScript support and watch mode using `listhen` CLI:

Create `index.ts`:

```ts
export default (req, res) => {
  res.end("Hello World!");
};
```

or using [unjs/h3](https://github.com/unjs/h3):

```ts
import { createApp, eventHandler } from "h3";

export const app = createApp();

app.use(
  "/",
  eventHandler(() => "Hello world!"),
);
```

or use npx to invoke `listhen` command:

```sh
npx listhen -w ./index.ts
```

## Usage (API)

Install package:

```bash
# pnpm
pnpm i listhen

# npm
npm i listhen

# yarn
yarn add listhen

```

Import into your Node.js project:

```js
// CommonJS
const { listen, listenAndWatch } = require("listhen");

// ESM
import { listen, listenAndWatch } from "listhen";
```

```ts
const handler = (req, res) => {
  res.end("Hi!")
}

// listener: { url, getURL, server, close, ... }
const listener = await listen(handler, options)
```

## Options

### `port`

- Default: `process.env.PORT` or 3000 or memorized random (see [get-port-please](https://github.com/unjs/get-port-please))

Port to listen.

### `hostname`

- Default: `process.env.HOST || '0.0.0.0'`

Default hostname to listen.

### `https`

- Type: Boolean | Object
- Default: `false`

Listen on HTTPS with SSL enabled.

#### Self-Signed Certificate

By setting `https: true`, listhen will use an auto-generated self-signed certificate.

You can set https to an object for custom options. Possible options:

- `domains`: (Array) Default is `['localhost', '127.0.0.1', '::1']`.
- `validityDays`: (Number) Default is `1`.

#### User-Provided Certificate

Set `https: { cert, key }` where the cert and key are paths to the SSL certificates.
With an encrypted private key, you also need to set `passphrase` on the `https` object.

To provide a certificate stored in a keystore set `https: { pfx }` with a path to the keystore.
When the keystore is password protected also set `passphrase`.

You can also provide an inline cert and key instead of reading from the filesystem. In this case, they should start with `--`.

### `showURL`

- Default: `true` (force disabled on a test environment)

Show a CLI message for the listening URL.

### `baseURL`

- Default: `/`

### `open`

- Default: `false` (force disabled on test and production environments)

Open the URL in the browser. Silently ignores errors.

### `clipboard`

- Default: `false` (force disabled on test and production environments)

Copy the URL to the clipboard. Silently ignores errors.

### `isTest`

- Default: `process.env.NODE_ENV === 'test'`

Detect if running in a test environment to disable some features.

### `autoClose`

- Default: `true`

Automatically close when an `exit` event, `SIGTERM`, `SIGINT` or `SIGHUP` signal is received in the process.

### `publicURL`

- Default: (the first public URL listening)

The public URL to show in the CLI output

### `qr`

- Default: `true`

Print QR Code for public address.

### `public`

- Default: `false` for development or when `hostname` is `localhost` and `true` for production

When enabled, listhen tries to listen to all network interfaces. You can also enable this option using `--host` CLI flag.

### `ws`

- Default: `false`

Enable experimental WebSocket support using [unjs/crossws](https://crossws.unjs.io/) or node upgrade handler.

Option can be a function for Node.js `upgrade` handler (`(req, head) => void`) or an Object to use [CrossWS Hooks](https://crossws.unjs.io/guide/api).

When using dev server CLI, you can easily use `--ws` and a named export called `websocket` to define [CrossWS Hooks](https://github.com/unjs/crossws) with HMR support!
