Super fast, zero configuration command line HTTP Server written in Crystal programming language.

## Features

- **Zero config** — Run and go, defaults to port 3000
- **Static file serving** — Serves files from current directory or specified path
- **Index redirect** — Automatically redirects `/blog` and `/blog/` to `/blog/index.html`
- **Directory listing** — Browse directories in browser (can be disabled with `-l no`)
- **High performance** — ~25K requests/sec (see benchmarks below)

## Usage

Zero configuration: `fast-http-server` and your server's ready.

```
usage: fast-http-server [-h] [-d DIR] [port]

positional arguments:
    port                             specify alternate port [default: 3000]

optional arguments:
    -h, --help                       show this help message and exit
    -d DIR, --directory DIR          specify a directory
    -l LIST, --listdir LIST          enable/disable directory listing (yes/no)
```

By default fast-http-server listens on port 3000. Go to `localhost:3000`.

**Examples:**

```bash
# Different port
fast-http-server 5050

# Specific directory
fast-http-server -d example_directory

# Disable directory listing
fast-http-server -l no -d ./public
```
