This is a simple HTTP server. Not support HTTP request body.

import getopts from 'tjs:getopts';
import { addr } from './utils.js';

function parseRequestLine(requestLine) {
    const [method, path] = requestLine.split(' ');
    return { method, path };
}

async function handleConnection(conn) {
    const buf = new Uint8Array(65536);
    let len = 0

    while (true) {
        const nread = await conn.read(buf);
        len += (nread || 0);
        const requestData = new TextDecoder().decode(buf.subarray(0, len));
        if (requestData.includes('\r\n\r\n')) {
            const [requestLine, ...headersLines] = requestData.split('\r\n');
            const { method, path } = parseRequestLine(requestLine);
            const headers = Object.fromEntries(headersLines.map(line => line.split(': ', 2)));
            
            const request = `Method: ${method}\nPath: ${path}\nHeaders: ${JSON.stringify(headers, null, 2)}`;
            console.log('Received request:');
            console.log(request);

            const response = `HTTP/1.1 200 OK\r\nContent - Type: text/html\r\n\r\n<html><body><pre>${request}</pre></body></html>`;
            conn.write((new TextEncoder().encode(response)));
            conn.close();
            break;
        }
    }
}

const options = getopts(tjs.args.slice(2), {
    alias: {
        listen: 'l',
        port: 'p'
    },
    default: {
        listen: '127.0.0.1',
        port: 1234
    }
});

const l = await tjs.listen('tcp', options.listen, options.port);

console.log(`Listening on http://${addr(l.localAddress)}`);

for await (let conn of l) {
    handleConnection(conn);
    conn = undefined;
}
