Pure Node.js echo server, that logs all incoming http requests (method, path, headers, body).

echo.js

const http = require('http');
const server = http.createServer();

server.on('request', (request, response) => {
    let body = [];
    request.on('data', (chunk) => {
        body.push(chunk);
    }).on('end', () => {
        body = Buffer.concat(body).toString();

	console.log(`==== ${request.method} ${request.url}`);
	console.log('> Headers');
        console.log(request.headers);

	console.log('> Body');
	console.log(body);
        response.end();
    });
}).listen(8083);

The oneliner version, just copy past in your terminal:

node -e "const h = require('http');const s = h.createServer();const l = console.log;s.on('request', (rq, rs) => {let b = [];rq.on('data', (c) => {b.push(c);}).on('end', () => {b = Buffer.concat(b).toString();l('==== '+rq.method+' '+rq.url);l('> Headers');l(rq.headers);l('> Body');l(b);rs.end();});}).listen(8000);"
