Request handler

import route from '@clappcodes/transporter/route';
import { BroadcastStream, transform } from '@clappcodes/transporter/stream';

const toUpperCase = route.post('/toUpperCase', ({ request }) =>
  request.body
    ?.pipeThrough(new TextDecoderStream())
    .pipeThrough(transform.toUpperCase())
    .pipeThrough(new TextEncoderStream()));

const echo = route.post('/echo', (ctx) => {
  const stream = new BroadcastStream();

  ctx.request.body?.pipeTo(stream.writable);
  ctx.headers.set('content-type', 'text/event-stream');

  return stream.readable;
});

route(route.cors(), echo, toUpperCase)
  .serve({ port: 3000 });

Quick start

• Just paste in console

import('https://esm.sh/@clappcodes/transporter/stream')
  .then(({ transport, transform }) =>
    transport.pipe(
      transport.text(`https://transporter.deno.dev/toUpperCase`),
      transport.text(`https://transporter.deno.dev/echo`),
      transform.toUpperCase(),
    )
  )
  .then((stream) => {
    stream.read(console.log);
    stream.write('Hello World');
  });

import { transport } from "@clappcodes/transporter/stream";

const stream = transport.pipe(
  transport.text("/toUpperCase", /** toUpperCase */)
  transport.text("/echo", /** echo */)
);

stream.read(console.log);
stream.write("Hello"); // => HELLO
