ReactPHP HTTP Server + Wasmer

This example shows how to run a minimalist ReactPHP HTTP server on Wasmer Edge.

Demo

app/index.php wires together ReactPHP’s event loop and HTTP server:

require __DIR__ . '/../vendor/autoload.php'; loads dependencies installed via Composer.
new React\Http\HttpServer(...) defines a callback that returns "Hello World!\n" for every request.
React\Socket\SocketServer('127.0.0.1:8080') opens a TCP socket, and HttpServer->listen($socket) attaches the HTTP handler.
When the script runs, it keeps the event loop alive and logs the listening URL.

You can extend the callback to implement more complex routing or JSON APIs.

composer install
php app/index.php

ReactPHP listens on http://127.0.0.1:8080/. Hit the URL in your browser or with curl to confirm the “Hello World!” response.

Install dependencies (composer install --no-dev --optimize-autoloader) before deploying.
Ensure your start command runs php app/index.php (or similar) so Wasmer boots the ReactPHP loop.
Visit https://<your-subdomain>.wasmer.app/ to verify the server responds.
