CORS

[juanbautista0]

in the constructor of the React\Http\Message\Response object can CORS be enabled?

Excellent question! CORS headers are supported just like any other response headers.

$app->get('/user', function () {
    return new React\Http\Message\Response(
        200,
        [
            'Content-Type' => 'text/plain; charset=utf-8',
            'Access-Control-Allow-Origin' => '*'
        ],
        "Hello wörld"
    );
});

See https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS and https://framework-x.org/docs/api/response/#headers.

Depending on your use case, you may add these headers for each route or use a middleware implementation that can be reused for a number of routes.
