How to test Laravel Breeze API with HTTP-only cookies from a different domain?

One possible solution is to use a proxy server to forward requests from localhost to the API domain. This way, the cookies will be sent along with the requests and the API will be able to authenticate them.

Here's an example of how to set up a proxy server using the http-proxy-middleware package:

1. Install the package:

npm install http-proxy-middleware --save-dev

1. Create a file named proxy.js in the root of your project with the following content:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(
    '/api',
    createProxyMiddleware({
      target: 'https://api.somedomain.com',
      changeOrigin: true,
      secure: false,
      cookieDomainRewrite: {
        '*': 'localhost'
      }
    })
  );
};

This will forward all requests to /api to the API domain and rewrite the cookie domain to localhost.

1. Modify your package.json file to include the following line:

"proxy": "http://localhost:3000"

This will tell your frontend application to use the proxy server when making requests to the API.

1. Start the proxy server by running the following command:

node proxy.js

1. Start your frontend application and make requests to /api as usual. The requests will be forwarded to the API domain and the cookies will be sent along with them.

Note: Make sure to remove the proxy configuration when deploying your application to production.
