The Laravel framework version 7 and above includes first-party support for sending CORS headers using Middlewares. A simple Vue.js app powered by Laravel is used to learn about CORS, with a focus on configuration options such as paths, allowed methods, origins, headers, exposed headers, max age, and credential support. The tutorial covers how to set up the Laravel API and frontend, and how to make HTTP requests from the frontend to the backend while logging response headers. It also discusses enabling CORS for a route prefix, looking up allowed HTTP methods, restricting allowed hosts, configuring allowed headers, exposing custom headers, caching CORS responses, and HTTP sessions over CORS. The tutorial concludes by highlighting the security issues around misconfiguring CORS and providing resources for further learning.
