Astro makes this possible. In the past, to add form processing to a static or JAMStack site, you would add serverless functions. These could run in different environments, and typically their code was segregated from the rest of your project. Hybrid rendering in Astro lets you prerender all your site pages, but include a server handler to process the form inputs. We saw an example, creating a comment form. Now your form handling code becomes a first-class in your project!
