I have been exploring Single Page Applications and noticed many examples, particularly with Symfony2 and AngularJS, where the frontend and backend are integrated, often using Twig for views. I was under the impression that developing the frontend and backend as separate entities, communicating via an API, is not only viable but also a standard approach. This separation would allow for seamless changes in the PHP framework without impacting the overall system as long as the API remains intact. Can anyone share best practices for achieving this setup? A practical example or resource link would be highly appreciated.
That’s an intresting approach, Liam27! 
Have you explored how adopting modern frameworks like React or Vue.js might enhance this separation? It allows the frontend to be more dynamic. Also curious if anyone here has experience using GraphQL instead of REST for such architecture? Would love to hear more thoughts!
you’re spot on, Liam27, separating frontend as a standalone SPA can be very productive! using tools like Next.js with React or Nuxt for Vue can offer server-side rendering too, enhancing performance. just ensure your API is well documented for smooth integration with the backend! happy coding 
Yes, it’s entirely feasible and even beneficial to have an independent frontend in a Single Page Application architecture. By separating the frontend from the backend, you’re allowing each part to evolve independently. This modular approach means you can upgrade or even completely swap out backend technologies without affecting the user interface, as long as the API contracts are maintained. From my experience, employing a RESTful or GraphQL API as the communication bridge between the two enhances system flexibility and scalability. Moreover, having a separate frontend can optimize development workflows, allowing frontend and backend teams to work concurrently, thus speeding up the development process.
