Single Page App Back Ends: Where Laravel Beats Node.js

Node's bigger advantage over PHP is allowing a single product to use a single language, even if the code bases are divided between the front-end and back-end.
For serverless NodeJS, zeit now might be worth considering as an alternative to AWS's lambda.
I would say Laravel doesn't beat NodeJS for SPA at all, because with Nuxt+Vuejs or Next+React, you can write your templates once and render with both the server on first arrival and with the client on subsequent arrivals. Then that setup can defer business logic to any one or more JSON backends (Laravel, nodejs, golang, etc.).
That isn't serverless because the server is still running even when the PHP code isn't responding to a request.
