I haven't found languages that let you be lazy (looking at you javascript) to be maintainable long term as a server, especially as a companion to a SPA. The complexity of maintaining a SPA is high enough as is. Having things like stronger typing and more enforced patterns on the server help keep it organized over time, where having looser more flexible patterns always leads to a spaghetti server. With a SPA, you really do need as organized of a server as possible.
