Most of the time, web APIs are not functional requirements. They don’t add any value to the product we are building. They are just a necessary evil so the frontend can communicate with the backend. But is that really the case? Wouldn’t it be possible to get rid of these web APIs?

In response to this, Manuel built Liaison, which is still in alpha, but aims to seamlessly bridge the divide between frontend and backend without having to formalize an API between the two.

From reading the post, it appears to be akin to our old friend, RPC. If you are interested enough to dive into the code, he’s put together a RealWorld example which holds up quite well to the competition on a lines-of-code-to-implement basis.
