When you build a GraphQL server, you’re creating a system that outputs page-specific endpoints. They can be generated just-in-time (the default) or at build time (the general recommendation).

The engineering work involved shifts from building individual endpoints to building the endpoint factory. This shift may or may not be worth the trade off, but there are definite advantages, especially from the perspective of whomever is building the client. And once you factor in the ease at which you can introduce partial streaming with defer and streamable (granted they’re still WIP spec-wise), the experience can be pretty sublime.
