If I had time to get something up and running where the html could be rendered on both client and server using the same code base in the early stages of a project then I would. It all depends on the project of course but currently here is the order in which I tend to do things: 1 Write an api 2 Write web/mobile apps to consume it 3 Optimize by pre-rendering the html when needed if the project becomes popular enough or if it really needs to be crawled.
