caldaria utilizes Solid's blazing fast SSR capabilities while also maintaing the goodness of Single Page Applications. SolidJS offers 3 kinds of SSR: Sync, Async and Streaming, in which caldaria defaults to Async. You can pick your own SSR mode to build with using the ssrMode option for createBuild:
caldaria.createBuild({
ssrMode: 'async' // Other values: 'sync', 'node-stream', 'web-stream'
});
