The createHandler is used to start the server in entry-server.tsx. It takes a function that returns a static document (often created with <StartServer>), and serves it using one of the three function for server side rendering (SSR):

• renderToString - "sync"
• renderToStringAsync - "async"
• renderToStream - "stream"

The SSR mode can be configured through the mode property on the options object:

import { createHandler, StartServer } from "@solidjs/start/server";
export default createHandler(() => (
  <StartServer document={...}
  />
), {
  mode: "async"
});
