now-sapper

Your Sapper project must be adapted to work with Zeit Now v2, see https://github.com/thgh/sapper-template/commit/220307c800525633063df3e3373bc76d0e62cd86

For Express, the instance must be exported in src/server.js

const app = express()
export default app

For Polka, the handler must be exported in src/server.js

const app = polka()
export default app.handler

Example now.json

{
  "version": 2,
  "builds": [
    {
      "src": "__sapper__/build/index.js",
      "use": "now-sapper"
    }
  ],
  "routes": [{ "src": "/(.*)", "dest": "__sapper__/build/index.js" }]
}
