Request handler signature

[lucacasonato]

• Request and Response objects from WHATWG Fetch

• This means that body is ReadableStream from WHATWG Streams

• The request object should be an extension of Request as IncomingRequest:

  • req.connection
    • .protocolVersion (0.9/1/1.1/2/3)
    • .transport (tcp/unix/udp)
    • .remoteAddr
      • On unix: .path
      • On tcp: .family, .ip, and .port
      • On udp: .family, .ip, and .port
    • .localAddr (same as .remoteAddr)
    • .tls
      • .cipher
      • .peerCertificate
      • .version
      • .sni
      • Possibly other data should be exposed. Needs investigation - what do existing runtimes expose?

• Lifecycle of request / response data

  • How long can you read requests / response bodies
  • Can header access throw at some point
