A very simple cookie based session handler for dart Shelf middleware.

Here is an example of usage (see example/session_example.dart)

    // simple handler that increments a counter stored in the session
      shelf.Response pingHandler(shelf.Request request) {
        // session() function gets a reference to the session map
        var map = session(request);
        var c = map['counter'];
        int counter = ( c == null ? 0 : c) +1;
        //store counter in the session
        map['counter'] = counter;
        return new shelf.Response.ok("ping counter=$counter");
      var handler = const shelf.Pipeline()
          .addMiddleware(sessionMiddleware(new SimpleSessionStore()))
      // listen on port 7001
      io.serve(handler, InternetAddress.ANY_IP_V4, 7001);


This is super simple, and there are lots of enhancements that should be made:

  • The session maintenance / timeout code is not efficient
  • This wont work in a multi-isolate environment (needs some of way of sharing session data between isolates)
  • When Shelf gets proper cookie handling, the cookie code in here should be replaced
  • Tests. Could use some
  • Implement session data encryption
