We have started the beta testing of the new Lightstreamer Web Client library, v. 8.1.0.
The main difference with the previous version is in the connection setup mechanism, also known as stream-sense. With version 8.1.0, instead of creating a session over HTTP and then switching to WebSocket, a session is created directly over WebSocket, while preserving the ability to fall back to HTTP. This means that in most cases, clients are able to set up the streaming channel with one connection only instead of two, reducing the session initiation time and overhead.
The new beta library is available on npm and you can test it in non-production environments.
Please get back to us for any feedback and questions.
