PACKETSTREAM API CODE

You would probably set up the flow similar to the code below, and since you await the result of the process() call, you should be good, right? // A heavy data crunching operation.Ĭonsole. Let's assume you had an application that needs to perform heavy data crunching operations whenever a new message is received. With the current WebSocket API, reacting to a message happens in WebSocket.onmessage, an EventHandler called when a message is received from the server. The Problem with the current WebSocket API # Applying backpressure to received messages is impossible # When the stream itself or a stream later in the pipe chain is still busy and isn't yet ready to accept more chunks, it sends a signal backwards through the chain to slow delivery as appropriate. This is the process by which a single stream or a pipe chain regulates the speed of reading or writing. An important concept in the context of streams is backpressure. The Streams API allows JavaScript to programmatically access streams of data chunks received over the network and process them as desired. With this API, you can send messages to a server and receive event-driven responses without polling the server for a reply. The WebSocket API provides a JavaScript interface to the WebSocket protocol, which makes it possible to open a two-way interactive communication session between the user's browser and a server.
