I can check what data is transferred easily. This does not happen if we have a WebSocket selected and another opened WebSocket on the same page has received a message (in the screenshot above, livereload is a websocket)Īt first I suspected that it was like some IDEs and console loggers, I'd have to enable/disable some kind of option like Scroll Lock or Show console when standard error changes, but I don't see such option on Google Chrome that would cause this.Ĭhrome Web Inspector Web Socket Debugging I can use the Network tab in the Google Chrome Web Inspector to debug the network traffic (AJAX requests, etc.). This happens on any tab of the WebSocket properties, not just the Frames tab This also happens when the network recording is turned off I'd like that to be true, but unfortunately every time I select the WebSocket resource on the left to analyze it, if that WebSocket receives a new message, the viewport switches to the closest other resource above or below it from the left pane. Main panel by clicking on entry on the left.

According to the answer at :Įvery time you send or receive new messages, you have to refresh the However I'm encountering an issue with the debugger itself. I am trying to debug an issue happening on a WebSocket, the browser (client) receiving textual JSON messages at a fast pace (no binary data), with the server not expecting any messages from the client.

WebSocket debugger in Google Chrome is “minimized” when a new message is received by the current WS I am using Google Chrome, developing an AngularJS frontend generated with yeoman and served with grunt. Not the most clear representation, but the dev tools were made to primarily deal with HTTP where individual requests don't last forever.įree ProTip in case you didn't know: If you click on any of the requests and then click on the Frames tab, you can see all the WebSocket messages in real-time. The developer tools shows each connection that hasn't been closed yet as 'pending'. The 'pending' connections are active connections. Maybe whatever library you're using likes to create multiple connections? You seem to have one closed connection and three ongoing connections. As you can see in the Status column, the server responded with '101 Switching Protocols', after which the protocol changed to the WebSocket protocol. Yes, that's because the WebSocket handshake is an HTTP GET request. One websockets was completed and the other 3 were still pending, what does this mean? Do we actually have 4 websocket connections? If we have 4 type = websocket like in this example. Is this because this HTTP protocol is used to initiate the handshake? The method still is specified with the HTTP get method verb. When we have the following output in chrome:

I have a couple of questions regarding how to interpret websockets in the chrome devtools: Websockets in chrome devtools Currently working with Socket.IO using websockets. Of course you can have more opened connections to different websockets, aggregated on the main 'Network' tab by websocket type. This change a protocol (HTTP status 101),Įvery possible next request being websocket traffic, will be visible under Frames tab of above entry. Information about this traffic is nested deeper in Network tab.Įntry about connection to the websocket, on the main Network tab listing.

You can then click on the connection to show the traffic being sent back and forth with on the server This will show you a connection being made with a websocket. You need to reload the page with the network tab open and filter by type 'ws'. Using Chrome v56, also tried Safari with no luck.ĭoes anyone know how this can be achieved? However I've been inspecting sites that I know are using websockets and can't find a way to inspect the messages being sent back and forth. From my research it seems you should be able to see it using the network tab - and it even has a filter for 'ws'. I'm trying to inspect websocket traffic using Chrome Developer Tools. How to inspect WebSocket frames in Chrome properly? How do you inspect websocket traffic with Chrome Developer Tools? - websocket This question already has an answer here:
