V8 Can Not Connect To Node Js Inspector Using Websocket Stack Overflow

V8 Can Not Connect To Node Js Inspector Using Websocket Stack Overflow I am trying to develop a node.js debugger in javascript. i am executing a js script using node inspect brk like below then it prints the websocket url now i am using websocket to connect but, when i send the continue command then i get no response from v8. Embedders (including devtools) need to rely directly on the inspector protocol. this page is intended to give embedders the basic tools they need to implement debugging support in v8.

V8 Can Not Connect To Node Js Inspector Using Websocket Stack Overflow If you try to connect to node inspector ws: 127.0.0.1:9229 node, you get 400 bad request. because check } else if (!state >ws key) { handshake failed (inspector); } in the inspector socket.cc:523 failed. To support that we’ll need to extract parts of debugger and profiler functionality from blink into a separate project that would implement devtools remote debugging protocol. let’s call the project v8 inspector. node.js could then expose the protocol to the frontend over a websocket connection. Creating a websocket client now that we have a websocket server, let's create clients to connect to it. we'll create both a node.js client and a browser client. Disabling the websocket proxy route and directly exposing the nodejs machine 9229 port fixed the issue and i can now find my instance in chrome: inspect. using node 8.x.x gives the ability use the chrome devtools and that's a great help.

If someone has figured out a proper set of steps to use inspect or debug but connect via chrome, i'm happy to use it as a work around. for now we've just reverted back to 7.4.0 in the meantime. On our side we'll have to make sure that changes to v8 inspector api would be made in a non breaking manner, follow the same public api deprecation policy as v8 does and the new apis would work for node too, not only for chrome. I think jetbrains does the same thing, so webstorm and friends probably have the same issue, though i have not tested it. also, if i try to open the inspector in the test file itself, it works fine, so it seems like there might be some initialization ordering that's different for test. I'm trying to set up an ssh tunnel to a local node.js instance running in debugging mode, which listens on port 9229. the goal is to forward traffic from a remote machine to the debugging port on my local machine, as per the node.js remote debugging documentation.
