How to make Chrome Dev Tools show the JavaScript source

manpreet Best Answer 2 years ago

I slightly modified the hello-world.cc sample, importing some code from d8. Then, using websocketpp and asio, I added a WebSocket Server to the program. Also, I used V8 inspector from an embedder standpoint to add a simple implementation for the inspector protocol back-end.

Now, when I start my program and then use Chrome to navigate to chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:9002, I receive the following messages from the CDT:

{"id":1,"method":"Profiler.enable"}

for witch the response is:

{"id":1,"result":{}} 

then

{"id":2,"method":"Runtime.enable"}

for this one a notification and a response are sent:

{"method":"Runtime.executionContextCreated",
 "params":{"context":{"id":1,"origin":"","name":"MyApplication"}}}

{"id":2,"result":{}}

then:

{"id":3,"method":"Debugger.enable"}

again, a notification and a response sent back to the front-end:

{"method":"Debugger.scriptParsed",
 "params":{
  "scriptId":"4","url":"func_add.js","startLine":0,
  "startColumn":0,"endLine":0,"endColumn":35,
  "executionContextId":1,"hash":"365568ee6245be1376631dbf20e7de9d42c9adf1",
  "isLiveEdit":false,"sourceMapURL":"","hasSourceURL":false,
  "isModule":false,"length":35
  }
}

{"id":3,"result":{"debuggerId":"(DC239109305DBEF825A955524584A826)"}}

For the moment, I will not add to the question the other messages received from the front-end, and the responses sent. The last exchange is:

    {"id":7,"method":"Runtime.runIfWaitingForDebugger"}
    {"id":7,"result":{}}     

My problem: in CDT, the Sources tab is empty (and therefore, I can't try to put a breakpoint).

My code to inject JS in V8:

const char * pszScript = "function add( a, b) { return a+b; }";
v8::Local<v8::String> source =
  v8::String::NewFromUtf8(isolate, pszScript, v8::NewStringType::kNormal).ToLocalChecked
                                                

                                                                                                        REPLY
                                                    
                                                
                                                


                                                    

                                                        
                                                            0
                                                            views 

                                                            0
                                                                likes 
                                                            
                                                            

                                                            0
                                                            shares
