DisassembleWasmModule

DisassembleWasmModuleParams

Enable

Enables debugger for the given page. Clients should not assume that the debugging has been enabled until the result for this command is received. enable

EvaluateOnCallFrame

Evaluates expression on a given call frame. evaluateOnCallFrame

EvaluateOnCallFrameParams

GetPossibleBreakpoints

Returns possible locations for breakpoint. scriptId in start and end range locations should be the same. getPossibleBreakpoints

GetPossibleBreakpointsParams

Returns possible locations for breakpoint. scriptId in start and end range locations should be the same. getPossibleBreakpoints

GetScriptSource

Returns source for the script with given id. getScriptSource

GetScriptSourceParams

Returns source for the script with given id. getScriptSource

GetStackTrace

Returns stack trace with given stackTraceId. getStackTrace

GetStackTraceParams

Returns stack trace with given stackTraceId. getStackTrace

NextWasmDisassemblyChunk

Disassemble the next chunk of lines for the module corresponding to the stream. If disassembly is complete, this API will invalidate the streamId and return an empty chunk. Any subsequent calls for the now invalid stream will return errors. nextWasmDisassemblyChunk

NextWasmDisassemblyChunkParams

Disassemble the next chunk of lines for the module corresponding to the stream. If disassembly is complete, this API will invalidate the streamId and return an empty chunk. Any subsequent calls for the now invalid stream will return errors. nextWasmDisassemblyChunk

Pause

Stops on the next JavaScript statement. pause

PauseParams

Stops on the next JavaScript statement. pause

RemoveBreakpoint

Removes JavaScript breakpoint. removeBreakpoint

RemoveBreakpointParams

Removes JavaScript breakpoint. removeBreakpoint

RestartFrame

Restarts particular call frame from the beginning. The old, deprecated behavior of restartFrame is to stay paused and allow further CDP commands after a restart was scheduled. This can cause problems with restarting, so we now continue execution immediatly after it has been scheduled until we reach the beginning of the restarted frame.

Resume

Resumes JavaScript execution. resume

ResumeParams

Resumes JavaScript execution. resume

SearchInContent

Searches for given string in script content. searchInContent

SearchInContentParams

Searches for given string in script content. searchInContent

SetAsyncCallStackDepth

Enables or disables async call stacks tracking. setAsyncCallStackDepth

SetAsyncCallStackDepthParams

Enables or disables async call stacks tracking. setAsyncCallStackDepth

SetBlackboxExecutionContexts

Replace previous blackbox execution contexts with passed ones. Forces backend to skip stepping/pausing in scripts in these execution contexts. VM will try to leave blackboxed script by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. setBlackboxExecutionContexts

SetBlackboxExecutionContextsParams

Replace previous blackbox execution contexts with passed ones. Forces backend to skip stepping/pausing in scripts in these execution contexts. VM will try to leave blackboxed script by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. setBlackboxExecutionContexts

SetBlackboxPatterns

Replace previous blackbox patterns with passed ones. Forces backend to skip stepping/pausing in scripts with url matching one of the patterns. VM will try to leave blackboxed script by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. setBlackboxPatterns

SetBlackboxPatternsParams

Replace previous blackbox patterns with passed ones. Forces backend to skip stepping/pausing in scripts with url matching one of the patterns. VM will try to leave blackboxed script by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. setBlackboxPatterns

SetBlackboxedRanges

Makes backend skip steps in the script in blackboxed ranges. VM will try leave blacklisted scripts by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. Positions array contains positions where blackbox state is changed. First interval isn’t blackboxed. Array should be sorted. setBlackboxedRanges

SetBlackboxedRangesParams

Makes backend skip steps in the script in blackboxed ranges. VM will try leave blacklisted scripts by performing ‘step in’ several times, finally resorting to ‘step out’ if unsuccessful. Positions array contains positions where blackbox state is changed. First interval isn’t blackboxed. Array should be sorted. setBlackboxedRanges

SetBreakpoint

Sets JavaScript breakpoint at a given location. setBreakpoint

SetBreakpointByUrl

Sets JavaScript breakpoint at given location specified either by URL or URL regex. Once this command is issued, all existing parsed scripts will have breakpoints resolved and returned in locations property. Further matching script parsing will result in subsequent breakpointResolved events issued. This logical breakpoint will survive page reloads. setBreakpointByUrl

SetBreakpointByUrlParams

Sets JavaScript breakpoint at given location specified either by URL or URL regex. Once this command is issued, all existing parsed scripts will have breakpoints resolved and returned in locations property. Further matching script parsing will result in subsequent breakpointResolved events issued. This logical breakpoint will survive page reloads. setBreakpointByUrl

SetBreakpointOnFunctionCall

Sets JavaScript breakpoint before each call to the given function. If another function was created from the same source as a given one, calling it will also trigger the breakpoint. setBreakpointOnFunctionCall

SetBreakpointOnFunctionCallParams

Sets JavaScript breakpoint before each call to the given function. If another function was created from the same source as a given one, calling it will also trigger the breakpoint. setBreakpointOnFunctionCall

SetBreakpointParams

Sets JavaScript breakpoint at a given location. setBreakpoint

SetBreakpointsActive

SetBreakpointsActiveParams

Activates / deactivates all breakpoints on the page. setBreakpointsActive

SetInstrumentationBreakpoint
