DebuggerDomain

breakpointResolved

Fired when breakpoint is resolved to an actual script and location.

continueToLocation

Continues execution until specific location is reached.

disable

Disables debugger for given page.

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.

evaluateOnCallFrame

Evaluates expression on a given call frame.

events

Subscribes to all events related to this domain.

executeWasmEvaluator

Execute a Wasm Evaluator module on a given call frame.

getPossibleBreakpoints

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

getScriptSource

Returns source for the script with given id.

getStackTrace

Returns stack trace with given stackTraceId.

getWasmBytecode

This command is deprecated. Use getScriptSource instead.

pause

Stops on the next JavaScript statement.

paused

Fired when the virtual machine stopped on breakpoint or exception or any other stop criteria.

pauseOnAsyncCall

removeBreakpoint

Removes JavaScript breakpoint.

restartFrame

Restarts particular call frame from the beginning.

resume

Resumes JavaScript execution.

resumed

Fired when the virtual machine resumed execution.

scriptFailedToParse

Fired when virtual machine fails to parse the script.

scriptParsed

Fired when virtual machine parses script. This event is also fired for all known and uncollected scripts upon enabling debugger.

searchInContent

Searches for given string in script content.

setAsyncCallStackDepth

Enables or disables async call stacks tracking.

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.

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.

setBreakpoint

Sets JavaScript breakpoint at a given location.

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.

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.

setBreakpointsActive

Activates / deactivates all breakpoints on the page.

setInstrumentationBreakpoint

Sets instrumentation breakpoint.

setPauseOnExceptions

Defines pause on exceptions state. Can be set to stop on all exceptions, uncaught exceptions or no exceptions. Initial pause on exceptions state is none.

setReturnValue

Changes return value in top frame. Available only at return break position.

setScriptSource

Edits JavaScript source live.

setSkipAllPauses

Makes page not interrupt on any pauses (breakpoint, exception, dom exception etc).

setVariableValue

Changes value of variable in a callframe. Object-based scopes are not supported and must be mutated manually.

stepInto

Steps into the function call.

stepOut

Steps out of the function call.

stepOver

Steps over the statement.
