Overview
Show active intervals, scheduled timeouts, animation frames, idle callbacks, eval invocations, media events and properties
If you're web developer and want to assess implementation correctness - this tool adds additional panel to the browser’s DevTool that enables to see scheduled timeouts and active intervals, as well as to review and navigate to initiators of: eval, setTimeout, setInterval, requestAnimationFrame, requestIdleCallback and their terminator functions. Allows: - to measure callback execution self-time. - to see requestAnimationFrame callback request frame rate. - visit every function in the call stack (if available), bypass or pause while debugging. - detect eval function usage, see its argument and return value, same for setTimeout and setInterval when called with a string instead of a function. - for every mounted video or audio media element's to see it’s state and properties. Helps to spot: - incorrect timeout delay. - bad handler for terminator function. - terminating non existing or elapsed timeout. Motivation: - To expedite issues discovery. Wrapped native functions: - eval (by default off) - setTimeout - clearTimeout - setInterval - clearInterval - requestAnimationFrame - cancelAnimationFrame - requestIdleCallback - cancelIdleCallback Note: - while measuring performance of your code – consider disabling this extension as it may affect the results.
