replayable debugfriendly user sessionseach slack bug notification includes a link to a replayable user session. the session shows the record of 1) how user interacted with the web page, and 2) how the code was running on the end user machine.
this is the same information that is available in the web browser developer's tools. kuoll is like a time machine which allows the developer to see and investigate what went wrong on the user machine at the moment when a problem occured.
core technology
kuoll javascript code records debuggable user sessions and monitors a web application. when kuoll code detects javascript errors or a server xhr error replies, it uploads debugfriendly user session to kuoll server.
kuoll sends a slack notification whenever it identifies a novel issue. the dashboard displays instance count of unique errors and the number of users affected by each.
each user session contains
user events, replayable dommutations, network requests (with a complete headers and content), javascript execution flow, including calls and callbacks of promise, settimeout, setinterval methods.
all events are connected to causeeffect chains, eliminating the need for the developer to reproduce bugs. causeeffect chains provide all information necessary to analyze bugs directly in the record and to address them extremely efficiently.
the highly optimized library of clientside javascript code is at the core of kuoll’s industrybest recording script.
