* wip: working on rrweb logger
* wip: can record and replay some simple log
* wip: can record and replay log's stack
* wip: try to serialize object
* wip: record and replay console logger
hijack all of the console functions.
add listener to thrown errors
* wip: record and replay console logger
add limit to the max number of log records
* feat: enable rrweb to record and replay log messages in console
this is the implementation of new feature request(issue #234)
here are a few points of description.
1. users need to set recordLog option in rrweb.record's parameter to record log messages. The log recorder is off by default.
2. support recording and replaying all kinds of console functions. But the reliability of them should be tested more
3. the stringify function in stringify.ts needs improvement. e.g. robustness, handler for cyclical structures and better support for more kinds of object
4. we can replay the log messages in a simulated html console like LogRocket by implementing the interface "ReplayLogger" in the future
* improve: the stringify function
1. handle cyclical structures
2. add stringify option to limit the length of result
3. handle function type
* refactor: simplify the type definition of ReplayLogger
* fix: elements would lose some state like scroll position because of "virtual parent" optimization
* refactor: the bugfix code
bug: elements would lose some state like scroll position because of "virtual parent" optimization
* fix: an error occured at applyMutation(remove nodes part)
error message:
Uncaught (in promise) DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node
* Move mutation processing into it's own object.
This should stand on it's own as a refactor, but is intended as a basis
for exposing the new MutationBuffer object to further outside control e.g.
to 'mute' or batch up mutation emission when the page becomes inactive
from a https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API
point of view
* The `processMutations` function needed to be bound to the `mutationBuffer` object, as otherwise `this` referred to the `MutationObserver` object itself
* Neglected to add this output of `npm run typings`
* Get around the binding problem by using Arrow function expressions
* Prettier formatting
* introduce pako and add general packer interface
* add tests for packer
* use function API instead of class API for better tree shaking support
* refcatoring the rollup bundle config
1. add a liveMode flag to config, when liveMode is set, the timer
will keep running even though all the actions casted
2. add a public method addEvent, which will cast newly added event
in sync
3. move mouse in sync mode with the latest position info
