  • React

    The library for web and native user interfaces.

    • When I worked at Facebook, I worked on a web memory tracking tool I was particularly proud. It went through links, grabbed snapshots, diff'ed them, found objects that weren't clean up and gave detailed information about its retain chain. You can see a lighting talk I did on it at BlinkOn: https://www.youtube.com/watch?v=JuyaGFApifA&t=1427s&ab_chann...

    We used it to find a problem fixed in React 18 that caused large leaks on Facebook.com: https://github.com/facebook/react/pull/21039#issuecomment-80...

    We also found one issue that caused a leak that's impossible to spot unless you know how V8 closures are implemented and retain one another.

    I'm really hoping to see Facebook open source the tool some day!

    • Author here. I added support for [custom scenarios](https://github.com/nolanlawson/fuite/#extending-the-default-...), where you can define a "setup" step that logs in or does whatever you may need to do.
