Time Travel Debugging: Beyond Console.log
Tools like replay.io and Firefox's DevTools let you record your application's execution and play it back later. It's like TiVo for your code!

Don't Look Down on Print Debugging
Have you ever been able to try https://replay.io time travel debugging as an alternative to conventional logging?
Last time I tried it you were able to add logging statements "after the fact" (i.e. after reproducing the bug) and see what they would have printed. I believe they also have the ability to act like a conventional debugger.
I think they're changing some aspects of their business model but the core record / replay tech is really cool.

A (Mostly) Complete Guide to React Rendering Behavior
Not at this time. I'm pretty full up at this point with day job ( https://replay.io ), conferences, and personal life stuff.
My current ongoing Redux maintenance task is trying to revamp our "Redux Essentials" tutorial to be TS-first. Making slower progress on that than I'd wanted, but hopefully can get that wrapped up in the not _too_ distant future.
Beyond that, we've got a ton of open RTK Query feature requests that I'd like to address later on this year.

Is Something Bugging You?
Exactly - that's what we've already built for web development at https://replay.io :)
I did a "Learn with Jason" show discussion that covered the concepts of Replay, how to use it, and how it works:
- https://www.learnwithjason.dev/travel-through-time-to-debug-...
Not only is the debugger itself time-traveling, but those time-travel capabilities are exposed by our backend API:
- https://static.replay.io/protocol/
Our entire debugging frontend is built on that API. We've also started to build new advanced features that leverage that API in unique ways, like our React and Redux DevTools integration and "Jump to Code" feature:

Why does the `useSyncExternalStore`docs example call `getSnapshot` 6 times on store update?

Replay.io: announcing our new Replay for Test Suites feature! Time-travel debug Cypress (and Playwright) tests in CI
Hiya folks! In addition to all my free time spent working on Redux, answering questions, and modding this sub, my day job is working on Replay.io. Today we're thrilled to announce our new Replay for Test Suites feature, which lets you record and time-travel debug Cypress (and Playwright) E2E tests as they ran in CI!
