Harness isn't a simple tool - it's a bunch of components working together to give the best DX for testing JS code with native modules. Maintaining all that as a solo dev isn't easy, so I tried offloading some work by using Jest's CLI to run Harness… and it worked!

Let me paint you a picture: It’s Friday, 2pm. You’re wrapping up a PR with important bugfixes. “It’s only 2pm and I’m almost done! This is going to be a great day!” You commit, push and go grab a coffee, because you know the build will take a half an hour at least.

Episode 2 of React Native Optimization in Practice is here 🎬 This time, @thymikee.bsky.social‬ covers another common pitfall: using web polyfills in React Native when you don’t need them. The fix? Use dedicated SDKs built for mobile. Here's why 👇 youtu.be/_Yo1kHz7h_I
