The best part of building in open source is real devs coming back with "this works" 🥹
rn-build-doctor is helping people get past React Native and Expo build failures, and the feedback keeps me going.

I built an open-source CLI tool called RN Build Doctor to help diagnose build failures and crashes using project configuration and build logs.
If you're still running into similar issues, I'd love for you to give it a try and share feedback on whether its diagnosis is useful.

0.1.7 of rn-build-doctor is out!!
I spent the weekend reading GitHub issues from the week after Expo SDK 58 and RN 0.88, and reproduced each failure on a real AGP 9.2.1 build before changing anything.
Library AAR metadata failures no longer tell you to raise your app's compileSdk. It names the npm package actually causing it.
AGP 9 dependencies with no version now get the real explanation and a one-line fix I verified on the broken build.
Xcode 27's deployment target error for old pods is finally caught, with the pod name and the Podfile workaround.
Every fix in this release started as someone's worst build day.

Today is the day to fold your apps 🙌
We wrote a guide you can give to your agents to get started.
On iPhone Duo your status bar and tab bar move into a rail on the side, so 𝚒𝚗𝚜𝚎𝚝𝚜.𝚝𝚘𝚙 is 0 now. This guide from @huntie, @__ubax__, and @chrfalch will help you adjust your apps for the fold:

A week ago I shipped a small tool for something that kept eating my evenings: scrolling through React Native build logs to find the one line that actually broke.
rn-build-doctor crossed 250+ downloads in its first week.

Datadog shipped an agent that you just tell "book a round trip flight" and it figures out the clicks itself and keeps testing it.
If this actually works I’m never writing a selector again.

Learning a new tool always goes the same way. At first it changes everything, then nothing works, then I realise it was my config all along. A week later I'm writing a thread about it.

Ravana had 10 heads. My codebase has:
- A ‘quick fix’ from 2022
- Tests that pass on retry
- 47 deps, 12 actually used
- console.log(‘here 2’)
- // TODO: fix later
- catch (e) {}
- if (status === 3)
- utils.js, utils2.js, utilsNew.js
- : any
- A function nobody touches because ‘it works’
Today we burn them all 🔥
Happy Dussehra! 🏹

A checklist for reviewing AI-written PRs:
1. Read the tests first. Do they test behaviour or mirror code?
2. Look for new deps nobody asked for
3. Check every catch block. AI loves swallowing errors
4. Run it on a real device, not just CI
What would you add?

Seasons change and weeks are completely human made,
But the day has rhythm.
The sun goes up, the sun goes down.
And that's something I can handle.
We wrote a walkthrough for 𝚎𝚡𝚙𝚘-𝚊𝚙𝚙-𝚒𝚗𝚝𝚎𝚗𝚝𝚜. It starts with a counter you can bump from Siri and ends with mail drafts that show up in Spotlight: expo.dev/blog/introducing-ex…
