React Native’s networking stack is built on native APIs:
- iOS and macOS: NSURLRequest
- Android: OkHttpClient
- Windows: winrt::Windows::Web::Http
There’s a “last mile” of non-native code to expose it as familiar JavaScript APIs, sure, but the hot path is all native.

Learning the right way to consistently vertically align text across both iOS and Android thanks to @mrtry_'s talk at React Native Japan!
The key to victory is the `includeFontPadding` style!
Also iOS doesn't have `textAlignVertical`? 😮

OSS contributions are measured in bread machines
Node & TypeScript excitement 😉
Marco tells the story of implementing Type Stripping support in Node. It involves a lot of collaboration across the JS ecosystem.
🔷 First cut took 20 days (fast for Node)
🔷 TS delivered flags to ease adoption
🔷 Marco's reward: a bread machine

If you ever feel like being truly hazed, try asking an LLM to implement streaming file uploads for the Electron main process.
It's a pinball machine that ricochets between being wrong for every possible implementation of networking that Electron has access to.

Nice! I’d say when comparing Expo / React Native to single-platform dev, some easy things become hard, yet some hard things become easy.
Personally, I greatly prefer the tradeoff that Expo / RN strikes. I like writing TS, developing in VSC and expressing UIs in React + Tailwind.

Businesses need to get into the habit of valuing engineering hours properly. Sure, CI/CD and SaaS offerings do cost a certain amount, but spending weeks of engineering time naïvely trying to implement a fraction of what something like EAS gives you is just short-sighted.
Team debated: GitHub Actions vs Jenkins for CI/CD.
Jenkins advocates:
- We already have it
- More powerful
- Self-hosted
- Free (ignoring ops time)
GitHub Actions advocates:
- YAML in repo
- No server to maintain
- Modern UI
- Faster
Decision process:
- Ran both for 1 month
- Same workflows
Results:
Jenkins:
- Maintained by 1 person (40 hours/month)
- Plugins broke after updates
- UI from 2010
- Build queue issues
GitHub Actions:
- Zero maintenance
- Just works
- Cost: $120/month
- Fast feedback
Migrated fully to GitHub Actions.
Six months later:
- That 1 person works on actual features now
- CI/CD is no longer a team discussion topic
- Onboarding new engineers: trivial

This one was tough. Lots of challenges when your node_modules itself is a symlink, and even more so for out-of-tree platforms. Got to demonstrate various Metro debugging techniques.
Was able to get something working thanks to Microsoft's rnx-kit, though!

I'll be hacking on my unreleased dev tool, React Native Fiddle tonight. Come learn advanced Metro debugging!

Today I find myself using Microsoft's rnx-cli instead of React Native Community CLI / Expo CLI, and also ended up having to write my own custom Metro reporter for it.
I'm so many side-quests deep right now, but it's all for a reason, I promise

Cloudflare has lost a lawsuit to major Japanese Companies to pay damages for hosting Anime and Manga Piracy sites up to 3.3 Million Dollars. Reminder that Cloudflare is also the company that was responsible for the internet going down a few days ago. youtu.be/x9okEMNInp8

I have created the most incredible thing but there's no point showing it yet because nobody uses Twitter on the weekend

And thanks @_neqoxec for jumping on the review! Had never known it could be so quick to get code into React Native.

To tell the truth, my "first" PR to React Native was actually in 2018, to the non-Microsoft react-native-macos project by @potomushto. But everything I've done since then has been in userland, or on community modules.
Was a great experience PRing to core!
