Who said React Native is slower than "native"? 🤔❌ Left: Native (by @Google) Right: React Native (our client @humandco)

Shoutout to @plahteenlahti for a fantastic talk about how the news of the demise of React Native at the hands of AI is premature #appjsconf @RevenueCat

Wife: “ugh. This app is so bad. The cross-platform experience is awful” Me: turned on.

I don’t know who needs to hear this but *pinch* of baking soda stops almond milk from curdling in coffee. It brings down the acidity that curdles the milk.

SECURITY ADVISORY — TanStack npm packages A supply-chain compromise affecting 42 @tanstack/* packages (84 versions total) was published to npm earlier today at approximately 19:20 and 19:26 UTC. Two malicious versions per package. Status: ACTIVE — packages are deprecated, npm security engaged, publish path being shut down. Severity: HIGH — payload exfiltrates AWS, GCP, Kubernetes, and Vault credentials, GitHub tokens, .npmrc contents, and SSH keys. If you installed any @tanstack/* package between 19:20 and 19:30 UTC today, treat the host as potentially compromised: • Rotate cloud, GitHub, and SSH credentials immediately • Audit cloud audit logs for the last several hours • Pin to a prior known-good version and reinstall from a clean lockfile Detection — the malicious manifest contains: "optionalDependencies": { "@tanstack/setup": "github:tanstack/router#79ac49ee..." } Any version with this entry is compromised. The payload is delivered via a git-resolved optionalDependency whose prepare script runs router_init.js (~2.3 MB, smuggled into each tarball at the package root). Unpublish is blocked by npm policy for most affected packages due to existing third-party dependents. All 84 versions are being deprecated with a SECURITY warning, and npm security has been engaged to pull tarballs at the registry level. Full technical breakdown, complete package and version list, and rolling status updates: github.com/TanStack/router/i… Credit to the security researcher for responsible disclosure.

if you're in or near prague, check out the @expo x @strvcom hackathon this friday (may 1)! 💡 the idea: pick a business that you care about that either doesn't have an app or whose app desperately needs to be replaced, then build the best app you can in a day. 🏆 prizes: 10k in expo credits! tickets to app.js conf! get featured on expo blog and socials. and more. 🤷‍♂️ folks from our team (@sethwebster @davidmokos_ Adam Zvada and @joe_d_ryan) will be on site to help out!

As I shared in my talk yesterday at @ReactMiamiConf only short-sighted leaders are laying off staff for efficiency gains at this point. 🤖 will drive a natural correction but layoffs en masse signal missing the true opportunity: do way more with way more.

Seth is different. He can zoom way out and see all the layers all the way through a product/business/team. He knows what to say. And what to build. And how to build it. What's possibly most impressive is that he delivers all this perspective with warmth and joy. It's infectious. We're lucky to have him. His note about this decision to join Expo will give you a small, delightful sample of what it's like to work with him ↓
