Finally at @appjsconf — Charlie’s keynote on why @expo and React Native are winning

[Seth Webster @sethwebster]

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

[Seth Webster @sethwebster]

Yeah @jmeistrich — you nailed it.

[Seth Webster @sethwebster]

@aurorascharff Yes! I love the click + drag

[Seth Webster @sethwebster]

From @aurorascharff, ClickLight is awesome.

Super cool -- even when not presenting -- to have a nice visual on where your mouse is and it's just fun besides.

Love it!

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:

Bring it on in!

[brent @notbrent]

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!

@GroundControl @ReactMiamiConf Agree @GroundControl !

[Seth Webster @sethwebster]

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 Webster @sethwebster]

@jmeistrich @whiskeywebfm @ReactMiamiConf The @clerk shirts are next level.

[Seth Webster @sethwebster]

@DavidKPiano @ReactMiamiConf @jen_ayy_ Winner of best hair contest. Also cuteness contest. The baby is cute too.

[Seth Webster @sethwebster]

Congrats to the team behind @ReactMiamiConf (esp. @MichelleBakels) for putting on such an amazing event.

Amazing to be in a room with so many extraordinary builders. Finally got here and got to meet @gabegreenberg!
