@dcolascione @victormustar You can not. It can only be sent in headers to specific domains that are in the allow list for the given env.

@DavidSherret @elvecent_not @liran_tal @deno_land And for every fetched source file, the hash is in the meta file (so you can verify those using that hash)
@liran_tal @deno_land I honestly find it rude that you think we are this stupid. The secret is not inside the VM. It is injected using a MitM proxy that sits outside the VM based on the SNI of the outgoing request Also it takes literally 30 seconds for you to verify whether this works before tweeting
@aloo @rough__sea Yes, that's the plan
I am very proud of the team for the runtime level mitigation we rolled out to @deno_land Deploy for this. It's very precise, very fast, and way less prone to false positives than a WAF based block. All React reversions are safe when running on Deno Deploy. Vertical integration!
There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it. A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately. react.dev/blog/2025/12/0…
@MFrancis107 @deno_land That's odd - `deno run --tunnel` uses QUIC. Can you figure out whether your network is blocking that somehow? One thing you can try is going to http3.is and then reloading after first load.
@MFrancis107 @deno_land Are you behind some corporate proxy? If you visit deno.com, what TLS certificate do you get served?
@MFrancis107 @deno_land That works!
@katsuba_igor @deno_land @mastra @langfuse That already works. Instructions are on this page (see otel endpoint section) langfuse.com/docs/opentelem…
@zkochan @pnpmjs @deno_land I already commented on it in a couple of places 👍 (I work on JSR at Deno)
@slicknet What specifically isn’t working for you? We are standardizing the behavior in WinterTC right now - would you like to join the calls?
Luca Casonato 🏳️🌈 retweeted
We've published our official JavaScript SDK on @jsr_io. In Deno, we can use web standard interfaces like WebSocket on the server, as in this example with the Realtime API. Let us know what you think! 🦕
The @OpenAI JavaScript SDK is now on @jsr_io 🎉️ deno.com/blog/openai-on…
Full transparency: someone from both @ncsc_nl and the incident response team from @Logius_minbzk reached out to me and are working on resolution. The system does work after all - report issues folks! And thanks folks :)
I sent a CVD report to @ncsc_nl's CERT, and they are being wholly unhelpful. Do I know anyone that works on DigiD or other cyber security stuff at @Rijksoverheid? Is there a report channel for DigiD directly that bypasses NCSC?
@initjean @ncsc_nl @Rijksoverheid @0xDUDE @DIVDnl Oh journalists would be great - can you dm me their names?

@kettanaito @okikio_dev Undici does not support the “pass a generator function” thing. It honestly doesn’t even make sense - just invoke it and you have a async iterable?
Luca Casonato 🏳️🌈 retweeted
It's done. Now it’s your turn, @Oracle. We’ve submitted a formal petition to cancel the JavaScript trademark: it is generic, Oracle has abandoned it, and Oracle committed fraud on the USPTO during the last trademark renewal. Oracle has until January 4th to respond, or the case will go into default, which will result in the trademark being canceled. It's time to #FreeJavaScript. deno.com/blog/deno-v-or…
@dunkbingg @deno_land Is your CI job using Deno 1 or Deno 2?
