A Secure Runtime for JavaScript and TypeScript Built with V8, Rust, and Tokio

As a contributor to Deno, I am actually quite surprised that this got resurfaced on Hacker news after the hype June last year.<p>That being said, I suggest checking out this video (recorded this April) for updated information about Deno, since things have changed quite a bit since the initial announcement: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;z6JRlx5NC9E" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;z6JRlx5NC9E</a><p>(Edit: fixed link, posted the wrong one. Why would YouTube think I want to share ads...)

As a long time Node.js developer I took a look at the project but it&#x27;s still a really half-baked implementation of the security flags. You almost always end up flipping all security switches off because your application needs every feature (network, filesystem, etc).<p>No package signing, no flags per module, no syscall whitelisting, etc.

For the inevitably &quot;what differentiates this from node?&quot;<p>Single executable Allows imports from url File system &amp; network Sandboxing is controlled with flags Dies on uncaught errors<p><a href="https:&#x2F;&#x2F;deno.land&#x2F;manual.html#introduction" rel="nofollow">https:&#x2F;&#x2F;deno.land&#x2F;manual.html#introduction</a>

Ryan Dahl, creator of node.js started this project and is also a lead contributor.

Is this a new site, or did the project recently reach a milestone, or is this just resurfacing?<p>I&#x27;m really excited about this project, especially the first-class TypeScript. Could easily see it replacing node for me!

What makes this different from something like <a href="https:&#x2F;&#x2F;github.com&#x2F;Agoric&#x2F;SES" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Agoric&#x2F;SES</a> ?

I admittedly haven&#x27;t researched too deeply, but are there any examples&#x2F;docs on embedding Deno in another Rust program and&#x2F;or writing&#x2F;exposing Rust libs with a TS API?

&gt; A Secure Runtime for JavaScript and TypeScript<p>So, does it support a specific ECMAscript version? Or am I restricted to the Typescript JS definition? This is confusing..

Does &quot;secure&quot; implies some protections against Spectre-like attacks?

Careful with Deno, performance is still low: <a href="https:&#x2F;&#x2F;user-images.githubusercontent.com&#x2F;3397140&#x2F;48649635-89060d00-e9f3-11e8-9447-d4dbd050a310.png" rel="nofollow">https:&#x2F;&#x2F;user-images.githubusercontent.com&#x2F;3397140&#x2F;48649635-8...</a>

Would be nice also to have the V8 implementation in Rust as well.
