Earlier quoted context omitted.

I'd spawn a new DB for that instance too. It can still go a long way to give you a look at how your application worked in the past.

Am I mistaken in thinking that’s totally ridiculous? Let’s charitably say you can run your app with a 1GB cut down snapshot of production. You’re going to do what, save a snapshot of the database for every commit? Every schema migration? …and then provision that up in a running database server… which is notoriously not container friendly… ? It doesn’t sound very plausible to me. Our database is ~1TB, and the app runs…

Plenty of apps can run from an empty database, if the data storage is focused on resources you, the user, have created for yourself.

But I imagine that people with their heads in the future are imagining you'll use one of these new database startups (the names escape me) to manage snapshots, seeding from anonymised production data, etc.

This question is going to make me sound like a jerk, but why do you want to write your back-end in JS? Deno looks like a great improvement over node.js, but I don't feel compelled to use it. It seems like people jumped to node based on some performance promises that didn't really pay off (IMO). And since then, we have newer options like Rust, Go, and Elixir as performant back-end options, and even older choices like…

You're kinda stuck writing JS on the frontend. The (only) advantage of also using it on the backend is that you can share code. In some cases, I could see that being compelling. FWIW, I think Typescript would make an even stronger case. And I think(?) that's one thing Deno is trying to do.

Sharing code is great, I've moved processing between backend and front-end or even share the same code in both. Makes SSR+SPA possible using the same code. Typescript is a must for me, but I don't need Deno for that. I haven't used beyond scripting but for the time being I don't see a mayor benefit over node or ts-node other than easier/zero project setup.

Interesting raise. I leave the front marketing page of Deno Deploy open in my browser for a few moments and I get the ubiquitous "This webpage is using significant energy. Closing it may improve the responsiveness of your Mac." Says it all about the state of the JavaScript ecosystem really.

unfortunately, webdev does not have a strong performance culture. V8 & Blink/Skia can be crazy fast in the right hands, but it does take some effort and profiling to eek it out.

heh, I knew for sure Deno would be successful from the first moment it appeared on HN and people here were critical of it. My rule of: The more HN criticizes it, the more likely it succeeded, still rings true.

So crypto is going to be a giant success?

Hi man, you seem to have found something. Transfer your bank deposits to btc eth, and in a few years you will find that they are far away from the banking institutions.

> Early in cloud computing, virtual machines were the compute abstraction […] This is funny to me because serverless sounds to me like the return of PHP (etc) shared hosting. What's old is new again?

It's worse this time, in that the old shared hosting environments (e.g. Apache with FastCGI and suexec, or nginx with fpm) were open source, and there were countless shared hosts. The new generation of multi-tenant isolate-based JS runtimes are proprietary, and AFAIK one can count the number of hosts on one hand.

You can self-host Cloudflare Workers. https://github.com/cloudflare/miniflare

I can't believe how much of a nuisance JavaScript monoglots make themselves. My God, go learn a server-side language, please. I will teach you if you stop this.

The color changing on this page gives me a migraine: https://deno.com/deploy I like Deno in principle, but I'd love to see how Slack, Github and Netlify are using it.

To a Denoid, that changing color shit is lit!

I find Deno very interesting. It's written in Rust by Mozilla, executing TypeScript by Microsoft on V8 engine by Google, and its name is sorted version of Node.

That aside, I have been very productive with Deno. Web Standards are going in the right direction, and Deno helps using them easy. The Request/Response model with streams make a lot of sense, and provides lots of way to optimize.

I understand performance is not the best compared to Elixir or Rust, but the ability to quickly download Deno, run a web server, import modules through URL, and start hacking and testing, then bundle into a cross-platform executable is a life-saver. No installation step, no build tool in between.

From the post: > For example, it is integrated with GitHub in such a way that on every push it will provision a new server running specifically that code, deployed to the edge, worldwide, and persisted permanently. Want to access the code your app was running a month ago at commit f7c5e19? It will be served up instantly at a moment's notice. It costs you nothing to have that bit of JavaScript responding to requests i…

I hope that app isn't actually running on a server somewhere for each commit indefinitely, and that it's moreso intended for serverless setups, like the Netlift edge functions they mentioned...

We could do with some more consciousness for energy & compute resources in this industry, as decoupled it may be from the real world, clicking the button to deploy an EC2 instance somewhere does use real power and will contribute to hardware wear.
