deploy_feedback VS deno

Hey all, Andy from the Deno team here. We're excited to share with you Deno Subhosting, an easy way to extend your platforms functionality by securely running untrusted JavaScript written by your users.

When we first launched [Deno Deploy](https://deno.com/deploy) in 2021, we were surprised at the volume of requests from companies about getting access to the APIs needed to run Deno Deploy. Many companies wanted to give their users the ability to write custom logic in their app, but setting this up in the cloud presents security concerns and a ton of infra work/maintenance.

We realized that there was an opportunity for Subhosting to solve a larger problem, which is allowing companies to easily and securely run custom code written by their users, without the hassle of maintaining said infrastructure.

Though we do have a few subhosting customers (Netlify being one of them), this launch makes our Subhosting product self-service, so any development team interested in extending their platform via their users' custom code can do so by [signing up](http://dash.deno.com/subhosting/new_auto) and [reading our docs](https://docs.deno.com/deploy/manual/subhosting). We have [an updated pricing model for Subhosting](https://deno.com/deploy/pricing?subhosting) as well, including a generous free tier fit for kicking the tires and building a proof-of-concept.

We'd love to get your feed back. Have you ever talked to your co-workers about allowing external devs to "have at it" with your platform? What would it look like to unlock the final 10% for your top customers? How have you approached this problem in the past?

Thanks for reading and the Deno team will be responding to comments!

That means we don’t need to transpile the Typescript code to ESM or CJS. Currently, only Deno Deploy can run your Typescript function out of the box. However, in order to keep the code small, we still need some sort of bundling. Luckily, Bun is also a bundler 😉

What type of apps do you code for your day-job? (I program for fun and curiosity, so that is why I ask that lame question.)

Do you use node.js? Deno is brought in part by the Node.js creator, Ryan Dahl, who wanted to fix/improve a lot of things he didn't like in node.js.

They also have "Deno Deploy" (with a free tier) to run your code on different servers scattered throughout the globe: https://deno.com/deploy

One of the reasons I love the `deno` executable is you can use `import` statements in your code and then tell `deno` to merge everything into a single .js file. I would then take that and publish it to Cloudflare Workers. I know you can do this with node.js and a bunch of tools, but it is so much simpler with `deno`.

The online version of DocTrack is hosted through Deno Deploy and is accessible here.

It runs on https://deno.com/deploy which runs on gcp at the moment but my understanding is that the underlying cloud provider could change at any time.

For deployment Deno offers it's own service, Deno Deploy:

https://deno.com/deploy

Disclaimer: Haven't used it yet.

Deno functions. Its different than docker containers that auto scale. https://deno.com/deploy

One of the biggest annoyances with Deno deploy/functions is that there is no way to store any data. This would be very useful to e.g. cache an auth token, store a key/value pair, etc. See also: https://github.com/denoland/deploy_feedback/issues/110

Is any work being done to fix this? Or is this out of scope currently?

One of the valuable features of Solid Start is that you can use so-called "adapters" to completely change the output into something deployable basically everywhere that serves pages and with quite a lot of options: there are adapters for amazon web services, cloudflare pages and workers, deno deploy, netlify, standard node server (the default), vercel, and static deployment - the latter allows us to build something that we can put on github pages.

NodeJS is the dominant Javascript server runtime environment for Javascript and Typescript (sort of) projects. But over the years, we have seen several attempts to build alternative runtime environments such as Deno and Bun, today’s subject, among others.

https://github.com/denoland/deno/issues is the ideal place -- we try to triage all incoming issues, the more specific the repro the easier it is to address but we will take a look at everything that comes in.

Install Node.js (or Bun, or Deno, or whatever JS runtime you prefer) if it's not there

QUIC is very exciting, after seeing what it can do for performance in Cloudflare network and Cloudflare workers, I can't wait to finally see it in Deno[0] 1.41.

So as an end user it's kind of like https://deno.com/ where you buy into a runtime + comes prepacked with DBs (k/v stores), scheduling, and deploy stuff?

> by storing Unison code in a database, keyed by the hash of that code, we gain a perfect incremental compilation cache which is shared among all developers of a project. This is an absolutely WILD feature, but it's fantastic and hard to go back once you've experienced it. I am basically never waiting around for my code to compile - once code has been parsed and typechecked once, by anyone, it's not touched again until it's changed.

Interesting. Whats it like upgrading and managing dependencies in that code? I'd assume it gets more complex when it's not just the Union system but 3rd party plugins (stuff interacting with the OS or other libs).

~90MB+ at this stage and do now allow compression without erroring out. Deploying ala Golang is not feasible at that level but could well be down the line if this dev branch is picked up again!

The exe output grew from from ~50MB to plus ~90MB from 2021 to 2024: https://github.com/denoland/deno/discussions/9811 which mean Deno is worse than Node.js's pkg solution by a decent margin.

Behind the scenes is a simple Sveltekit-powered server function to fetch a Spotify client token then find a user's recommendation playlist and its track information. A Deno edge function to performs this data fetch and renders server-side Svelte.

If your application is written in JavaScript, integrating it with JavaScript extensions is a no-brainer. However, Secutils.dev is entirely written in Rust. How would I even begin? Fortunately, I recently came across an excellent blog post series explaining how to implement your JavaScript runtime in a Rust application with Deno:
