fartscroll.js VS marshal.ts

We have types at home.

My litmus test regarding whether I can even consider using a library in production is: does it have more stars than fartscroll.js?

https://github.com/theonion/fartscroll.js/tree/master

Most of the entries there are below that number, which begs the question: is this really that much of a problem that it mandates the drastic changes required?

I actually don't know if it's even doable, considering TS's structural type system, where the answer to the question "what type is X?" is not straightforward.

The best content produced by The Onion was a JavaScript library to make farting noises on scroll events: https://github.com/theonion/fartscroll.js

As a sort of litmus test I use the number of stars a superset of(or language compiling to) JavaScript has on GitHub and how that compares to fartscroll.js: https://github.com/theonion/fartscroll.js/

By this measure ReScript is still a niche language.

zod or yup gets you quite a bit of the way there in practice - when you would reach for a Typescript type, making it in zod instead is more verbose but gives that runtime layer.

But for those who actually want full-stack non-stripped runtime type reflection based on Typescript syntax alone... https://deepkit.io/ - https://deepkit.io/blog/introducing-deepkit-framework - is a really promising and cool project.

It patches the typescript compiler (which pointedly considers runtime type information out of scope) with its own type compiler that emits a bespoke bytecode that is executed in a bespoke VM to communicate runtime type information to both server and client as needed. https://docs.deepkit.io/english/runtime-types.html

And from that baseline, there are very cool things you can do like an ORM entirely based on type annotations https://docs.deepkit.io/english/database.html or strongly-typed RPCs https://docs.deepkit.io/english/rpc.html .

It's very much in the alpha stage, but it's really well thought out - there's a tremendous degree of care the developer is taking towards code cleanliness and developer experience. I'm torn between wishing this project to have a fully funded team and take the world by storm, vs. "letting them cook" so to speak and seeing the developer experience unfold organically. Either way, it's a breath of fresh air into the Typescript ecosystem!

Deepkit (listed in the article) is a fascinating project and really deserves to be more popular.

It also demonstrates that what is being asked for is actually practical.

Checkout deepkit One of the things it has is a really fast BSON parser, that is faster than the JSON one to my understanding. Interesting work with TS types too

Hello HN community! I’m one of the founders of Magma, a multiplayer art platform. You might recall our earlier post (https://news.ycombinator.com/item?id=30869131), and today we’re sharing a significant update with our artist-focused, multiplayer AI assistant, a first in the realm of collaborative creative tools. Hope you’ll like it!

See how it works in this YouTube video: https://www.youtube.com/watch?v=ZESJfjwxLjk. For in-depth understanding, here’s our documentation (https://help.magma.com/en/articles/6711598-beta-ai-assistant) and our AI manifesto (https://magma.com/aimanifesto) which is a guiding document for us.

We're inviting you to get hands-on with this new feature. Join any of these canvases (up to 50 live contributors each): https://magm.ai/qnss, https://magm.ai/ei74, https://magm.ai/38mr, https://magm.ai/z1ti, https://magm.ai/zdub, https://magm.ai/ed93, https://magm.ai/1l84, https://magm.ai/xvu5, https://magm.ai/gd9j, https://magm.ai/pu6e. All of these canvases have extra feature flags enabled but if you’d like to go beyond them, feel free to join our beta community https://magm.ai/magma-beta-artspace-invite

Our artist-first approach is rooted in our belief that human creativity should remain the heart of artistry. With our AI handling routine tasks, artists can focus on true creativity. Importantly, our AI preserves artists' copyright as it provides a clear distinction between human-generated and AI-generated content.

Beyond just art, Magma is a powerful tool for game dev and animation, offering powerful design & review tools for all stages of the creative process. Our Slack/GDrive-like workspaces (we call them Artspaces) expose API and even shell tools. One can even render any artwork in the terminal. :)

Technically speaking, our collaborative drawing engine is powered by Typescript, Node.JS, WebGL, with a hint of WebAssembly for hand-optimized performance that even Chromebooks can handle. The backend also leverages a high performance Typescript Deepkit Framework https://deepkit.io

Our AI assistant runs on a worker-based architecture akin to Gitlab CI workers, currently leveraging Stable Diffusion 2.1. Future developments will allow connecting your own AI worker, training custom models within Magma, and plugging in API keys from other AI backends.

Feedback, questions, thoughts? Let's discuss! Happy creating with a helping hand of AI!

P.S. A shout-out to the HN community, our last post here helped us connect with an amazing technical angel investor who has made significant contributions. Looking forward to more such productive connections!

Take a look at restfuncs then. Or deepkit or telefunc.

Both work out of the box very well with Deepkit. You can either construct your own types in runtime or mix TS types with runtime information. See for example https://github.com/deepkit/deepkit-framework/blob/master/packages/framework/src/crud.ts where this is done

Yes, you can directly use the interfaces and types as is with Deepkit (https://deepkit.io) and the library deepkit-openapi. You get also full route documentation if you use the deepkit/http router where you can use interfaces and type aliases plus validation thpes for route parameters (query parameters, body, etc). It still in alpha, but approaches soon beta.

https://deepkit.io/ may be of interest to you! It deeply patches the TS type compiler to make all types visible at runtime, enabling a lot of annotation-style workflows and dependency injection possible completely within the type annotation system: https://docs.deepkit.io/english/runtime-types.html

Previous discussion: https://news.ycombinator.com/item?id=31663298 - it's downright mindblowing that all this seems to be the work of primarily a single developer.

For a less intrusive solution, https://github.com/jquense/yup is a great library to reach for whenever you're defining the shape of a network-transmitted object and don't want to introduce compilation stages.
