Hi! Author here. I have spent a lot of time thinking about this and believe that the most straight forward solution for long running (or even forever running) workflows is to allow hot upgrades. A hot upgrade would only succeed if you can e

Flawless integrates with your existing system. You probably don't need the guarantees that flawless provides for all code, but just specific functions/workflows.

Thank you! I hand coded it with just HTML, CSS and JavaScript and put a lot of effort and love into it. The code is not the prettiest, but the implementation is straight forward if anyone wants to check it out https://flawless.de

Hi! I'm the author of flawless. By using WebAssembly, it's kinda by default fool proof. WebAssemby explicitly requires you to declare host calls inside your modules. If you try to use another host call that is not provided by flaw

> It is probably important here to realize that async solves concurrency, not parallelism. You can use async with a single threaded runtime for I/O concurrency and mix that with threads for computational parallelism for long running

I also dislike this name, as it was not clear what it does just by looking at the name. Recently, I was adding a similar abstraction to Rust on a project I'm working on and I called it `AbstractProcess`. Like, it is some kinda of templ

Wait! The ? operator works with the `Option<T>` type? I assumed it was only reserved for `Result<T,E>`.

Hot reloading is always a pit tricky. The programming model needs to explicitly support it. In lunatic it will consist of 2 parts: 1. Stuff inside the vm that lets you keep the process id and message queue, but replaces the code running. 2.

Thanks! You can already do this in lunatic. For example, in the Rust library you can create a configuration ( https://docs.rs/lunatic/latest/lunatic/struct.ProcessConfig.... ) with specific permissions (e.g. no

We take the Phoenix approach of splitting the DOM into static and dynamic parts. In fact, we even re-use the pheonix.js library on the frontend, so we just implement the backend part that speaks the same protocol as Phoenix. I don't th

What a coincidence, I was just discussing on discord a similar approach for our Rust web framework submillisecond[0]. Submillisecond uses lunatic to run Rust code compiled to WebAssembly on the backend. We are working on a LiveView-like lib

There are many other properties that WebAssembly gives us that would be hard (impossible?) to achieve with native Rust. Erlang-like fault tolerance based on a concurrency model where each unit gets their own heap. Fine-grained per request s

Web socket support was added a few days ago[0], but it's still not part of a release. I will probably push out alpha1 tomorrow including it and a few other changes. [0]: https://github.com/lunatic-solutions/submill

You can get a WebAssembly instance running in a few micro seconds. This makes it feasible to spawn a new sandbox for each request and scaling down to zero becomes almost trivial. Another benefit is that you are not bound to a specific OS&#x

There are still many problems to be solved. One is the state syncing between backend and frontend. There is nothing public yet, until we decide on the direction that we want to actually take.

Yes. We could use the in-browser wasm engine + a polyfill for the host functions. Of course, this would have some limitations. Functionality like UDP would not be supported.
