autopush-rs VS jelly-actix-web-starter

> Is it say possible to run a production quality server that can handle hundreds of thousands of concurrent users on digital ocean lets say?

Absolutely. I used to work as an SRE on Mozilla's WebPush infrastructure. Every running Firefox in the world establishes a connection to it; that means it peaks at tens of millions of concurrent connections every day. We could easily handle hundreds of thousands of connections on a couple CPU cores and gigs of RAM.

Although most connections were usually idle, we also regularly pushed messages to every connected client (e.g. when a collection in our remote settings service was updated).

It's written in Rust using Actix.

You can look at https://github.com/secretkeysio/jelly-actix-web-starter

My usual reminder that I have a Django-ish template for actix-web that I maintain: https://github.com/secretkeysio/jelly-actix-web-starter

Now that actix-web 4.0 is out I should be able to finally resolve one of the open issues/PRs, which I was waiting on 4.0 for.

For those interested in Django-in-Rust type approaches, I maintain an actix-web starter project that does exactly this: https://github.com/secretkeysio/jelly-actix-web-starter

I maintain a starter for all of this kind of stuff on top of actix-web, for anyone interested: https://github.com/secretkeysio/jelly-actix-web-starter/

Curious why you went with the mailbox approach - since a request is pretty much in-and-out, I found it sufficient to just write a trait for HttpRequest and have a custom render(...) method that pulls any flash messages from the session, thus clearing them. Wouldn't surprise me if I'm missing something tho.

I love Askama, but being tied to compile time changes is an absurd handicap on a web framework in the initial iteration phase. With Tera, you can implement a watcher for template changes and reload them without needing to recompile the entire framework.

If you want, I have an open source actix-web repo that does stuff like this for you already.

If you enjoy Python's web story but want something similar-ish in Rust, you can check out my actix boilerplate repo - it "mimics" Django in many ways. If nothing else, might be useful for picking apart.
