Thanks a lot for this! actix-web is an amazing framework so far. I've started with the book zero2prod in rust, and using some type driven designed, rust's errors handling, actix-web's extractors and web::data feels like super good ergonomics. I do feel like the docs could be expanded a bit more, I got stuck when trying to write a middleware for example. Congrats for the release!
capableweb 5y ago
That's great to finally hear! I started learning Rust recently and usually start learning new languages by building different kinds of Hacker News clients with the language. This time I focused on a offline-first desktop HN client, that fetches items periodically and allows the user to browse it in a desktop app built with Tauri. While developing this, I started writing a API with Actix Web at the same time, so the same service could be used directly in the browser, not just with the desktop app. So I found Actix Web to be the most supported. However, I jumped into the RC versions (in order to use tokio >v1 which I was already using for other things, and you can't mix versions), while most human-written documentation (website, Stack Overflow, forums and such) were written for the pre-4 version. So I'm glad to see it finally released, and can't wait for all the documentation to/web resources to be properly updated as well so I can learn more about Actix Web. Great work on creating a nice library folks! :)

  "Actix was found by third parties abusing unsafe and when they were auditing most libraries found for Rust on the internet. When the unsafe code was audited it was found that on misuse, it can lead to serious vulnerabilities. So they opened a bunch of issues and added a lot of patches and PR’s in GitHub." Good luck though

    Hey bud, you are being really aggressive and disagreeable in here. At this point, I think everyone is aware that you, personally, would not recommend Rust or Actix. Loud and clear my dude.

    This is an easy mistake to make, but actix-web isn't actix, it's a web framework that uses actix. And while actix once had a controversial reputation regarding unsafety, the project has reversed its stance in the years since that quote was relevant and now appears to treat soundness violations with seriousness.
- cellover 5y ago
  Is this project public? I'd love to have a look at it. Thank you!
  - capableweb 5y ago
    Ish, it's still pre-alpha :) Running it over at https://ditzes.com https://ditzes.com, source code at https://codeberg.org/ditzes/ditzes https://codeberg.org/ditzes/ditzes Waiting for reaching alpha status before I post as a Show HN, want to have the desktop builds publishable before then at least too.

For those who have been considering Rust for your next web dev project, it is a great time to give it a try. Actix Web is a mature offering with ecosystem, community and learning materials, including a few major book publications in the pipeline.
- outside1234 5y ago
  Also check out Axum, which honestly in my hands has the best ergonomics, and is built on top of the Tokio ecosystem. https://github.com/tokio-rs/axum https://github.com/tokio-rs/axum
- msoad 5y ago
  I always wondered if the safety and correctness that Rust offers is needed in a CRUD application? Do you think it pays off to work in the extremely strict system where you can't just cast to any and move on with your product features?
  - woile 5y ago
    I think there are quite some macros that accelerate a CRUD creation app, for example, take a look at sqlx with ormx: https://github.com/NyxCode/ormx https://github.com/NyxCode/ormx
  - tasn 5y ago
    This is something I thought about a lot before switching to Rust at Svix[0]. What I came to realize though, that there are no "casts to any and move on", but rather there are silencing real bugs and praying you won't hit them. Almost every time I've ever tried to silence the type checker (in any other language) it resulted in a bug. Does it make you slower? Definitely at times, but it's mostly OK, and the code is pretty damn clean. You can check out our repo to see how it looks[1]. Edit: we don't use Actix, we use Axum, but the same holds for Actix too.

Anyone got experience using actix web vs rocket? My rough impression is that actix is focused more on performance, rocket on stability and developer ergonomics?
- vladvasiliu 5y ago
  To me, rocket seems much more "batteries included" than actix, which requires you to look around or build your own things if you want to build a bigger app. I'm thinking about authentication, templates, etc. I'm not really a web dev, though, so I may be wrong, or missing something.

- dralley 5y ago
  Plenty of companies (including Microsoft IIRC) are using Actix in production. At this point it's not that shiny and new. Actix is the most mature of the Rust web frameworks. Axum is new but very promising. Rocket is popular but development is stalled at the moment since the main developer has been going through some rough times.

- capableweb 5y ago
  What libraries like this could you really extract "performance/$" from? Sounds like a mostly financial metric. It's so situational that you cannot say outright exactly how much something cost in different scenarios. Doing so requires strict metrics about other things at the same time, and could only be done as an analysis of what happened, not what will happen in the future. Subtle bugs and things like just using a different data structure would impact the performance, down to the tiniest detail. If you're so adamant to see metrics, you could use TechEmpower's framework tests, latest one placing 5th Actix in the "Composite score" (https://www.techempower.com/benchmarks/#section=data-r20&hw=ph&test=composite https://www.techempower.com/benchmarks/#section=data-r20&hw=...), as a result of being pretty high up in the specific benchmarks. But even with that information, it doesn't mean it'll be the 5th fastest framework when you use it. I guess the point is: do you own benchmarks for the specific areas where you need it to be fast, calculate what your costs would be for hosting it, and you'll have your "performance/$".

  Clearly nobody ever manages to use this Go thing with over 700: https://github.com/golang/go/issues https://github.com/golang/go/issues. Or .net, over 5000 issues for the compiler alone: https://github.com/dotnet/roslyn https://github.com/dotnet/roslyn. I'd guess stuff like Java, glibc would be similar if they used github
UltraViolence 5y ago
Why would I choose Actix over ASP.NET MVC with which I'm already familiar and works fast and reliably and doesn't require me to learn another language? There's no need for a deterministic memory managed language in web applications. GC languages such as Java and C# work just fine there.
- Macha 5y ago
  What of people that don't use C#? What of teams with libraries already built in Rust? Also I've been on teams building web apps in Java that were more complicated than just CRUD. We had one where the GC behaviour of Java was decidedly suboptimal as the applications would for for minute long GCs due to large in memory caches
  - UltraViolence 5y ago
    There are very few developers that aren't fluent in C# or Java or another C derived language. The learning curve for Rust is pretty steep, since the deterministic memory management requires new concepts to be mastered whereas with C#/Java you can just create objects left and right without having to worry about when to clean them up. C# and Java have vastly more libraries available to them than Rust. Having sub-optimal behavior is usually a sign of poor design IMHO. But it's difficult for me to pass judgement without seeing the application code. Also, I doubt that Rust would be of any help in this case.

That's great to finally hear! I started learning Rust recently and usually start learning new languages by building different kinds of Hacker News clients with the language. This time I focused on a offline-first desktop HN client, that fetches items periodically and allows the user to browse it in a desktop app built with Tauri. While developing this, I started writing a API with Actix Web at the same time, so the same service could be used directly in the browser, not just with the desktop app. So I found Actix Web to be the most supported. However, I jumped into the RC versions (in order to use tokio >v1 which I was already using for other things, and you can't mix versions), while most human-written documentation (website, Stack Overflow, forums and such) were written for the pre-4 version. So I'm glad to see it finally released, and can't wait for all the documentation to/web resources to be properly updated as well so I can learn more about Actix Web.

Clearly nobody ever manages to use this Go thing with over 700: https://github.com/golang/go/issues https://github.com/golang/go/issues. Or .net, over 5000 issues for the compiler alone: https://github.com/dotnet/roslyn https://github.com/dotnet/roslyn. I'd guess stuff like Java, glibc would be similar if they used github

Why would I choose Actix over ASP.NET MVC with which I'm already familiar and works fast and reliably and doesn't require me to learn another language? There's no need for a deterministic memory managed language in web applications. GC languages such as Java and C# work just fine there.

What of people that don't use C#? What of teams with libraries already built in Rust? Also I've been on teams building web apps in Java that were more complicated than just CRUD. We had one where the GC behaviour of Java was decidedly suboptimal as the applications would for for minute long GCs due to large in memory caches

  There are very few developers that aren't fluent in C# or Java or another C derived language. The learning curve for Rust is pretty steep, since the deterministic memory management requires new concepts to be mastered whereas with C#/Java you can just create objects left and right without having to worry about when to clean them up. C# and Java have vastly more libraries available to them than Rust. Having sub-optimal behavior is usually a sign of poor design IMHO. But it's difficult for me to pass judgement without seeing the application code. Also, I doubt that Rust would be of any help in this case.
