ACTIX TUTORIAL PDF – 27 Mar I built my service on actix-web, a web framework layered on actix, an actor library for Rust. actix is similar to. In this tutorial we will be using postgresql so follow the instructions to setup for postgres. You need to have a running postgres server and can. Welcome back to part 2 of the tutorial. In part one we have successfully setup bulk base of our Auth microservice. Congratulations if you have.

ACTIX TUTORIAL PDF
Resources to understand actix-web? I’m going through the documentation on actix web but the only back end web dev I’ve done is in Django where there is an explicit way to design things.
My lack of experience has made it really hard to understand the “examine each puzzle piece individually then assemble them yourself” approach towards documenting actix web. Do you know of any good, ground up tutorials for understanding how to build a web application with actix? It’s not a tutorial, but the examples are quite useful.
So if you think something is hard to understand the community is very helpful and active in gitter. There’s a set of “ground up” pages on the official site: I just went through this process and also come actkx a Python background. My advice in no particular order:. The actix and actix web APIs are under very active development aka unstable. Yes, your going to need to read the raw source code especially the test suites and examples.
Make sure you read the right release tutorizl The documentation and book are incomplete and totally insufficient for more than a toy project. Django and Python are very mature projects. Rust and Actix are very bleeding edge.
It will likely take you roughly 3x longer to implement the same service in actix-web. Here’s some relevant Actix documentation. That doesn’t help you much but if you are curious, trying out those languages I suggest Elixer could help you get into the right mindset.
Constructive comments only.
Actix-web currently contains rather irresponsible use of unsafe blocks that, according to one of the developers, may take a while to resolve and cause an API change. Even if you do actxi run into the issues caused by that, you will have to change your code to accommodate the new API very soon. So don’t learn actix-web just yet. Either come back in a month or so or try another framework, e. This is a silly comment. I work in computer security, my background was closer to systems, then moving to web services, zctix forensics.
It is fair to say that a basic understanding of memory safety is at least one component of my job, and at acfix point was the primary focus when I was first getting into security and did vuln research and exploit dev – intern years.
Don’t speak for others like this, it’s really condescending.
You don’t know who any of us are. You shouldn’t presume to understand things better than us. People come to rust because rust is marketed as memory safe. If code is not memory safe it is not meeting a basic, marketed premise of the language. Using unsafe to the extent that actix did was a mistake. It’s a cool library, glad it’s being worked on, I have a lot of faith in the developer’s skills. That doesn’t change anything. Calling it melodramatic that people, gasp, do not want to use unsafe libraries in a language that touts safety is The joy of memory bugs is that you often times don’t know they are happening, just occasionally small unexplainable problems occur that you ignore.
The best case is when the OS notices and kills the process. There were several more than 10 ways for a user to trigger these UB scenarios, and the compiler wouldn’t have caught them.
It’s hard to know how many deployments have cases where they are triggered. While it’s excellent to be fixing these issues, it’s also important to note that a couple of the easiest to trigger cases still exist in master, and none of it tutoriwl yet released to users. So, users must still exercise great caution. Why even have this conversation? You’re being extremely defensive for no reason. No one is saying the developer is bad. For the billion time, no one is attacking the developer.
I don’t trust developers, I trust code. If code has a lot of unsafe blocks, that means there’s a lot of code that isn’t covered by the safety checks of the compiler. These blocks need to be manually checked, and with a highly concurrent project like a web framework, that’s a difficult and error-prone task.
I don’t have the time to manually check unsafe blocks, but 10 is potentially doable. And I’m sure many others feel the same tutoriall. What worries me actis most is that, allegedly, there’s no justification in the code for many of the unsafe blocks.
I haven’t looked at the code myself, but it’s on my to-do list as I consider it for a few projects I’m working on. I really don’t understand your argument here. Why throw away safety axtix the language gives you? If there’s a good reason to have an unsafe block, then I don’t see actic it should be avoided, but I do expect there to be a comment explaining why unsafe was used and why the code is safe.
I expect the same for any other project that does concurrency when safety is not clear e. There’s also a acti between “working” code and “safe” code. The former may work today but break unexpectedly later e. I’ve had the former break on me, which is a large reason why I’m interested in Rust I made a poor design decision because of a misunderstanding of some documentation. I like libraries I use to be as safe as possible, so why is it unreasonable to request it from a language that makes safety a core part of the design?
Leave the image macros at home. When discussing other acyix languages, maintain civility and respectfulness. Submissions must be on-topic. All submitted posts must explicitly reference Rust or link to repositories written in Rust. Posts do not necessarily need to be technical in nature, e. If you have a link that does not mention Rust but you believe would be of interest to the community, then please either wrap the link in a self-post that explains its relevance or leave a top-level comment to that effect.
A programming language is a pretty silly thing to get upset over. Read the official Rust book it’s free! Skim the release notes. Compile online in the Playground. Install Grab the binary installers.

Want to add to the discussion? My advice in actox particular order: Are we web yet? So I think we are ok. Things will be smooth soon. Actix still is the best rust web framework around.
I don’t get it. Who could possibly care about something this irrelevant? Why even mention it then?
