Hi There, It was a very comprehensive tutorial on axum, but I am stuck at one point, the function where we create mw_require_auth at timestamp: 41:43. I am getting an error *struct takes 0 generic arguments but 1 generic argument was supplied expected 0 generic arguments*. axum::middleware::Next does not any generic arguments, and when I following the video, this was giving me trouble.

[@JeremyChone]

Which Axum version you use ?

[@JeremyChone]

It seems you are using Axum 0.7, I am must finishing a video to show how to update. In the meantime, remove on text, and put Request from axum::body::Body, and you can remove the generic on the mw function. Should work.

Hi Jeremy, great tutorial. I have one suggestion: it would be helpful if, at the start of each step, you stated more explicitly what you want to achieve by the end of the step. You do this to some extent, but sometimes things only make sense in hindsight. Again, great tutorial!

Incredible tutorial. I am coming from the embedded world of C with a tiny bit of Rust experience, so the Rust things are a bit more familiar to me than the web development things. As I am going through this tutorial (and the follow-along), I am starting to really understand the intricacies of the backend. It is so clear that you have put tons of effort into preparation -- when I rewind and watch over, it's not because your explanations are confusing, but because you have managed to distill a lot of knowledge into a little bit of time! Instant subscribe here, this is amazing stuff.

Great, thank you for the detailed feedback. I'd appreciate your feedback on the web-app production coding session as well-it's 3 hours and 50 minutes long, so take your time. I'm also working on the second episode of the web-app production coding series, which should be informative too.

Thank you so much for this great tutorial. The teaching pace is quite fast and it was no piece of cake to understand all the methods you use as a rust noob (I've only read "the book", so sometimes, I was wondering "why does he uses as_ref() instead of the borrow checker, etc.)), but it was very interesting and informative. Big up to you!

One problem you might face if you decide to implement login in a different route (e.g. "/auth/login" instead of "/api/login"): Make sure to set the auth cookie's path to "/".

@@sampathsris yes, very important to set the path to /. Something I forgot to mention in this video.

[@ChasingShadowsz]

Fantastic video Jeremy. I learned so much in this video, thank you 🙏🙏🙏. One small tip: you can use ULIDs instead of UUIDs to get timestamped and sortable IDs, which are certainly useful when using IDs inside logs!

[@JeremyChone]

Thanks for the kind words! Also, thank you for the note about ULIDs; they can indeed be used. In our case, we prefer timestamps (UTC ISO8601) and UUIDs because their conversions back and forth to numbers are well-known and widely supported. For log analytics, having these two as unsigned numbers can make a significant difference when querying large data sets (e.g., with dataframe tools).

[@flyingsquirrel3271]

12:58 This seems to be currently broken in the latest axum version. At least for me this fails at runtime due to a false assertion in axum code (version 0.6.15), so I'm pretty sure, it's a bug. I tried axum 0.6.0 and it just worked, even without wrapping "SaveDir.." into "get_service". Edit: 0.6.12 seems to be the latest version where it works. In all versions newer than that, it fails.

[@JeremyChone]

Yes, see comment in the description. There was a bug introduced in `0.6.15`. In the cargo.toml put a `=0.6.12` for now. Here is the Axum ticket I filed: github.com/tokio-rs/axum/issues/1931, should be released soon.

[@flyingsquirrel3271]

@@JeremyChone Haha okay thanks, I guess I should have read the description before searching the error myself. Maybe you could add some kind of annotation to the video at that timestamp (If that's easily possible with youtube)? That would probably save a lot of people some time ;-)

This would be a Link Card, but unfortunately, I can't add them. To do so, you need to be part of the KZbin Partner Program. However, for some strange reason, Google AdSense revoked my AdSense account, which removed me from the YPP. It's a bummer, as I didn't realize I would lose this feature.

[@PeterFaria]

Regarding the delete implementation in 'CRUD - REST API', I’ve often found it easier to consume from the client if the server returns '204 NoContent', even if the item isn’t found. This makes the call idempotent, which allows the client the ability to retry in case of the prior call failing for any number of reasons. 32:39

Really amazing tutorial : D. Was wondering if you could elaborate on the model controller architecture you used and what it's called? Is it a derivation of MVC?

[@JeremyChone]

Thank you. Your timing is great, as I am currently constructing the follow-up course, which focuses on best practices for production code. We'll be dividing the ModelManager (which maintains the model-related application states, such as db_pool) and the ModelController, drawing inspiration from the Data Access Object (DAO) pattern. In a project management data model, for instance, you might have: A ProjectBmc (Backend Model Controller) that handles Create, Read, Update, and Delete (CRUD) operations, and possibly more, for Project entities. Similarly, a TaskBmc would manage the CRUD operations, and potentially additional ones, for Task entities. This approach gives you complete control over the data structures and access methods in your Application Domain, while still allowing for code reuse and normalization. Next course is schedule for June 4th.

[@emanueley8410]

I've been following along this awesome course and the first time I stumbled was at 54:35 where you say "and now we just do a 'ctx-question mark'." It seemed weird because ctx isn't passed anywhere, no method is called on it and as I am new to Rust it took me moment to understand what that means. A Rust-beginner-friendly comment would be that this has the effect of evaluating whether ctx (which is a Result) contains an error and raising ie, propagating it.

This is a very well done tutorial. Actually useful and well beyond the standard "hello world" nonsense you usually see. This guy does very good videos.

[@pb3030]

I have a question / thought. By making the context extractor clone the context result you force the crate's Error type to implement Clone. This cascades into an issue with a real world app using 3rd party db's like sqlx. Because we would probably want to use thiserror and #[from] to convert sqlx errors into your crate's custom error type. If you use several external libraries and want to convert several external errors this can be a headache. I handled by implementing From and using a String as the error date.

Hello Jeremy. Thank you for your videos about axum, I enjoyed watching them. When I started testing the code myself, I became curious about what was in req.extencions, but I couldn’t do it. Do you have any ideas on how this can be done? here is an example of what I would like to receive pub async fn mw_ctx_resolver( cookies: Cookies, mut req: Request, next: Next, ) -> Result { .... println!("{req.extensions.len():?}") // 6 // output 6 records for (key, value) in req.extensions.iter() { println!("Key: {:?}, Value: {:?}", key, value); } }

[@JeremyChone]

Ah, `Extensions` is a wrapper around "AnyMap," which is a HashMap of `TypeId`. Axum uses the `http` implementation of `Extensions` (I believe there are a couple implementation of "TypeMap"). You can find find the http/axum one here: github.com/hyperium/http/blob/master/src/extensions.rs I do not think it implements `Iter` or `IntoIter`, which is why you cannot use a for loop on it.

This is such an awesome "quickstart" guide for newbies into rust like me. Question: how do you handle token claims validation (possibly in the middleware) assuming the token is not stored in a db?

Hi, thanks for the great video. One question tho, how come the Ctx extractor gets called twice between mw_ctx_resolver and mw_require_auth after we implement the server log line? I know one of the calls is to extract the Ctx for mw_require_auth, but what about the other one?

[@JeremyChone]

The mw_ctx_resolver resolves the CTX (essentially performing the authentication) and then stores it in req.extensions, so it doesn't need to be computed again. The mw_ctx_require is an optional middleware that ensures anything following it has a CTX, even if they don't explicitly require it. This is currently just an optional safeguard because downstream handlers that request CTX will fail if there isn't one. However, it's good to have.

Wonderful tutorial! Something im noticing is that the returning status code is not the same as error IntoResponse status code. For a failed login it should return 403 but it's returning 500, did I miss something?

[@JeremyChone]

Thanks for the kind words. It does send back a 403 Forbidden if the wrong login. (with the full final code). Here is how it works: - The impl IntoResponse for Error creates a placeholder for the real error. - The main_response_mapper will get the error and call the client_status_and_error, which will return the appropriate status code and send that back to the client. If you go to the quick_dev, and change the password on the login, you will see the login and tickets response with the following status: Status : 403 Forbidden Hope this helps. I just tested the code, and works as expected. Let me know if you have any further question.

All the html element is rendered correctly but not an image file. it sits in the img element under a element in the DOM hierarchy. One more thing why is that Axum doesn't print an error message by default if something fail. It is not Django, but perhaps we need to enable it?

Thank you for this great tutorial. In this vedio, I wonder your vscode plugin setting, especially multi region annotation part..

[@JeremyChone]

I put some of my VSCode settings at: rust10x.com/vscode There is the comment-section there, and the key binding for it.

BTW, I finally took some time to create the Rust10x VSCode Extension and a webpage with information about my VSCode setup. Everything can be found here: rust10x.com/vscode

@Jeremy Chone Why do you not provide a means to set headers in your testing client?

[@JeremyChone]

That's a good question. Originally, I didn't aim to delve too deeply into rebuilding Reqwest on top of Reqwest. Instead, I focused more on "browser" use cases, where authentication is typically done with cookies. However, now I agree that it would be beneficial to broaden the scope and allow the setting of headers. The route I'm keen to avoid is the full reconstruction of a Reqwest API using the Reqwest library. My proposed approach is to expose an API like http_client.exec(reqwest_builder), perhaps coupled with some utilities for building these builders. This approach allows developers to use the simple httpc-test API/Prints, while simultaneously harnessing the full power of the Reqwest request builder. Does that make sense?
