Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

fixed: Don't expose internal type names in QueryRejection response. (#1171)
breaking: Remove extractor_middleware which was previously deprecated. Use axum::middleware::from_extractor instead (#1077)
breaking: Allow Error: Into<Infallible> for Route::{layer, route_layer} (#924)
breaking: MethodRouter now panics on overlapping routes (#1102)
breaking: Remove trailing slash redirects. Previously if you added a route for /foo, axum would redirect calls to /foo/ to /foo (or vice versa for /foo/). That is no longer supported and such requests will now be sent to the fallback. Consider using axum_extra::routing::RouterExt::route_with_tsr if you want the old behavior (#1119)
fixed: If WebSocketUpgrade cannot upgrade the connection it will return a WebSocketUpgradeRejection::ConnectionNotUpgradable rejection (#1135)
changed: WebSocketUpgradeRejection has a new variant ConnectionNotUpgradable variant (#1135)
added Implement TryFrom<http:: Method> for MethodFilter and use new NoMatchingMethodFilter error in case of failure (#1130)
added: Support running extractors from middleware::from_fn functions (#1088)
added: Added debug_handler which is an attribute macro that improves type errors when applied to handler function. It is re-exported from axum-macros
added: Support any middleware response that implements IntoResponse (#1152)
breaking: Require middleware added with Handler::layer to have Infallible as the error type (#1152)
changed: For methods that accept some S: Service, the bounds have been relaxed so the response type must implement IntoResponse rather than being a literal Response
change: axum's MSRV is now 1.60 (#1239)

0.5.10 (28. June, 2022)

fixed: Make Router cheaper to clone (#1123)
fixed: Fix possible panic when doing trailing slash redirect (#1124)

0.5.9 (20. June, 2022)

fixed: Fix compile error when the headers is enabled and the form feature is disabled (#1107)

0.5.8 (18. June, 2022)

added: Support resolving host name via Forwarded header in Host extractor (#1078)
added: Implement IntoResponse for Form (#1095)
change: axum's MSRV is now 1.56 (#1098)

0.5.7 (08. June, 2022)

added: Implement Default for Extension (#1043)
fixed: Support deserializing Vec<(String, String)> in extract::Path<_> to get vector of key/value pairs (#1059)
added: Add extract::ws::close_code which contains constants for close codes (#1067)
fixed: Use impl IntoResponse less in docs (#1049)

0.5.6 (15. May, 2022)

added: Add WebSocket::protocol to return the selected WebSocket subprotocol, if there is one. (#1022)
fixed: Improve error message for PathRejection::WrongNumberOfParameters to hint at using Path<(String, String)> or Path<SomeStruct> (#1023)
fixed: PathRejection::WrongNumberOfParameters now uses 500 Internal Server Error since it's a programmer error and not a client error (#1023)
fixed: Fix InvalidFormContentType mentioning the wrong content type

0.5.5 (10. May, 2022)

fixed: Correctly handle GET, HEAD, and OPTIONS requests in ContentLengthLimit. Request with these methods are now accepted if they do not have a Content-Length header, and the request body will not be checked. If they do have a Content-Length header they'll be rejected. This allows ContentLengthLimit to be used as middleware around several routes, including GET routes (#989)
added: Add MethodRouter::{into_make_service, into_make_service_with_connect_info} (#1010)

0.5.4 (26. April, 2022)

added: Add response::ErrorResponse and response::Result for IntoResponse-based error handling (#921)
added: Add middleware::from_extractor and deprecate extract::extractor_middleware (#957)
changed: Update to tower-http 0.3 (#965)

0.5.3 (19. April, 2022)

added: Add AppendHeaders for appending headers to a response rather than overriding them (#927)
added: Add axum::extract::multipart::Field::chunk method for streaming a single chunk from the field (#901)
fixed: Fix trailing slash redirection with query parameters (#936)

0.5.2 (19. April, 2022)

Yanked, as it contained an accidental breaking change.

0.5.1 (03. April, 2022)

added: Add RequestParts::extract which allows applying an extractor as a method call (#897)

0.5.0 (31. March, 2022)

added: Document sharing state between handler and middleware (#783)
added: Extension<_> can now be used in tuples for building responses, and will set an extension on the response (#797)
added: extract::Host for extracting the hostname of a request (#827)
added: Add IntoResponseParts trait which allows defining custom response types for adding headers or extensions to responses (#797)
added: TypedHeader implements the new IntoResponseParts trait so they can be returned from handlers as parts of a response (#797)
changed: Router::merge now accepts Into<Router> (#819)
breaking: sse::Event now accepts types implementing AsRef<str> instead of Into<String> as field values.
breaking: sse::Event now panics if a setter method is called twice instead of silently overwriting old values.
breaking: Require Output = () on WebSocketStream::on_upgrade (#644)
breaking: Make TypedHeaderRejectionReason #[non_exhaustive] (#665)
breaking: Using HeaderMap as an extractor will no longer remove the headers and thus they'll still be accessible to other extractors, such as axum::extract::Json. Instead HeaderMap will clone the headers. You should prefer to use TypedHeader to extract only the headers you need (#698)

This includes these breaking changes:
- RequestParts::take_headers has been removed.
- RequestParts::headers returns &HeaderMap.
- RequestParts::headers_mut returns &mut HeaderMap.
- HeadersAlreadyExtracted has been removed.
- The HeadersAlreadyExtracted variant has been removed from these rejections:
  - RequestAlreadyExtracted
  - RequestPartsAlreadyExtracted
  - JsonRejection
  - FormRejection
  - ContentLengthLimitRejection
  - WebSocketUpgradeRejection
- <HeaderMap as FromRequest<_>>::Rejection has been changed to std::convert::Infallible.
breaking: axum::http::Extensions is no longer an extractor (ie it doesn't implement FromRequest). The axum::extract::Extension extractor is not impacted by this and works the same. This change makes it harder to accidentally remove all extensions which would result in confusing errors elsewhere (#699) This includes these breaking changes:
- RequestParts::take_extensions has been removed.
- RequestParts::extensions returns &Extensions.
- RequestParts::extensions_mut returns &mut Extensions.
- RequestAlreadyExtracted has been removed.
- <Request as FromRequest>::Rejection is now BodyAlreadyExtracted.
- <http::request::Parts as FromRequest>::Rejection is now Infallible.
- ExtensionsAlreadyExtracted has been removed.
- The ExtensionsAlreadyExtracted removed variant has been removed from these rejections:
  - ExtensionRejection
  - PathRejection
  - MatchedPathRejection
  - WebSocketUpgradeRejection
breaking: Redirect::found has been removed (#800)
breaking: AddExtensionLayer has been removed. Use Extension instead. It now implements tower::Layer (#807)
breaking: AddExtension has been moved from the root module to middleware
breaking: .nest("/foo/", Router::new().route("/bar", _)) now does the right thing and results in a route at /foo/bar instead of /foo//bar (#824)
breaking: Routes are now required to start with /. Previously routes such as :foo would be accepted but most likely result in bugs (#823)
breaking: Headers has been removed. Arrays of tuples directly implement IntoResponseParts so ([("x-foo", "foo")], response) now works (#797)
breaking: InvalidJsonBody has been replaced with JsonDataError to clearly signal that the request body was syntactically valid JSON but couldn't be deserialized into the target type
breaking: Handler is no longer an #[async_trait] but instead has an associated Future type. That allows users to build their own Handler types without paying the cost of #[async_trait] (#879)
changed: New JsonSyntaxError variant added to JsonRejection. This is returned when the request body contains syntactically invalid JSON
fixed: Correctly set the Content-Length header for response to HEAD requests (#734)
fixed: Fix wrong content-length for HEAD requests to endpoints that returns chunked responses (#755)
fixed: Fixed several routing bugs related to nested "opaque" tower services (i.e. non-Router services) (#841 and #842)
changed: Update to tokio-tungstenite 0.17 (#791)
breaking: Redirect::{to, temporary, permanent} now accept &str instead of Uri (#889)
breaking: Remove second type parameter from Router::into_make_service_with_connect_info and Handler::into_make_service_with_connect_info to support MakeServices that accept multiple targets (#892)

0.4.8 (2. March, 2022)

Use correct path for AddExtensionLayer and AddExtension::layer deprecation notes (#812)

0.4.7 (1. March, 2022)

added: Implement tower::Layer for Extension (#801)
changed: Deprecate AddExtensionLayer. Use Extension instead (#805)

0.4.6 (22. February, 2022)

added: middleware::from_fn for creating middleware from async functions. This previously lived in axum-extra but has been moved to axum (#719)
fixed: Set Allow header when responding with 405 Method Not Allowed (#733)

0.4.5 (31. January, 2022)

Reference axum-macros instead of axum-debug. The latter has been superseded by axum-macros and is deprecated (#738)

0.4.4 (13. January, 2022)

fixed: Fix using incorrect path prefix when nesting Routers at / (#691)
fixed: Make nest("", service) work and mean the same as nest("/", service) (#691)
fixed: Replace response code 301 with 308 for trailing slash redirects. Also deprecates Redirect::found (302) in favor of Redirect::temporary (307) or Redirect::to (303). This is to prevent clients from changing non-GET requests to GET requests (#682)

0.4.3 (21. December, 2021)

added: axum::AddExtension::layer (#607)
added: Re-export the headers crate when the headers feature is active (#630)
fixed: sse::Event will no longer drop the leading space of data, event ID and name values that have it (#600)
fixed: sse::Event is more strict about what field values it supports, disallowing any SSE events that break the specification (such as field values containing carriage returns) (#599)
fixed: Improve documentation of sse::Event (#601)
fixed: Make Path fail with ExtensionsAlreadyExtracted if another extractor (such as Request) has previously taken the request extensions. Thus PathRejection now contains a variant with ExtensionsAlreadyExtracted. This is not a breaking change since PathRejection is marked as #[non_exhaustive] (#619)
fixed: Fix misleading error message for PathRejection if extensions had previously been extracted (#619)
fixed: Use AtomicU32 internally, rather than AtomicU64, to improve portability (#616)

0.4.2 (06. December, 2021)

fix: Depend on the correct version of axum-core (#592)

0.4.1 (06. December, 2021)

added: axum::response::Response now exists as a shorthand for writing Response<BoxBody> (#590)

0.4.0 (02. December, 2021)

breaking: New MethodRouter that works similarly to Router:
- Route to handlers and services with the same type
- Add middleware to some routes more easily with MethodRouter::layer and MethodRouter::route_layer.
- Merge method routers with MethodRouter::merge
- Customize response for unsupported methods with MethodRouter::fallback
breaking: The default for the type parameter in FromRequest and RequestParts has been removed. Use FromRequest<Body> and RequestParts<Body> to get the previous behavior (#564)
added: FromRequest and IntoResponse are now defined in a new called axum-core. This crate is intended for library authors to depend on, rather than axum itself, if possible. axum-core has a smaller API and will thus receive fewer breaking changes. FromRequest and IntoResponse are re-exported from axum in the same location so nothing is changed for axum users (#564)
breaking: The previously deprecated axum::body::box_body function has been removed. Use axum::body::boxed instead.
fixed: Adding the same route with different methods now works ie .route("/", get(_)).route("/", post(_)).
breaking: routing::handler_method_router and routing::service_method_router has been removed in favor of routing::{get, get_service, ..., MethodRouter}.
breaking: HandleErrorExt has been removed in favor of MethodRouter::handle_error.
breaking: HandleErrorLayer now requires the handler function to be async (#534)
added: HandleErrorLayer now supports running extractors.
breaking: The Handler<B, T> trait is now defined as Handler<T, B = Body>. That is the type parameters have been swapped and B defaults to axum::body::Body (#527)
breaking: Router::merge will panic if both routers have fallbacks. Previously the left side fallback would be silently discarded (#529)
breaking: Router::nest will panic if the nested router has a fallback. Previously it would be silently discarded (#529)
Update WebSockets to use tokio-tungstenite 0.16 (#525)
added: Default to return charset=utf-8 for text content type. (#554)
breaking: The Body and BodyError associated types on the IntoResponse trait have been removed - instead, .into_response() will now always return Response<BoxBody> (#571)
breaking: PathParamsRejection has been renamed to PathRejection and its variants renamed to FailedToDeserializePathParams and MissingPathParams. This makes it more consistent with the rest of axum (#574)
added: Path's rejection type now provides data about exactly which part of the path couldn't be deserialized (#574)

0.3.4 (13. November, 2021)

change: box_body has been renamed to boxed. box_body still exists but is deprecated (#530)

0.3.3 (13. November, 2021)

Implement FromRequest for http::request::Parts so it can be used an extractor (#489)
Implement IntoResponse for http::response::Parts (#490)

0.3.2 (08. November, 2021)

added: Add Router::route_layer for applying middleware that will only run on requests that match a route. This is useful for middleware that return early, such as authorization (#474)

0.3.1 (06. November, 2021)

fixed: Implement Clone for IntoMakeServiceWithConnectInfo (#471)

0.3.0 (02. November, 2021)

Overall:
- fixed: All known compile time issues are resolved, including those with boxed and those introduced by Rust 1.56 (#404)
- breaking: The router's type is now always Router regardless of how many routes or middleware are applied (#404)
  
  This means router types are all always nameable:
```
fn my_routes() -> Router {
    Router::new().route(
        "/users",
        post(|| async { "Hello, World!" }),
    )
}
```
- breaking: Added feature flags for HTTP1 and JSON. This enables removing a few dependencies if your app only uses HTTP2 or doesn't use JSON. This is only a breaking change if you depend on axum with default_features = false. (#286)
- breaking: Route::boxed and BoxRoute have been removed as they're no longer necessary (#404)
- breaking: Nested, Or types are now private. They no longer had to be public because Router is internally boxed (#404)
- breaking: Remove routing::Layered as it didn't actually do anything and thus wasn't necessary
- breaking: Vendor AddExtensionLayer and AddExtension to reduce public dependencies
- breaking: body::BoxBody is now a type alias for http_body::combinators::UnsyncBoxBody and thus is no longer Sync. This is because bodies are streams and requiring streams to be Sync is unnecessary.
- added: Implement IntoResponse for http_body::combinators::UnsyncBoxBody.
- added: Add Handler::into_make_service for serving a handler without a Router.
- added: Add Handler::into_make_service_with_connect_info for serving a handler without a Router, and storing info about the incoming connection.
- breaking: axum's minimum supported rust version is now 1.56
Routing:
- Big internal refactoring of routing leading to several improvements (#363)
  - added: Wildcard routes like .route("/api/users/*rest", service) are now supported.
  - fixed: The order routes are added in no longer matters.
  - fixed: Adding a conflicting route will now cause a panic instead of silently making a route unreachable.
  - fixed: Route matching is faster as number of routes increases.
  - breaking: Handlers for multiple HTTP methods must be added in the same Router::route call. So .route("/", get(get_handler).post(post_handler)) and not .route("/", get(get_handler)).route("/", post(post_handler)).
- fixed: Correctly handle trailing slashes in routes:
  - If a route with a trailing slash exists and a request without a trailing slash is received, axum will send a 301 redirection to the route with the trailing slash.
  - Or vice versa if a route without a trailing slash exists and a request with a trailing slash is received.
  - This can be overridden by explicitly defining two routes: One with and one without a trailing slash.
- breaking: Method routing for handlers has been moved from axum::handler to axum::routing. So axum::handler::get now lives at axum::routing::get (#405)
- breaking: Method routing for services has been moved from axum::service to axum::routing::service_method_routing. So axum::service::get now lives at axum::routing::service_method_routing::get, etc. (#405)
- breaking: Router::or renamed to Router::merge and will now panic on overlapping routes. It now only accepts Routers and not general Services. Use Router::fallback for adding fallback routes (#408)
- added: Router::fallback for adding handlers for request that didn't match any routes. Router::fallback must be use instead of nest("/", _) (#408)
- breaking: EmptyRouter has been renamed to MethodNotAllowed as it's only used in method routers and not in path routers (Router)
- breaking: Remove support for routing based on the CONNECT method. An example of combining axum with and HTTP proxy can be found here (#428)
Extractors:
- fixed: Expand accepted content types for JSON requests (#378)
- fixed: Support deserializing i128 and u128 in extract::Path
- breaking: Automatically do percent decoding in extract::Path (#272)
- breaking: Change Connected::connect_info to return Self and remove the associated type ConnectInfo (#396)
- added: Add extract::MatchedPath for accessing path in router that matched the request (#412)

Error handling:

breaking: Simplify error handling model (#402):

All services part of the router are now required to be infallible.
Error handling utilities have been moved to an error_handling module.
Router::check_infallible has been removed since routers are always infallible with the error handling changes.
Error handling closures must now handle all errors and thus always return something that implements IntoResponse.

With these changes handling errors from fallible middleware is done like so:

use axum::{
    routing::get,
    http::StatusCode,
    error_handling::HandleErrorLayer,
    response::IntoResponse,
    Router, BoxError,
};
use tower::ServiceBuilder;
use std::time::Duration;

let middleware_stack = ServiceBuilder::new()
    // Handle errors from middleware
    //
    // This middleware most be added above any fallible
    // ones if you're using `ServiceBuilder`, due to how ordering works
    .layer(HandleErrorLayer::new(handle_error))
    // Return an error after 30 seconds
    .timeout(Duration::from_secs(30));

let app = Router::new()
    .route("/", get(|| async { /* ... */ }))
    .layer(middleware_stack);

fn handle_error(_error: BoxError) -> impl IntoResponse {
    StatusCode::REQUEST_TIMEOUT
}

And handling errors from fallible leaf services is done like so:

use axum::{
    Router, service,
    body::Body,
    routing::service_method_routing::get,
    response::IntoResponse,
    http::{Request, Response},
    error_handling::HandleErrorExt, // for `.handle_error`
};
use std::{io, convert::Infallible};
use tower::service_fn;

let app = Router::new()
    .route(
        "/",
        get(service_fn(|_req: Request<Body>| async {
            let contents = tokio::fs::read_to_string("some_file").await?;
            Ok::<_, io::Error>(Response::new(Body::from(contents)))
        }))
        .handle_error(handle_io_error),
    );

fn handle_io_error(error: io::Error) -> impl IntoResponse {
    // ...
}

Misc:
- InvalidWebsocketVersionHeader has been renamed to InvalidWebSocketVersionHeader (#416)
- WebsocketKeyHeaderMissing has been renamed to WebSocketKeyHeaderMissing (#416)

fixed: Fix accidental breaking change introduced by internal refactor. BoxRoute used to be Sync but was accidental made !Sync (#273)

0.2.2 (26. August, 2021)

fixed: Fix URI captures matching empty segments. This means requests with URI / will no longer be matched by /:key (#264)
fixed: Remove needless trait bounds from Router::boxed (#269)

0.2.1 (24. August, 2021)

added: Add Redirect::to constructor (#255)

0.2.0 (23. August, 2021)

Overall:
- fixed: Overall compile time improvements. If you're having issues with compile time please file an issue! (#184) (#198) (#220)
- changed: Remove prelude. Explicit imports are now required (#195)

Routing:

added: Add dedicated Router to replace the RoutingDsl trait (#214)
added: Add Router::or for combining routes (#108)
fixed: Support matching different HTTP methods for the same route that aren't defined together. So Router::new().route("/", get(...)).route("/", post(...)) now accepts both GET and POST. Previously only POST would be accepted (#224)
fixed: get routes will now also be called for HEAD requests but will always have the response body removed (#129)
changed: Replace axum::route(...) with axum::Router::new().route(...). This means there is now only one way to create a new router. Same goes for axum::routing::nest. (#215)
changed: Implement routing::MethodFilter via bitflags (#158)
changed: Move handle_error from ServiceExt to service::OnMethod (#160)

With these changes this app using 0.1:

use axum::{extract::Extension, prelude::*, routing::BoxRoute, AddExtensionLayer};

let app = route("/", get(|| async { "hi" }))
    .nest("/api", api_routes())
    .layer(AddExtensionLayer::new(state));

fn api_routes() -> BoxRoute<Body> {
    route(
        "/users",
        post(|Extension(state): Extension<State>| async { "hi from nested" }),
    )
    .boxed()
}

Becomes this in 0.2:

use axum::{
    extract::Extension,
    handler::{get, post},
    routing::BoxRoute,
    Router,
};

let app = Router::new()
    .route("/", get(|| async { "hi" }))
    .nest("/api", api_routes());

fn api_routes() -> Router<BoxRoute> {
    Router::new()
        .route(
            "/users",
            post(|Extension(state): Extension<State>| async { "hi from nested" }),
        )
        .boxed()
}

Extractors:
- added: Make FromRequest default to being generic over body::Body (#146)
- added: Implement std::error::Error for all rejections (#153)
- added: Add OriginalUri for extracting original request URI in nested services (#197)
- added: Implement FromRequest for http::Extensions (#169)
- added: Make RequestParts::{new, try_into_request} public so extractors can be used outside axum (#194)
- added: Implement FromRequest for axum::body::Body (#241)
- changed: Removed extract::UrlParams and extract::UrlParamsMap. Use extract::Path instead (#154)
- changed: extractor_middleware now requires RequestBody: Default (#167)
- changed: Convert RequestAlreadyExtracted to an enum with each possible error variant (#167)
- changed: extract::BodyStream is no longer generic over the request body (#234)
- changed: extract::Body has been renamed to extract::RawBody to avoid conflicting with body::Body (#233)
- changed: RequestParts changes (#153)
  - method new returns an &http::Method
  - method_mut new returns an &mut http::Method
  - take_method has been removed
  - uri new returns an &http::Uri
  - uri_mut new returns an &mut http::Uri
  - take_uri has been removed
- changed: Remove several rejection types that were no longer used (#153) (#154)

Responses:

added: Add Headers for easily customizing headers on a response (#193)
added: Add Redirect response (#192)
added: Add body::StreamBody for easily responding with a stream of byte chunks (#237)
changed: Add associated Body and BodyError types to IntoResponse. This is required for returning responses with bodies other than hyper::Body from handlers. See the docs for advice on how to implement IntoResponse (#86)
changed: tower::util::Either no longer implements IntoResponse (#229)

This IntoResponse from 0.1:

use axum::{http::Response, prelude::*, response::IntoResponse};

struct MyResponse;

impl IntoResponse for MyResponse {
    fn into_response(self) -> Response<Body> {
        Response::new(Body::empty())
    }
}

Becomes this in 0.2:

use axum::{body::Body, http::Response, response::IntoResponse};

struct MyResponse;

impl IntoResponse for MyResponse {
    type Body = Body;
    type BodyError = <Self::Body as axum::body::HttpBody>::Error;

    fn into_response(self) -> Response<Self::Body> {
        Response::new(Body::empty())
    }
}

SSE:

added: Add response::sse::Sse. This implements SSE using a response rather than a service (#98)
changed: Remove axum::sse. It has been replaced by axum::response::sse (#98)

Handler using SSE in 0.1:

use axum::{
    prelude::*,
    sse::{sse, Event},
};
use std::convert::Infallible;

let app = route(
    "/",
    sse(|| async {
        let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
            Event::default().data("hi there!"),
        )]);
        Ok::<_, Infallible>(stream)
    }),
);

Becomes this in 0.2:

use axum::{
    handler::get,
    response::sse::{Event, Sse},
    Router,
};
use std::convert::Infallible;

let app = Router::new().route(
    "/",
    get(|| async {
        let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
            Event::default().data("hi there!"),
        )]);
        Sse::new(stream)
    }),
);

WebSockets:

changed: Change WebSocket API to use an extractor plus a response (#121)
changed: Make WebSocket Message an enum (#116)
changed: WebSocket now uses Error as its error type (#150)

Handler using WebSockets in 0.1:

use axum::{
    prelude::*,
    ws::{ws, WebSocket},
};

let app = route(
    "/",
    ws(|socket: WebSocket| async move {
        // do stuff with socket
    }),
);

Becomes this in 0.2:

use axum::{
    extract::ws::{WebSocket, WebSocketUpgrade},
    handler::get,
    Router,
};

let app = Router::new().route(
    "/",
    get(|ws: WebSocketUpgrade| async move {
        ws.on_upgrade(|socket: WebSocket| async move {
            // do stuff with socket
        })
    }),
);
