Changelog

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

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

Unreleased

[2.2.0] - 2021-03-02

If you use the h1-client, upgrading to this release is reccomended.

Additions

  • h1-client-rustls feature flag, for using the async-h1 client with rustls as the TLS backend.
    • The TLS backend for h1-client is still async-native-tls.
  • Per-request middleware, provided by RequestBuilder::middleware(&mut self, impl Middleware).
  • AsRef<Headers> and AsMut<Headers> for surf::Request and surf::Response.

Fixes

  • Relative redirects should now be handled by the RedirectMiddleware.
  • The h1-client feature should now properly work with http-client 6.3.0+ without additional feature specification.

Docs

  • The http docs now link to the live, up-to-date http_types docs.

Internal

  • Various CI improvements.

[2.1.0] - 2020-10-23

This minor release contains follow-up fixes and improvements to Surf 2.0.

Additions

  • Added a hyper-client cargo feature for enabeling a hyper client backend via http-client.

Fixes

  • Fixed base_url not being propagated to the Client instance in middleware.

Documentation

  • Updated documentation for set_base_url().

[2.0.0] - 2020-10-05

Docs

This major release of Surf contains substantial improvements through a variety of changes and additions.

(Note: this is a cumulative list of changes since Surf 1.0.3)

Notable mentions include:

  • Uses stable standard library futures!
  • Much more type compatibility with Tide via http-types!
  • Re-usable Client which is able to make use of connection pooling under the hood.
  • Reduced generics for Client and Middleware.
  • Re-worked Middleware to use async_trait.

Major Changes

Surf 2 contains some large API changes, as noted here:

http-types

Surf has switched the common backing type interface (surf::http) from the http (hyperium/http) crate to http-types, which covers a larger set of HTTP-related functionality than hyperium/http does, and allows Surf to use the url standard.

This affects any type that came from surf::http, such as StatusCode (old|new), and includes some new patterns, such as Body.

For more information, see this blog post.

Errors

surf::Exception, which was a plain Box<dyn Error + Send + Sync + 'static>, is no more.

Surf now exports a structured surf::Error type, which holds a StatusCode alongside a dynamic error object. Just like anyhow, any error can be cast to this type using the ? operator.

For more information, see this blog post.

Middleware

New middleware:

use surf::middleware::{Middleware, Next};
use surf::{Client, Request, Response, Result};

#[surf::utils::async_trait]
impl Middleware for Logger {
    async fn handle(
        &self,
        req: Request,
        client: Client,
        next: Next<'_>,
    ) -> Result<Response> {
        Ok(res)
    }
}

RequestBuilder

The top-level convenience request methods, surf::get(), surf::post(), etc, now return a RequestBuilder rather than a Request directly. Most RequestBuilder functions have shorthand names: RequestBuilder::body() compared to Request::set_body().

let res = surf::get("http://example.org") // Now returns a `surf::RequestBuilder`!
    .header(a_header, a_value)
    .body(a_body)
    .await?;

Overall usage was kept the same where possible and reasonable, however now a surf::Client must be used when using middleware.

let client = surf::client()
    .with(some_middleware);

let res = client::post(url)
    .header(a_header, a_value)
    .body(a_body)
    .await?;

Alternately:

let client = surf::client()
    .with(some_middleware);

let req = surf::post(url)
    .header(a_header, a_value)
    .body(a_body);
let res = client.send(req).await?;

Mime

Surf has switched from the mime crate to surf::http::Mime from http-types.

For more information, see this blog post.

Additions

  • Switched from hyperium/http to http-types.
  • surf::Request added many methods that exist in tide::Request.
  • surf::Response added many methods that exist in tide::Response.
  • surf::http, an export of http_types, similar to tide::http.
  • surf::middleware::Redirect, a middleware to handle redirect status codes.
  • All conversions for Request and Response between http_types and surf now exist.
  • http_types::{Error, Result} are re-exported as surf::{Error, Result}.
  • A new h1-client feature enables the new async-h1 backend.
  • Transcode responses from non-UTF8 charsets using the on-by-default encoding feature.

Removals

  • Removed native-client feature flag in favor of direct curl-client default.
  • Removed hyper-client feature flag. (Pending re-addition, see: #234)
  • Removed Request::body_string(), Request::body_json(), etc.
    • This functionality is now done via Body, or Client::recv_json(), RequestBuilder::recv_json(), etc.

Changes

  • Updated to use stable futures.
  • wasm-client feature is no longer automatic and must be set via cargo features.
  • All client feature flags are now mutually exclusive. curl-client is the default.
  • surf::method_name "one-off" methods now use a shared client internally if the client is curl-client. (Default)
  • Client::with_http_client() is now generic for any HttpClient rather than taking an Arc<dyn HttpClient>.
    • (The http client is still stored internally as a dynamic pointer.)
  • HttpClient has been upgraded to 6.0, removing Clone from the built in client backends.
  • surf::Request changed many methods to be like those in tide::Request.
  • surf::Response changed many methods to be like those in tide::Response.
  • Surf now uses http-types::mime instead of the mime crate.
  • TryFrom<http_types::Request> for Request is now From<http_types::Request> for Request.
  • surf::Client is no longer generic for C: HttpClient.
  • Middleware now receives surf::Request and returns Result<surf::Response, E>, and no longer requires a generic bound.
  • Middleware now uses async-trait, which is exported as surf::utils::async_trait.
  • The logger middleware is now exported as surf::middleware::Logger. (Note: this middleware is used by default.)
  • surf::{method}() e.g. surf::get() now returns a surf::RequestBuilder rather than a surf::Request.
    • Middleware can no longer be set for individual requests.
    • Instead, use a surf::Client and register middleware via client.with(middleware).
    • Then, send the request from that client via client.send() e.g. let res = client.send(request).await?;.
  • surf::Client now can set a "base url" for that client via client.set_base_url().
  • Client is now built on top of http-client.
  • surf::url has been moved to surf::http::url, with a surf::Url shortcut.

Internal

  • Reduce copies when parsing URLs.
  • Now only depends on futures_util rather than all of futures.
  • wasm-client now has proper headless browser CI testing.
  • Use Clippy in CI.
  • Set up an MSRV in CI.
  • Stop hitting the network when running tests.

Changes since 2.0.0-alpha.7

  • Added: RequestBuilder now has a .query() function for setting structured querystrings.
  • Changed: Client::send() and RequestBuilder::send() are now plain async functions and no longer return BoxFutures.
  • Changed: surf::url has been moved to surf::http::url, with a surf::Url shortcut.

[2.0.0-alpha.7] - 2020-09-29

Fixes

  • Downgrade rust_2018_idioms from forbid to warn for compilation with newer deps.

[2.0.0-alpha.6] - 2020-09-27

This is an alpha release in preparation of 2.0.0, so you can start using Surf with stable futures. The aim is for this to be the last 2.0 alpha release.

As of this release, surf::get(), surf::post(), etc, now use a globally shared client internally, allowing for easier access to optimizations such as connection pooling.

Removals

  • Removed native-client feature flag in favor of direct curl-client default.

Changes

  • wasm-client feature is no longer automatic and must be set via cargo features.
  • All client feature flags are now mutually exclusive. curl-client is the default.
  • surf::method_name "one-off" methods now use a shared client internally if the client is curl-client. (Default)
  • Client::with_http_client() is now generic for any HttpClient rather than taking an Arc<dyn HttpClient>.
    • (The http client is still stored internally as a dynamic pointer.)
  • HttpClient has been upgraded to 6.0, removing Clone from the built in client backends.

Fixes

  • Surf can once again build with --no-default-features (and no client).
  • Doc updates

Internal

  • wasm-client now has proper headless browser CI testing.

[2.0.0-alpha.5] - 2020-09-07

This is an alpha release in preparation of 2.0.0, so you can start using Surf with stable futures. There may be significant breaking changes before the final 2.0 release. Until thin, we recommend pinning to the particular alpha:

[dependencies]
surf = "= 2.0.0-alpha.5"

This alpha release notably contains much more API parity with Tide, particularly for surf::Request, surf::Response, and surf::middleware::Middleware. Middleware also is now implemented using async-trait. Additionally, surf::Client is no longer generic and now instead holds the internal HttpClient as a dynamic trait object.

These changes mean that surf middleware must undergo the following changes:

Old middleware:

impl<C: HttpClient> Middleware<C> for Logger {
    fn handle<'a>(
        &'a self,
        req: Request,
        client: C,
        next: Next<'a, C>,
    ) -> BoxFuture<'a, Result<Response, http_types::Error>> {
        Box::pin(async move {
            Ok(res)
        })
    }
}

New middleware:

#[surf::utils::async_trait]
impl Middleware for Logger {
    async fn handle(
        &self,
        req: Request,
        client: Client,
        next: Next<'_>,
    ) -> Result<Response> {
        Ok(res)
    }
}

This alpha release also contains large changes to how the surf::Request and surf::Client APIs are structured, adding a surf::RequestBuilder which is now returned from methods such as surf::get(...). Overall usage structure was kept the same where possible and reasonable, however now a surf::Client must be used when using middleware.

let client = surf::client()
    .with(some_middleware);

let req = surf::post(url) // Now returns a `surf::RequestBuilder`!
    .header(a_header, a_value)
    .body(a_body);
let res = client.send(req).await?;

Additions

  • surf::Request added many methods that exist in tide::Request.
  • surf::Response added many methods that exist in tide::Response.
  • surf::http, an export of http_types, similar to tide::http.
  • surf::middleware::Redirect, a middleware to handle redirect status codes.
  • All conversions for Request and Response between http_types and surf now exist.

Changes

  • surf::Request changed many methods to be like those in tide::Request.
  • surf::Response changed many methods to be like those in tide::Response.
  • Surf now uses http-types::mime instead of the mime crate.
  • TryFrom<http_types::Request> for Request is now From<http_types::Request> for Request.
  • surf::Client is no longer generic for C: HttpClient.
  • Middleware now receives surf::Request and returns Result<surf::Response, E>, and no longer requires a generic bound.
  • Middleware now uses async-trait, which is exported as surf::utils::async_trait.
  • The logger middleware is now exported as surf::middleware::Logger. (Note: this middleware is used by default.)
  • surf::{method}() e.g. surf::get() now returns a surf::RequestBuilder rather than a surf::Request.
    • Middleware can no longer be set for individual requests.
    • Instead, use a surf::Client and register middleware via client.with(middleware).
    • Then, send the request from that client via client.send() e.g. let res = client.send(request).await?;.
  • surf::Client now can set a "base url" for that client via client.set_base_url().

Fixes

  • From<http_types::Request> for Request now properly propagates all properties.
  • A cloned surf::Client no longer adds middleware onto its ancestor's middleware stack.
  • Some feature flags are now correct.

Internal

  • Use Clippy in CI.
  • Improved examples.
  • Now only depends on futures_util rather than all of futures.
