v0.8.0

API Documentation

This patch introduces the use of the ? operator in Endpoints, initial support for Server-Sent Events, static file serving, and a new submodule hierarchy. This continues the integration of http-types we started in v0.7.0

Fallible endpoints

Tide now allows the use of ? in endpoints. Errors are automatically converted to tide::Error and have a status code of 500 assigned to them. Overriding status codes can be done through the use of the tide::Status trait which is included in the prelude.

use async_std::{fs, io};
use tide::{Response, StatusCode};

#[async_std::main]
async fn main() -> io::Result<()> {
    let mut app = tide::new();

    app.at("/").get(|_| async move {
        let mut res = Response::new(StatusCode::Ok);
        res.set_body(fs::read("my_file").await?);
        Ok(res)
    });

    app.listen("localhost:8080").await?;
    Ok(())
}

Server-Sent Events

This release makes the first steps towards integrating channels in Tide. In this release we're introducing support for Server-Sent Events, unidirectional event streams that operate over HTTP. This can be used for implementing features such as live-reloading, or sending notifications.

use tide::sse;

#[async_std::main]
async fn main() -> Result<(), std::io::Error> {
    let mut app = tide::new();
    app.at("/sse").get(sse::endpoint(|_req, sender| async move {
        sender.send("fruit", "banana", None).await;
        sender.send("fruit", "apple", None).await;
        Ok(())
    }));
    app.listen("localhost:8080").await?;
    Ok(())
}

Connecting to the stream can be done using async-sse or from the browser:

var sse = new EventSource('/sse');
sse.on("message", (ev) => console.log(ev));

In the future we may expand on these APIs to allow other endpoints to send messages on established channels, but in order to do so we need to implement session management first.

Static file serving

Tide is now able to serve static directories through the Route::serve_dir method. This allows mapping URLs to directories on disk:

#[async_std::main]
async fn main() -> Result<(), std::io::Error> {
    let mut app = tide::new();
    app.at("/public/images").serve_dir("images/")?;
    app.listen("127.0.0.1:8080").await?;
    Ok(())
}

Revamped Hierarchy

Tide has been changing a lot recently, and we've made changes to our submodules so we can keep up. We no longer have a singular middleware submodule and instead split them up by topic. This will allow us to continue to expand on Tide's capabilities, while keeping things easy to find.

Future Directions

The next step for us is to continue to integrate http-types into Tide, focusing on the Request, Response, and Body types. This will likely coincide with a http-types@2.0.0 release. After that our goal is to expand our capabilities around file serving and testing. And finally adding support for WebSockets, sessions, and TLS.

We're excited for the future of Tide, and we're glad you're here with us!

v0.7.0

This patch switches Tide to use http-types for its interface, and async-h1 as its default engine. Additionally we now allow middleware to be defined on a per-route basic. Put together this is effectively an overhaul of Tide's internals, and constitutes a fairly large change.

If you're using Tide in production please be advised this release may have a different stability profile than what you've become used to in the past, and we advice upgrading with appropriate caution. If you find any critical bugs, filing a bug report on one of the issue trackers and reaching out directly over Discord is the quickest way to reach the team.

The reason we're making these changes is that it will allow us to finally polish our error handling story, severely simplify internal logic, and enable many many other features we've been wanting to implement for years now. This is a big step for the project, and we're excited to be taking it together.

Added

• Enables per-route middleware #399
• Added an example for chunked encoding #430

Changed

• Made Endpoint::call generic over the lifetime #397

Fixed

• Fixed a path on the changelog.md #395
• Removed unnecessary internal pin-project call #410

v0.6.0

API Documentation

This patch introduces a new cookies API, based on the excellent
cookie crate. Working with cookies is a staple for
any web server, and Tide's new API now makes this entirely declarative.

Additionally we've added back CORS support. This makes it possible for
possible to configure the single-origin policy of browsers, which is an
incredibly valuable resource.

And finally nesting services with Tide has become even easier. Building on
the APIs in 0.5.0, the manual song-and-dance required to nest APIs is no
longer required, and services can now be nested as-is through the
Route::nest API.

Examples

Cookies

use cookie::Cookie;
use tide::Response;

let mut app = tide::new();

app.at("/").get(|req| async move {
    println!("cat snack: {:?}", req.cookie("snack"));
    Response::new(200)
});
app.at("/set").get(|req| async move {
    let mut res = Response::new(200);
    res.set_cookie(Cookie::new("snack", "tuna"));
    res
});
app.listen("127.0.0.1:8080").await?;

CORS

Make GET, POST, and OPTIONS endpoints on this server accessible from any web
page.

use http::header::HeaderValue;
use tide::middleware::{Cors, Origin};

let rules = Cors::new()
    .allow_methods(HeaderValue::from_static("GET, POST, OPTIONS"))
    .allow_origin(Origin::from("*"))
    .allow_credentials(false);

let mut app = tide::new();
app.middleware(rules);
app.at("/").post(|_| async { Response::new(200) });
app.listen("localhost:8080").await?;

Nesting

Nest the inner serve inside the outer service, exposing GET /cat/nori.

let mut inner = tide::new();
inner.at("/nori").get(|_| async { Response::new(200) });

let mut outer = tide::new();
outer.at("/cat").nest(inner);

outer.listen("localhost:8080").await?;

API Documentation

This fixes a rendering issue on docs.rs.

Fixes

• Fix a rendering issue on docs.rs (#376)

0.5.0

API Documentation

This release introduces the ability to nest applications, add logging
middleware, and improves our documentation.

Nesting applications is a useful technique that can be used to create several
sub-applications. This allows creating clear points of isolation in applications
that can be used completely independently of the main application. But can be
recombined into a single binary if required.

Being able to nest applications is also a necessary first step to re-introduce
per-route middleware, which we'll do in subsequent patches.

Examples

let mut inner = tide::new();
inner.at("/").get(|_| async { "root" });
inner.at("/foo").get(|_| async { "foo" });
inner.at("/bar").get(|_| async { "bar" });

let mut outer = tide::new();
outer
    .at("/nested")
    .strip_prefix() // catch /nested and /nested/*
    .get(inner.into_http_service()); // the prefix /nested will be stripped here

Added

• Added Route::strip_prefix (#364)
• Added the ability Services to be nested (#364)
• Added middleware::RequestLogger (#367)

Changed

• Updated and improved the documentation (#363)

0.4.0

This release is a further polishing of Tide's APIs, and works towards
significantly improving Tide's user experience. The biggest question left
unanswered after this patch is how we want to do error handling, but aside from
that the end-user API should be pretty close to where we want it to be.

The biggest changes in this patch is endpoints now take Request instead of
Context. The new Request and Response types are no longer type aliases but
concrete types, making them substantially easier to use. This also means that
we've been able to fold in all the Ext methods we were exposing, enabling
methods such as let values: Schema = req.body_json()?; to deserialize an
incoming JSON body through a Serde schema. This should make it significantly
easier to write APIs with Tide out of the box.

Example

Create a "hello world" app:

#[async_std::main]
async fn main() -> Result<(), std::io::Error> {
    let mut app = tide::new();
    app.at("/").get(|_| async move { "Hello, world!" });
    app.listen("127.0.0.1:8080").await?;
    Ok(())
}

Redirect from /nori to /chashu:

#[async_std::main]
async fn main() -> Result<(), std::io::Error> {
    let mut app = tide::new();
    app.at("/chashu").get(|_| async move { "meow" });
    app.at("/nori").get(tide::redirect("/chashu"));
    app.listen("127.0.0.1:8080").await?;
    Ok(())
}

Added

• Added logger::RequestLogger based on log (replaces logger:RootLogger).
• Added Request with inherent methods (replaces Context).
• Added Server (replaces App).
• Added Response (replacing a type alias of the same name).
• Added a prelude submodule, holding all public traits.
• Added a new free function, a shorthand for Server::new.
• Added a with_state free function, a shorthand for Server::with_state.
• Added Result type alias (replaces EndpointResult).
• Added a redirect free function to redirect from one endpoint to another.

Changed

• Resolved an #[allow(unused_mut)] workaround.
• Renamed ExtractForms to ContextExt.
• Response is now a newly defined type.

Removed

• Removed logger::RootLogger (replaced by logger:RequestLogger).
• Removed internal use of the box_async macro.
• Removed Context (replaced by Request).
• Removed the Response type alias (replaced by a new Response struct).
• Removed App (replaced by Server).
• Temporarily disabled the multipart family of APIs, improving compilation
  speed by ~30%.
• Removed EndpointResult (replaced by Result).
