• v0.15.0 Changes

  November 13, 2020

  This patch adds Server::bind, SessionMiddleware::with_cookie_domain, and a new optional cookies feature.

  Server::bind

  Tide v0.15.0 introduces a new way to start servers: Server::bind. This enables separatining "open the socket" from "start accepting connections" which Server::listen does for you in a single call.

  🔀 This was introduced as a way to enable users to log messages after ports were successfully opened. But it can also be used to synchronize server initialization. For example: your application may want to connect to a database, a cache, and open an HTTP connection. With Server::bind you can start the connection, but wait to handle inbound traffic until all other components of the server have started up.

  🔊 When Server::bind is called, it returns an instance of Listener which is able to return information on all ports that are being listened on. By default Server::listen logs these out, but when manually calling Server::bind you get control on how to log this info.

  👀 For now ListenInfo only includes a few basics such as the address that's being listened on, and whether the connection is encrypted. But as we seek to stabilize and integrate tide-rustls into tide, we may include more info on the encryption settings. And perhaps in the future we'll include more information on the server's routes too. But for now this serves as an entry point for all that.

  use tide::prelude::\*;let mut app = tide::new(); app.at("/").get(|\_| async { Ok("Hello, world!") });let mut listener = app.bind("127.0.0.1:8080").await?;for info in listener.info().iter() { println!("Server listening on {}", info); } listener.accept().await?;
  

  SessionMiddleware::with_cookie_domain

  Our session middleware now supports a with_cookie_domain method to scope a cookie to a specific domain. We already support various cookie options when constructing the session middleware, and now we support scoping the domain as well.

  let SECRET = b"please do not hardcode your secret";let mut app = tide::new(); app.with(SessionMiddleware::new(MemoryStore::new(), SECRET) .with\_cookie\_name("custom.cookie.name") .with\_cookie\_path("/some/path") .with\_cookie\_domain("www.rust-lang.org") // This is new. .with\_same\_site\_policy(SameSite::Lax) .with\_session\_ttl(Some(Duration::from\_secs(1))) .without\_save\_unchanged(), );
  

  http-types typed headers

  🚀 We've been doing a lot of work on typed headers through http-types, which is the HTTP library underpinning both tide and surf. We're getting close to being done implementing all of the specced HTTP Headers, and will then move to integrate them more closely into Tide. You can find the release notes for http-types here.

• v0.14.0 Changes

  October 16, 2020

  📚 Documentation

  🛠 This patch introduces a several feature flags to opt-out of dependencies, a reworked rustdoc landing page, and a variety of bug fixes. Over the past few months we've been hard at work on Surf v2.0.0, and have made a lot of progress on http-types' typed headers. We hope to start bringing some of this work over into Tide soon.

  Behind the scenes we're also hard at work at improving our processes. Both Tide and the wider http-rs project have really taken off, and our biggest challenge in ensuring we correctly prioritize, communicate, and empower people who want to get involved. We don't have specifics we can share yet, but it's something we're actively working on with the team. Because as Tide and http-rs grow, so must our processes.

• v0.13.0 Changes

  July 31, 2020

  📄 Docs

  🚀 This release introduces first-class support for sessions, fixes a
  0️⃣ long-standing bug with our default middleware, clarifies our stability
  guarantees, and renamed the API to register middleware through.

  Sessions

  👍 We're excited to announce initial support for sessions in Tide. This feature
  enables Tide applications to associate multiple separate requests as
  🏗 belonging to the same origin. Which is a pre-requisite to build common
  🌐 web-app features such as user accounts, multi-request transactions, and
  channels.

  🏗 Tide sessions are generic over backend stores and signing strategy. It builds
  🚀 on the newly released async-session
  📄 2.0.0 library, which is a set of common
  traits that types that make up a session. But beyond that, much of it is
  implementation specific.

  0️⃣ Tide ships with a memory and cookie store by default. However we have
  also published several convenient session store implementations for common
  databases, providing a nice selection to choose from:

  • Memory Session (shipped with Tide)
  • Cookie Session (shipped with Tide)
  • 📄 async-sqlx-session (SQLite only for now; we hope to support more)
  • 📄 async-redis-session
  • 📄 async-mongodb-session

  Using "Redis" as the backing session store for Tide is as easy as writing 3
  lines and including a dependency in your Cargo.toml:

  use async\_redis\_session::RedisSessionStore;use tide::sessions::SessionMiddleware;use tide::{Redirect, Request}; #[async\_std::main]async fn main() -\> tide::Result\<()\> { let mut app = tide::new(); // Create a Redis-backed session store and use it in the applet store = RedisSessionStore::new("redis://127.0.0.1:6379")?; let secret = std::env::var("SESSION\_SECRET").unwrap(); app.with(SessionMiddleware::new(store, secret.as\_bytes())); app.at("/").get(|mut req: Request\<()\>| async move { // Store a counter in the session; increment it by one on each visitlet session = req.session\_mut(); let visits: usize = session.get("visits").unwrap\_or\_default(); session.insert("visits", visits + 1).unwrap(); // Render a page that shows the number of requests made in the sessionlet visits: usize = req.session().get("visits").unwrap(); Ok(format!("you have visited this website {} times", visits)) }); // Close the current session app.at("/reset").get(|mut req: Request\<()\>| async move { req.session\_mut().destroy(); Ok(Redirect::new("/")) }); // Start the server app.listen("127.0.0.1:8080").await?; Ok(()) }
  

  It's still early for Tide sessions. But we're incredibly excited for how
  convenient it already is, and excited for the possibilities this will enable!

  Renaming Server::middleware to Server::with

  This patch renames Server::middleware to Server::with in order to
  streamline much of the middleware APIs.

  // After this patchlet mut app = tide::new(); app.with(MyMiddleware::new()); app.at("/").get(|\_| async move { Ok("hello chashu") }); app.listen("localhost:8080").await?;// Before this patchlet mut app = tide::new(); app.middleware(MyMiddleware::new()); app.at("/").get(|\_| async move { Ok("hello chashu") }); app.listen("localhost:8080").await?;
  

  A small change, but ever so convenient.

  🌲 No more duplicate log messages

  0️⃣ Ever since we introduced application nesting we've had issues with default
  🛠 middleware running twice. This patch fixes that for our logging middleware in
  two ways:

  0️⃣ 1. We've introduced a logger Cargo feature to disable the default logging middleware #661

  1. We now track calls to the logger inside the state map to ensure
     it's only called once per app #662

  ⚡️ There may be room to optimize this further in the future, and perhaps extend
  the same mechanisms to work for more built-in middleware. But for now this
  patch resolves the most common issues people were reporting.

  Clarification on stability

  🚀 Tide has been deployed to production in many places: independent authors
  🏗 taking control of their publishing pipelines, software professionals building
  internal tooling, and enterprises running it in key parts of their
  infrastructure.

  🚀 In past Tide releases shipped with a warning that actively recommended
  🚑 against using it in any critical path. However we've chosen to no longer
  🚀 include that warning starting this release. Much of the work at the protocol
  layer and below has completed, and we've received positive reports on how it
  performs.

  For the foreseable future Tide will remain on the 0.x.x semver range. While
  we're confident in our foundations, we want to keep iterating on the API.
  🚀 Once we find that work has slowed down we may decide when to release a 1.0.0
  🚀 release.

  ➕ Added

  • ➕ Added From<StatusCode> for Response #650
  • ➕ Added a feature-flag to disable the default logger middleware #661
  • ➕ Added impl Into<Request> for http_types::Request #670

• v0.12.0 Changes

  July 17, 2020

  📄 Docs

  🚀 This release includes 35 PRs merged over the course of the last month. Most
  notably we've streamlined how errors are propagated inside middleware,
  👯 introduced a new ResponseBuilder type, State must now be Clone, and we
  are introducing an extensible API for Server::listen.

  ResponseBuilder

  Returning responses from endpoints is often different from operating on
  response in middleware. In order to make it easier for people to author
  responses we're introducing tide::ResponseBuilder in this patch!

  🏗 You can create a new response builder by calling Response::builder and
  passing it a status code. This enables writing some really concise endpoints:

  app.at("/").get(|\_| async { let res = Response::builder(203) .body(json!({ "hello": "cats!" })) .header("X-Nori", "me-ow") .header("X-Chashu", "meewwww"); Ok(res) })
  

  This sets Tide up really nicely for the future too; once we have async
  closures, and a resolution for Ok-wrapping (fingers crossed) this will be
  even more concise. We're excited for developments in the language!

  Server listen

  👍 Tide now supports extensions for
  App::listen. This patch introduces a new Listener trait that is
  implemented for std types such as TcpStream, SocketAddr and
  UnixStream. But can also be implemented by users of Tide to provide custom
  transports.

  👍 In particular, what this enables us to do is to start trialing TLS support in
  external crates. We'll soon have
  tide-rustls available as an external
  🏗 crate that will enable building TLS-terminating Tide servers:

  let mut app = tide::new();let listener = TlsListener::build() .addrs("localhost:4433") .cert(cert) .key(key); app.listen(listener).await?;
  

  In addition we're shipping tide::listener::ConcurrentListener, a convenient
  constructor to have a single server respond to incoming requests from
  multiple transports. For example, some applications may want to listen on
  both IPv4 and IPv6. With ConcurrentListener that's possible:

  use std::net::{Ipv4Addr, Ipv6Addr};use tide::listener;let mut app = tide::new();let mut listener = listener::ConcurrentListener::new(); listener.add((Ipv4Addr::new(127, 0, 0, 1), 8000)); listener.add((Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 8000)); app.listen(listener).await?;
  

  👯 State must be Clone

  One problem we had for a while was that when manually nesting or
  parallelizing applications, State would be wrapped in an Arc multiple
  times. In this patch we're solving that by providing people with more control
  👯 around how State is shared by requiring State to implement Clone.

  👯 In most existing applications State can be made Clone by manually
  wrapping it in an Arc::new. But it's also possible to wrap individual
  👯 fields in an Arc and deriving `Clone for the whole struct, as we did in one
  of our examples:

  // Example state before this patch.struct State { users: RwLock\<Vec\<User\>\>, }// Example state after this patch.#[derive(Clone)]struct State { users: Arc\<RwLock\<Vec\<User\>\>\>, }
  

  There is no right answer how to structure State; but we wanted to enable
  people to factor it in the way that makes most sense for their applications.

  Using of async-trait

  We've migrated all of our traits to use async-trait. This should make it easier to author Middleware implementations. For convenience Tide re-exports as tide::utils::async_trait.

  🔄 Changes in middleware error handling

  Before this patch, calling next().await? in middleware would return a
  Result<Response>. The idea was that the Err variant could freely be
  thrown up the middleware stack, and transformed into a Response at the top
  of the stack. However in practice this didn't turn out great: middleware such
  as CORS needed to manipulate the Err path to ensure the right headers were
  set. And we didn't provide an interface for this.

  So instead this patch changes the way we handle errors in middleware. We
  still enable ? to be used inside middleware, but between each middleware we
  convert Result<Response, tide::Error> into a Response, and if an error
  occurred, we populate the newly introduced Response::error field.

  This means that middleware can always assume there is a valid Response
  coming through, and no longer needs to check both Ok and Err branch
  returned by next().await. An example:

  /// Before this patch: need to check both branches.async fn my\_middleware\<State\>(req: Request\<State\>, next: Next) -\> Result\<Response\> { println!("before"); match next().await { Err(err) =\> { println!("status code {}", err.status()); Err(err) } Ok(res) =\> { println!("status code {}", res.status()); Ok(res) } } }/// With this patch: there's only a single branch to operate on.async fn my\_middleware\<State\>(req: Request\<State\>, next: Next) -\> Result\<Response\> { println!("before"); let res = next().await; println!("status code {}", res.status()); Ok(res) }
  

  Note: neither of these examples will quite compile until we have async
  closures, but it serves to illustrate the point.

• v0.9.0 Changes

  May 23, 2020

  ⚡️ This patch updates http-types to 2.0.0, removes http-service in favor of
  Server::respond, and adds an all-new Redirect struct.

  http-types 2.0

  🚀 Read the http-types changelog for a full rundown of changes. But the biggest change for Tide is that working with headers in Tide is becoming a lot easier. To see all the changes in action, compare what it was like to compare a header with how it is now:

  // http-types 1.xassert\_eq!(req.header(&"X-Forwarded-For".parse().unwrap()), Some(&vec!["127.0.0.1".parse().unwrap()]));// http-types 2.xassert\_eq!(req.header["X-Forwarded-For"], "127.0.0.1");
  

  Constructing headers from string literals, comparing to string literals,
  using [] to access by name — this should make it much easier to work with
  Tide!

  Server::respond

  http-service has been a tricky one. It originally served as a simplified wrapper around hyperium/hyper with a streaming Body type with the potential to abstract to other backends as well. But as we've evolved Tide and the http-rs ecosystem, we found http-service becoming more a hurdle than a help.

  ✅ In this patch we're removing http-service from Tide and introducing Server::respond as its replacement. This not only makes Tide easier to maintain, it makes it easier to use with any other backend than ever before. It also provides convenient way to unit test Tide apps as well:

  use tide::http::{self, Url, Method}; #[async\_std::test]async fn hello\_world() -\> tide::Result\<()\> { let mut app = tide::new(); app.at("/").get(|\_| async move { Ok("hello world")} ); let req = http::Request(Method::Get, Url::parse("http://computer.soup")?); let res = app.respond(req).await?; assert\_eq!(res.body\_string().await?, "hello world".to\_owned()); Ok(()) }
  

  Redirect

  In the past we introduced the redirect submodule which provided redirect endpoints. And Response::redirect* which provided methods to create redirects inside endpoints. In this patch we're removing those APIs in favor of tide::Redirect which can be used both to create new redirect endpoint, and be used inside existing endpoints to redirect:

  use tide::Redirect; #[async\_std::main]async fn main() -\> tide::Result\<()\> { let mut app = tide::new(); app.at("/fish").get(|\_| async move { Ok("yum") }); // Either create a redirect endpoint directly. app.at("/chashu").get(Redirect::new("/fish")); // Or redirect from inside an existing endpoint// enabling conditional redirects. app.at("/nori").get(|\_| async move { Redirect::new("/fish") }); app.listen("127.0.0.1:8080").await?; Ok(()) }
  

  Big thanks to @ethanboxx for introducing this pattern to Tide. We'll be looking to introduce this pattern to more APIs in the future.

  📚 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 [email protected] 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 Changes

  April 17, 2020

  📄 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.
