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 + +```rust +use async_std::task; + +fn main() -> Result<(), std::io::Error> { + task::block_on(async { + let mut app = tide::new(); + app.at("/").get(|_| async move { "Hello, world!" }); + app.listen("127.0.0.1:8080").await?; + Ok(()) + }) +} +``` + ### Added -- Added `logger::RequestLogger` based on `log` (replaces `logger:RootLogger`) +- 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`). ### 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 `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`). ## [0.3.0] - 2019-10-31 @@ -34,7 +78,9 @@ were right before splitting up the crate.

To -/// add middleware to an app, use the [`App::middleware`] method. -/// -/// # Hello, world! -/// -/// You can start a simple Tide application that listens for `GET` requests at path `/hello` -/// on `127.0.0.1:8000` with: -/// -/// ```rust, no_run -/// -/// let mut app = tide::App::new(); -/// app.at("/hello").get(|_| async move {"Hello, world!"}); -/// app.run("127.0.0.1:8000").unwrap(); -/// ``` -/// -/// # Routing and parameters -/// -/// Tide's routing system is simple and similar to many other frameworks. It -/// uses `:foo` for "wildcard" URL segments, and `*foo` to match the rest of a -/// URL (which may include multiple segments). Here's an example using wildcard -/// segments as parameters to endpoints: -/// -/// ```rust, no_run -/// use tide::error::ResultExt; -/// -/// async fn hello(cx: tide::Context<()>) -> tide::EndpointResult { -/// let user: String = cx.param("user").client_err()?; -/// Ok(format!("Hello, {}!", user)) -/// } -/// -/// async fn goodbye(cx: tide::Context<()>) -> tide::EndpointResult { -/// let user: String = cx.param("user").client_err()?; -/// Ok(format!("Goodbye, {}.", user)) -/// } -/// -/// let mut app = tide::App::new(); -/// -/// app.at("/hello/:user").get(hello); -/// app.at("/goodbye/:user").get(goodbye); -/// app.at("/").get(|_| async move { -/// "Use /hello/{your name} or /goodbye/{your name}" -/// }); -/// -/// app.run("127.0.0.1:8000").unwrap(); -/// ``` -/// -/// You can learn more about routing in the [`App::at`] documentation. -/// -/// # Application state -/// -/// ```rust, no_run -/// -/// use http::status::StatusCode; -/// use serde::{Deserialize, Serialize}; -/// use std::sync::Mutex; -/// use tide::{error::ResultExt, response, App, Context, EndpointResult}; -/// -/// #[derive(Default)] -/// struct Database { -/// contents: Mutex>, -/// } -/// -/// #[derive(Serialize, Deserialize, Clone)] -/// struct Message { -/// author: Option, -/// contents: String, -/// } -/// -/// impl Database { -/// fn insert(&self, msg: Message) -> usize { -/// let mut table = self.contents.lock().unwrap(); -/// table.push(msg); -/// table.len() - 1 -/// } -/// -/// fn get(&self, id: usize) -> Option { -/// self.contents.lock().unwrap().get(id).cloned() -/// } -/// } -/// -/// async fn new_message(mut cx: Context) -> EndpointResult { -/// let msg = cx.body_json().await.client_err()?; -/// Ok(cx.state().insert(msg).to_string()) -/// } -/// -/// async fn get_message(cx: Context) -> EndpointResult { -/// let id = cx.param("id").client_err()?; -/// if let Some(msg) = cx.state().get(id) { -/// Ok(response::json(msg)) -/// } else { -/// Err(StatusCode::NOT_FOUND)? -/// } -/// } -/// -/// fn main() { -/// let mut app = App::with_state(Database::default()); -/// app.at("/message").post(new_message); -/// app.at("/message/:id").get(get_message); -/// app.run("127.0.0.1:8000").unwrap(); -/// } -/// ``` - -#[allow(missing_debug_implementations)] -pub struct App { - router: Router, - middleware: Vec>>, - state: State, -} - -impl App<()> { - /// Create an empty `App`, with no initial middleware or configuration. - pub fn new() -> App<()> { - Self::with_state(()) - } -} - -impl Default for App<()> { - fn default() -> App<()> { - Self::new() - } -} - -impl App { - /// Create an `App`, with initial middleware or configuration. - pub fn with_state(state: State) -> App { - App { - router: Router::new(), - middleware: Vec::new(), - state, - } - } - - /// Add a new route at the given `path`, relative to root. - /// - /// Routing means mapping an HTTP request to an endpoint.
