base on A web framework for Rust. # Rocket [](https://github.com/rwf2/Rocket/actions) [](https://rocket.rs) [](https://crates.io/crates/rocket) [](https://chat.mozilla.org/#/room/#rocket:mozilla.org) Rocket is an async web framework for Rust with a focus on usability, security, extensibility, and speed. ```rust #[macro_use] extern crate rocket; #[get("/<name>/<age>")] fn hello(name: &str, age: u8) -> String { format!("Hello, {} year old named {}!", age, name) } #[launch] fn rocket() -> _ { rocket::build().mount("/hello", routes![hello]) } ``` Visiting `localhost:8000/hello/John/58`, for example, will trigger the `hello` route resulting in the string `Hello, 58 year old named John!` being sent to the browser. If an `<age>` string was passed in that can't be parsed as a `u8`, the route won't get called, resulting in a 404 error. ## Documentation Rocket is extensively documented: * [Overview]: A brief look at what makes Rocket special. * [Quickstart]: How to get started as quickly as possible. * [Getting Started]: How to start your first Rocket project. * [Guide]: A detailed guide and reference to Rocket. * [API Documentation]: The "rustdocs". [Quickstart]: https://rocket.rs/guide/quickstart [Getting Started]: https://rocket.rs/guide/getting-started [Overview]: https://rocket.rs/overview/ [Guide]: https://rocket.rs/guide/ [API Documentation]: https://api.rocket.rs Documentation for the `master` branch is available at https://rocket.rs/master and https://api.rocket.rs/master. Documentation for major release version `${x}` is available at `https://[api.]rocket.rs/v${x}`. For example, the v0.4 docs are available at https://rocket.rs/v0.4 and https://api.rocket.rs/v0.4. Finally, API docs for active git branches are available at `https://api.rocket.rs/${branch}`. For example, API docs for the `master` branch are available at https://api.rocket.rs/master. Branch rustdocs are built and deployed on every commit. ## Examples The [examples](examples#readme) directory contains complete crates that showcase Rocket's features and usage. Each example can be compiled and run with Cargo. For instance, the following sequence of commands builds and runs the `hello` example: ```sh cd examples/hello cargo run ``` ## Getting Help If you find yourself needing help outside of the documentation, you may: * Ask questions via [GitHub discussions questions]. * Chat with us at [`#rocket:mozilla.org`] on Matrix (join [via Element]).
