Rocket

Build Status Rocket Homepage Current Crates.io Version Matrix: #rocket:mozilla.org IRC: #rocket on chat.freenode.net

Rocket is an async web framework for Rust with a focus on usability, security, extensibility, and speed.

#[macro_use] extern crate rocket;

#[get("/<name>/<age>")]
fn hello(name: String, age: u8) -> String {
    format!("Hello, {} year old named {}!", age, name)
}

#[launch]
fn rocket() -> rocket::Rocket {
    rocket::ignite().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:

The official community support channels are #rocket:mozilla.org on Matrix and the bridged #rocket IRC channel on Freenode at chat.freenode.net. We recommend joining us on Matrix via Element. If your prefer IRC, you can join via the Kiwi IRC client or a client of your own.

Examples

An extensive number of examples are provided in the examples/ directory. Each example can be compiled and run with Cargo. For instance, the following sequence of commands builds and runs the Hello, world! example:

cd examples/hello_world
cargo run

You should see Hello, world! by visiting http://localhost:8000.

Building and Testing

Core and Contrib

The core directory contains the three core libraries: lib, codegen, and http. The contrib directory contains officially supported community contributions and similarly consists of lib and codegen.

Public APIs are exposed via lib packages: core/lib is distributed as the rocket crate while contrib/lib is distributed as the rocket_contrib crate. The remaining crates are implementation details.

Library Testing

Rocket's complete test suite can be run with ./scripts/test.sh from the root of the source tree. The script builds and tests all libraries and examples. It accepts the following flags:

  • --contrib: tests each contrib feature individually
  • --core: tests each core feature individually
  • --release: runs the testing suite in release mode

Additionally, a +${toolchain} flag, where ${toolchain} is a valid rustup toolchain string, can be passed as the first parameter. The flag is forwarded to cargo commands.

To test crates individually, simply run cargo test --all-features in the crate's directory.

Codegen Testing

Code generation diagnostics are tested using trybuild; tests can be found in the codegen/tests/ui-fail directory of both core and contrib. Each test is symlinked into sibling ui-fail-stable and ui-fail-nightly directories which contain the expected error output for stable and nightly compilers, respectively.

Documentation

API documentation is built with ./scripts/mk-docs.sh. The resulting assets are uploaded to api.rocket.rs.

Documentation for a released version ${x} can be found at https://api.rocket.rs/v${x} and https://rocket.rs/v${x}. For instance, the documentation for 0.4 can be found at https://api.rocket.rs/v0.4 and https://rocket.rs/v0.4. Documentation for unreleased versions in branch ${branch} be found at https://api.rocket.rs/${branch} and https://rocket.rs/${branch}. For instance, the documentation for the master branch can be found at https://api.rocket.rs/master and https://rocket.rs/master. Documentation for unreleased branches is updated periodically.

Contributing

Contributions are absolutely, positively welcome and encouraged! Contributions come in many forms. You could:

  1. Submit a feature request or bug report as an issue.
  2. Ask for improved documentation as an issue.
  3. Comment on issues that require feedback.
  4. Contribute code via pull requests.

We aim to keep Rocket's code quality at the highest level. This means that any code you contribute must be:

  • Commented: Complex and non-obvious functionality must be properly commented.
  • Documented: Public items must have doc comments with examples, if applicable.
  • Styled: Your code's style should match the existing and surrounding code style.
  • Simple: Your code should accomplish its task as simply and idiomatically as possible.
  • Tested: You must write (and pass) convincing tests for any new functionality.
  • Focused: Your code should do what it's supposed to and nothing more.

All pull requests are code reviewed and tested by the CI. Note that unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in Rocket by you shall be dual licensed under the MIT License and Apache License, Version 2.0, without any additional terms or conditions.
