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::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:
|
|
|
|
* [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".

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:
|
|
|
|
```sh
|
|
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.
|
|
|
|
[`trybuild`]: https://docs.rs/trybuild/1
|
|
|
|
## Documentation
|
|
|
|
API documentation is built with `./scripts/mk-docs.sh`. The resulting assets are
|
|
uploaded to [api.rocket.rs](https://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.

|
|
|
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.
