Rocket
Rocket is a web framework for Rust that makes writing fast, secure web applications simple without sacrificing flexibility, usability, or type safety.
Rocket is type-safe, which means that many kinds of errors are caught at compile time. Rocket is also fast, with a focus on performance and speed.
Rocket is secure, with built-in support for common security vulnerabilities. Rocket is flexible, with a powerful routing system that allows you to define routes using a simple, intuitive syntax.
Rocket is also easy to use, with a clean, well-documented API that makes it easy to start.
Let's look at how to get started with Rocket and build a simple web application.
Getting Started
Create a new Rust project using Cargo, enter the project directory, and open the project in your favorite code editor.
cargo new hello-rocket
cd hello-rocket
code .
Add the Rocket crate to your Cargo.toml file.
[dependencies]
rocket = "0.5.1"
Then, replace the content of src/main.rs with the following code.
#[macro_use] extern crate rocket;
#[get("/")]
fn index() -> &'static str {
"Hello, Rocket 🚀"
}
#[launch]
fn rocket() -> _ {
rocket::build().mount("/", routes![index])
}
Now you can run the application using the following command.
cargo run
And you should see the following output.
Now visit http://localhost:8000 in your web browser, and you should see the following message.
That's it! You've just built a simple web application using Rocket.
