Welcome to the world of seamless Rust application development with Shuttle! This guide will walk you through the process of creating and deploying your Rust app quickly and efficiently. Just like a well-crafted ship that sails smoothly across the waters, let’s navigate through the steps to ensure your Rust application reaches its destination without a hitch.

Features of Shuttle

Shuttle offers some amazing features that make your app building experience fantastic. Here are a few highlights:

• One-line Resource Provisioning: Easily provision resources like a database by merely adding a line of code to your main file. To remove, just delete that line. No need for config YAML files!
• Rapid Development: From initiating a project to deployment, you’re looking at a total of only 4 minutes!
• Framework Support: First-class support for popular Rust frameworks such as Axum, Actix Web, and Rocket.
• Security: Shuttle takes care of security permissions, allowing you to focus on writing great code.

Quick Start Guide

Installation

Install Shuttle on your machine through the following steps:

• For Linux and macOS:

  curl -sSfL https://www.shuttle.rs/install | bash

• For Windows:

  iwr https://www.shuttle.rs/install-win | iex

Initializing Your Project

After installation, run the following command to log in:

cargo shuttle login

Next, initialize your project with:

cargo shuttle init --template axum hello-world

Finally, to deploy your application:

cd hello-world
cargo shuttle project start # Only if not already created during init
cargo shuttle deploy --allow-dirty

Congratulations! Your service named “hello-world” is now running!

A Closer Look at Your Code

Let’s understand your coding experience through an analogy!

Imagine you’re assembling a beautiful ship. The initial code sets the framework of your vessel:

use axum::routing::get, Router;

#[tokio::main]
async fn main() {
    let app = Router::new().route("/", get(hello_world));
    let listener = tokio::net::TcpListener::bind("127.0.0.1:3000").await.unwrap();
    println!("listening on {}", listener.local_addr().unwrap());
    axum::serve(listener, app).await.unwrap();
}

async fn hello_world() -> &'static str {
    "Hello, world!"
}

Here, you’re crafting the hull and deck of your ship. The hello_world function is like the ship’s sail, allowing it to communicate with the world.

Now, to enhance your ship, you utilize Shuttle’s power to add resources like a Postgres database:

#[shuttle_runtime::main]
async fn main(
    #[shuttle_shared_db::Postgres] pool: sqlx::PgPool,
) -> shuttle_axum::ShuttleAxum {
    pool.execute(include_str!("../schema.sql")).await.expect("failed to run migrations");
    let router = Router::new().route("/", get(hello_world));
    Ok(router.into())
}

In this analogy, the database is like a cargo hold, accommodating data and making your ship more powerful and versatile.

Troubleshooting Tips

If you encounter issues while sailing through your development journey, consider these troubleshooting ideas:

• Check installation paths and environment variables to ensure everything is properly configured.
• If you receive errors during deployment, double-check your code and ensure all required packages are included.
• Monitor the logs for any runtime errors—these can often give you clues on what went wrong.
• If you encounter specific bugs or need to request features, don’t hesitate to report them on GitHub.
• For any major confusion, feel free to join our community on Discord.
