Envoy

Serve the web

Envoy is a minimal and pragmatic Rust web application framework built for rapid development. It comes with a robust set of features that make building async web applications and APIs easier and more fun.

Getting started

In order to build a web app in Rust you need an HTTP server, and an async runtime. After running cargo init add the following lines to your Cargo.toml file:

# Example, use the version numbers you need
envoy = "0.16.0"
async-std = { version = "1.8.0", features = ["attributes"] }
serde = { version = "1.0", features = ["derive"] }

Examples

Create an HTTP server that receives a JSON body, validates it, and responds with a confirmation message.

use envoy::Context;
use envoy::prelude::*;

#[derive(Debug, Deserialize)]
struct Animal {
    name: String,
    legs: u16,
}

#[tokio::main]
async fn main() -> envoy::Result {
    let mut app = envoy::new();
    app.at("/orders/shoes").post(order_shoes);
    app.listen("127.0.0.1:8080").await?;
    Ok(())
}

async fn order_shoes(mut ctx: &mut Context) -> envoy::Result {
    let Animal { name, legs } = ctx.body_json().await?;
    Ok(format!("Hello, {}! I've put in an order for {} shoes", name, legs).into())
}
$ curl localhost:8080/orders/shoes -d '{ "name": "Chashu", "legs": 4 }'
Hello, Chashu! I've put in an order for 4 shoes
$ curl localhost:8080/orders/shoes -d '{ "name": "Mary Millipede", "legs": 750 }'
Hello, Mary Millipede! I've put in an order for 750 shoes
