cloudflare-whiteboard

I'm feeling stressed, so I thought building a little toy project might make me feel better

Setup

Go ahead and install rust, via rustup. Then grab cargo-generate. Once those are installed you can run the skeleton

=> cargo-generate

=> rustup

setup by using $ cargo generate cloudflare/workers-rs. I chose the axum skeleton, just because the routing is a little more structured than

the raw http examples.

Verify the setup by using npx wrangler build or install via npm install wrangler@latest

You should be able to hit 'b' to open in browser

Starting

So let's dig into the lib.rs folder, start by adding a pattern for handling multiple routes.

use axum::{routing::get, Router, response::IntoResponse};
use tower_service::Service;
use worker::*;


pub async fn root() -> &'static str {
    "Hello Axum!"
}

async fn health() -> impl IntoResponse {
    r#"{"Ok"}"#
}

pub fn app_router() -> Router {
    Router::new()
        .route("/", get(root))
}

fn health_router() -> Router {
    Router::new() 
        .route("/health", get(health))
}


fn router() -> Router {
    let routes =
        Router::new()
            .merge(app_router())
            .merge(health_router());
    return routes
}

#[event(fetch)]
async fn fetch(
    req: HttpRequest,
    _env: Env,
    _ctx: Context,
) -> Result> {
    console_error_panic_hook::set_once();
    Ok(router().call(req).await?)
}

Obviously its just a start. Going to revisit later
