Add this to your Cargo.toml:

toml [dependencies] routerify = "3" routerify-json-response = "3"

Example

```rust use hyper::{Body, Request, Response, Server, StatusCode}; // Import required routerifyjsonresponse methods. use routerifyjsonresponse::{jsonfailedrespwithmessage, jsonsuccessresp}; use routerify::{Router, RouterService}; use std::net::SocketAddr;

async fn listusershandler(: Request) -> Result, routerifyjson_response::Error> { // Fetch response data from somewhere. let users = ["Alice", "John"];

// Generate a success JSON response with the data in the following format:
// { "status": "success", code: 200, data: ["Alice", "John"] }
json_success_resp(&users)

}

async fn listbookshandler(: Request) -> Result, routerifyjsonresponse::Error> { // Generate a failed JSON response in the following format: // { "status": "failed", code: 500, data: "Internal Server Error: Couldn't fetch book list from database" } jsonfailedrespwithmessage( StatusCode::INTERNALSERVER_ERROR, "Couldn't fetch book list from database", ) }

// Create a router. fn router() -> Router { Router::builder() // Attach the handlers. .get("/users", listusershandler) .get("/books", listbookshandler) .build() .unwrap() }

[tokio::main]

async fn main() { let router = router();

// Create a Service from the router above to handle incoming requests.
let service = RouterService::new(router).unwrap();

// The address on which the server will be listening.
let addr = SocketAddr::from(([127, 0, 0, 1], 3001));

// Create a server by passing the created service to `.serve` method.
let server = Server::bind(&addr).serve(service);

println!("App is running on: {}", addr);
if let Err(err) = server.await {
    eprintln!("Server error: {}", err);
}

} ```
