This crate uses #![forbid(unsafe_code)]
to ensure everything is implemented in 100% safe Rust.
use std::error::Error;
use async_graphql::{http::GraphiQLSource, EmptyMutation, EmptySubscription, Object, Schema};
use async_graphql_poem::*;
use poem::{listener::TcpListener, web::Html, *};
struct Query;
#[Object]
impl Query {
async fn howdy(&self) -> &'static str {
"partner"
}
}
#[handler]
async fn graphiql() -> impl IntoResponse {
Html(GraphiQLSource::build().finish())
}
#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
// create the schema
let schema = Schema::build(Query, EmptyMutation, EmptySubscription).finish();
// start the http server
let app = Route::new().at("/", get(graphiql).post(GraphQL::new(schema)));
println!("GraphiQL: http://localhost:8000");
Server::new(TcpListener::bind("0.0.0.0:8000"))
.run(app)
.await?;
Ok(())
}
Requires the dynamic-schema
feature to be enabled.

One of the tools used to monitor your graphql server in production is Apollo Studio. Apollo Studio is a cloud platform that helps you build, monitor, validate, and secure your organization's data graph.
Add the extension crate async_graphql_apollo_studio_extension
to make this avaliable.
