Deploying to Cloudflare Workers?

[maxcountryman]

Hi folks, with the news that Cloudflare Workers now supports Rust directly I'm curious what would be required to deploy a Tide app to this surface?

I believe there's some prior art involving AWS Lambda but I'm not sure if that's applicable here.

It can work as long as you disable sse and tcp_listener module, which used task::spawn which is not available on wasm platform for async-std.

You can use the tide::Server::respond method to convert from worker::Request and into worker::Response.
One thing you might be careful is that the worker::Request take js_sys::Uint8Array as body input, so you need to serde_json::to_vec, convert vec![] to Uint8Array and convert array into JsValue so that it can send to other worker endpoints, such as durable_object.

my demo repo
As you can see, I get it working for both worker and durable-object which both are powered by tide and async-graphql.
