 - **Performance:** This has huge performance implications: Leptos is simply much faster at both creating and updating the UI than Yew is.
 - **Server integration:** Yew was created in an era in which browser-rendered single-page apps (SPAs) were the dominant paradigm. While Leptos supports client-side rendering, it also focuses on integrating with the server side of your application via server functions and multiple modes of serving HTML, including out-of-order streaming.
 
-- ### How is this different from Dioxus?
+### How is this different from Dioxus?
 
 Like Leptos, Dioxus is a framework for building UIs using web technologies. However, there are significant differences in approach and features.
 
 - **VDOM vs. fine-grained:** While Dioxus has a performant virtual DOM (VDOM), it still uses coarse-grained/component-scoped reactivity: changing a stateful value reruns the component function and diffs the old UI against the new one. Leptos components use a different mental model, creating (and returning) actual DOM nodes and setting up a reactive system to update those DOM nodes.
 - **Web vs. desktop priorities:** Dioxus uses Leptos server functions in its fullstack mode, but does not have the same `<Suspense>`-based support for things like streaming HTML rendering, or share the same focus on holistic web performance. Leptos tends to prioritize holistic web performance (streaming HTML rendering, smaller WASM binary sizes, etc.), whereas Dioxus has an unparalleled experience when building desktop apps, because your application logic runs as a native Rust binary.

 Sycamore and Leptos are both heavily influenced by SolidJS. At this point, Leptos has a larger community and ecosystem and is more actively developed. Other differences:

-////! # Leptos Server Functions
-////!
-////! This package is based on a simple idea: sometimes it’s useful to write functions
-////! that will only run on the server, and call them from the client.
-////!
-////! If you’re creating anything beyond a toy app, you’ll need to do this all the time:
-////! reading from or writing to a database that only runs on the server, running expensive
-////! computations using libraries you don’t want to ship down to the client, accessing
-////! APIs that need to be called from the server rather than the client for CORS reasons
-////! or because you need a secret API key that’s stored on the server and definitely
-////! shouldn’t be shipped down to a user’s browser.
-////!
-////! Traditionally, this is done by separating your server and client code, and by setting
-////! up something like a REST API or GraphQL API to allow your client to fetch and mutate
-////! data on the server. This is fine, but it requires you to write and maintain your code
-////! in multiple separate places (client-side code for fetching, server-side functions to run),
-////! as well as creating a third thing to manage, which is the API contract between the two.
-////!
-////! This package provides two simple primitives that allow you instead to write co-located,
-////! isomorphic server functions. (*Co-located* means you can write them in your app code so
-////! that they are “located alongside” the client code that calls them, rather than separating
-////! the client and server sides. *Isomorphic* means you can call them from the client as if
-////! you were simply calling a function; the function call has the “same shape” on the client
-////! as it does on the server.)
-////!
-////! ### `#[server]`
-////!
-////! The [`#[server]`](https://docs.rs/leptos/latest/leptos/attr.server.html) macro allows you to annotate a function to
-////! indicate that it should only run on the server (i.e., when you have an `ssr` feature in your
-////! crate that is enabled).
-////!
-////! ```rust,ignore
-////! use leptos::prelude::*;
-////! #[server(ReadFromDB)]
-////! async fn read_posts(how_many: usize, query: String) -> Result<Vec<Posts>, ServerFnError> {
-////!   // do some server-only work here to access the database
-////!   let posts = todo!();;
-////!   Ok(posts)
-////! }
-////!
-////! // call the function
-////! spawn_local(async {
-////!   let posts = read_posts(3, "my search".to_string()).await;
-////!   log::debug!("posts = {posts:#?}");
-////! });
-////! ```
-////!
-////! If you call this function from the client, it will serialize the function arguments and `POST`
-////! them to the server as if they were the inputs in `<form method="POST">`.
-////!
-////! Here’s what you need to remember:
-////! - **Server functions must be `async`.** Even if the work being done inside the function body
-////!   can run synchronously on the server, from the client’s perspective it involves an asynchronous
-////!   function call.
-////! - **Server functions must return `Result<T, ServerFnError>`.** Even if the work being done
-////!   inside the function body can’t fail, the processes of serialization/deserialization and the
-////!   network call are fallible.
-////! - **Return types must be [Serializable](leptos_reactive::Serializable).**
-////!   This should be fairly obvious: we have to serialize arguments to send them to the server, and we
-////!   need to deserialize the result to return it to the client.
-////! - **Arguments must be implement [serde::Serialize].** They are serialized as an `application/x-www-form-urlencoded`
-////!   form data using [`serde_qs`](https://docs.rs/serde_qs/latest/serde_qs/) or as `application/cbor`
-////!   using [`cbor`](https://docs.rs/cbor/latest/cbor/). **Note**: You should explicitly include `serde` with the
-////!   `derive` feature enabled in your `Cargo.toml`. You can do this by running `cargo add serde --features=derive`.
-////! - Context comes from the server. [`use_context`](leptos_reactive::use_context) can be used to access specific
-////!   server-related data, as documented in the server integrations. This allows accessing things like HTTP request
-////!   headers as needed. However, server functions *not* have access to reactive state that exists in the client.
-////!
-////! ## Server Function Encodings
-////!
-////! By default, the server function call is a `POST` request that serializes the arguments as URL-encoded form data in the body
-////! of the request. But there are a few other methods supported. Optionally, we can provide another argument to the `#[server]`
-////! macro to specify an alternate encoding:
-////!
-////! ```rust,ignore
-////! #[server(AddTodo, "/api", "Url")]
-////! #[server(AddTodo, "/api", "GetJson")]
-////! #[server(AddTodo, "/api", "Cbor")]
-////! #[server(AddTodo, "/api", "GetCbor")]
-////! ```
-////!
-////! The four options use different combinations of HTTP verbs and encoding methods:
-////!
-////! | Name              | Method | Request     | Response |
-////! | ----------------- | ------ | ----------- | -------- |
-////! | **Url** (default) | POST   | URL encoded | JSON     |
-////! | **GetJson**       | GET    | URL encoded | JSON     |
-////! | **Cbor**          | POST   | CBOR        | CBOR     |
-////! | **GetCbor**       | GET    | URL encoded | CBOR     |
-////!
-////! In other words, you have two choices:
-////!
-////! - `GET` or `POST`? This has implications for things like browser or CDN caching; while `POST` requests should not be cached,
-////! `GET` requests can be.
-////! - Plain text (arguments sent with URL/form encoding, results sent as JSON) or a binary format (CBOR, encoded as a base64
-////! string)?
-////!
-////! ## Why not `PUT` or `DELETE`? Why URL/form encoding, and not JSON?**
-////!
-////! These are reasonable questions. Much of the web is built on REST API patterns that encourage the use of semantic HTTP
-////! methods like `DELETE` to delete an item from a database, and many devs are accustomed to sending data to APIs in the
-////! JSON format.
-////!
-////! The reason we use `POST` or `GET` with URL-encoded data by default is the `<form>` support. For better or for worse,
-////! HTML forms don’t support `PUT` or `DELETE`, and they don’t support sending JSON. This means that if you use anything
-////! but a `GET` or `POST` request with URL-encoded data, it can only work once WASM has loaded.
-////!
-////! The CBOR encoding is supported for historical reasons; an earlier version of server functions used a URL encoding that
-////! didn’t support nested objects like structs or vectors as server function arguments, which CBOR did. But note that the
-////! CBOR forms encounter the same issue as `PUT`, `DELETE`, or JSON: they do not degrade gracefully if the WASM version of
-////! your app is not available.

-/// tracking the progress of each one.
-///
-/// Where an [Action](crate::Action) fires a single call, a `MultiAction` allows you to
-/// keep track of multiple in-flight actions.
-///
-/// If you’re trying to load data by running an `async` function reactively, you probably
-/// want to use a [Resource](leptos_reactive::Resource) instead. If you’re trying to occasionally
-/// run an `async` function in response to something like a user adding a task to a todo list,
-/// you’re in the right place.
-///
-/// ```rust
-/// # use leptos::*;
-/// # let runtime = create_runtime();
-/// async fn send_new_todo_to_api(task: String) -> usize {
-///   // do something...
-///   // return a task id
-///   42
-/// }
-/// let add_todo = create_multi_action(|task: &String| {
-///   // `task` is given as `&String` because its value is available in `input`
-///   send_new_todo_to_api(task.clone())
-/// });
-///
-/// # if false {
-/// add_todo.dispatch("Buy milk".to_string());
-/// add_todo.dispatch("???".to_string());
-/// add_todo.dispatch("Profit!!!".to_string());
-/// # }
-///
-/// # runtime.dispose();
-/// ```
-///
-/// The input to the `async` function should always be a single value,
-/// but it can be of any type. The argument is always passed by reference to the
-/// function, because it is stored in [Submission::input] as well.
-///
-/// ```rust
-/// # use leptos::*;
-/// # let runtime = create_runtime();
-/// // if there's a single argument, just use that
-/// let action1 = create_multi_action(|input: &String| {
-///     let input = input.clone();
-///     async move { todo!() }
-/// });
-///
-/// // if there are no arguments, use the unit type `()`
-/// let action2 = create_multi_action(|input: &()| async { todo!() });
-///
-/// // if there are multiple arguments, use a tuple
-/// let action3 =
-///     create_multi_action(|input: &(usize, String)| async { todo!() });
-/// # runtime.dispose();

+### Leptos Hexagonal Design
+
+This Blog Post / Github Repository is about applying principles of hexagonal design
+    - Isolating Business Logic from Sub Domains
+    - Decoupling design to improve flexibility and testablity
+    - Applying the principles hierachically so that sub domains which talk to external services also implement also implement hexagonal architecture
+
+
+There are specific constraints that guide our design decisions
+
+- Server Functions Can't be Generic
+- Boxed Traits Objects Have overhead, so we only want to use as much generic code as possible avoid Trait Objects
+
+The way this works is we define the functionality of our program in the main domain (i.e the business problem and processes our app is trying to solve / proceduralize). We then create sub domains and external services, although they are represented the same. External services are usually the end nodes of your app's architectural graph. Our main application builds it's service layout using configuration flags.
+
+```rust
+pub fn config() -> MainAppHandlerAlias {
+    cfg_if::cfg_if! {
+                if #[cfg(feature="open_ai_wrapper")] {
+                    fn server_handler_config_1() -> MainAppHandler<
+                        AuthService<PostgresDb, Redis>,
+                        AiMessageGen<PostgresDb,OpenAiWrapper>,
+                        > {
+                        MainAppHandler::new_with_postgres_and_redis_open_ai()
+                    }
+                    server_handler_config_1()
+                } else {
+                    fn server_handler_config_2() -> MainAppHandler<
+                        AuthService<MySql, MemCache>,
+                        OtherAiMessageGen<MySql,HuggingFaceWrapper>,
+                        > {
+                        MainAppHandler::new_with_my_sql_memcache_hugging_face()
+                    }           
+                    server_handler_config_2()
+                }
+            }
+}
+
+```
+
+And we pass in our handler which implements a trait
+
+```rust
+pub trait HandlerServerFn {
+    pub fn server_fn_1_inner(&self);
+}
+impl<S,S2> HandlerServerFn for MainAppHandler<S:SubDomain1Trait,S2:SubDomain2Trait> {
+    pub fn server_fn_1_inner(&self) {
+        // do thing
+    }
+}
+```
+
+in our main fn we produce our applications service graph and pass it to our leptos router.
+
+```rust
+main () {
+   let leptos_options = conf.leptos_options;
+    let routes = generate_route_list(crate::app::App);
+    // our feature flag based config function.
+    let handler = config();
+    let handler_c = handler.clone();
+    // we implement FromRef<ServerState> for LeptosOptions
+    let server_state = ServerState {
+        handler,
+        leptos_options: leptos_options.clone(),
+    };
+    let app = Router::new()
+        .leptos_routes_with_context(
+            &server_state,
+            routes,
+            // We pass in the MainAppHandler struct as context so we can fetch it anywhere context is available on the server.
+            // This includes in middleware we define on server functions (see middleware.rs)
+            move || provide_context(handler_c.clone()),
+            {
+                let leptos_options = leptos_options.clone();
+                move || shell(leptos_options.clone())
+            },
+        )
+        .fallback(leptos_axum::file_and_error_handler::<
+            ServerState<HandlerStructAlias>,
+            _,
+        >(shell))
+        .with_state(server_state);
+}
+```
+
+and then in our server functions 
+
+```rust
+#[server]
+pub async fn server_fn_1() -> Result<(),ServerFnError> {
+    // we type alias every variation of our services we plan on configuring. The alternative is using Box<dyn Trait> which isn't bad - just slower.
+    Ok(expect_context::<MainAppHandlerAlias>().server_fn_1_inner())
+}
+```
+
+And then we can mock and service trait in any combination like so
+
+```rust
+    #[tokio::test]
+    pub async fn test_subdomain_1_with_mocks() -> Result<(), Box<dyn Error>> {
+        let mut mock_external_service_1 = MockExternalServiceTrait1::new();
+        mock_external_service_1
+            .expect_external_service_1_method()
+            .returning(|| {
+                println!("Mock external service 1");
+                Ok(ExternalService1Data)
+            });
+        let mut mock_external_service_2 = MockExternalServiceTrait2::new();
+        mock_external_service_2
+            .expect_external_service_2_method()
+            .returning(|| {
+                println!("Mock external service 2");
+                Ok(ExternalService2Data)
+            });
+        let real_subdomain_1_with_mock_externals = SubDomainStruct1 {
+            external_service_1: mock_external_service_1,
+            external_service_2: mock_external_service_2,
+        };
+        let data = real_subdomain_1_with_mock_externals
+            .sub_domain_1_method()
+            .await?;
+        assert_eq!(data, SubDomain1Data);
+        Ok(())
+    }
+```
