@@ -90,13 +90,35 @@ Here are some resources for learning more about Leptos:
- [API Documentation](https://docs.rs/leptos/latest/leptos/)
- [Common Bugs](https://github.com/leptos-rs/leptos/tree/main/docs/COMMON_BUGS.md) (and how to fix them!)
## `nightly` Note
Most of the examples assume youre using `nightly` version of Rust and the `nightly` feature of Leptos. To use `nightly` Rust, you can either set your toolchain globally or on per-project basis.
To set `nightly` as a default toolchain for all projects (and add the ability to compile Rust to WebAssembly, if you havent already):
```
rustup toolchain install nightly
rustup default nightly
rustup target add wasm32-unknown-unknown
```
If you'd like to use `nightly` only in your Leptos project however, add [`rust-toolchain.toml`](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file) file with the following content:
```toml
[toolchain]
channel = "nightly"
targets = ["wasm32-unknown-unknown"]
```
The `nightly` feature enables the function call syntax for accessing and setting signals, as opposed to `.get()` and `.set()`. This leads to a consistent mental model in which accessing a reactive value of any kind (a signal, memo, or derived signal) is always represented as a function call. This is only possible with nightly Rust and the `nightly` feature.
## `cargo-leptos`
[`cargo-leptos`](https://github.com/leptos-rs/cargo-leptos) is a build tool that's designed to make it easy to build apps that run on both the client and the server, with seamless integration. The best way to get started with a real Leptos project right now is to use `cargo-leptos` and our starter templates for [Actix](https://github.com/leptos-rs/start) or [Axum](https://github.com/leptos-rs/start-axum).
```bash
cargo install cargo-leptos --locked
cargo leptos new --git https://github.com/leptos-rs/start-axum
cargo install cargo-leptos
cargo leptos new --git https://github.com/leptos-rs/start
cd [your project name]
cargo leptos watch
```

This may be the big one: “production ready” implies a certain orientation to a library: that you can basically use it, without any special knowledge of its internals or ability to contribute. Everyone has this at some level in their stack: for example I (@gbj) dont have the capacity or knowledge to contribute to something like `wasm-bindgen` at this point: I simply rely on it to work.
There are several people in the community using Leptos right now for many websites at work, who have also become significant contributors. There may be missing features that you need, and you may end up building them! But, if you're willing to contribute a few missing pieces along the way, the framework is most definitely usable for production applications, especially given the ecosystem of libraries that have sprung up around it.

This uses *only* server rendering, with no actual islands, but still maintains client-side state across page navigations.
It does this by building on the fact that we now have a statically-typed view tree to do pretty smart updates with
new HTML from the client, with extremely minimal diffing.
The demo itself works, but the feature that supports it is incomplete. A couple people have accidentally
used it and broken their applications in ways they don't understand, so I've renamed the feature to `dont-use-islands-router`.

# Lazy Routes
This example demonstrates how to split the WASM bundle that is sent to the client into multiple binaries, which can be lazy-loaded, either independently or in a way that's integrated into the router.
Without code splitting, the entire application is compiled to a monolithic WASM binary, the size of which grows in proportion to the complexity of the application. This means that the time to interactive (TTI) for any page is proportional to the size of the entire application, not only that page.
Code splitting allows you to lazy-load some functions, by splitting off the WASM binary code for certain functions into separate files, which can be downloaded as needed. This minimizes initial TTI for any page, and then amortizes the cost of loading the binary over the lifetime of the application session.
In many cases, this can be done with minimal or no cost.
Lazy loading can be used in two ways, each of which is shown in the example.
## `#[lazy]` macro
`#[lazy]` is an attribute macro that can be used to annotate an `async fn` in order to split its code out into a separate file that will be loaded on demand, when compiled with `cargo leptos --split`.
This has some limitations (for example, it must return concrete types) but can be used for most functions.
## `LazyRoute`
`LazyRoute` is a specialized application of `#[lazy]` that allows you to define an entire route/page of your application as being lazy-loaded.
Creating a lazy route requires you to split the route into two parts:
1. `data()`: A synchronous method that should be used to start loading any async data used by the page, for example by creating a `Resource`
2. `view()`: An async (because lazy-loaded) method that renders the view.
The purpose of splitting these into two parts is to avoid a “waterfall,” in which the browser first waits for a lazy-loaded WASM chunk that defines the page, _then_ makes a second request to the server to load the relevant data. Instead, a `LazyRoute` will begin loading resources created in the `data` method while lazy-loading the component body in the `view`, then render the route.
This means that in many cases, the data loading “hides” the cost of the lazy-loading; i.e., the page needs to wait for the data to load, so the fact that it is waiting concurrently for the lazy-loaded view means that the lazy loading does not cost anything additional in terms of page load time.

# Hot Patching with `dx`
This is an experimental example exploring how to combine Leptos with the binary hot-patching provided by Dioxus's `subsecond` library and `dx` cli.
### Serving Your App
This requires installing the Dioxus CLI version 0.7.0. At the time I'm writing this README, that does not yet have a stable release. Once `dioxus-cli` 0.7.0 has been released, you should use the latest stable release. Until then, I'd suggest installing from git:
```sh
cargo install dioxus-cli --git https://github.com/DioxusLabs/dioxus
```
Then you can run the example with `dx serve --hot-patch --platform web`.
### Hot Patching
Changes to the your application should be reflected in your app without a full rebuild and reload.
### Limitatations
Currently we only support hot-patching for reactive view functions. You probably want to use `AnyView` (via `.into_any()`) on any views that will be hot-patched, so they can be rebuilt correctly despite their types changing when the structure of the view tree changes.
If you are using `leptos_router` this actually works quite well, as every routes view is erased to `AnyView` and the router itself is a reactive view function: in other words, changes inside any route should be hot-patched in any case.
Note that any hot-patch will cause all render effects to run again. This means that some client-side state (like the values of signals) will be wiped out.
### Build Tooling
The preference of the Dioxus team is that all hot-patching work that uses their `subsecond` also use `dioxus-cli`. As this demo shows, it's completely possible to use `dioxus-cli` to build and run a Leptos project. We do not plan to build `subsecond` into our own build tooling at this time.
**This is an experiment/POC. It is being published because members of the community have found it useful and have asked for the support to be merged in its current state. Further development and bugfixes are a relatively low priority at this time.**
