3cdcc85c87 feat(config): implement common traits for Env (#1324)
In order to facilitate its usage in other structs, which might derive
various traits, such as `serde::Serialize` or `PartialEq`, implement
them for the `leptos_config::Env` enum.

c755dae6ee feat(leptos-config): kebab-case via serde's rename_all (#1308)
Currently, `leptos::LeptosOptions` are deserialized (and serialized)
to `snake_case`, since, by default, `serde` uses the name of the field
as-is. The options given via `.toml` files are given using `kebab-case`.
This behaviour leads to problems if you wish to use
`leptos::LeptosOptions` as the type of a field in your own config,
which uses the `kebab-case` syntax, as it will not provide any values
to that field.

These changes switch out the previous mechanism of manually replacing
the `-` character to the `_` character in order for serialization to
work. In its place, it uses `serde`'s `#[serde(rename_all = ...)]`
macro to handle the naming convention.

In case other naming conventions are used, a workaround would be to
define a user-owned mirror struct of `leptos::LeptosOptions`, which
would contain the required fields, deserialize it as desired and'
convert it to the latter via, for example, the `From<T>` trait.

Closes: #1295

4cc65f837f chore: add mdbook in flake (#1299)
* nix-flake: use follows for `rust-overlay` (..)

This removes the extra nixpkgs dependency by re-using the nixpkgs
already defined.

https://nixos.wiki/wiki/Flakes
https://web.archive.org/web/20230621091703/https://nixos.wiki/wiki/Flakes

> # The `follows` keyword in inputs is used for inheritance.
> # Here, `inputs.nixpkgs` of sops-nix is kept consistent with the `inputs.nixpkgs` of
> # the current flake, to avoid problems caused by different versions of nixpkgs.

* nix-flake: use nix overlays for rustc/cargo (..)

This allows the same nightly rust version to be used across the
flake (vs. strictly in the `devShell`).

* nix-flake: add `mdbook` to the development shell (..)

bumped `nixpkgs` to the latest unstable to pull in mdbook version `0.4.30`.

* nix-flake: expose all rust tools in dev environment (..)

The `oxalica / rust-overlay` docs expose all tools in the development
environment, so we should do the same:

https://github.com/oxalica/rust-overlay#use-in-devshell-for-nix-develop

```rust
use leptos::*;
// So far, we've only been working with local state in components
// We've only seen how to communicate between parent and child components
// But there are also more general ways to manage global state
//
// The three best approaches to global state are
// 1. Using the router to drive global state via the URL
// 2. Passing signals through context
// 3. Creating a global state struct and creating lenses into it with `create_slice`
//
// Option #1: URL as Global State
// The next few sections of the tutorial will be about the router.
// So for now, we'll just look at options #2 and #3.
// Option #2: Pass Signals through Context
//
// In virtual DOM libraries like React, using the Context API to manage global
// state is a bad idea: because the entire app exists in a tree, changing
// some value provided high up in the tree can cause the whole app to render.
//
// In fine-grained reactive libraries like Leptos, this is simply not the case.
// You can create a signal in the root of your app and pass it down to other
// components using provide_context(). Changing it will only cause rerendering
// in the specific places it is actually used, not the whole app.
#[component]
fn Option2(cx: Scope) -> impl IntoView {
// here we create a signal in the root that can be consumed
// anywhere in the app.

// we'll pass the setter to specific components,
// but provide the count itself to the whole app via context
provide_context(cx, count);
view! { cx,
<h1>"Option 2: Passing Signals"</h1>
// SetterButton is allowed to modify the count
<SetterButton set_count/>
// These consumers can only read from it
// But we could give them write access by passing `set_count` if we wanted
<div style="display: flex">
<FancyMath/>
<ListItems/>

//
// You can use this approach to build a single global data structure
// that holds the state for your whole app, and then access it by

// so that changing one part of the state doesn't cause parts of your

The `SimpleCounter` function itself runs once. The `value` signal is created once. The framework hands off the `increment` function to the browser as an event listener.

This can get a little messy: deriving a signal that wraps an `Option<_>` or `Result<_>` can involve a couple steps. But its worth doing this for two reasons:
1. Its correct, i.e., it forces you to consider the cases, “What if the user doesnt pass a value for this query field? What if they pass an invalid value?”
2. Its performant. Specifically, when you navigate between different paths that match the same `<Route/>` with only params or the query changing, you can get fine-grained updates to different parts of your app without rerendering. For example, navigating between different contacts in our contact-list example does a targeted update to the name field (and eventually contact info) without needing to replacing or rerender the wrapping `<Contact/>`. This is what fine-grained reactivity is for.

# The `<Form/>` Component
Links and forms sometimes seem completely unrelated. But in fact, they work in very similar ways.
Links and forms sometimes seem completely unrelated. But, in fact, they work in very similar ways.
In plain HTML, there are three ways to navigate to another page:
1. An `<a>` element that links to another page. Navigates to the URL in its `href` attribute with the `GET` HTTP method.

These are relatively simple examples accessing basic data from the server. But you can use extractors to access things like headers, cookies, database connection pools, and more, using the exact same `extract()` pattern.
> Note: For now, the Axum `extract` function only supports extractors for which the state is `()`, i.e., you can't yet use it to extract `State(_)`. You can access `State(_)` by using a custom handler that extracts the state and then provides it via context. [Click here for an example](https://github.com/leptos-rs/leptos/blob/a5f73b441c079f9138102b3a7d8d4828f045448c/examples/session_auth_axum/src/main.rs#L91-L92).
## A Note about Data-Loading Patterns
Because Actix and (especially) Axum are built on the idea of a single round-trip HTTP request and response, you typically run extractors near the “top” of your application (i.e., before you start rendering) and use the extracted data to determine how that should be rendered. Before you render a `<button>`, you load all the data your app could need. And any given route handler needs to know all the data that will need to be extracted by that route.

# Responses and Redirects
Extractors provide an easy way to access request data inside server functions. Leptos also provides a way to modify the HTTP response, using the `ResponseOptions` type (see docs for [Actix](https://docs.rs/leptos_actix/latest/leptos_actix/struct.ResponseOptions.html) or [Axum](https://docs.rs/leptos_axum/latest/leptos_axum/struct.ResponseOptions.html)) types and the `redirect` helper function (see docs for [Actix](https://docs.rs/leptos_actix/latest/leptos_actix/fn.redirect.html) or [Axum](https://docs.rs/leptos_axum/latest/leptos_axum/fn.redirect.html)).
## `ResponseOptions`
`ResponseOptions` is provided via context during the initial server rendering response and during any subsequent server function call. It allows you to easily set the status code for the HTTP response, or to add headers to the HTTP response, e.g., to set cookies.
```rust
#[server(TeaAndCookies)]
pub async fn tea_and_cookies(cx: Scope) -> Result<(), ServerFnError> {
use actix_web::{cookie::Cookie, http::header, http::header::HeaderValue};
use leptos_actix::ResponseOptions;
// pull ResponseOptions from context
let response = expect_context::<ResponseOptions>(cx);
// set the HTTP status code
response.set_status(StatusCode::IM_A_TEAPOT);
// set a cookie in the HTTP response
let mut cookie = Cookie::build("biscuits", "yes").finish();
if let Ok(cookie) = HeaderValue::from_str(&cookie.to_string()) {
res.insert_header(header::SET_COOKIE, cookie);
}
}
```
## `redirect`
One common modification to an HTTP response is to redirect to another page. The Actix and Axum integrations provide a `redirect` function to make this easy to do. `redirect` simply sets an HTTP status code of `302 Found` and sets the `Location` header.
Heres a simplified example from our [`session_auth_axum` example](https://github.com/leptos-rs/leptos/blob/a5f73b441c079f9138102b3a7d8d4828f045448c/examples/session_auth_axum/src/auth.rs#L154-L181).
```rust
#[server(Login, "/api")]
pub async fn login(
cx: Scope,
username: String,
password: String,
remember: Option<String>,
) -> Result<(), ServerFnError> {
// pull the DB pool and auth provider from context
let pool = pool(cx)?;
let auth = auth(cx)?;
// check whether the user exists
let user: User = User::get_from_username(username, &pool)
.await
.ok_or_else(|| {
ServerFnError::ServerError("User does not exist.".into())
})?;
// check whether the user has provided the correct password
match verify(password, &user.password)? {
// if the password is correct...
true => {
// log the user in
auth.login_user(user.id);
auth.remember_user(remember.is_some());
// and redirect to the home page
leptos_axum::redirect(cx, "/");
Ok(())
}
// if not, return an error
false => Err(ServerFnError::ServerError(
"Password does not match.".to_string(),
)),
}
}
```
This server function can then be used from your application. This `redirect` works well with the progressively-enhanced `<ActionForm/>` component: without JS/WASM, the server response will redirect because of the status code and header. With JS/WASM, the `<ActionForm/>` will detect the redirect in the server function response, and use client-side navigation to redirect to the new page.

Its pretty rare that you do this intentionally, but it could happen from somehow running different logic on the server and in the browser. If youre seeing warnings like this and you dont think its your fault, its much more likely that its a bug with `<Suspense/>` or something.

### Mutating the DOM during rendering
This is a slightly more common way to create a client/server mismatch: updating a signal _during rendering_ in a way that mutates the view.
```rust
#[component]
pub fn App(cx: Scope) -> impl IntoView {
let (loaded, set_loaded) = create_signal(cx, false);
// create_effect only runs on the client
create_effect(cx, move |_| {
// do something like reading from localStorage
set_loaded(true);
});
move || {
if loaded() {
view! { cx, <p>"Hello, world!"</p> }.into_any()
} else {
view! { cx, <div class="loading">"Loading..."</div> }.into_any()
}
}
}
```
This one gives us the scary panic
```
panicked at 'assertion failed: `(left == right)`
left: `"DIV"`,
right: `"P"`: SSR and CSR elements have the same hydration key but different node kinds.
```
And a handy link to this page!
The problem here is that `create_effect` runs **immediately** and **synchronously**, but only in the browser. As a result, on the server, `loaded` is false, and a `<div>` is rendered. But on the browser, by the time the view is being rendered, `loaded` has already been set to `true`, and the browser is expecting to find a `<p>`.
#### Solution
You can simply tell the effect to wait a tick before updating the signal, by using something like `request_animation_frame`, which will set a short timeout and then update the signal before the next frame.
```rust
create_effect(cx, move |_| {
// do something like reading from localStorage
request_animation_frame(move || set_loaded(true));
});
```
This allows the browser to hydrate with the correct, matching state (`loaded` is `false` when it reaches the view), then immediately update it to `true` once hydration is complete.
### Not all client code can run on the server
Imagine you happily import a dependency like `gloo-net` that youve been used to using to make requests in the browser, and use it in a `create_resource` in a server-rendered app.

You'll also want to change the path of the `<StyleSheet / >` component in the root component to point towards the CSS file in the root. This tells leptos that the WASM/JS files generated by wasm-pack are available at `./pkg` and that the CSS files are no longer processed by cargo-leptos. Building to alternative folders is not supported at this time. You'll also want to edit the call to `get_configuration()` to pass in `Some(Cargo.toml)`, so that Leptos will read the settings instead of cargo-leptos.
