## Installation

```
npm install easy-page-router
```

## Usage

```js
import { Router, RouterProvider } from "easy-page-router";

function App() {
    return (
        <RouterProvider>
            <Layout>
                <Router
                    renderPage={({ path }) => {
                        if (path.length === 0) {
                            // "/"
                            return <HomePage />;
                        } else if (path[0] === "song" && path[1]) {
                            // "/song/:id"
                            return <SongPage songId={path[1]} />;
                        }
                        return <NotFoundPage />;
                    }}
                />
            </Layout>
        </RouterProvider>
    );
}
```

## Page Transition Animations

The variable state offers the values "active" | "back" | "forward" so it is
possible to set animations via CSS (react) or Animated (react-native) on change.
All pages remain rendered.

```js
import { Router } from "easy-page-router";

function PageRouter() {
    return <Router
        renderAnimation={Animation}
        renderPage={({ path }) => {
            if (path.length === 0) {
                return <HomePage />;
            } else if (path[0] === "song" && path[1]) {
                return <SongPage songId={path[1]} />;
            }
            return <NotFoundPage />;
        }}
    />;
}

function Animation({ page, state }: RenderAnimationProps) {
    const [newClass, setNewClass] = useState("new");

    useEffect(() => {
        if (state !== "active") setNewClass("");
    }, [state]);

    return <div className={`page-animation ${state} ${newClass}`}>{page}</div>;
}
```

## Whole API

```js
import { Router, RouterProvider, useRouter } from "easy-page-router";
import { Link, useTitle } from "easy-page-router/react";
import { Link } from "easy-page-router/react-native";

type UseRouter = {
    path: string[];
    searchParams: Record<string, string>;
    state: "active" | "back" | "forward";
    href: string;
    to: string;
    pageKey: string;

    push: (to: string) => void;
    back: () => void;
    forward: () => void;
}
```

When a `Link` component is active in React, it receives the `active` className
for styling, while in React Native, the `styleActive` prop is applied instead.
