    build: ({ instance }) => {
        instance.nodeIndex.forEach(node => {
            const matches = node.name?.match(/^(\d+)\.(.+)/)
            if (matches) {
                const [, index, name] = matches
                node.name = name
                node.meta.index = index
            }
        })
    }
})

```

--------------------------------

### Plugin Structure and Example

Source: https://routify.dev/docs/guide/installation/manual-installation

    name: 'string',
    before: 'string', // optional plugin name this plugin should run before
    after: 'string', // optional plugin name this plugin should run after
    build: ({ instance }) => void
})
```

```javascript
// this plugin sorts routes by the index prefixed to their names
// eg. 1.guide.svelte, 2.api.svelte
export default options => ({
    name: 'indexByName',
    
    // we want to run our plugin before we write our routes to disk
    before: 'exporter', 
    
    
    build: ({ instance }) => {

        // iterate over all nodes
        instance.nodeIndex.forEach(node => {

            // if our node name matches 123.foo
            // set the name to foo and the meta index to 123
            const matches = node.name?.match(/^(d+).(.+)/)
            if (matches) {
                const [, index, name] = matches
                node.name = name
                node.meta.index = index

```

--------------------------------

### Routify Theme Presets Configuration

Source: https://routify.dev/docs/api/metadata

Define theme presets in Routify's configuration to organize routes by contexts such as language, season, or UI mode. This setup allows for dynamic routing based on these contexts, with fallback mechanisms for broader compatibility.

```javascript
{
    themes: {
        presets: {
            en: ['en'],
            en_gb: ['en-gb', 'en'], // fallback to US English
            de: ['de', 'en'],            
            en_xmas: [['en', 'xmas'], 'en'], // compound theme
            // Prefer US English Xmas over localized English without Xmas
            en_gb_xmas: [['en-gb', 'xmas'], ['en', 'xmas'], 'en-gb', 'en'],
            // Always prefer German

### Programmatic Navigation

Source: https://routify.dev/docs/guide/concepts/preloading

Handles programmatic navigation to a specified path. Supports various options including `mode` (push/replace), `silent` error suppression, and `strict` path matching.

```javascript
import { $goto } from '@roxi/routify';

$goto('/dashboard', { replace: true });
// Navigates to /dashboard, replacing the current history entry
```

--------------------------------

### Create URL with Parameters

Source: https://routify.dev/docs/guide/concepts/preloading

Generates URLs from internal paths and provided parameters. Unused parameters are appended as query strings. Supports '$leaf' for the current node's URL.

```javascript
import { $url } from '@roxi/routify';

const url = $url('/blog/[slug]/comments', { slug: 'my-post', commentId: 123 });
// url will be '/blog/my-post/comments?commentId=123'
```

--------------------------------

### Example: Sort Routes by Index Prefix Plugin

Source: https://routify.dev/docs/guide/advanced/how-it-works

This example plugin sorts routes based on an index prefix in their names (e.g., '1.guide.svelte'). It modifies node names and adds an 'index' meta property during the build process.

```javascript
export default options => ({
    name: 'indexByName',
    before: 'exporter',
    build: ({ instance }) => {
        instance.nodeIndex.forEach(node => {
            const matches = node.name?.match(/^(d+).(.+)/);
            if (matches) {
                const [, index, name] = matches;
                node.name = name;
                node.meta.index = index;
            }
        });
    }
})
```

--------------------------------

### Example Routify Plugin: Sort routes by index

Source: https://routify.dev/docs/guide/introduction/navigation

An example plugin that sorts Routify nodes based on a numerical index prefixed to their names (e.g., '1.guide.svelte'). It modifies the node names and metadata during the build process. It specifies to run 'before' the 'exporter' plugin.

```javascript
export default options => ({
    name: 'indexByName',
    before: 'exporter',
    build: ({ instance }) => {
        instance.nodeIndex.forEach(node => {
            const matches = node.name?.match(/^(d+).(.+)/);
            if (matches) {
                const [, index, name] = matches;
                node.name = name;
                node.meta.index = parseInt(index, 10);
            }
        });
    }
})
```

### Routify Migration Guide

Source: https://routify.dev/docs/guide/advanced/multiple-routers

Key changes and considerations when migrating from older versions of Routify to Routify 3, which is a complete rewrite.

```APIDOC
## Migration Guide

Routify 3 shares the name with Routify 1 and 2, but it’s a completely new routing framework built from scratch. As a result, there’s no direct upgrade path, but here are the most significant changes:

*   **Default routes path:** `src/pages` to `src/routes`
*   **Deprecated helpers** :
    *   `$metatags`
    *   `$focus`
    *   `$ready` (Routify 3 currently only supports Svelte’s native SSR)
    *   `$prefetch` → `data-routify-prefetch-data`
    *   `$route` → `$activeRoute`
    *   `$isChangingPage` → `$pendingRoute`
    *   `$leftover` → `spread parameters`
    *   `$afterPageLoad` → `$afterRouteRendered`
    *   `$page` → `$route.leaf`
    *   `$layout` → `$node`
    *   `$getConcestor` → `$getMRCA`
*   The first `.` in relative paths (`$url` and `$goto`) now refers to the component itself, not the parent module.
*   `<slot scoped={data} />` → `<slot props={data}>`. Props can be accessed at `export let context.props`.
*   `<!-- routify:option -->` → `<!-- routify:meta -->`
*   `_fallback.svelte` deprecated → use `[...404].svelte` or similar (spread param path).
*   For configuring `main.js`, `App.svelte` and `index.html`, refer to the starter templates: (`npm init routify@latest`).
```

--------------------------------

### Routify Plugin Example: Index by Name

Source: https://routify.dev/docs/guide/concepts/inlined-pages

An example plugin that sorts routes based on an index prefix in their names (e.g., '1.guide.svelte'). It modifies node names and meta indices during the build process.

```javascript
// this plugin sorts routes by the index prefixed to their names
// eg. 1.guide.svelte, 2.api.svelte
export default options => ({
    name: 'indexByName',
    
    // we want to run our plugin before we write our routes to disk
    before: 'exporter',
    
    
    build: ({ instance }) => {

        // iterate over all nodes
        instance.nodeIndex.forEach(node => {

            // if our node name matches 123.foo
            // set the name to foo and the meta index to 123
            const matches = node.name?.match(/^(\d+).(.+)/)
            if (matches) {
                const [, index, name] = matches
                node.name = name
                node.meta.index = parseInt(index, 10) // Ensure index is a number
            }
        })
    }
})
```

--------------------------------

### Preload Data with 'props' Field

Source: https://routify.dev/docs/api/metadata

Demonstrates preloading data for a component using the 'props' field within a module script. This runs before the component is loaded, enabling data fetching in advance.

```svelte
<script context="module">
  export async function preLoad() {
    return {
      // props: { data: await fetchData() }
    }
  }
</script>

<script>
  export let data;
</script>

<p>Data: {data}</p>
```
