# svelte-guard-history-router
svelte guarded history router
# Features
* Named params `article/:id`
* Guards to act when entering or leaving a route
* Automatic route ranking (more specific routes have higher priority)
* Routes and keys acting as stores
* Nested Routes with relative paths for route composition (Shared Leave Routes)
* Route values
* Object <=> parameter mapping
* Create links from objects
* Standart `Home` elements
## Shared Leave Routes
```html
```
# usage
