What is Laravel route model binding?

 Route model binding lets Laravel resolve a route parameter into an Eloquent model.

Example:
Route::get('/products/{product}', [ProductController::class, 'show']);

Controller:
public function show(Product $product)
{
return $product;
}

Instead of manually doing Product::findOrFail($id), Laravel can resolve the model.

Scenario:
For /products/25, Laravel can retrieve Product 25 and automatically produce a not-found response when appropriate.

A developer should understand custom keys as well, such as binding by slug rather than numeric ID. This is useful for SEO-friendly URLs.
