[tsndp]

How to define and how will it render. please include in Readme.

This is now unchanged. Same as the previous package

For example, route definition

// routes/web.php
Route::resource('photo', PhotoController::class);

And the explicit indication of breadcrumbs:

// Any service provider

// Photos
Breadcrumbs::for('photo.index', fn (Trail $trail) =>
    $trail->parent('home')
        ->push('Photos', route('photo.index'))
);

// Photos > Upload Photo
Breadcrumbs::for('photo.create', fn (Trail $trail) =>
    $trail->parent('photo.index')
        ->push('Upload Photo', route('photo.create'))
);

// Photos > [Photo Name]
Breadcrumbs::for('photo.show', fn (Trail $trail, Photo $photo) =>
    $trail->parent('photo.index')
        ->push($photo->title, route('photo.show', $photo->id))
);

// Photos > [Photo Name] > Edit Photo
Breadcrumbs::for('photo.edit', fn (Trail $trail, Photo $photo) =>
    $trail->parent('photo.show', $photo)
        ->push('Edit Photo', route('photo.edit', $photo->id))
);

this we can not do in routes file? we need to maintain another location

Route files are cached, so after running the php artisan route:cache command, they will not be executed. Dave James Miller package just does use PHP function require in the service provider.

You can easily repeat this:

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class BreadcrumbsServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application events.
     *
     * @return void
     */
    public function boot()
    {
        require base_path('routes/breadcrumbs.php');
    }
}

Then it will be your special file in the route directory:

// routes/breadcrumbs.php

// Photos
Breadcrumbs::for('photo.index', fn (Trail $trail) =>
    $trail->parent('home')
        ->push('Photos', route('photo.index'))
);
