What is the difference between a JsonResource & ResourceCollection? in Laravel v6 or v7

Can someone explain the difference between a ResourceCollection and JsonResource?

In Laravel 6 docs you can generate 2 different types of resources… ResourceCollection and JsonResource. https://laravel.com/docs/6.x/eloquent-resources#resource-responses

<?php

namespace AppHttpResources;

use IlluminateHttpResourcesJsonResourceCollection;

class ShopCollection extends ResourceCollection
{
    /**
     * Transform the resource collection into an array.
     *
     * @param  IlluminateHttpRequest  $request
     * @return array
     */
    public function toArray($request)
    {
        return parent::toArray($request);
    }
}

vs …

<?php

namespace AppHttpResources;

use IlluminateHttpResourcesJsonJsonResource;

class Shop extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  IlluminateHttpRequest  $request
     * @return array
     */
    public function toArray($request)
    {
        return parent::toArray($request);
    }
}

Answer

ResourceCollection use for a list of items but JsonResource use for a single item.

I copy piece of code that used it in my project: in my project I had list of articles, so I have to showed list of articles, so I used ResourceCollection that return a array of articles :

<?php
namespace AppHttpResourcesApiCollection;
use IlluminateHttpResourcesJsonResourceCollection;

class AlbumCollection extends ResourceCollection
{
    /**
     * Transform the resource collection into an array.
     *
     * @param  IlluminateHttpRequest  $request
     * @return array
     */
    public function toArray($request)
    {
        return $this->collection->map(function ($item) {
            return [
                'id' => $item->id,
                'name' => $item->name,
                'description' => $item->description
            ];
        });
    }

    public function with($request)
    {
        return [
            'status' => true
        ];
    }
}

this code return for I a list of articles. then when user click on a article, I must show to user a single article, so I must return a single article and I used following code:

<?php
namespace AppHttpResourcesApiResources;
use IlluminateHttpResourcesJsonJsonResource;

class NewsResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  IlluminateHttpRequest  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'title' => $this->title,
            'body' => $this->body,
            'cover' => $this->cover,
            'view_count' => $this->view_count,
            'comment_count' => $this->comment_count,
            'like_count' => $this->like_count,
            'created_at' => $this->created_at,
            'updated_at' => $this->updated_at,
            'comments' => $this->comments
        ];
    }

    public function with($request)
    {
        return [
            'status' => true
        ];
    }
}
