###Instructions to include the package into a project.

In composer.json, require Caching package.

"require": {
        ...
        ...
        "quintype/caching":"1.0.0"
    },

Install or update the composer packages.

$ composer install
or
$ composer update

In the Laravel config/app.php file, add aliases to the packages for convenience.

'aliases' => [
        ...
        ...
        'Caching' => Quintype\Caching\Caching::class
    ],

Include both Caching class in the necessary controllers.

use Caching;

Create a constructor function to initialize the Caching object and to set default caching parameters..

public function __construct(){
  $this->caching = new Caching();
  $this->defaultCacheParams = [
      'publisherId' => <publisher_id>,
      'cdnTTLs' => [
        'max-age' => 3 * 60,
        'stale-while-revalidate' => 5 * 60,
        'stale-if-error' => 4 * 60 * 60,
      ],
      'browserTTLs' => [
        'max-age' => 60,
      ],
  ];
}

Call the function using the created object. Pass all necessary details that will be used for setting cache headers to the function as an associative array.

The argument is an associative array with following keys:

1. publisherId
2. cdnTTLs: Corresponds to Surrogate-Control values.
   1. max-age: This controls how long the page is considered fresh in the Database.
   2. stale-while-revalidate: During this period, the page is served from CDN, but updated in the background.
   3. stale-if-error: During this time, the page is served from CDN in case the backend server crashes for whatever reason.
3. browserTTLs: Corresponds to Cache-Control values
   1. max-age
4. locationId(not required for story page): home or section-id
5. storyGroup(not required for story page): top or stack-id
6. storiesToCache:
   1. Array of all collections under a key for each of them, if driven through collections.
   2. Array of all the stories that have to be cached, if driven through stories.
7. storiesFrom(required for collection driven page): collection
