README

This package provides a polyfill for the Cache::flexible() method, which was introduced in Laravel 11. It brings the stale while revalidating cache pattern to Laravel 10.

When using Cache::remember, some users may experience slow response times if the cached value has expired. The flexible method allows stale data to be served while the cached value is recalculated in the background after the response is sent, preventing slow response times for your users.

Installation

You can install the package via composer:

composer require spatie/laravel-flexible-cache-polyfill

Usage

Using the Cache::flexible() facade:

$value = Cache::flexible('users', [5, 10], function () {
    return DB::table('users')->get();
});

The first value (5) is the number of seconds the cache is considered "fresh". The second value (10) defines how long it can be served as stale data before recalculation is necessary.

• 0-5 seconds: Returns cached value immediately
• 5-10 seconds: Returns stale value, refreshes in background after response is sent
• After 10 seconds: Cache expired, recalculates immediately

Support for all stores is available:

$value = Cache::store('redis-2')->flexible(...);
