- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.

Informations about the package laravel-cache-flusher
Laravel Cache Flusher
A lightweight package to invalidate cache entries automatically when the cached data changed.
Why
The current cache management system provided by laravel is great and satisfiable. To handle the cache invalidation when data update, you can do that manually or you may group your cache entries under tags and do invalidation by tags (like Redis). Even with tagging, it becomes difficult to handle all of tags spread all over the code base when the project get larger.
This package provides an easy way to track the changes over models and do an automatic invalidation in your behave. Just define the relation between your cache and models and your life will become easier.
Installation
Install using composer:
After installation run the following code to publish the config:
Basic Usage
It is very simple to use this package, you need only to configure all the required variables and taste the sweet of this package
1) enabled (default : false)
To enable/disable this package in your project ,
you can control its value using the entry CACHE_FLUSHER_ENABLED
in your .env file.
2) driver (default : your default cache driver)
It will be used to specify the cache driver the package will work with,
it is preferable to use the cache driver similar to the one you used in your project
(to make sure that all the operations done on the same cache driver).
you can control its value using the entry CACHE_FLUSHER_DRIVER
in your .env file.
3) cool-down (default : null)
Some time you have a bulk of operation done over the model/s within short period of time.
To avoid the high rate cache invalidation for a specific period (cool down period) you can specify a value (in seconds) for this config
entry.
you can control its value using the entry CACHE_FLUSHER_COOL_DOWN
in your .env file.
4) mapping (default : [])
The most important part in our package. Here you can specify the cache keys along with the models that cause their invalidation.
In the following example,
the store_info,store_info.categories will be invalidated when Category model changed (create|update|delete)
the store_info,store_info.products will be invalidated when Product model changed (create|update|delete)
The keys can also be a regex expression, and when any change over the models occurred, all the matched keys will be invalidated
In the following example, all they cache entry started with
store. or mobile. will be invalidated
if Product or Category changed (create|update|delete)
All they cache entry end with
.products or .categories. will be invalidated
if Product, Category, or Attribute changed (create|update|delete)
Advanced Usage
Some time you may want to provide some condition when invalidating the cache keys. One examples: you have a multi tenant project and you want to invalidate the cache entries of a specific company.
The package can help you with that by providing a binding resolving within the defined mapping config param.
One last thing, you have to provide a binding function (in your service provider) to extract the related values
from the model that trigger the invalidation operation.
Example:
The binding function accept two params: $bindingKey which represent the matched binding key.
$model is the model who triggered the invalidation operation. The defined function will be called
for each matched param in the defined cache entry patterns (mapping in config file)
Now, according to the following mapping configuration :
When the User model changed, all the entries that start with
companies.1.stores and companies.1.mobiles.2 will be invalidated.
NOTE: {company_id} is fixed to 1 in the binding function, {user_id} is fixed to 2 in the binding function.
