Symfony service memoization bundle
==================================

[](#symfony-service-memoization-bundle)

This bundle provides memoization for your services - every time you call the same method with the same arguments a cached response will be returned instead of executing the method.

Installation
------------

[](#installation)

Requires php 8.1+.

`composer require rikudou/memoize-bundle`

Afterwards add this to your `composer.json` autoload PSR-4 section: `"App\\Memoized\\": "memoized/"`

Example on fresh Symfony project:

```
{
  "autoload": {
    "psr-4": {
      "App\\": "src/",
      "App\\Memoized\\": "memoized/" // add this line
    }
  }
}
```

Usage
-----

[](#usage)

You can simply use the provided attributes.

- `#[Memoizable]` - Every class that has memoized methods must have this attribute.
- `#[Memoize]` - An attribute that can be used on classes or methods to mark given class/method as memoized. Has an optional parameter with number of seconds for cache validity. Default to `-1` which means until end of the process (meaning end of request in standard php-fpm and apache2 configurations)
- `#[NoMemoize]` - An attribute that allows you to mark a method as non memoized in case you made the whole class memoized.

Every memoized class needs to implement at least one interface that you use to typehint the given service. A proxy class is created for each service with `#[Memoizable]` attribute. This proxy class decorates your service so that every time you ask for your service the proxy gets injected instead.

For non-memoized methods the proxy class simply passes the arguments through to your service while for memoized methods it also creates a cache key based on the parameters and looks for the result into the cache.

> The proxy classes are generated in a compiler pass, meaning the proxy creation doesn't add overhead once container has been dumped.
