This package contains a helper function (and a Facade should you prefer that) called blink that can cache values. The cache only spans the length of a single request.
blink()->put('key', 'value');
blink()->get('key'); // Returns 'value'
blink()->get('prefix*'); // Returns an array of values whose keys start with 'prefix'
// once will only execute the given callable if the given key didn't exist yet
// once will only execute the given callable if the given key didn't exist yet
$expensiveFunction = function() {
return rand();
});
blink()->once('random', $expensiveFunction); // returns random number
blink()->once('random', $expensiveFunction); // returns the same number
blink()->has('key'); // Returns true
blink()->has('prefix*'); // Returns true if the blink contains contains a key that starts with 'prefix'
// Specify a default value for when the specified key does not exist
blink()->get('non existing key', 'default') // Returns 'default'
blink()->put('anotherKey', 'anotherValue');
// Put multiple items in one go
blink()->put(['ringo' => 'drums', 'paul' => 'bass']);
blink()->all(); // Returns an array with all items
blink()->forget('key'); // Removes the item
blink()->forget('prefix*'); // Forget all items of which the key starts with 'prefix'
blink()->flush(); // Empty the entire blink
blink()->flushStartingWith('somekey'); // Remove all items whose keys start with "somekey"
blink()->increment('number'); // blink()->get('key') will return 1
blink()->increment('number'); // blink()->get('key') will return 2
blink()->increment('number', 3); // blink()->get('key') will return 5
// Blink implements ArrayAccess
blink()['key'] = 'value';
blink()['key']; // Returns 'value'
isset(blink()['key']); // Return true
unset(blink()['key']); // Equivalent to removing the value
// Blink implements Countable
count(blink()); // Returns 0
blink()->put('key', 'value');
count(blink()); // Returns 1You can install the package via composer:
composer require spatie/laravel-blinkTo enable the package, register the serviceprovider, and optionally register the facade:
// config/app.php
'providers' => [
// ...
Spatie\LaravelBlink\BlinkServiceProvider::class,
],
'aliases' => [
...
'Blink' => Spatie\LaravelBlink\BlinkFacade::class,
],A Blink instance can just be newed up.
$blink = new \Spatie\Blink\Blink()You can call the following methods on it:
/**
* Put a value in the blink cache.
*
* @param string|array $name
* @param string|int|null $value
*
* @return $this
*/
public function put($name, $value = null)/**
* Get a value from the blink cache.
*
* This function has support for the '*' wildcard.
*
* @param string $name
*
* @return null|string
*/
public function get(string $name)/*
* Determine if the blink cache has a value for the given name.
*
* This function has support for the '*' wildcard.
*/
public function has(string $name) : bool/**
* Only if the given key is not present in the blink cache the callable will be executed.
*
* The result of the callable will be stored in the given key and returned.
*
* @param $key
* @param callable $callable
*
* @return mixed
*/You can use this to avoid using static variables to cache stuff.
This piece of code
function foo()
{
static $result = null;
if (is_null($result) {
$result = ...// do some expensive stuff here
}
return $result;
}can be rewritten to
function foo()
{
return blink()->once('fooCache', function() {
return ... // do some expensive stuff here
});
}/*
* Get all values in the blink cache.
*/
public function all() : array/**
* Forget a value from the blink cache.
*
* This function has support for the '*' wildcard.
*
* @param string $key
*
* @return $this
*/
public function forget(string $key)/**
* Flush all values from the blink cache.
*
* @return $this
*/
public function flush()/**
* Get and forget a value from the blink cache.
*
* This function has support for the '*' wildcard.
*
* @param string $name
*
* @return null|string
*/
public function pull(string $name)/**
* Increment a value from the blink cache.
*
* @param string $name
* @param int $by
*
* @return int|null|string
*/
public function increment(string $name, int $by = 1)/**
* Decrement a value from the blink cache.
*
* @param string $name
* @param int $by
*
* @return int|null|string
*/
public function decrement(string $name, int $by = 1)Please see CHANGELOG for more information what has changed recently.
