This page may look long and boring to read at first, but bear with me!!!
I bet if you read through it you won't get disappointed at the end.So let's Go... :horse_racing:
Installation: :arrow_down:
:electric_plug: (For Laravel <=5.4) Next, you must add the service provider to config/app.php
:electric_plug:
Publish your config file
:fire: And you will be on fire!:fire:
A lot of docs are included in the generated widget file so it is not needed to memorize or even read the rest of this page. You can jump right-in and start using it.
Overview:
This package helps you in:
-
Page Partial Caching
-
Clean up your Controllers Code
-
Minify HTML
-
Easily provide page partials for varnish or nginx for ESI caching
-
Integrated with laravel-debugbar package
-
Renders your widget as HTML or JSON
When to use this package?
This concept (this design pattern) really shines when you want to create tall web pages with multiple sections (on sidebar, menu, carousels ...) and each widget needs separate sql queries and php logic to be provided with data for its template. Anyway installing it has minimal overhead since surprisingly it is just a small abstract class and Of course you can use it to refactor your monster code and tame it into managable pieces or boost the performance 4x-5x times faster! :dizzy:
What is a widget?
You can think of a widget as a blade partial (which know how to provide data for itself.)
You can include @widget('myWidget')
within your blade files and it will turn into HTML
!!!
So you can replace @include('myPartial')
with @widget('myWidget')
in our laravel applications.
:gem: Technical Features:
:small_blue_diamond: 1. It optionally caches the output
of each widget. (which give a very powerful, flexible and easy to use caching opportunity) You can set different cache config for each part of the page. Similar to ESI
standard.
:small_blue_diamond: 2. It optionally minifies
the output of the widget.
:small_blue_diamond: 3. It shows debug info for your widgets as html title="" attributes.
:small_blue_diamond: 4. php artisan make:widget command
:small_blue_diamond: 5. It helps you to have a dedicated presenter class of each widget to clean up your views.
:small_blue_diamond: 6. It extends the Route facade with Route::jsonWidget
, Route::widget
What happens when your write @widget('SomeWidget') in your views
Given that we have disabled caching in the widgetize config file...
1 - It first looks for "SomeWidget" class to get config from.
2 - Then calls the widget's controller method and gets some data from it.
3 - Using that data it "compiles" (in other word "renders") the blade file ($template). (to produce some html)
4 - (If caching is enabled for the widget) it puts a copy of the resulting html in cache, for future use.
5 - At last, it returns the final HTML. (or maybe json)
"Widgets" vs. "View Composers":
You might think that "view composers" are already doing the job, so why "widgets" ?
1- The worst thing about view composers is you never know which composer is attached to a @include not to mention other members of your team.
2- You have no way of passing data to the compose() method from your view. They receive a \Illuminate\View\View object. so they can not be re-used to expose json data. widgetize designed to provide fully freedom and resuability for widget-controllers.
3- They offer no caching out of the box.
:bulb: Sample Code:
How to generate a widget?
You can use :
php artisan make:widget MyWidget
to make your widget class.
Sample widget class :
App\Widgets\MyWidgetView.blade.php :
Ok, Now it's done! We have a ready to use widget. let's use it...
Then how to use that widget?
In a normal day to day view (middle-end):
An other way to think of @widget() in your blade files :
What is the slot?
Slots help you position your HTML or blade code in a widget, and allow the parent widget to arrange it, and improves your widget reusability.
How to define a slot?
To use the slot, you should use instead of and close the directive , Then define your slot middle of it. Look at the syntax:
also, you can pass your data:
How to use the slot?
App\Widgets\MyWidgetView.blade.php :
:book: Documentation:
:earth_africa: Global Config:
You can set the variables in "config/widgetize.php" file to globally set some configs for you widgets and override them per widget if needed. Read the docblocks in config/widgetize.php file for more info.
:blue_car: Per Widget Config:
public $template (string)
If you do not set it,By default, it refers to app/Widgets folder and looks for the 'widgetNameView.blade.php' (Meaning that if your widget is
app/Widgets/home/recentProducts.php
the default view for that isapp/Widgets/home/recentProductsView.blade.php
) Anyway you can override it to point to any partial in views folder.(For example:public $template='home.footer'
will look for resource/views/home/footer.blade.php) So the entire widget lives in one folder:| app\Widgets\Homepage\RecentProductsWidget.php
| app\Widgets\Homepage\RecentProductsWidgetView.blade.php
public $controller (string)
If you do not want to put your data method on your widget class, you can set
public $controller = App\Some\Class\MyController::class
and put yourpublic data
method on a dedicated class.(instead od having it on your widget class)
or you may also refrence it like this :
public $controller = [\App\Some\Class\MyRepo::class, 'myMethod'];
public $controller = '\App\Some\Class\MyRepo@myMethod';
public $presenter (string)
If you do not want to put your present method on your widget class, you can set
public $presenter = App\Some\Class\MyPresenter::class
and put yourpublic present
method on a dedicated class.The data returned from your controller is first piped to your presenter and then to your view.(So if you specify a presenter your view file gets its data from the presenter and not the controller.)
public $cacheLifeTime (int)
If you want to override the global cache life time (which is set in your config file).
value | effect |
---|---|
-1 | forever |
'forever' | forever |
0 | disable |
1 | 1 minute |
public $cacheTags (array)
You can set tags
public $cacheTags = ['tag1','tag2']
to target a group of widgets and flush their cache. using the helper function :
This causes all the widgets with 'someTag' or 'tag1' to be refreshed.
Note: Tagging feature works with ALL the laravel cache drivers including 'file' and 'database'.
public $cacheView
In case you want your view to be real-time but your controller results to be cached, set this to
false
. defalut value istrue
.
public function cacheKey
If you want to explicitly define the cache key used to store the html result of your widget, you can implement this method.
public function extraCacheKeyDependency
It is important to note that if your final widget HTML output depends on PHP's super global variables and you want to cache it,Then they must be included in the cache key of the widget.
You may want to look at the source code and read the comments for more information.
Tip: If you decide to use some other template engine instead of Blade it would be no problem.

Single Responsibility Prinsiple
Q&A
Q&A:How to expose only a widget HTML content from a url ?
A GET
request to /some-url/{a}/{b}
will see the widget.
a and b parameters are passed to widget controller.
jsonWidget
will expose the cached data returned from the widget's controller.
Q&A:How to reference widget controllers from routes ?
This way you can also expose your data as json for client-side apps.
* It is important to put \
before App
when you want to refer to a class outside the Http\Controller
folder.
