#### Preliminary 
There are web systems that need generates documents, cards, registrations or custom templates to users.  <br>
DomPDF is a package created and developed by Barryvdh that allows generate pdfs, just display in browser or download.
#### Install package: 
First open **“composer.json”** file of your project and add in section require the next line: 
<br>
**"barryvdh/laravel-dompdf": "^0.8.2",**
<center>

<h6> You could use another DomPdf version greater than 0.6 </h6>
</center>
 <br> 
Then, open terminal or console and go to the root directory of project. In my case:  
![tutorial1.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1521931747/qwqhlguyccg0wcqmdlpq.png)
<h6> cd C:\xampp\htdocs\consultoria </h6> 
<br>
 Run the following command 
<h5> $ composer update </h5>

![tutorial5.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1521931941/mt1nkq5kpfznooqbtavr.png)
<h6> $ means instructions to run in console. </h6>
> This command checks if there are new dependencies in the file composer.json and update your system/application.

Go to <strong>“config” </strong> folder, later open <strong> “app.php”  </strong> file and write in service “providers”
 <h6> Barryvdh\DomPDF\ServiceProvider::class, </h6>
![tutorial3.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1521932350/sqy6fuk2mpnm2uzztuvk.png)
>Providers enables that new class in application's service container.

<br> 
In the same file <strong> “app.php” </strong> in <strong> “aliases" </strong> section, add this line about facade: 
<h6>  'PDF' => Barryvdh\DomPDF\Facade::class, </h6>

### Creating PDFs:
After to prepare the environment, your system is ready to generate pdfs. 
#### Using a controller:
1. Create a route to a function that generates the pdfs, remember 
<h6>Route::get('name_of_your_route/{your_parameters}','name_of_controller@controllers_method'); </h6>

![tutorial10.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1521933395/szbtq6lmwsd29rdrumjm.png)

 The method in your controller should be

![tutorial11.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1521933710/hdkc72psjabjhexfr9xq.png)
<h6> public function pdf($your_parameters) <br>
{ <br>
$variables=$your_parameters; <br>
$pdf=PDF::loadView(‘views_name’,compact(‘$variables)); <br>
return $pdf->stream(‘pdf’); <br>
} </h6>
We need declare a variable of type PDF.  This variable is responsible to generate a PDF of our view.  
In the App variable (pdf) is necessary include another data that user requests since a form or to the database, **compact** is the word used, compact creates an array with values.  Some people use “with” but in my case it doesn’t work properly. <br>
In last setence is used the method <strong>stream</strong> to encodes the display of PDF in your browser without download. If you prefer download replace stream for download.  
 <h6>
#### Considerations: 
- When you create a blade view for a pdf, you should only write html and css setences. Don’t include javascript or css frameworks.

<h6>My view </h6>

#### Result PDF:
- The access to the pdf since browser using your route:
**localhost/name_of_your_project/public/name_of_your_route**
