 1 | ## Laravel PDF VIEWER
 2 | 
 3 | [![Latest Stable Version](https://poser.pugx.org/davcpas1234/laravel-pdf-viewer/v/stable)](https://packagist.org/packages/davcpas1234/laravelpdfviewer)
 4 | [![License](https://poser.pugx.org/davcpas1234/laravel-pdf-viewer/license)](https://packagist.org/packages/davcpas1234/laravelpdfviewer)
 5 | [![Build Status](https://scrutinizer-ci.com/g/davcpas1234/laravel-pdf-viewer/badges/build.png?b=master)](https://scrutinizer-ci.com/g/goodnesskay/LARAVEL-PDF-VIEWER/build-status/master)
 6 | 
 7 | > This package is meant to help with viewing portable document file(PDF) on the web seamlessly when developing with Laravel. The package makes use of [ViewerJS](http://viewerjs.org) 
 8 | 
 9 | ## Requirement
10 | 
11 | - [PHP](https://php.net) 5.6+ 
12 | - [Composer](https://getcomposer.org)
13 | - Pdf files
14 | 
15 | ## Installation
16 | To install into your project, run the command below in your terminal.
17 | 
18 | ```
19 | composer require davcpas1234/laravelpdfviewer
20 | ```
21 | 
22 | Once the package is done being installed, register the service provider. Open `config/app.php` and add the following to the `providers` key.
23 | 
24 |  ```
25 |  Davcpas1234\LaravelPdfViewer\LaravelPdfViewerServiceProvider::class,
26 |  ```
27 |  
28 |  ## Configure
29 |  Run this in your terminal:
30 |  ```
31 | php artisan vendor:publish --provider="Davcpas1234\LaravelPdfViewer\LaravelPdfViewerServiceProvider" 
32 | ```
33 | It will publish a folder named `laraview` to the root folder of your project.
34 | 
35 | ##  How it Works
36 | Simple!!! After installations and configurations have been carried out successfully, add the code below to your html file
37 |  ```
38 |  {{ asset('/laraview/#../folder-name/the-pdf-file.pdf') }}
39 | 
40 | ```
41 | It should look like this:
42 | ```
43 | <iframe src ="{{ asset('/laraview/#../pdf/test.pdf') }}" width="1000px" height="600px"></iframe>
44 | ```
45 | Then, you should have something like this:
46 | 
47 | ![Goodness Kayode Laravel-pdfviewer](https://cloud.githubusercontent.com/assets/16525886/26499445/9483e444-422a-11e7-81cf-9569b8f33669.png)
48 | 
49 | 
50 | **Note:** 
51 | > After `#../` in `{{ asset('/laraview/#../folder-name/the-pdf-file.pdf') }}`, what should follow is the folder name of the pdf files in the public 
52 | folder then, the pdf file name can follow.
53 | 
54 | 
55 | 
56 | ## Contribute
57 | 
58 | You can `fork` this package, `contribute` and `submit a pull request`. I will really love it.
