## Features
- Friendly Interface
- Ease of set titles and meta tags
- Ease of set metas for twitter and opengraph

## Installation
### 1 - Dependency
The first step is using composer to install the package and automatically update your `composer.json` file, you can do this by running:
```shell
composer require artesaos/seotools
```
> **Note**: If you are using Laravel 5.5, the steps 2 and 3, for providers and aliases, are unnecessaries. SEOTools supports Laravel new [Package Discovery](https://laravel.com/docs/5.5/packages#package-discovery).

### 2 - Provider
You need to update your application configuration in order to register the package so it can be loaded by Laravel, just update your `config/app.php` file adding the following code at the end of your `'providers'` section:

> `config/app.php`

```php
// file START ommited
    'providers' => [
        // other providers ommited
        Artesaos\SEOTools\Providers\SEOToolsServiceProvider::class,
    ],
// file END ommited
```

#### Lumen
Go to `/bootstrap/app.php` file and add this line:

```php
// file START ommited
	$app->register(Artesaos\SEOTools\Providers\SEOToolsServiceProvider::class);
// file END ommited
```

### 3 - Facade

> Facades are not supported in Lumen.

In order to use the `SEOMeta` facade, you need to register it on the `config/app.php` file, you can do that the following way:

```php
// file START ommited
    'aliases' => [
        // other Facades ommited
        'SEOMeta'   => Artesaos\SEOTools\Facades\SEOMeta::class,
        'OpenGraph' => Artesaos\SEOTools\Facades\OpenGraph::class,
        'Twitter'   => Artesaos\SEOTools\Facades\TwitterCard::class,
        // or
        'SEO' => Artesaos\SEOTools\Facades\SEOTools::class,
    ],
// file END ommited
```


### 4 Configuration

#### Publish config

In your terminal type
```shell
php artisan vendor:publish
```
or
```shell
php artisan vendor:publish --provider="Artesaos\SEOTools\Providers\SEOToolsServiceProvider"
```

> Lumen does not support this command, for it you should copy the file `src/resources/config/seotools.php` to `config/seotools.php` of your project

In `seotools.php` configuration file you can determine the properties of the default values and some behaviors.

#### seotools.php

- meta
 - **defaults** - What values are displayed if not specified any value for the page display. If the value is `false`, nothing is displayed.
 - **webmaster** - Are the settings of tags values for major webmaster tools. If you are `null` nothing is displayed.
- opengraph
 - **defaults** - Are the properties that will always be displayed and when no other value is set instead. **You can add additional tags** that are not included in the original configuration file.
- twitter
 - **defaults** - Are the properties that will always be displayed and when no other value is set instead. **You can add additional tags** that are not included in the original configuration file.

## 5 - Usage

> Facades are not supported in Lumen.

### Lumen Usage

```php
$seotools = app('seotools');
$metatags = app('seotools.metatags');
$twitter = app('seotools.twitter');
$opengraph = app('seotools.opengraph');

// The behavior is the same as the facade
// --------

echo app('seotools')->generate();

```

### Meta tags Generator
With **SEOMeta** you can create meta tags to the `head`

### Opengraph tags Generator
With **OpenGraph** you can create opengraph tags to the `head`

### Twitter for Twitter Cards tags Generator
With **Twitter** you can create opengraph tags to the `head`

#### In your controller
```php
use SEOMeta;
use OpenGraph;
use Twitter;
## or
use SEO;

class CommomController extends Controller
{

    /**
     * @return \Illuminate\View\View
     */
    public function index()
    {
        SEOMeta::setTitle('Home');
        SEOMeta::setDescription('This is my page description');
        SEOMeta::setCanonical('https://codecasts.com.br/lesson');

        OpenGraph::setDescription('This is my page description');
        OpenGraph::setTitle('Home');
        OpenGraph::setUrl('http://current.url.com');
        OpenGraph::addProperty('type', 'articles');

        Twitter::setTitle('Homepage');
        Twitter::setSite('@LuizVinicius73');

        ## Or

        SEO::setTitle('Home');
        SEO::setDescription('This is my page description');
