# Nodes

Nodes are the main content type in Drupal. It's the most common entity that we use in Drupal.

### Get Current Node information

```php
$node = \Drupal::routeMatch()->getParameter('node'); // get node

$node_type = $node->getType(); // Node type
$node_bundle = $node->bundle(); // Node type

$nid = $node->id(); // Node id

$title = $node->getTitle(); // Node title
```

### Get current Node information on preview page

```php
  $routeMatch   = \Drupal::routeMatch();
  $node_preview = $routeMatch->getParameter( 'node_preview' );
```

### Get info of a specific Node - NODE::load()

```php
$NODE_TITLE =  Node::load(ID)->getTitle(); // Node title
```

### Query Nodes

There are two methods that I use to query nodes, the first one is the `EntityQuery` and the second one is the `EntityTypeManager`. These two are almost exactly the same, if you were to look at the code, you would see that they are using the same methods. The only difference is that the `EntityTypeManager` is a bit more flexible and it's easier to use.

#### Get info of a specific Nodes - EntityQuery

```php
$node_ids = Drupal::entityQuery('node')
      ->condition('type', CONTENT_TYPE)
      ->condition('FIELD_NAME', FIELD_ID)
      ->execute(); // Get all the node ids that match these conditions
$nodes = Node::loadMultiple($node_ids); // All the nodes in an assoc array
```

#### Get info of a specific Nodes - EntityTypeManager

```php
$node = \Drupal::entityTypeManager()->getStorage('node')
        ->getQuery()
        ->condition('nid', $nid, '=')
        ->condition('type', 'blog')
        ->condition('status', 1)
        ->sort('nid', 'ASC')
        ->range(0, 1)
        ->execute();

$node = array_values($node);
$node = $node[0];

// Or we could use $node = reset($node)

$titulo =  Node::load($node)->getTitle(); // Title

$link = \Drupal::service('path_alias.manager')
          ->getAliasByPath('/node/' . $node);  // Relative url
```
