Getting the image URL from a field_image on a node So I have this Node:

object(Drupal\node\Entity\Node)[1862]
  protected 'values' =&gt; 
    array (size=17)
      'vid' =&gt; 
        array (size=1)
          'x-default' =&gt; string '7' (length=1)
      'langcode' =&gt; 
        array (size=1)
          'x-default' =&gt; 
            array (size=1)
              0 =&gt; 
                array (size=1)
                  'value' =&gt; string 'en' (length=2)
      ... (more fields)
      'field_image' =&gt; 
        array (size=1)
          'x-default' =&gt; 
            array (size=1)
              0 =&gt; 
                array (size=5)
                  'target_id' =&gt; string '1' (length=1)
                  'alt' =&gt; string '' (length=0)
                  'title' =&gt; string '' (length=0)
                  'width' =&gt; string '150' (length=3)
                  'height' =&gt; string '120' (length=3)


Now the field_image has an array with x-default and some basic image data. How do I show the image, or create a link to the image inside the Twig template?
Here is an update version of for this answer after 8.0.x. This base on @joelpittet comment.

{{ file_url(node.field_image.entity.fileuri) }}
