An extension for [Twig](https://twig.symfony.com/) that allows to defer block rendering.

Installation
------------

[](#installation)

```
composer require rybakit/twig-deferred-extension
```

> *Note that this extension requires Twig 3 or above. If you need support for older versions of Twig, please refer to the [legacy repository](https://github.com/rybakit/twig-extensions-deferred-legacy).*

Initialization
--------------

[](#initialization)

```
use Twig\DeferredExtension\DeferredExtension;
use Twig\Environment;

...

$twig = new Environment($loader);
$twig->addExtension(new DeferredExtension());
```

Simple example
--------------

[](#simple-example)

```
{% block foo deferred %}
    {{ bar }}
{% endblock %}

{% set bar = 'bar' %}
```

The `foo` block will output "bar".

Advanced example
----------------

[](#advanced-example)

Just for example purposes, first create a [global twig variable](http://twig.sensiolabs.org/doc/advanced.html#globals):

```
use Twig\Environment;

...

$twig = new Environment($loader);
$twig->addGlobal('assets', new \ArrayObject());
```

Then build the following set of templates:

```
{# layout.html.twig #}

        ...

        {% block content '' %}

        {{ assets.append('/js/layout-header.js') }}

        {% block javascripts deferred %}
            {% for asset in assets %}

            {% endfor %}
        {% endblock %}

        {{ assets.append('/js/layout-footer.js') }}

{# page.html.twig #}
{% extends "layout.html.twig" %}

{% block content %}
    {{ assets.append('/js/page-header.js') }}

    {% if foo is defined %}
        {{ include("subpage1.html.twig") }}
    {% else %}
        {{ include("subpage2.html.twig") }}
    {% endif %}

    {{ assets.append('/js/page-footer.js') }}
{% endblock %}

{# subpage1.html.twig #}
{{ assets.append('/js/subpage1.js') }}

{# subpage2.html.twig #}
{{ assets.append('/js/subpage2.js') }}
```

The resulting html will be the following:

```
>

        ...

```

Block overriding
----------------

[](#block-overriding)

```
{# index.twig #}
{% extends "base.twig" %}
{% block foo %}foo is not deferred anymore{% endblock %}
{% block bar deferred %}bar is deferred now{% endblock %}

{# base.twig #}
{% block foo deferred %}foo is deferred{% endblock %}
{% block bar %}bar is not deferred{% endblock %}
```
