Async / Defer JS
================

[](#async--defer-js)

"Async Defer JS" is a module which adds a configuration that says what HTML scripts should get an "async" or "defer" attribute.

It acts upon scripts added as page assets. A script which is added by a third party through some other way than a page asset won't get the "async" or "defer" attribute even if it matches one of the regular expressions configured.

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

[](#installation)

Run the following command in the root of Magento 2.

```
$ composer require weprovide/magento2-module-async-defer-js

```

Once installed the only thing left to do is actually enable it.

```
$ bin/magento module:enable WeProvide_AsyncDeferJs
$ bin/magento setup:upgrade --keep-generated

```

Configuration
-------------

[](#configuration)

In `System > Configuration > Advanced > Developer > JavaScript Settings` two configuration settings can be seen. One of them is the regular expression used for the `async` HTML attribute, the other for `defer`.

There is also an other setting, the `Check block scripts for "async" and "defer"` which defaults to "No", and can be enabled when there is also a need to apply `async` and `defer` to scripts inside blocks.

The following regex can be used to match all scripts accept the require.js: `^((?!require.js).)*$`
