README
"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
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
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).)*$
