Wordpress My first Wordpress Autoptimize Gzip Companion Plugin !

Autoptimize Gzip Companion Wordpress Plugin

When I first set out to do benchmark comparisons against a Wordpress OceanWP themed site, I didn't realise I would be creating my first ever Wordpress plugin

Autoptimize by default only minifies and combines CSS and JS files. It doesn't do any pre-gzip compression of those optimised files.

I asked Frank Goosens the author of Autoptimize if that was possible and he pointed me to an Autoptimize API hook to be able to add an add_filter to enable pre-gzip compression of optimised files. I could hack the Wordpress function.php to add the add_filter or create my own Wordpress plugin for this. Never created a Wordpress plugin, but thought I'd give it a go and so Autoptimize Gzip Wordpress plugin was born https://github.com/centminmod/autoptimize-gzip

End result is with Autoptimize Gzip Wordpress plugin activated, Autoptimize CSS/JS files have pre-gzip compressed versions which are automatically served since Centmin Mod Nginx is configured with gzip_static directive enabled out of the box

Edit actually this feature was mentioned in FAQ at Autoptimize

Update: Feb 25, 2019

Heads up Autoptimize has plans to formally add brotli pre-compression support Create brotli version of cached files by willstocks-tech · Pull Request #237 · futtta/autoptimize which will be enabled when you install my Autoptimize-gzip Wordpress Plugin once added

You will need to be using Centmin Mod 123.09beta01 and enable PHP compression extension support for PHP_BROTLI='y' at least as outlined at https://community.centminmod.com/th...-extensions-by-default-in-123-09beta01.16616/ and ensuring they have Nginx Brotli module enabled via NGXDYNAMIC_BROTLI='y' and NGINX_LIBBROTLI='y' variables prior to Centmin Mod Ngixn recompiles - which will also install Brotli library required to do the actual Brotli compression.

Update: May 7, 2019

Added native Autoptimize Gzip companion plugin support into centmin.sh menu option 22 wordpress auto install - details on enabling it outlined at https://community.centminmod.com/th...2-nginx-vhost-routines-in-123-09beta01.17451/

So who else has given my Autoptimize Gzip Wordpress companion plugin a try centminmod/autoptimize-gzip ?

Mrbo · Sep 25, 2018

Hi! Thanks for this plugin. Looking forward to try this the coming days after I´ve set up a new server, properly this time. Will get back with feedback soon

Qu Don · Oct 14, 2018

Does this have to be used independently or does it need Autoptimize plugin installed as well

eva2000 · Oct 14, 2018

It need Autoptimize plugin installed as well

Heads up one user asked about autoptimize doing pre-compressed brotli compressed css/js assets for wordpress installs and seems Frank author of autoptimize shared some untested code alterations which enable pre-compressed brotli assets if brotli php extension was detected/installed. So I tested thise code alteration and so far seems to work. Discussion and instructions at Add brotli static · Issue #2 · centminmod/autoptimize-gzip

Thank you. It works great!

eva2000 · Nov 10, 2018

Glad to hear my plugin has been useful

upgrade81 · Nov 13, 2018

fantastic, I try it now.

upgrade81 · Nov 14, 2018

tried and everything works!

the only thing is that it does not create static files concerning brotli compression.
I followed your procedure to install the php module.

did you modify autopimize code outlined at Add brotli static · Issue #2 · centminmod/autoptimize-gzip ?

Jay Chen · Nov 15, 2018

Does it make sense to install this plugin when I'm using cloudflare?
I believe cloudflare compresses the files before storing them.
So any files serve from cloudflare will be compressed.

no! what I miss, where should it be inserted? in which wordpress file?

upgrade81 · Dec 5, 2018

I have not yet figured out where this code should be inserted.
In the function it does not work.

Code:

if ( apply_filters( 'autoptimize_filter_cache_create_static_gzip', false ) ) {
    // Create an additional cached gzip file.
    file_put_contents( $this->cachedir . $this->filename . '.gz', gzencode( $data, 9, FORCE_GZIP ) );
    // Create an additional cached brotli file if brotli_compress exists
    if ( function_exists( 'brotli_compress' ) ) {
       file_put_contents( $this->cachedir . $this->filename . '.br', brotli_compress( $data ) );
    }
}

Thank you, so if you update the plugin you probably lose the change.
Good to know.

upgrade81 · Dec 6, 2018

inserted below in various ways but does not work, crash wordpress.

Code:

     if ( false === $this->nogzip ) {
            // We handle gzipping ourselves.
            $file    = 'default.php';
            $phpcode = file_get_contents( AUTOPTIMIZE_PLUGIN_DIR . 'config/' . $file );
            $phpcode = str_replace( array( '%%CONTENT%%', 'exit;' ), array( $mime, '' ), $phpcode );

            file_put_contents( $this->cachedir . $this->filename, $phpcode );
            file_put_contents( $this->cachedir . $this->filename . '.none', $data );
        } else {
            // Write code to cache without doing anything else.
            file_put_contents( $this->cachedir . $this->filename, $data );
            if ( apply_filters( 'autoptimize_filter_cache_create_static_gzip', false ) ) {
