The main feature of this component is to concatenate and compress [GZIP] JS and CSS files listed in "AssetBundle" and allow application an option to upload them to AWS S3 bucket directly from minify folder on file generation.And present copressed files from S3 bucket to browser. Concatenation and compression of all files will be done on first time loading after deployment, for all the next requests assets will only be requested from S3 bucket.Optionally console request can also be sent to have all the assets coming from S3 bucket directly. Console request must be part of continuous deployment script.
- It works with layouts. For instance different layouts can have different JS & CSS files which can be listed in different AssetBundle.
- There should be only one main AssetBundle which has all other asset bundles as dependecies. Please check here how I have managed my assets.
- All JS & CSS files [ mostly JS pluggins ] used in particular layout whether it belongs to a particular page which only required on widget initialization must be also added at in the main Asset file under dependency.
The preferred way to install this extension is through composer.
Either run
composer require "processfast/yii2-minify-view:~1.18"or add
"processfast/yii2-minify-view": "~1.18",
to the require section of your composer.json file.

By giving dependencies and loading all JS/CSS files throught web application in a uniform sequence will create uniform minified JS/CSS files from extention for all pages as all pages have same JS/CSS files with same sequence. As the final name of JS/CSS file depends on the file content and file path so it is important to have configuration in this way.
This is just example of my "bundles-minify.php" which handles dependency you can create yours on the basis of your asset bundles.

- Another thing application needed folder names generated from backend/frontend have same name. As backend path will have "ROOT/backend/../assets" name can be different to solve that added this fix. Which will create same named folders for backend and frontend. Folder names will be same.

This will be helpfull if you have continuous deployment, now you want to generate all the assets from a console request and compress and concate them and upload them to S3 bucket. Just need to add this controller and call "php asset-minify/init" in continuous deployment script.
