Informations about the package robo-js-minify
Robo JS Minify
This Robo task performs a minification of your JS content.
This task performs the minification using matthiasmullie/minify library.
Requirements
- PHP >= 7.1.0
- Robo
Installation
You can install this Robo task using composer.
The recommended way to install composer packages is:
Using the task
You can load the task in your RoboFile using the LoadJsMinifyTasksTrait
trait:
The only argument the taskJsMinify()
takes is an array ($destinationsMap
) which maps the source files to the destination files : it will load the assets/js/main.js, do its magic and put the final content in assets/min/js/main.min.js and do the same for all of the other files.
GZIP compression
In addition to minifying your files, you can gzip them. You can enable gzip using the enableGzip()
method :
By default, files will be compressed using the maximum level (which is 9). You can customize the compression level using the method setGzipLevel()
:
The setGzipLevel
accepts values from -1
to 9
. If you use -1
, the default compression level of the zlib library will be used.
0
means you do not want any compression and 9
is the maximum level of compression.
If you use a value that is out of these bounds, the maximum compression level will be used.
Chained State support
Robo includes a concept called the Chained State that allows tasks that need to work together to be executed in a sequence and pass the state of the execution of a task to the next one. For instance, if you are managing assets files, you will have a task that compile SCSS to CSS then another one that minify the results. The first task can pass the state of its work to the next one, without having to call both methods in a separate sequence.
The robo-js-minify task is compatible with this feature.
All you need to do is make the previous task return the content the robo-js-minify task should operate on using the data
argument of a Robo\Result::success()
or Robo\Result::error()
call. The passed data
should have the following format:
In turn, when the robo-js-minify task is done, it will pass the results of its work to the next task following the same format.
Preventing the results from being written
By default, the robo-js-minify task writes the result of its work into the destination file(s) passed in the $destinationsMap
argument. If the robo-js-minify task is not the last one in the sequence, you can disable the file writing using the disableWriteFile()
method. The files will be processed but the results will not be persisted and only passed to the response :
