Asset management and php caching system using uglifyjs for javascript assets

v0.5.3 2019-02-23 14:35 UTC


Please note: This is a custom caching framework designed both to play around with using uglify js and uglify css, and to be used for a custom website not suited for standard caching systems. In production you probably will want to use other caching frameworks such as assetic.

Version 0.1 was a proof of concept to test if it worked. Since this does indeed appear to work im going to rework it to fill a number of potential objectives:

  • Ability to state which files you want to crunch and load
  • One file will be produced per set of crunch files. If you crunch A, B, and A+B they will exist as 3 separate crunch files
  • The output of crunch A and B will not be used for A and B, and will be completely separate
  • If the combined crunch is not available on the filesystem an exception will be thrown
  • In debug mode the raw files will be loaded instead of the crunched file
  • In debug mode, every time the raw files are loaded they are crunched
    • These crunched files will be saved as a new revision and will allow easy deployment calling the specific crunch method
    • When crunching files manually it will check for these new cached files and use them if present to speed up cache deployment
    • Some way to know which crunched files have new revisions you could deploy
  • CSS files will be supported to merge css into a single file
  • Uglify css will need to be ported over similarly to uglify js
    • maybe add some kind of similar interface, etc?
    • maybe allow any kind of crunching software to be plugged in?
  • Store a list of previously crunched files, and their current file somewhere "nice"
    • Allow a user to recrunch everything if its changed using above store
    • Allow marking a crunch as "stale" after a file has been removed from the filesystem
    • Some way to view this potentially?
  • Have some basic versioning of crunched files

Current Issues

Possible implementation

  • JSON store to store all the data about the files
  • Then export this to a basic php array file used for the main cache
  • JSON file stores all the details such as new files, etc
  • Each time the cache is modified json file is written out as a php file that works as the bootstrap


  • Remove all comments but allow custom comments at the top of the file configurable
  • Allow getting the details of all previously crushed files and their constitutent paths
  • Allow crushing by identifier (using the details of the constituent parts)
  • Allow checking of identifiers to find what hasnt yet been updated (has changes in constituent files)
  • Comment all code
  • Comment all tests
  • Write some more tests
  • Create an example implementation repo?
  • Run speedtests on importing a json file and including the php file? (only used the PHP file including as I have made the assumptions that it will be faster, possibly not true?)
