It is generally adviced to store module assets inside the module's directory, inside moduleName/public (or whatever you want to name the asset's directory).
Zend Framework 2 unfortunately doesn't support asset publishing for module assets by default. According to MWOP, there was nothing planned ~1 month ago and I guess there still is no real plan (they had probably a lot of work to get the stable version ready). (But, some day, they are going to address this issue.)
As my ZF2 app is growing and growing, I reached the point where I need to have module-specific assets. At the moment, I maintain them inside the module directories and copy them to the application's public directory. You can imagine that this method is error-prone and exhausting.
How do you handle this problem? Is there maybe a simple solution to this issue with little coding effort? My project plan doesn't allow me to create a complex asset handling on my own. Is there a recommendable, lightweight asset framework compatible to ZF2? I've already considered creating symlinks but I don't think this would be the best solution because it would require some additional web server configuration (FollowSymlinks) and additional maintenance work (the app is developed locally and deployed on a remote server).
Thanks in advance.
This has been discussed before in many places and it comes down to three ways to manage this.
Copy and Paste the assets into the public/ directory
Use symlinks
Use an asset loading module like assetic
A simple solution would be to make the copying of assets part of you build process.
Another question was already asked How to merge Zend Framework 2 module public directories for info.
I know this is pretty old, but I wanted to add this information for other readers.
Now there's also a module for this, which has been fully tested and is being used (and even depended on) by many modules.
Check it out here: https://github.com/RWOverdijk/AssetManager
Hope this helps.
There is also fourth option. Use a directory Alias in VirtualHost configuration.
