I've started learning symfony framework and I thought that it would be a great practice to build eCommerce site, but I found it difficult finding information about building it.
My questions are: Witch bundles would be useful for building an eCommerce site? Maybe there are some sources where I could find code examples how the pros build their projects?
Sonata Project has several bundles that would aid in the development of your eCommerce website. One of these is specifically for eCommerce.
