If you need mini projects/apps to build, check out Craigslist, oDesk, Elance and other sites, that post projects by people looking to hire freelance developers, for the projects in your framework/language. Trim the ideas down to the size of mini project. And, then figure out how you can implement a bare bone MVP on your own using the web framework you are learning.

I recently met a guy who put out a micro site for time zone conversion that he built as exercise while learning web development. He was surprised how many visitors started to come and use his micro site. Since then he has developed 100s of micro sites as part of learning and all supported by ads. It generates him nice chunk of change for the amount of effort he put in.
