Yesod is based on templates, to generate instances for listed entities, and dynamic content process functions through Template Haskell constructs called QuasiQuotes whose content is translated to code expressions by metaprogramming instructions. Light-weight syntax A lot of web development is boilerplate.

But after writing a small application with Snap which is modular and very understandable for newcomer I could easily identify the same patterns in Yesod and write Yesod applications easily with greate help from Yesod book.

Agree, I think the Yesod book is great and cover everything you need get you started: It can either accept input from standard in, or by a list of named files. The good stuff about Yesod iseven if you don’t like it, it’s quite easy to remove and replace the bits you don’t like.

So thanks for the yesod team for keeping up this nice and haskfll framework. Hi Folks, This is my second attempt at learning Haskell, and I want to know if I know enough of the language to stop looking at learning resources and start actually building things while learning.
