Nim days book is about my journey using Nim and creating useful/practical things with it including:

• ini parser
• bencode parser
• links checker
• tictactoe (commandline and gui)
• testing framework
• build system
• tcp router
• redis parser
• redis client
• assets bundler
• terminal table
• dotfiles manager
• urlshortening application

This book is influenced by the great books Practical Common Lisp, Real World Haskell and I'm planning to follow the same model of having the book available for free online.
