However, we wanted to showcase some of the lesser known contenders, now for full disclosure the above links were affiliate links with Amazon, but the links below will not be and in no shape or form will we benefit on you checking them out, in-fact all the books are available for free online.
Currently the book is marked as around half way finished, the chapters yet to be written seem to be on Node but the chapters that are there are pretty solid. Since it’s a work in progress the book is available as pay what you want on Leanpub, the source book is also available via GitHub.
All in all, it’s a solid introduction for someone who isn’t already a developer.
