About the Book



Ethereum is platform for building decentralized applications.


Book content

This book is collection of standalone tutorials.

This means that each tutorial contains minimum amount of code needed to explain specific functionality.

This is in contrast to building a single application where each new functionality is added on top of already explained ones.

Each tutorial has minimum amount of supporting text making emphasis on the code example to do the explaining.


How to use this book

This book can be used as an introduction to Meteor framework covering all of the basic core functionalities.

In addition book will be updated with more tutorials covering more specific subjects.

Book is also intended as Just In Time Support so that user can learn what it needs when it needs it.

This is why tutorials are standalone and minimalistic focusing only at one problem at the time.

You should however first go through the main features of Meteor to familiarize yourself with the core concepts.

This can be done by first going through the main chapters as deep as you see fit.

Then later you can come back to explore other more specific chapters as you need them.

"Things are only as complicated as they are badly explained" 

Proper documentation is essential to avoid struggle and frustration when working with simple things that only seem complicated by not being properly documented and explained. 



"Working example is worth thousand words"

Just like the picture is worth thousand words the same goes for the working example. Documentation in the form of working examples is proved to be the fastest and the most effective way of transferring knowledge. Sometimes an example is all you need to get the things done. And if there are some accompanying comments that explain what is going on even better. This approach is used in this book. This results in fast learning and the ability to apply tutorials when you need them in the spirit of Just In Time Support. 

I wish you rapid learning!
