This is an easy to understand example based tutorial aimed at those who know a little of Go and nothing of webdev and want to learn how to write a webserver in Go. You will create a to do list application as you advance the chapters.

Please use the front end folder in the code folder to get the index.html of the Tasks project and work on it while reading this tutorial.

We have a YouTube series and a fully functioning web application as supporting documents. Tasks is the application which you'll as you read into the book

If you prefer learning by watching, YouTube series. The code corresponding to the YouTube series is available here. The code is published as branches, each video has a particular branch.

This guide is a part of the Multiversity initiative. The aim is to have high quality open source tutorials along with screencasts.

I got feedback from a reddit user that maybe it is too early for me to start writing this book. Decades ago, a young student from the University of Helsinki had an endless debate with Andrew Tannenbaum on comp.minix. It was about monolithic kernels. Had the student listened to Andrew Tannenbaum, the world probably would not have had Linux. This is the whole point of open source projects, a little initiative from everyone goes a long way. I would like to thank everyone who gave their suggestions on reddit and HN.

• Through this book we want to teach how to develop web applications in Go. We expect the reader to know the basics of Go but we assume the reader knows nothing about how to write web applications.
• The book shall comprise of chapters, if the topic is huge and doesn't fit into one chapter, then we split into multiple chapters, if possible.
• Each chapter should be split into logical parts or sections with a meaningful title which'll teach the reader something.
• Every concept should be accompanied by the Go code (if there is any), for sneak peek type sections write the Go pseudo code, writing just the necessary parts of the code and keeping everything else.
• The code shouldn't be more than 80 characters wide because in the PDF versions of the book the code is invisible.
• Brevity is the soul of wit, please keep the description as small as possible. This doesn't mean we skip it, but try to explain it in as simple words as possible. In such cases do explain the concept.
• In the todo list manager which we are creating, we'll strive to implement as much functionality as possible to give a taste of practical Go programming to the reader. In cases where we re-implement stdlib stuff, we should mention it clearly.
• The main title should have one #, sections should have 2 #'s sub section should have 4 and notes should have 6 #'s (note should have a title too).
• Multi-line code should use syntax fencing, single line of code can be indented using tabs or by backticks.
