About the Book

Web Applications in Go

Table of Contents

  • Introduction to Go
  • Unit testing and Test Driven Development with Go
  • Creating a simple Twitter-like Microblog application ( using Beego Framework )
  • UI templates
  • Styling with Twitter Boostrap
  • Background jobs - processing '@' mentions
  • WebSockets - '@' mention push-style notifications.
  • Search and indexing - processing '#' hashtags
  • Security - using asymmetric encryption for our API and storage
  • Deployment - deploying to Amazon AWS and Google App Engine for Go

The book describes how to build a Twitter-like application, as an example of a real-world web application. To make the example as realistic as possible, we walk the reader through building an application with the following real-world-like features:

  • A user of this application ( that we create in the book) will be able to create/read/update/delete posts. The user will be able to follow other users and view their timeline.
  • An HTML ( web ) view as well as a REST API will be created.
  • The application will be styled using Twitter Bootstrap
  • The application will be able to detect '@' mentions. This will be done via a background concurrent job and the user will be introduced to writing such jobs in Go web applications.
  • The application will push mention notifications using WebSockets. The push notification will be triggered after a mention is detected, as above.
  • The application will allow users to search by '#' hashtag. In this section, the reader will be shown how to handle searching and indexing of text - an important chapter, given (almost) every application today needs to do search.
  • The application we create will introduce the user to Public Key Cryptography ( and it's application to web applications ) by creating an API that will accept JSON encrypted with the server's public key, which the server will then decrypt using it's private key and post the message. The API call from the user to the server will be public-key encrypted. The Go's Box Crypto API - https://godoc.org/code.google.com/p/go.crypt

  • An HTML ( web ) view as well as a REST API will be created using net.http , Gorilla mux, Gorm and Go's templates.
  • The front end will be built using Angular.js and JQuery - however teaching these is outside the scope of the book.

  • Deployment: The user will be walked through deploying the application on Amazon AWS and Google's new Go Runtime Engine - https://developers.google.com/appengine/docs/go/

  • Docker - deploying applications via Docker, which itself is written in Go

Notes
  • The Table of Contents is a little too verbose, will be fixed.
  • The book will be free. If you can pay for it, please do. If you can't/won't that's okay too.
