Description

Learn to write modern, fast, and secure web applications in Google's Go programming language, and learn it from an award winning University professor with 20 years of teaching experience, and 20 years of experience working in the industry as an entrepreneur.

Go is a modern, type safe, compiled, and extremely fast programming language. It it is ideally suited for building safe, scalable, incredibly fast web applications.

This course is well-suited for both absolute beginners, and for developers who already know something about web development, but want to add Go to their toolbox.

We start with an overview of the Go language, and then cover everything you need to get started writing web applications, including an overview of HTML5, a survey of JavaScript and JavaScript modules, how to work with Cascading Style Sheets to make our application look the way we want, and much more.

The major project in this course is building a bookings and reservation system for a Bed & Breakfast. Visitors to our site will be able to search for accommodations by date and make an online reservation, and the site owner will be able to manage reservations from a secure back end.

By the time you finish this course, you will have a solid grasp of what it takes to build a completely functional, secure, and fast web application from the ground up, and you will have a solid understanding of the Go programming language.
