Taught by a university professor with two decades in both teaching and industry, this course walks through everything needed to build a secure, fast web application in Go – starting with the language itself and ending with a complete project.

From language basics to a real project

You'll begin with an overview of Go before covering the front-end pieces you need alongside it: HTML5, JavaScript and its modules, and CSS for styling. The centerpiece is a full booking and reservation system for a bed & breakfast, where visitors can search availability by date and book online while the owner manages reservations from a secure admin area.

Who it's for

The material works whether you're completely new to web development or you already build web apps and want to add Go to your toolkit. By the end you'll have shipped a functional, secure application and gained a solid working understanding of the Go language.

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.

Who teaches Building Modern Web Applications with Go (Golang)? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
