This course covers the journey of building a Go web application from scratch. We’ll take a real-world use case and build a working app with HTTP endpoints.

Web apps are used in all walks of life. Many tech companies have already adopted Go as the main language for their backends. As a result, there is a high demand for developers who can create them, especially those with expertise in modern technologies like Go and Docker.

This course is a guide for creating RESTful web apps using Go and managing them through Docker. You’ll start with learning about HTTP and how it sends requests and responses to interact with an app’s server. You’ll learn about the basics of Go and its applications in web development. You’ll create an HTTP web server using Go’s popular web framework, Gin. Next, you’ll use Docker to containerize your app and manage its configuration. You’ll finish by learning some best practices that will make your apps easy to debug and maintain, saving costs in terms of time and effort.

By the end of the course, you’ll become an expert in developing containerized web apps in Go that are efficient and easily scalable, and maintainable.

It's the default dependency management tool in Go v1.18.

It uses `go.mod` and `go.sum` to keep track of the dependencies.

A module has to be initialized from `$GOPATH`.

They can be loaded and served at HTTP endpoints by a web server.

A Go program can pass data that could be passed to these HTML files with the help of Gin.

We can't serve both HTML files and regular data via functions in the same app. 

The HTML files have to be static and cannot accept any inputs from the Go program.
