Syllabus

Introduction

An overview of what we are going to do, and a bit about my background.

The advantages of Go over other options.

Go and system resources.

In this lecture, we install Go, an Integrated Development Environment (IDE), and the necessary plugins, and then write a simple "Hello, world" application.

My suggestions for solving problems along the way.

A few useful resources that will help you as you go through the course.

Overview of the Go Language

For Windows users, an alternative to the standard command prompt.

We learn how to use basic variables and functions.

Pointers, and how they are implemented in Go.

We learn how to define our own data types.

Methods: functions with receivers.

Two useful data structures: maps and slices.

Making decisions in our programs.

How to loop over data structures in Go.

Go's useful implementation of interfaces.

Check your understanding of interfaces in Go

Go's package management system.

How to pass data to (and between) goroutines.

Working with Javascript Object Notation (JSON) files.

How to write tests in Go.

Building a Basic Web Application

An overview of what happens when you visit a web page.

We convert our simple "Hello, world" program to a basic web application.

Go 1.16 requires modules for a lot of things. Let's enable them.

We improve our "Hello, world" web application by creating additional handlers and routes.

A basic introduction to error checking.

We modify our web application to serve actual HTML pages, instead of simply writing text to the browser window. Pages are served using Go's template/html package.

A note for Windows Users

We organize our application a bit more intelligently, and add Bootstrap to our HTML templates (which we will be using in more detail later in the course).

We enable Go Modules, and move core components of our application into packages.

Working with Layouts

Building a simple template cache

Building a more complex template cache

A note about the next lectures

We set up an application wide configuration, so we can share information with our packages as needed.

A bit more about our site wide configuration logic.

Making our template cache more useful.

A note about the next lecture

We go through the process of taking data from our handlers and sending it to Go templates.

Improved Routing & Middleware

One option for making our routes easier to manage.

Another option for making our routes simpler.

Middleware is useful, and easy to write.

State Management with Sessions

Saving our application state with a sessions package.

An overview of how sessions work.

Choosing a Project, and Working With Forms

An overview of what we will be working on.

Getting things started.

How to serve static site content using Go.

An overview of HTML pages.

Creating the landing page for our site.

Creating a few additional pages in HTML.

HTML forms, and how they work.

Making our form a bit more useful.

Creating the HTML page for a reservation.

Javascript & CSS

A brief overview of Javascript, and why it's so useful

Using a custom date picker instead of the built in browser functionality

Creating non-intrusive alerts for our web application using Notie

Making nice popup alerts using SweetAlert

How to simplify our Javascript by using modules

We simplify our alerts by wrapping them all in a Javascript module

Adding a custom popup function to our Javascript module

An overview of Cascading Style Sheets (CSS).

Coverting our HTML to Go Templates, and creating handlers

An overview of Go templates and how they work.

An overview of HTTP handlers, and how to make them.

How to return JSON as a response, instead of HTML.

What is Ajax, and how to we send/receive to an Ajax handler?

More about Ajax, and improving our implementation of it.

Reorganizing our code to make it a bit more sensible.

Starting the process of validating form submissions on the server.

More about validation.

Working on the reservation summary page.

An alternative to Go's built in template system

How to write unit tests and end-to-end tests

More about writing tests.

How to test our GET handlers.

Writing tests for POST handlers.

How to test our render package.

More about testing our render package.

Using Go's built in functionality check our test coverage.

Writing tests for our forms package.

The solution to the exercise.

Writing a shell script to make running our app simpler.
