The title says it all, we install Go and set up Visual Studio Code as an integrated development environment (IDE).

TL;DR;

Use the accompanying course overview as PDF. It is part of the the course.

Support by the package managment in Go

Channels are the lifeblood of Go communication, without them things would flow less smooth-lee.

A simple example just to make sure you know what we do this for.

Often criminally neglected, but no less important, is to test the code!

Brief explanation, where our application will live on the HTTP request/response cycle

Our very first web application comes to life!

We add another handler and equip it with the power of internal functions.

Learn how to handle errors gracefully.

We structure our code and make it ready to be be used with go modules!

Learn to use layouts to get everything out of your templates.

Learn a method to build a simple dynamically growing cache.

A static cache for templates offers advantages for our web application.

We use a global variable that we make available in a configuration file.

We use the global variable defined in the configuration file to create a static cache that can be turned on and off.

Notes on the use of a configuration file.

A brief note of why to use github.com may be a good idea!

Including static files in web applications is about including static files like CSS, JavaScript, and images.

How old and modern HTML works.

We set up a serverless development environment to create HTML pages that we will later convert into Go templates. We start with the landing page.

With a simple landing page, bungalow pages are 1-2-3-Finished!

Creation of an HTML page with a form to get dates from the user.

An HTML form to make a reservation.

Learn how to turn plain HTML into GO templates.

We provide security against Cross-Site Request Forgery (CSRF) by generating a token for each potential POST request using the middleware NoSurf.

Explore how to use Golang to create a handler that returns data in JSON format.

In this lesson, you will learn how a request via JavaScript to our web application can trigger a response from our JSON data providing handler, interpret its response, and use the data in JavaScript!

In addition, you will learn to customize the custom() function in JavaScript to make it more generic.

Keep your code’s structure clean – do refactoring.

A small overview of what server-side validation is and why it makes more sense than client-side validation (alone) in many cases.

Evaluate form data and identify errors.
