Learn 11ty, Clojurescript and Dart

Dart is an object-oriented language you can use for building web applications, server-side code, and even mobile apps. It’s expressive, powerful, and has a friendly learning curve. 

In this course, we will look at the syntax and semantics of the Dart programming language. We will also cover various aspects of the Dart ecosystem, including its tools and packages that help make you a productive developer. This knowledge is applicable when developing software for client, server, and especially mobile with the Flutter framework. 

This course is beginner-friendly, but is well-suited for experience programmers as well. 

Dart is an open-source, scalable programming language, with robust libraries and runtimes, for building web, server, and mobile apps.

Get Started with Dart

Eleventy, or 11ty,  is a simple yet very powerful static site generator. It does not require any config to get started.

This what it will take you to get an 11ty project running.

```
npm install -g @11ty/eleventy
echo '# Page header' > README.md
eleventy
```

After watching this collection you will be able to:

* Bootstrap a simple 11ty website
* Use 11ty layouts
* Chaining multiple 11ty layouts
* Use 11ty Collections
* Create pages from data

...and much more

Eleventy was created to be a JavaScript alternative to Jekyll. It’s zero-config by default but has flexible configuration options. Eleventy works with your project’s existing directory structure.

Eleventy uses independent template engines. We don’t want to hold your content hostage. If you decide to use something else later, having your content decoupled in this way will make migration easier.

Getting Started with Eleventy

Learn how to make flexible customized Twitch Scenes using the static site generator Eleventy (11ty), CSS, and ComfyJS.

Throughout this course, you'll create scenes for preshow, host, and main desktop display streaming purposes. Using ComfyJS, we'll add embedded chat and be able to create responses to chat commands. Finally, we'll see how to actually setup the scenes in OBS to prepare to use them for your stream.

Bonus: you'll learn a bit more about CSS grid layout, and also the "cicada principle" to be able to show the commands randomly across the scene!

Develop Custom Twitch Scenes and Setup in OBS

Start from a blank project and build up to an Eleventy site that includes a blog collection and is prepared to source content from a headless CMS. You'll also learn how to add Sass as the styling solution, complete with triggering 11ty to re-compile when the Sass changes.

These lessons will help explain key 11ty features and concepts to help you make the most of this amazing static site generator.

By the last lesson, you'll have learned how to:
- define custom `input` and `output` directories
- create a layout that accesses front matter variables
- watch for Sass changes and include CSS in the build proces
- create an 11ty collection using `tags`
- define front matter for an entire collection
- make and apply a filter to a collection
- generate pages from an external data source, such as a CMS or API

Build An Eleventy (11ty) Site From Scratch

In this lesson, you will write a basic HTTP server in the Dart programming language. We will be using the HttpServer class from Dart's inbuilt 'dart:io' library to achieve this.

Dart is an object-oriented programming language by Google, which aims to help the developer build modern web applications. It covers client, server and now mobile with Flutter. It comes with a range of tools including a virtual machine, core libraries, and package management repository, lending enough ammunition to start your next project.

In this lesson, you will setup your first command-line Dart application. We will install the SDK and write our first program. This will form the basis for future lessons where we further explore the Dart ecosystem.

In this lesson, we will look at how to create variables and constants. These are containers that store data for later reference and/or retrieval.

In this lesson, we will cover Dart's inbuilt data types. Everything in Dart is an object, and therefore there are no primitive data types. In other words, all types extend a base type named Object. Any identifier without a value is set to null by default. There is no "undefined" value.

Understand Built-in types in Dart

Flutter allows you to build beautiful native apps on iOS and Android from a single codebase.

We will setup our first command-line Dart application. We will use the apt-get package manager on Ubuntu to install the SDK and write our first program. This will prepare you to follow along in the next lessons.

Set up your first Dart project on Linux

In this lesson, we will look at the different forms of creating parameters that are optional, namely positional and named. Optional positional arguments are useful when specifying a default value for a particular parameter. Optional named parameters are useful for specifying parameter defaults and writing self-documenting functions and methods.

Define Optional Named and Positional Parameters for Functions and Methods in Dart

In this lesson, we will look at various ways we can control the flow of our Dart code. Control flow statements allow us to break up the flow of code by employing decision-making, looping, branching and enabling our program to conditionally execute particular blocks of code. Dart adopts common control flow statements such as if/else, switch, while, do-while and for loops.

We will setup our first command-line Dart application. We will use the Chocolatey package manager to install the SDK and write our first  program. This will form the basis for future lessons.

Setup your first Dart project on Windows

We will look at how we can create classes and explore some various features. Dart adopts a single-inheritance model, meaning that you can only extend a single class. We will therefore extend our class example by creating an Employee subclass of a parent Person class.

ClojureScript is a compiler for Clojure that targets JavaScript. It emits JavaScript code which is compatible with the advanced compilation mode of the Google Closure optimizing compiler.

clojurescript

In this lesson I show you how to get and manipulate command-line arguments in Clojure/ClojureScript by writing a small program that greets you by name. I also show how comments are delimited, how to get a value out of a sequence, how to bind a symbol to a value, and how to define a function.

Handle command-line arguments in ClojureScript


In this lesson, we will cover Interfaces and Mixins. Interfaces act as a contract containing properties and methods that a class must define once it “implements” this interface. Mixins are Dart’s way of sharing properties and methods from multiple classes, since by design Dart adopts a single-inheritance model.

Define Interfaces and Share Class Members through Mixins in Dart

Futures represent a computation that does not complete immediately. Where a normal function returns a result, an asynchronous function returns a Future that will eventually contain the result. These are similar to Promises in JavaScript. In this lesson, we will learn how to program asynchronously by writing logic to capture values that are returned at a later time.

Capture and Return Asynchronous Values with Futures in Dart

Clojure is a dynamic, general-purpose programming language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language, yet remains completely dynamic – every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.

In this lesson I show what a Clojure keyword is and why we prefer them as keys in maps; and the three ways we can look up a value in a map.

In this lesson we’ll learn how to create an Android emulator in Android Studio & run a Flutter project on an Android Emulator.

Run a Flutter App on Android

In this lesson, we'll learn how to specify a configuration object containing all of the routes for our application & navigate between them in a Flutter application.

Navigation with Named Routes in Flutter

When creating a new Flutter application, you are given a simple templated Flutter project whose primary code lives in the main.dart file. In this lesson, we walk through this file & talk about what the boilerplate code is doing.

In this lesson we’ll learn how to style Text & Container widgets & also get a general understanding of how styling works in Flutter applications
