Learn 11ty, Ampt and Riot

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.

11ty

Our Twitch Scenes will use the static site generator Eleventy (11ty) to leverage templating features for creating the scenes. This lesson covers the base project which is available in the project repo under `/lessons/00-base`.

This lesson includes templating for the stream details and initial styling of the details section within the scene layout. The primary templating language in use is [Nunjucks](https://mozilla.github.io/nunjucks/templating.html).

Setup Eleventy Project for Creating Twitch Scenes

Riot brings custom tags to all modern browsers. Think React + Polymer but with enjoyable syntax and a small learning curve.

riot

It's easy to repeat over a collection and render many elements. Riot works very similar to Angular and has various syntaxes for it's each attribute. We'll look at the typical syntax for arrays, a shortened syntax, and an object key/value syntax.

Riot JS - Repeating Elements with Each Attribute

Riot takes a 'keep your styles close' approach with custom tags. You are encouraged to place your styles for a tags element right inline with the html and javascript. Learn how riot parses the inline styles as well as ways to keep your styles from bleeding out to the rest of your app. Scoped styles provide great isolation for your custom tag. Use the class attribute's special binding syntax to easily add and remove a class based on an expression.

Riot JS - Scoped CSS and Toggled Classes

Riot can listen for raw dom events on any element by adding the on* attribute to elements and referencing an event handler. Let's walk through a couple examples.

Riot JS - DOM Events

Every tag in Riot has a lifecycle. I'll explore the three hooks: mount, update, and unmount while adding an animation feature for an existing tag. Lifecycle hooks are important for setting up, tearing down, and keeping a tag's view up to date after external logic is run.

Riot JS - Tag Life Cycle Hooks

Tag Options allow you to abstract your custom tag elements into reusable objects by allowing the tag-user to specify the dynamic parameters of their component.

Riot JS - Tag Options

Getting started with Riot JS. We'll discuss riot's compile and mount process and build a small hello world component with simple data-binding.

Riot JS - Getting Started with this React-like micro-library

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

Gemini 2.0 has a context window of a million tokens, and this means that you can upload hundreds of files and allow it to inspect and analyze massive refactors across entire code bases. 

This lesson demonstrates concatenating an entire code base into a single file and then uploading it to AI Studio. Once within AI Studio, we ask it to find the types of tasks that it can evaluate for us. Then we select one of the tasks and ask it to generate instructions for that task. Once those instructions are complete, we then turn them over to Windsurf's Cascade agent, and we allow Windsurf's Cascade to do all of the work for us as we sit back, relax, and let the AI do our jobs.

Use Gemini 2.0 to Create Agent Instructions to Refactor an Entire Codebase

Learn how to display custom components in a [Tanstack Table cell](https://tanstack.com/table/latest/docs/guide/cells), including how to render capitalized text, apply conditional styling with class helper functions, and format dates using the `Intl` API for readable display. 

`flexRender` allows you to utilize the `cell` callback method in your column definitions. Tanstack table will call this function to render the custom component you defined.

Use tanstack table flexRender method to render custom components in a table component. Capitalize letters, apply conditional styling, and render dates with Intl

I'm extremely excited for the potential of AI watching your screen while you work. I decided to take Google's AI Studio for a spin, which just introduced a feature called "Stream Realtime", which allows AI Studio to observe your screen and listen to your microphone while you work.

This video is my initial attempt to try and coach AI Studio through the process of building a site from a reference site, essentially trying to build egghead.io from a Next.js starter template. And we'll explore the various attempts we make and what works and what doesn't.

[Shadcn](https://ui.shadcn.com/docs) is a popular component library that allows you to install components into your codebase.

Learn how to install the [Table component](https://ui.shadcn.com/docs/components/table) and use that presentational component with [Tanstack table](https://tanstack.com/table/latest).

Build a dynamic table component in React using shadcn component library and tanstack react table.

TypeScript's satisfies operator finally clicked for me when I realized it's almost always used for specific implementations of configuration objects. So this lesson walks you through the naive approaches I've taken before and how to solve them using the satisfies operator. After this, satisfies will be another tool in your belt in TypeScript. To clean up all the TypeScript code you have around configuration.

TypeScript's "satisfies" for Configuration

Windsurf and Cursor are both able to take an image and then use an agent to build out what it sees in that image. This lesson is going to compare Windsurf and Cursor by uploading the same image to both and giving them the same prompt. Comparing not only the results, but also the steps that they take to get there. We'll also try uploading additional images throughout the process to see what they do as far as revising along the way and improving the site as they go along. 

Windsurf Cascade vs. Cursor Composer Agent: Build a Site from an Image

In this lesson, you'll discover how to style View Transitions using CSS pseudo-selectors to create custom animation effects. We'll transform the default cross-fade into a smooth slide transition by targeting the ::view-transition-old and ::view-transition-new pseudo-elements. You'll learn how these powerful selectors give you precise control over your transition animations, allowing you to create more engaging and personalized user experiences with just a few lines of CSS.

Customize View Transitions with CSS Using view-transition-old and view-transition-new

In this lesson, you'll learn how to implement smooth state transitions in your web applications using the browser's built-in View Transitions API. We'll create a simple example that demonstrates how to animate between different text states with just a few lines of code - no external libraries required. This powerful native API makes it easy to add professional-looking transitions to your user interface, enhancing the user experience with minimal effort.

Create Smooth UI Transitions with the Native View Transitions API

I've been using Cursor for a very long time and their "Agent" feature in Composer is fairly new, so I'm still getting used to it. But since Windsurf recently got onto the stage with their Cascade agent, they've slowly been gaining the mind share on the UX for coding agents. I decided to put them to the test by putting Windsurf and Cursor on the exact same screen side by side trying to accomplish the same task and to see which workflow I would prefer. I've been a diehard Cursor user for over a year now, so it's going to take a lot for me to switch to a different IDE. But I just have to say, even from this simple demo, Windsurf is looking pretty nice.

This lesson is just going to walk through creating a CLI using both tools to print out inspirational quotes and to explore how they approach the step-by-step of installing packages and running commands and setting up all the files we need to get this running.

Windsurf Cascade vs. Cursor Composer Agent Side-by-Side Comparison

I've been using Cursor as my primary editor for over a year now, but recently I've heard wonderful things about Windsurf AI Agent features. I decided to record myself building out something I've always wanted to make, but never made the time for.

In this lesson, I demonstrate how to leverage Windsurf's powerful agent process to create a fun word-guessing game inspired by Heads Up. Watch as I build an interactive application featuring category selection and word navigation, complete with data hosting on GitHub Gists and deployment to GitHub Pages - all in under 30 minutes (before editing the lesson down to 12 minutes)!

What makes this project particularly exciting is how Windsurf eliminates the typical friction points of development. While this game was always on my project wishlist, the overhead of setup, configuration, and deployment made it hard to justify the time investment. Windsurf's agent process handles all these pain points seamlessly, from managing URLs to orchestrating deployment.

This lesson perfectly showcases how AI agents can help developers bring their backlog of project ideas to life, transforming what would typically be time-consuming tasks into efficient, enjoyable development experiences.
