Learn 11ty, Css and Prisma

Bootstrap is an incredibly popular CSS framework designed to make your website look great on mobile and desktop.

By the end of this course, you'll be familiar with many of the popular classes and components that Bootstrap uses to apply in your own projects.

For each feature you build in the course, you'll get a sense for what the relevant classes do for those components and links to documentation for further exploration.

For the course demo application, we will analyze the landing pages of Microsoft and Apple to identify common components that are implemented. When these are identified, you'll implement these components yourself with Bootstrap.

You'll build several common UI elements such as a nav bar, a carousel of images, Cards, and Forms.

Through building these components, you'll understand what is behind the different classes Bootstrap gives you and get familiar with how it exposes flex and grid layout for you.

Cascading Style Sheets bring order and beauty to our applications.

Prisma is a next-generation open-source ORM For Node.js and TypeScript that helps developers build faster and make fewer errors.

It supports the following databases: PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, and more recently, MongoDB (Preview).

Prisma provides a complete toolkit:

- Prisma Client: Auto-generated and type-safe database client
- Prisma Migrate: Declarative data modeling and customizable migrations
- Prisma Studio: Modern UI to view and edit data

Next up is creating a Planetscale database for our application. Planetscale works a lot like GitHub in that it uses branches for development and production.

We will create a new database and then create a dev branch to separate the data we create in dev from what is in production.

When the database is created, we'll set the `DATABASE_URL` in our `.env` file for the main and dev branches.

The last thing we will need to do is push the prisma schema to planetscale so that it can create the necessary tables for our application to function. 

Explore the prisma schema and tables created to get more familiar with what the application is doing.

Set up Planetscale Main and Dev Branches and Create Tables through Prisma

Now that we have a project, we need a Pin input to work with. We'll create 4 inputs and style them so they look like a security code pin input that you would expect to see.

Style a Pin Input through Data Attributes in React

Prisma is an open-source ORM. It consists of the following parts: 

- Prisma Client: Auto-generated and type-safe query builder
- Prisma Migrate: Migration system
- Prisma Studio: GUI to view and edit data in your database

Prisma Client can be used in any Node.js or TypeScript backend application (including serverless applications and microservices). This can be a REST API, a GraphQL API, a gRPC API, or anything else that needs a database.

In this course, you will learn how to initialize Prisma in a TypeScript Node project, use Prisma Client to create and find records, use Express to create data dynamically, and more! 



Build a Backend with Prisma in a TypeScript Node Project

Prisma Client allows us to limit the amount of data that is returned from queries. It also allows us to be specific about which data should be included in the returned dataset. In this lesson, we use the select and include operators to be specific about the shape of our returned data.

Limit the Amount of Returned Data with Prisma Client

Prisma Client has a specific API for relating data from one table to another when creating new records. In this lesson, we use the connect operator to establish a link between two tables as new records are created.

Use Prisma Client to Connect Related Tables when Creating New Data

When two tables are related to one another, we can use Prisma Client to query for data through those relations. In this lesson, we see how to use Prisma Client to tie together data from two separate tables and pull it out in a nested fashion.

Use Prisma Client to Query for Related Data

Prisma Schema Language is used to model our database tables and establish relations between them. Prisma offers autocompletion to register the relations. In this lesson, we create a new model for a second database table and see how to relate our two tables together.

Create a Relation Between Two Tables in the Prisma Schema

Prisma is API-agnostic meaning that it doesn't matter how we build our APIs. They can be REST APIs, GraphQL APIs, or anything else. In this lesson, we see how to use express to accept JSON data to be forwarded off to Prisma to create new records in the database.

Use Express to Create Data Dynamically

Prisma Client offers methods to create new database records. These methods accept a data object and return the result to be consumed by clients. In this lesson, we use Prisma Client's create method to create new records in the database.

Create a Database Record with Prisma Client

Prisma Client has a full API for selecting subsets of data in our tables. We can use the WHERE clause to match specific conditions for which we would like to return data. In this lesson, we look at how to use the WHERE and its operators to return a subset of data.

Use Prima Client to Select a Subset of Data

Prisma Client is a fully type-safe database access client that is automatically generated based on our Prisma Schema files. In this lesson, we use Prisma Client to access records in our database programmatically. We show how to return the data from an endpoint built with express.

Use Prisma Client to Find Many Records in a Table

Prisma Studio is a GUI for viewing and interacting with our databases. In this lesson, we view our database with Prisma Studio and use it to create our first record.

Use Prisma Studio to Create a Record

Prisma offers a powerful database modeling language called the Prisma Schema Language. It allows us to describe the shape of our tables, the columns they should have (and their types), and relations between tables. In this lesson, we get started with our first table in our Prisma Schema file.

Create a Model for a Table and Run Migrations

The Prisma CLI comes with commands to initialize Prisma in a project, run migrations, generate Prisma Client and more. In this lesson, we install the relevant dependencies and initialize Prisma in a TypeScript Node project.

Initialize Prisma in a TypeScript Node Project

Prisma offers an extension for VS Code that enables syntax highlighting, autocompletion, and more for Prisma Schema files. In this lesson, we learn how to install the Prisma VS Code extension.

We'll discuss the minimum set of files that are required to get up and running with Vue.

We'll add an `index.html` file as our entry point, a `main.js` file that will contain our JavaScript code and a `styles.css` that will contain all of our CSS. We also load Vue into our project with UNPKG which exposes the Vue object to us.

Set up the Minimum Files Needed to Run Vue 3

Using the open-source project ComfyJS, display a response to chat commands overlaid on the Twitch scenes. We'll use Eleventy templating to create a partial holding the initial command HTML. Then, using [the cicada principle](https://lea.verou.me/2020/07/the-cicada-principle-revisited-with-css-variables/), we'll enable visuals of each command word to appear in a seemingly random order across the scene. We'll use the `ComfyJS.onCommand` method to enable cloning the command template nodes and adding them as the commands are triggered through Twitch chat. CSS transitions will be used to apply a fade and zoom in/out effect for the added command nodes.

Respond to Twitch Chat Commands With Scene Elements and ComfyJS

To embed Twitch chat, we'll use the open-source project [ComfyJS](https://github.com/instafluff/ComfyJS) which is a JavaScript API to interface with the Twitch API. It offers features like responding to incoming chat messages and chat commands and other events like new subscriptions.

Using ComfyJS, we'll set up a section in the Twitch scenes to show incoming chat messages. This lesson covers the CSS needed to style the chat messages and make older ones scroll out of view once new ones are received. We'll take advantage of Eleventy templating to include the necessary scripts.

Embed Twitch Chat in Scenes Using ComfyJS

Add three Twitch scenes for preshow, host, and main, and style them using CSS. Learn how to include transparent background areas with CSS gradients that will mask capture areas for a webcam and desktop display.

Create Twitch Scene Templates and Style

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


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

This lesson will show you 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).


Create a Table Component with Shadcn and Tanstack Table

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

This TypeScript tutorial explains how to use generics, allowing for different types to be passed as arguments. It discusses the use of shorthand syntax in generics and illustrates with examples. This method is useful for library creation, providing type safety and control to the user.

```typescript
interface PhotoMetadata<T> {
  title: string;
  takenAt: Date;
  customData: T;
}

// Function that processes a photo with custom metadata
function processPhoto<T>(photo: PhotoMetadata<T>): {
  processedTitle: string;
  daysSinceCapture: number;
  customDataSummary: T;
} {
  const today = new Date();
  const daysSinceCapture = Math.floor(
    (today.getTime() - photo.takenAt.getTime()) / (1000 * 60 * 60 * 24)
  );

  return {
    processedTitle: photo.title.toUpperCase(),
    daysSinceCapture,
    customDataSummary: photo.customData
  };
}

// Example usage with different custom data shapes
type CameraSettings = {
  iso: number;
  aperture: string;
  shutterSpeed: string;
}

type LocationData = {
  latitude: number;
  longitude: number;
  locationName: string;
}

// Using with camera settings
const photoWithCamera: PhotoMetadata<CameraSettings> = {
  title: "Sunset at beach",
  takenAt: new Date('2024-01-15'),
  customData: {
    iso: 100,
    aperture: "f/2.8",
    shutterSpeed: "1/1000"
  }
};

// Using with location data
const photoWithLocation: PhotoMetadata<LocationData> = {
  title: "Mountain vista",
  takenAt: new Date('2024-02-01'),
  customData: {
    latitude: 45.5231,
    longitude: -122.6765,
    locationName: "Mount Hood"
  }
};

const processedCameraPhoto = processPhoto(photoWithCamera);
const processedLocationPhoto = processPhoto(photoWithLocation);

processedCameraPhoto.customDataSummary.iso
processedLocationPhoto.customDataSummary.longitude

```

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.

Build a Word Game with Windsurf's Cascade AI Agent



Discover how to harness the power of Cursor IDE's Composer Agent feature to optimize your code. In this lesson, you'll witness an AI agent doing all the work to generate test suites, implement performance benchmarks, and create optimized function variations - all without writing a single line of code. You'll learn how to validate performance improvements through data-driven benchmarking, ensuring that optimizations are backed by concrete metrics rather than speculation. This hands-on demonstration showcases a groundbreaking approach to automated function development that combines the precision of test-driven development with the efficiency of AI-powered optimization.


Agent-Driven Development in Cursor: Testing, Benchmarking, and Optimizing Functions

This course is aimed for using `zod` effectively in projects based on TypeScript (both browser and node.js). The benefits you gain with this course is not just simply coding, but also understanding when/why/how should you perform runtime validation.

`zod` is the missing piece to TypeScript's capabilities, which can guarantee type-safety only in compile-time.

`zod` can be used whenever the compiler cannot guarantee what happens in runtime. And... it's a very frequent usecase, such as HTTP calls, websockets, etc.

In this course you get quickly up and running by:
1. using `zod` with primitives and objects
2. adapting `zod` quickly to existing projects thanks to automatic generators
3. changing the strategy frm type-first to schema-first
4. using error-throwing `parse` or non-error-throwing `safeParse` basing on your needs
5. applying `zod` to the most common usecase - validating API responses
6. handling errors the most convenient way (out of many!)

Take advantage of runtime validation with `zod`. Take advantage of the detailed lessons in this course 🔥
