Learn Aphrodite, Nuxt and Script-kit

How often do you avoid scripting something because it takes too much effort?\n\nScript Kit makes it easy to create and run scripts that solve your daily problems. Create a new script from the prompt then your script opens in the editor of your choice. Write a few lines of JavaScript. Then run the script from the prompt.\n\nSimply put, Script Kit helps you script away the friction of your day.

Create, read, update, delete. Four actions that every developer becomes intimately familiar with over their career. Script Kit aims to make this process as pleasant as possible using a `db` helper and what better way to show it off than a Todos app?

You will also learn how to create and switch between tabs through Script Kit's `onTab` and `setTab` methods. 

[Install todos](https://scriptkit.com/api/new?name=todos&url=https://gist.githubusercontent.com/johnlindquist/3bdc967ffbd2f6d72491d07bf720f7e2/raw/a37b0058b502d6ba4bebd7a31a30be8789f5a146/todos.js")

```js
// Name: Todos

import "@johnlindquist/kit"

let { todos, write } = await db({ todos: [] })

onTab("Todos", async () => {
  while (true) {
    let todo = await arg("Toggle todo:", todos)
    let t = _.find(todos, todo)
    t.tag = t.tag === "open" ? "done" : "open"
    await write()
  }
})

onTab("New", async () => {
  let name = await arg("New todo:")
  todos.push({ name, id: uuid(), tag: "open" })
  await write()
  setTab("Todos")
})

onTab("Remove", async () => {
  let todo = await arg("Remove todo:", todos)
  _.remove(todos, todo)
  await write()
  setTab("Todos")
})
```

When you want to collect news sources, airline ticket prices, or any events from sites that don't offer APIs, you can use scrapers to grab elements from off the page. 

Script Kit includes a `scrapeSelector()` helper that takes the URL you want to scrape and the selector you want from the page. Using the `// Schedule` metadata, you can also have this script run in the background on a Chron schedule and collect the data for you.


[Install scrape-tech-news](https://scriptkit.com/api/new?name=scrape-tech-news&url=https://gist.githubusercontent.com/johnlindquist/acd397a2ed487ef2a06c00d2951bed63/raw/3942107d2c92abc2c0317d15b0b3d025c5643ef0/scrape-tech-news.js")

```js
// Name: Scrape Tech News
// Schedule: 0 11 * * *

import "@johnlindquist/kit"

let h3s = await scrapeSelector(
  "https://news.google.com/topics/CAAqJggKIiBDQkFTRWdvSUwyMHZNRGRqTVhZU0FtVnVHZ0pWVXlnQVAB?hl=en-US&gl=US&ceid=US%3Aen",
  "h3"
)

let filePath = home("tech.md")
await ensureFile(filePath)
let contents =
  `

## ${new Date()}

` + h3s.map(h3 => `### ${h3}`).join("\n")
await appendFile(filePath, contents)
```

We put a lot of work into browsing the internet every day, it would be a pity to lose it all by closing all of our tabs. 

Script Kit can collect all of the tabs you currently have open in Chrome using its `getTabs` method and store them anywhere you want. 

This particular script converts the tabs to markdown links and stores them in a text file on your file system, but you could convert and store them using any approach you can think of.


[Install save-tabs](https://scriptkit.com/api/new?name=save-tabs&url=https://gist.githubusercontent.com/johnlindquist/4713a161a9ec48932b05436ba6a1a123/raw/33f753586d1a158dfb69d07f29850b6013d59f8b/save-tabs.js")

```js
// Name: Save Tabs

import "@johnlindquist/kit"

let tabs = await getTabs()

let tabsMd = tabs
  .map(tab => `* [${tab.title || tab.url}](${tab.url})`)
  .join("\n")

let notes = await editor(tabsMd)

let filePath = home("tab-notes.md")
await ensureFile(filePath)
await appendFile(filePath, notes)

edit(filePath)
```

Sometimes you just want to select and modify some text you have written somewhere on your system. To help you with this, Script Kit provides a `getSelectedText` and `setSelectedText`. Between these two helpers, your script and use and/or modify the text however you want. 

Applying an npm tool like `title-case` can help when you're not entirely sure when certain words need to be capitalized. In fact, I used the title case script on the title of this lesson!

[Install title-case](https://scriptkit.com/api/new?name=title-case&url=https://gist.githubusercontent.com/johnlindquist/0f8323d6aa599cfd62034351f9d38e8c/raw/625d0afd57ccbf8bf64c62bd135474cecf98c58b/title-case.js")

```js
// Name: Title Case

import "@johnlindquist/kit"

let { titleCase } = await npm("title-case")

let selectedText = await getSelectedText()
let titleText = titleCase(selectedText)

await setSelectedText(titleText)

// This Is the Title of My Next Blog Post
```


Apply Title Case to Text Anywhere Using Script Kit

Developers often keep their dev projects in a specific directory like "dev", "projects", or something similar. Script Kit allows you quickly read all the files of any directory then display them in a list so you can open them in your editor.


[Install open-project](https://scriptkit.com/api/new?name=open-project&url=https://gist.githubusercontent.com/johnlindquist/91cf994e450ecd5d45bce9aef9b345a1/raw/880be2d827b9602afe59d4e230e6753288f5bbb8/open-project.js")

```js
// Name: Open Project

import "@johnlindquist/kit"

let dirs = await readdir(home("dev"))

let selectedDir = await arg(
  "Open Project:",
  dirs.map(dir => ({
    name: dir,
    description: home("dev", dir),
    value: home("dev", dir),
  }))
)

edit(selectedDir)
```

We all have various tasks we need to accomplish with images. Whether it's resizing, optimizing, organizing, uploading, or anything else. Script Kit provides a `drop` component so you can simply drag and drop images into a script and process them in whatever way matches your workflow.


[Open drop-image in Script Kit](https://scriptkit.com/api/new?name=drop-image&url=https://gist.githubusercontent.com/johnlindquist/fe5b06f81cfea0d2dd94f743bc40ed15/raw/40a1b6ab271f7f664d7e54c4b779b056c6195b1c/drop-image.js")

```js
// Name: Drop Image

import "@johnlindquist/kit"

let files = await drop()
let imagePath = files[0].path

let Jimp = await npm("jimp")

let image = await Jimp.read(imagePath)
let newImagePath = path.resolve(
  path.dirname(imagePath),
  `new-${path.basename(imagePath)}`
)
await image
  .resize(parseInt(await arg("Width:"), 10), 100)
  .write(newImagePath)

```

Chrome allows developers to execute JavaScript using Apple Events. When you enable this feature, you can write scripts that can access and modify the page you're currently browsing. 

You can get the site's contents, update storage, or do any action you would typically do through an extension of the Chrome Dev Tools.

```jsx
let value = await applescript(`
tell application "Google Chrome" to tell window 1
	get execute active tab javascript "

${js}

"
end tell
`)
```

Control Chrome From Script Kit using Apple Events

Many developers use Chrome's Dev Tools as a playground for testing out data and JavaScript features. Script Kit enables you to launch Chrome Dev Tools instantly by simply using the `dev` method. Any data you pass into `dev` will show up in the console so you can inspect and play with the data in any way that you want.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

In this video you'll learn how to use Amplify hosting to deploy a Nuxt site from a Git repository. We'll begin by walking through the steps of creating the deployment and configuring the correct build settings to enable a static build. Once the site is deployed, we'll view the live site hosted on AWS.

Deploying a Nuxt Site to AWS from a Git repository with Amplify hosting

In this video you'll learn how to deploy a static Nuxt site to AWS's global edge CDN in less than two minutes. We'll start from scratch, creating a new Nuxt site using npx and walk through the build configuration to set up the deployment target for Jamstack / static site hosting. From there, we'll initialize a new Amplify project using the Amplify CLI and walk through the settings to configure the proper build command for Amplify hosting. Finally, we'll deploy and view the live site. Once we're finished, we'll delete the project and the hosting service.

URLs often reflect some bit of data that the page should load. This lesson walks you through adding a custom URL Param to the router then forwarding that Param to load data onto the page.

Load Data from URL Params in Vue.js and Nuxt.js

As you create more and more routes, the paths become difficult to manage and concatenate the parts together as just a giant string. Using named routes allows you to reference the route by a simple string then pass in the params as an object. This lesson covers configuring named routes in Nuxt.js in the `nuxt.config.js` and the passing the named route to a `router-link`.

Configure Named Routes in Vue.js and Nuxt.js

Sometimes the `pages/` directory structure doesn't meet your needs, so you'll need to customize your routes manually. Using the nuxt config and "hidden pages" you can map routes to view components without getting in the way of the default pages routing.

Add Custom Routes for Hidden Pages with Vue.js and Nuxt.js

Nuxt.js allows you to return a `Promise` from your `data` function so that you can asynchronously resolve data before displaying the page. This allows the server to fetch the data and render the page once it's ready.

Preload Data using Promises with Vue.js and Nuxt.js

Nuxt.js enables you to easily create layout and navigation by replacing the default App.vue template with your own `app.vue` layout in a `layouts` directory. Then you simply surround your content (the `<nuxt>` instance) with your navigation and/or layout and you're ready to go.

Create Vue.js Layout and Navigation with Nuxt.js

The vue-cli allows you to easily start up Vue projects from the command line while Nuxt.js enables a page-based routing system that follows your file structure. Combine these two projects and you'll have a Vue app created from scratch deployed in a matter of minutes.

Scripting can save you a _ton_ of time by automating your daily workflows.

But it's hard to justify the time investment of learning Bash to write your scripts.

Bash is the great barrier we all face when trying to script away our daily tasks. There are some common problems that we run into when dealing with it. Like what if we want to display images? Or share our script with other devs _cross platform_? 

You know what you want your script to do. You know you could figure it out if you had the time. But it's all just too darn much.

What if you could write your scripts in JavaScript, launch a GUI, and were actually *easy* to share with your team? **audible gasp**

Script Kit is the tool that’s been missing from your developer toolbox for so, so long. 🛠

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.

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 🔥
