Learn Css, Firebase and Github

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.

Now that we are on Fly.io we'll want to replicate the functionality that Vercel was automatically doing for us by creating and configuring a GitHub Action to deploy our site whenever new commits hit the main branch.

Luckily for us there are a number of pre-defined GitHub actions that we can utilize like `actions/checkout@v3`, `actions/setup-node@v3`, and `superfly/flyctl-actions/setup-flyctl@master`. You'll notice that the first two actions are maintained by GitHub where the last is maintained by Fly.io. 

During this process you will also need to generate a token to verify your deployment to Fly.io and store that in the repository Action secrets.

Firebase Intro

Next.js is a minimalistic framework for server-rendered React applications.

First thing we'll do is navigate to [Github's Developer Settings](https://github.com/settings/applications/new) to register a new OAuth application.

Here we will set the app name, url, and callback url both for the development environment.

We will copy the Client ID and generate secrets and set them in our `.env`.

Finally we'll generate a `NEXTAUTH_SECRET` with the `openssl` cli tool to generate a random, secure string.

Set up GitHub OAuth for a Next.js 13 Application

Supabase is an open source Firebase alternative. A service to:

- Listen to database changes.
- Query your tables, including filtering, pagination, and deeply nested relationships (like GraphQL).
- Create, update, and delete rows.
- Manage your users and their permissions.
- Interact with your database using a simple UI.

Supabase is not a 1-to-1 mapping of Firebase. Most notably, Supabase uses Postgres rather than a NoSQL store.

[Supabase](https://supabase.com) includes multiple authentication strategies. In this lesson, we create a Supabase client to trigger the OAuth authentication flow with GitHub.

Additionally, we discuss the differences between Client and Server Components in the [Next.js App Router](https://nextjs.org/docs/app):

- Client Components: user interactivity
- Server Components: data fetching

Lastly, we create a Route Handler to exchange an authentication code from GitHub for their Supabase session.

## Code Snippets

**Authenticate with GitHub OAuth**

```tsx
await supabase.auth.signInWithOAuth({
  provider: "github",
  options: {
    redirectTo: "http://localhost:3000/auth/callback",
  },
});
```

**Exchange code for Supabase session**

```tsx
await supabase.auth.exchangeCodeForSession(code);
```

Authenticate Users with GitHub OAuth using Supabase and Next.js Client Components

[Supabase](https://supabase.com/) includes many ways to authenticate users - Email and password, magic link, mobile OTP etc. In this lesson we implement social login with GitHub by registering a new OAuth Application and providing Supabase with the Client ID and Secret.

Get started building web applications with Angular and Firebase.

In this course, you'll learn how to set up and use Firebase in your Angular applications using the AngularFire library.

We choose the AngularFire library because it is an official library created by the Firebase and Angular teams to work better with Angular.

It helps you by wrapping everything into observables and helps update zones. 

By the end of this course, you'll be able to build web applications using Cloud Firestore as your database, Firebase Authentication as your Auth system, Cloud Storage to save files, and Firebase Hosting to deploy your applications to the web.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

Build Full Stack Web Applications with Angular and Firebase

The last step we'll take is to make our application public.

We'll use the Angular CLI to generate a production build of our application, and then we'll use the Firebase CLI to deploy our application to Firebase hosting servers.

Firebase hosting is a great choice for us because Firebase Hosting will incorporate the services that we use in the app by default.


Deploy an Angular Web Application Powered by Firebase to Firebase Hosting

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

We want to secure our file storage so not just anyone can upload files to our Cloud Firestore.

We'll go through Cloud Storage Security rules to add rules and restrictions to our bucket server-side. You'll notice that the default rules for storage are the same as the database in that they are open to anyone for 30 days.

There are a few restrictions that we will implement:
    - Only allowing authenticated users to upload files.
    - Restrict the size of the files we want to upload.
    - Restrict the type of files we want to upload. (__i.e: only accept images or pdfs__)


Restrict File Uploading to Firebase Cloud Firestore with Cloud Storage Security Rules

Users can now see that files are attached to tasks but they can't do much with that. We need to let users be able to download the files so we'll do that in this lesson. 

We'll create a button for users to download the files they have in their tasks. We take a JavaScript first approach here by creating an anchor tag and adding all of the properties we need to allow for a download.


Download Files from Firebase Cloud Storage in Angular

Ionic is the beautiful, free and open source mobile SDK for developing native and progressive web apps with ease.

Now that file uploading works, we want to actually show that a task has files associated with it. To do this we will need to update the task object with a file property that we'll push files too.

In this lesson, we'll use Cloud Storage methods like getDownloadUrl() to get the file's download URL from our bucket.

Then we'll add that file's information to our task and persist it in the database to show the list of files in a task to the user.

While we do this, you'll see how we can easily add a spinner when files are being uploaded using Ionic loadingController.


Save and Display Tasks Files Utilizing Firebase Cloud Storage getDownloadUrl

We want our users to have more power by uploading and downloading files to the tasks they create.

In this lesson, we'll start creating the functionality that will allow our users to upload files. I went ahead and created the UI and click handler for this feature so we can focus on the actual file uploading.

We'll use the browser's `<input type="file">` to select files from our device and then we'll use Cloud Storage methods to upload the file to our storage bucket.


Upload Files to Firebase Cloud Storage with AngularFire storage uploadBytes

Our Security Rules are getting repetitive with all the logic that we've copy and pasted for the several actions we currently have.

In this lesson, we'll go through our security rules and extract the duplicated rules into functions that we can call.

With this approach, we can eliminate the copy/pasting and make our functions a bit more readable.


Refactor Firebase Security Rules to Use Functions for Easier Reading

Currently our Firebase Security Rules aren't as secure as they could be. When it comes to tasks, we are comparing the request's user on the task to the requests auth id. If someone intercepted this request and changed the ids here they could get away with it.

In this lesson, we'll go through our security rules and create a different set of security rules depending on the action the user is performing. For tasks specifically we will check the documents user id against the request user id.

We'll take things a step further as well and write different rules if a user is trying to create, delete, or update a task document.


Break Up Firebase Security Rules Into Different Actions Depending on Operation Performed

All the security we've added to our application has been client side. In a production app this isn't enough, we want to add security to our database directly.

We'll start securing our application's database with Firestore Security Rules.

We'll write security rules to prevent unauthenticated users from accessing our database, and then we'll add extra rules so that only a document's owner can access that document.


Secure your Firestore Data with Security Rules

Now that tasks are actually associated with a user in our database, we want to only show a user their own tasks.

To do this we'll revisit our task list and make some changes to use the `query()` and `where()` methods to filter our list before we get it from the database.

We'll learn how to pass our user's ID to a query and fetch only the tasks that belong to that user. Because Firebase uses Observables, you'll also see how we handle and change observables in Angular.


Query and Filter Documents from Firestore by userId with query()

Now that we have users in our application, we need to start associating them with tasks that are created. We'll revisit our task object and add our currently logged-in user's ID to our task object so that we can show users only their tasks. This is done through the Firebase Auth module.

Store the User's ID in the Task Documents That are Saved in Firestore

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.

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.

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 🔥

Effective Runtime Type Checks with Zod


Cursor can now automatically run commands in the terminal and walk step-by-step towards building out your entire project. You give it a goal, then it will suggest the commands you need to run and the files that you need to create and you can work with it to achieve what you're building. This lesson does a quick walkthough of using a Cursor Agent to build a project from scratch and guide it along the way. Cursor Agents definitely feel like a sneak peek at the future of programming!
