Tailwind is a utility-first CSS framework for rapidly building custom user interfaces.

tailwind

[Tailwind](https://tailwindcss.com/) is an atomic CSS framework that makes styling an application more consistent and maintainable. In this lesson, we look at building out a similar UI to Twitter using only Tailwind classes.

Additionally, we use a heart icon from Feather Icons for our like button, and create a new `<GitHubButton />` component that displays a nicely styled GitHub logo to trigger the user authentication flow.

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

[Supabase](https://supabase.com/) allows us to subscribe to changes in the database, and update our UI, without the user needing to refresh the page. In this lesson, we create a subscription for `postgres_changes`, listening for any change events - insert, update or delete - on our tweets table.

Additionally, we call the `router.refresh()` function to re-run our Server Components, fetching fresh data from Supabase.

## Code Snippets

**Subscribe to database changes**

```tsx
const channel = supabase
  .channel("realtime tweets")
  .on(
    "postgres_changes",
    {
      event: "*",
      schema: "public",
      table: "tweets",
    },
    (payload) => {
      router.refresh();
    }
  )
  .subscribe();
```

Dynamically Update UI with Database Changes using Supabase Realtime

"Optimistic UI" is a pattern for updating the page immediately with the data you have available, rather than waiting for the database query to resolve. In this lesson, we use React's `useOptimistic` hook to create an array of tweets that we can instantly update with our new state, when the user clicks the like button.

## Code Snippets

**Call useOptimistic hook**

```tsx
const [optimisticState, addOptimisticState] = useOptimistic(
  initialState,
  (currentState, newState) => {
    // merge state
    // return new state
  }
);
```

**Add optimistic tweet**

```tsx
addOptimisticTweet({
  ...tweet,
  likes: tweet.likes - 1,
  user_has_liked_tweet: !tweet.user_has_liked_tweet,
});
```

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

[TypeScript](https://www.typescriptlang.org/) reduces runtime errors and makes code more maintainable. In this lesson, we use the [Supabase](https://supabase.com/) CLI to introspect our PostgreSQL schema and generate TypeScript definitions.

Additionally, we resolve a collection of TypeScript errors and create a custom union type for our transformed tweets - making it globally available throughout our Next.js application.

## Code Snippets

**Custom type for TweetWithAuthor**

```tsx
type TweetWithAuthor = Tweet & {
  author: Profile;
  likes: number;
  user_has_liked_tweet: boolean;
};
```

**Generate TypeScript definitions**

```bash
npx supabase gen types typescript --project-id your-project-id > lib/database.types.ts
```

Declare Global Intersection Types for Transformed Supabase Data with Typescript

In this lesson, we create a new component to display the likes from [Supabase](https://supabase.com/). This component will be interactive so it needs to be a Client Component.

Additionally, we extend our Supabase query for `tweets`, and join the columns from our `likes` table.

Lastly, we make this button dynamic by checking whether the user has previously liked this tweet. If they have not, we increment the likes by 1, otherwise, we decrement them by 1.

## Code Snippets

**Querying data across tables**

```tsx
const { data } = await supabase
  .from("tweets")
  .select("*, profiles(*), likes(*)");
```

PostgreSQL is a powerful, open source object-relational database system.

postgres

We create a PostgreSQL join table for `likes` in the [Supabase](https://supabase.com) dashboard. This has a many-to-many relationship between the `profiles` and `tweets` table, allowing us to store each instance of a like between a user and a tweet.

Additionally, we create Row Level Security (RLS) polices to enable `select`, `insert` and `delete`.

## Code Snippets

**Create likes table**

```sql
create table public.likes (
  id uuid default gen_random_uuid() primary key,
  created_at timestamp with time zone default timezone('utc'::text, now()) not null,
  user_id uuid references public.profiles on delete cascade not null,
  tweet_id uuid references public.tweets on delete cascade not null
);
```

**Enable Row Level Security**

```sql
alter table public.likes enable row level security;
```

**Enable insert action with RLS policy**

```sql
create policy "authenticated users can insert their own likes" ON "public"."likes"
as permissive for select
to authenticated
using (user_id = auth.uid());
```

**Enable delete action with RLS policy**

```sql
create policy "authenticated users can delete their own likes" ON "public"."likes"
as permissive for delete
to authenticated
using (user_id = auth.uid());
```

**Enable select action with RLS policy**

```sql
create policy "authenticated users can select likes" ON "public"."likes"
as permissive for select
to authenticated
using (true);
```

[Server Actions](https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions) are a way to perform server-side mutations in the [Next.js App Router](https://nextjs.org/docs/app). In this lesson, we create a `<NewTweet />` component that renders a form for the user to enter a new tweet. This form is submitted to a Server Action, which writes this data to [Supabase](https://supabase.com/).

Additionally, we create a Server Action Supabase client and call the `getUser` function to fetch the currently signed in user.

Lastly, we write a Row Level Security (RLS) policy to enable the `insert` action for `authenticated` users.

## Code Snippets

**Posting form to Server Action**

```tsx
export default function NewTweet() {
  const addTweet = async () => {
    "use server";
  };

  return <form action={addTweet}>...</form>;
}
```

**Create Supabase client in Server Action**

```tsx
const supabase = createServerActionClient<Database>({ cookies });
```

**Get user from Supabase client**

```tsx
const {
  data: { user },
} = await supabase.auth.getUser();
```

**Insert tweet with Supabase**

```tsx
await supabase.from("tweets").insert({...});
```

Run Authenticated Server-side Mutations with Next.js Server Actions

[Supabase](https://supabase.com/) has an `auth.users` table that contains information about our user and their session. We want to display the user's name, username and avatar alongside their tweets, but the `auth.users` table cannot be publicly accessible, as it contains sensitive information.

In this lesson, we create a new table called `profiles` and populate it with the data we want to display from the `auth.users` table. Additionally, we set up a PostgreSQL Function and Trigger to create a new profile for any user added to the `auth.users` table.

Lastly, we create an RLS policy for the `profiles` table to enable read access, and re-generate our TypeScript definitions file to contain our new table.

## Code Snippets

**Create profiles table**

```sql
create table public.profiles (
  id uuid not null references auth.users on delete cascade primary key,
  name text not null,
  username text not null,
  avatar_url text not null
);
```

**Enable Row Level Security**

```sql
alter table public.profiles enable row level security;
```

**Enable read access with RLS policy**

```sql
create policy "anyone can select profiles" ON "public"."profiles"
as permissive for select
to public
using (true);
```

**Create PostgreSQL Function to create profile**

```sql
create function public.create_profile_for_user()
returns trigger
language plpgsql
security definer set search_path = public
as $$
begin
  insert into public.profiles (id, name, username, avatar_url)
  values (
    new.id,
    new.raw_user_meta_data->'name',
    new.raw_user_meta_data->'user_name',
    new.raw_user_meta_data->'avatar_url'
  );
  return new;
end;
$$;
```

**Create PostgreSQL Trigger to create profile**

```sql
create trigger on_auth_user_created
  after insert on auth.users
  for each row execute procedure public.create_profile_for_user();
```

Automatically Generate a Profile for Every User with PostgreSQL Function Triggers

[Supabase](https://supabase.com/) uses the `auth.users` table to store information about our users and their sessions. In this lesson, we add a column to the `tweets` table to associate each tweet with one of our users.

Additionally, we set up cascading deletes, so when a user is deleted from the `auth.users` table, their tweets are also deleted.

Lastly, because our database schema has changed, our TypeScript definitions are now incorrect. Therefore, we use the Supabase CLI to introspect our PostgreSQL schema and create a new `database.types.ts` file.

## Code Snippets

**Add foreign key relationship to auth.users**

```sql
alter table public.tweets
add user_id uuid references auth.users on delete cascade not null;
```

**Generate TypeScript definitions**

```bash
npx supabase gen types typescript --project-id your-project-id > lib/database.types.ts
```

Setup a Foreign Key relationship between PostgreSQL tables

[Typescript](https://www.typescriptlang.org/) reduces runtime errors and makes our code more maintainable. [Supabase](https://supabase.com/) allows us to introspect our PostgreSQL schema and generate TypeScript definitions.

In this lesson we generate an access token to use the [Supabase CLI](https://supabase.com/docs/guides/cli) and generate TypeScript definitions. Additionally, we write our types to a file, which can be passed to our Supabase client, giving our application full type-safety across client, server and database.

Lastly, we make our Database types globally available so we don't need to import them every time we create a Supabase client.

## Code Snippets

**Login to Supabase CLI**

```bash
npx supabase login
```

**Generate TS definitions file**

```bash
npx supabase gen types typescript --project-id your-project-id > lib/database.types.ts
```

Generate TypeScript Definitions from PostgreSQL Schema with Supabase CLI

Since [Supabase](https://supabase.com/) requires our user to be authenticated to fetch tweets, it doesn't make sense for an unauthenticated user to visit the landing page. In this lesson, we implement protected routes that are only accessible to authenticated users.

Additionally, we create a `/login` route to redirect unauthenticated users, which allows them to sign in with GitHub.

## Code Snippets

**Redirect unauthenticated users**

```tsx
const {
  data: { session },
} = await supabase.auth.getSession();

if (!session) {
  redirect("/login");
}
```

Implement Protected Routes for Authenticated Users with Supabase Auth

The first render of a Client Component happens on the server. This is called Server-side rendering (SSR). However, Client Components are synchronous, so they cannot suspend rendering while fetching data - such as the user's session. This means we either need to display a loading spinner or render the logged out state, while fetching that async data, causing a flash of incorrect state for the user.

In this lesson, we look at rendering a Client Component from a Server Component that can asynchronously fetch the user's [Supabase](https://supabase.com/) session, and pass it as a prop to the Client Component, making the user's session available on its first SSR render.

## Code Snippets

**Render Client Component from Server Component**

```tsx
const {
  data: { session },
} = await supabase.auth.getSession();

return <ClientComponent session={session} />;
```

Dynamically Render UI Based on User Session with SSR in Next.js Client Components

Since we're using [Supabase](https://supabase.com/) to authenticate our users, it knows who our user is throughout the rest of the Supabase environment.

In this lesson, we modify our Row Level Security (RLS) policy to only apply to the `authenticated` role to ensure that only authenticated users can select tweets.

Additionally, we use the `useRouter` hook and `router.refresh()` to run our Server Component again and fetch fresh data from Supabase, after the user signs in or out.

## Code Snippets

**Enable authenticated read access with RLS policy**

```sql
create policy "anyone can select tweets" ON "public"."tweets"
as permissive for select
to authenticated
using (true);
```

Restrict Access to Authenticated Users with Supabase RLS Policies

Server Components cannot set cookies in the [Next.js App Router](https://nextjs.org/docs/app). In this lesson, we implement middleware to refresh expired [Supabase](https://supabase.com/) sessions.

[Middleware](https://nextjs.org/docs/app/building-your-application/routing/middleware) runs immediately before the route is loaded. By using it to refresh our user's session, we ensure it is valid by the time it loads the Server Component and attempts to fetch data from Supabase.

## Code Snippets

**Refresh expired sessions**

```tsx
supabase.auth.getSession();
```

[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.

## Resources

- [Supabase guide to Login with GitHub](https://supabase.com/docs/guides/auth/social-login/auth-github)

Create an OAuth App with GitHub

Our [Supabase](https://supabase.com) project is a hosted PostgreSQL database. In this lesson, we install the [Supabase Auth Helpers](https://www.npmjs.com/package/@supabase/auth-helpers-nextjs) and [Supabase.js](https://www.npmjs.com/package/@supabase/supabase-js) npm packages, and configure environment variables to query data from Supabase:

```
NEXT_PUBLIC_SUPABASE_URL=your-supabase-url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your-supabase-anon-key
```

These values can be found in [your Supabase project's API Settings](https://app.supabase.com/project/_/settings/api).

Additionally, we create a new Supabase instance using the `createServerComponentClient` function, then make our Server Component Async and suspend its rendering until our request for Supabase data resolves.

Lastly, we implement a Row Level Security (RLS) policy to enable read access for the `tweets` table.

## Code Snippets

**Install Supabase packages**

```bash
npm i @supabase/auth-helpers-nextjs @supabase/supabase-js
```

**Import createServerComponentClient function**

```tsx
import { createServerComponentClient } from "@supabase/auth-helpers-nextjs";
import { cookies } from "next/headers";
```

**Create Supabase client in Server Component**

```tsx
const supabase = createServerComponentClient({ cookies });
```

**Fetch data from Supabase**

```tsx
const { data: tweets } = await supabase.from("tweets").select();
```

**Pretty print data with JSON.stringify**

```tsx
<pre>{JSON.stringify(tweets, null, 2)}</pre>
```

**Enable read access with RLS policy**

```sql
create policy "anyone can select tweets" ON "public"."tweets"
as permissive for select
to public
using (true);
```

[Supabase](https://supabase.com/) is a collection of open source tools that wrap around a PostgreSQL database - Hosting, Auth, Realtime, File Storage, Edge Functions etc. In this lesson, we go to [database.new](https://database.new) to create a free Supabase project.

Additionally, we create a `tweets` table and populate it with some seed data.

## Code Snippets

**Create a `tweets` table**

```sql
create table if not exists tweets (
  id uuid default gen_random_uuid() primary key,
  created_at timestamp with time zone default timezone('utc'::text, now()) not null,
  title text not null
);
```

**Insert tweets**

```sql
insert into tweets(title)
values
  ('first tweet'),
  ('second tweet'),
  ('third tweet');
```

Using a GitHub repo to deploy our application to Vercel, keeps our code and live production site in sync. In this lesson we look at using the [GitHub CLI](https://cli.github.com/) tool to create a public repo, and adding it as a remote origin for our project.

Additionally, we create a new Vercel project from this GitHub repo, add our Supabase environment variables, and deploy. Lastly, we update the Homepage URL in our GitHub OAuth app to be our new Vercel URL, and set our Supabase project's [Authentication Site URL](https://app.supabase.com/project/_/auth/url-configuration) to our new live application URL.

## Extension ideas

- Style the app using Tailwind CSS (or another method of choice)
- Implement the ability for a user to `update` and `delete` their own messages
- Add the option to set a username and display this alongside messages
- Add separate message threads/chat rooms
- Implement private messages/chat rooms

Stop waiting for a single AI agent! This lesson demonstrates a powerful workflow to massively parallelize your AI-driven development in Cursor. Learn how to use tools like `file-forge` to package your project context, prompt advanced AI models (like Gemini in AI Studio) to brainstorm features and generate setup scripts, and then leverage a custom `git worktree` CLI tool (`wt`) to automatically launch an "army" of isolated Cursor instances, each tackling a different task on its own branch.

**Workflow Demonstrated / Key Benefits:**

*   **Bundle Project Context:** Use `file-forge` to create an AI-friendly representation of your codebase.
*   **AI-Powered Brainstorming & Scripting:** Prompt a reasoning model (e.g., Gemini via AI Studio) to suggest features *and* generate a shell script (`zsh`/`bash`) to automate setup.
*   **Automated Worktree Creation:** Execute the generated script which uses a custom `git worktree` CLI (`wt`) to:
    *   Create new branches and worktrees for each suggested feature.
    *   Install dependencies automatically (e.g., `pnpm install`).
    *   Launch multiple, isolated Cursor instances.
*   **Parallel AI Development:** Assign different features or implementation approaches to each Cursor agent (Composer) simultaneously.
*   **Efficient Monitoring:** Easily switch between active Cursor projects/worktrees using `Ctrl+R` or OS spaces.
*   **Seamless Integration:** Merge completed features back into your main branch using `wt merge` or use agents to commit, push, and create Pull Requests via the GitHub CLI (`gh pr create`).
*   **Boost Productivity:** Dramatically speed up iteration and experimentation by running multiple AI agents concurrently without conflicts.

This approach transforms your workflow, allowing you to explore multiple development paths simultaneously and integrate the best results efficiently using standard Git practices.

Up and Running with Tanstack Router and React

Learn TanStack Router for React: set up apps, use file-based routing, manage routes, and boost app performance.


In this lesson, we explore how TanStack Router integrates with the [native browser history API](https://developer.mozilla.org/en-US/docs/Web/API/History) to manage navigation.

As we navigate through different routes, the URL changes are stored in the browser's history, allowing users to use the forward and backward buttons to traverse their navigation history.

This functionality also **enables permalinks**, meaning users can copy and paste URLs to access specific routes directly.

Additionally, we learn how to programmatically interact with the history object to move forward or backward through the navigation stack, enhancing the user experience by providing full control over navigation actions.

This compatibility with the native history API ensures that TanStack Router applications behave similarly to traditional websites, offering a seamless and intuitive user experience.

In this lesson, we explore how to hook into TanStack Router's lifecycle hooks to execute custom logic during route changes.

The hooks we'll look into are: `onEnter`, `onStay`, and `onLeave`, which are triggered when entering, staying within, or leaving a route, respectively.

All hooks receive a detailed match parameter, providing information about the route's path, ID, and tons of other details.

This allows for the implementation of features like animations or logging when navigating between routes.

We also learn how to use these hooks to track and manage state changes as users interact with the application, making it easier to implement complex behaviors based on route transitions.

In this lesson, we learn how to handle not found errors in TanStack Router by using the `notFoundComponent` at both nested and global levels.

To trigger the display of a `notFoundComponent`, we must throw a specific error using the `notFound` function within a loader or other lifecycle method of a route. This approach allows us to provide custom error messages for specific routes or globally across the application.

We explore how to define a notFoundComponent within a specific route's configuration and how to set a `defaultNotFoundComponent` at the router global level, which applies to all routes unless overridden locally. This flexibility ensures that users receive meaningful feedback when encountering non-existent routes.

In this lesson, we learn how to access dynamic route parameters using the `useParams` hook in TanStack Router.

When used with a specific `Route` object, `useParams` provides type-safe access to route parameters, ensuring that TypeScript knows the exact types of these parameters.

This approach eliminates the possibility of undefined/optional values, making it safer for accessing parameters like `employeeId`.

However, when using `useParams` globally without specifying a route, it requires an options object with `{ strict: false }`, which reduces type safety.

In this case, the hook can access parameters from any route in the application, but it does not guarantee their existence or type. This flexibility allows components to be reused across different routes, but it requires careful handling of potential errors.

In this lesson, we learn how to reorganize file-based routes in TanStack Router to accommodate nested routing structures.

We explore how to create additional nested routes by converting files into directories, allowing for further nesting.

For example, to create a nested route like `/employees/$employeeId/edit`, we can create a **directory** (!) named `$employeeId` and place an `index.tsx` file inside it to define the route component for this nested route.

This approach provides flexibility in organizing files while maintaining the convention that file names and locations align with route paths. We also see how to adapt existing components and loaders to work with these reorganized routes, enabling features like edit forms or delete actions (or whatever) within nested routes.

In this lesson, we learn how to parametrize the loader for a nested route in TanStack Router.

We focus on a nested route like `/employees/$employeeId`, where the `$employeeId` is a **dynamic parameter**.

To fetch data for this route, we use a `loader` function that accesses the `$employeeId` parameter. This is achieved by using the params object available in the `loader` function, which contains the dynamic segments of the URL. We then use this parameter to call a function like `getEmployeeById`, which fetches specific employee details from an API.

We highlights that TanStack Router **automatically infers types** for these parameters, ensuring type safety for nested routes.
