## Conference Profile
12
For starters, we're going to have a custom conference profile. Attendees and speakers (and anyone else!) can login and create an extended profile. Inspired by [Discover Toronto](https://discover.toronto.inc/), we had an [initial discussion in the forum](https://discourse.atprotocol.community/t/conference-profiles/186) and are going to work on fleshing this out here with detailed issues.

## 🚀 Project Structure

Inside of your Astro project, you'll see the following folders and files:
25
26
```text
27
/
28
├── public/
29
├── src/
30
-
│ └── pages/
31
-
│ └── index.astro
32
└── package.json
33
```
34
-
35
-
Astro looks for `.astro` or `.md` files in the `src/pages/` directory. Each page is exposed as a route based on its file name.
36
-
37
-
There's nothing special about `src/components/`, but that's where we like to put any Astro/React/Vue/Svelte/Preact components.
38
-
39
-
Any static assets, like images, can be placed in the `public/` directory.

# Astro ATProto OAuth Starter
15
+
16
+
A minimal [Astro](https://astro.build) starter template demonstrating OAuth authentication with AT Protocol (ATProto), the decentralized social networking protocol used by Bluesky and other services.
17
+
18
+
This starter includes:
19
+
- Complete OAuth authentication flow using `@atproto/oauth-client-node`
20
+
- Cookie-based session management
21
+
- Profile display after authentication
22
+
- Login/logout endpoints
23
+
- Tailwind CSS and DaisyUI styling
24
+
25
+
## 🚀 Getting Started
26
+
27
+
1. **Install dependencies:**
28
+
```sh
29
+
npm install
30
+
```
31
32
+
2. **Configure environment variables:**
33
+
```sh
34
+
cp .env.template .env
35
+
```
36
+
Edit `.env` if you need to change the port (default: 4321) or set a public URL.
37
38
+
3. **Start the development server:**
39
+
```sh
40
+
npm run dev
41
+
```
42
+
The app will be available at `http://localhost:4321`
43
44
+
4. **Try logging in:**
45
+
Enter your AT Protocol handle (e.g., `alice.bsky.social`) to authenticate.
