## Development Workflows

I can assist with:

1. Adding new API routes
2. Creating frontend components
3. Setting up middleware
4. Debugging CORS issues
5. TypeScript type definitions
6. Tailwind styling
7. Production deployment

## Code Navigation

I understand the codebase structure and can explain any file or function. Reference files like:

```typescript:server/src/routes/hello.ts
startLine: 1
endLine: 25
```

## Error Resolution

For any error, I'll:

1. Identify the root cause
2. Suggest immediate fixes
3. Explain how to prevent similar issues
4. Provide relevant code examples

## Best Practices

I'll guide you on:

1. TypeScript type safety
2. API error handling
3. State management
4. Performance optimization
5. Security considerations

Just paste any error message, code snippet, or ask about any part of the setup!

### 🪙 Minting Tokens

1. Copy the token metadata template:

```bash
cp token_metadata.example.jsonc token.jsonc
```

2. Edit `token.jsonc` with your token details:

```jsonc
{
  "name": "YourToken", // Token name
  "symbol": "TOKEN", // Token symbol (2-6 chars)
  "description": "Your token description",
  "websiteLink": "https://yoursite.com",
  "twitter": "your_twitter_handle",
  "discord": "https://discord.gg/your_server",
  "telegram": "your_bot_telegram_username",
  "nsfw": false,
  "image": "ipfs://your_ipfs_hash", // Upload image to IPFS first
}
```

3. Update `.env` to point to your token file:

```env
TOKEN_DETAILS_PATH=token.jsonc
```

4. Start your bot and use the `/mint` command in Telegram. The bot will:

- Read your token config
- Mint on Base Sepolia testnet
- Return contract details and token page URL

> Note: Make sure you have set up your COLLABLAND_API_KEY and TELEGRAM_BOT_TOKEN in .env first.

## 🔥 Developing Lit Actions

### Setup

1. Navigate to lit-actions directory:

```bash
cd lit-actions
pnpm install
```

2. Configure environment:

```bash
cp .env.example .env
```

Required variables:

- `PINATA_JWT`: Your Pinata JWT for IPFS uploads
- `PINATA_URL`: Pinata gateway URL

### Development Workflow

1. Create new action in `src/actions/`:

```typescript
/// <reference path="../global.d.ts" />

const go = async () => {
  // Access Lit SDK APIs
  const tokenId = await Lit.Actions.pubkeyToTokenId({ publicKey });

  // Sign data
  const signature = await Lit.Actions.signEcdsa({
    publicKey,
    toSign,
    sigName,
  });

  // Return response
  Lit.Actions.setResponse({
    response: JSON.stringify({ result: "success" }),
  });
};

go();
```

2. Start development server:

```bash
pnpm run dev
```

This will:

- Build TypeScript → JavaScript
- Bundle with dependencies
- Inject SDK shims
- Upload to IPFS
- Watch for changes

### Adding SDK Shims

1. Create shim in `shims/`:

```javascript
// shims/my-sdk.shim.js
import { MySDK } from "my-sdk";
globalThis.MySDK = MySDK;
```

2. Update types in `src/global.d.ts`:

```typescript
declare global {
  const MySDK: typeof MySDK;
}
```

### Building & Deployment

```bash
# Build only
pnpm run build

# Build & deploy to IPFS
pnpm run start
```

IPFS hashes are saved to `actions/ipfs.json`:

```json
{
  "my-action.js": {
    "IpfsHash": "Qm...",
    "PinSize": 12345,
    "Timestamp": "2025-01-03T..."
  }
}
```

### Available APIs

The Lit Actions runtime provides:

- **Lit.Actions**

  - `signEcdsa()`: Sign data with PKP
  - `pubkeyToTokenId()`: Convert public key to token ID
  - `getPermittedAuthMethods()`: Get permitted auth methods
  - `checkConditions()`: Check access control conditions
  - `setResponse()`: Return data to client
  - Full API in `src/global.d.ts`

- **Built-in SDKs**
  - `ethers`: Ethereum interactions
  - `Buffer`: Buffer utilities

### Best Practices

1. **Type Safety**

   - Always reference `global.d.ts`
   - Define types for parameters
   - Use TypeScript features

2. **SDK Management**

   - Create minimal shims
   - Document SDK versions
   - Test SDK compatibility

3. **Action Structure**

   - One action per file
   - Clear async/await flow
   - Proper error handling

4. **Deployment**
   - Test locally first
   - Verify IPFS uploads
   - Keep actions small

### Scripts

```bash
pnpm run dev        # Development mode
pnpm run build     # Build actions
pnpm run start     # Deploy to IPFS
pnpm run lint      # Fix code style
pnpm run watch     # Watch mode
```

### Project Structure

```
