## Key Upload Methods Distinction

• `uploadFile` Method
  - Purpose: Single file upload
  - Content-Type Requirements:
    * REQUIRES manual Content-Type tag specification
    * Must be included in dataItemOpts.tags
    * Without proper Content-Type, files become inaccessible in original format
  - Usage Pattern:
    * Direct file-to-file upload
    * No automatic MIME type detection
    * No folder structure preservation
  - Best For:
    * Individual file uploads
    * Custom tag requirements
    * Direct control over Content-Type
  - Not For:
    * Recursively uploading files in a folder

• `uploadFolder` Method
  - Purpose: Multiple files/directory upload
  - Content-Type Handling:
    * AUTOMATIC Content-Type detection for all files
    * No manual tag specification needed
    * Preserves file accessibility automatically
  - Features:
    * Creates Arweave manifest
    * Preserves folder structure
    * Handles concurrent uploads
    * Built-in retry logic
  - Environment-Specific Requirements:
    * Node.js: Uses folderPath parameter
    * Web: Uses files parameter (File[] from input/drag-drop)
  - Best For:
    * Directory uploads
    * Bulk file uploads
    * Maintaining folder structure
    * Automatic MIME type handling
    * Node operations
  - Common Mistakes:
    * The SDK handles fetching and preparing the folder for upload, there is no need to do so manually, or to interact with individual files in any way. Simply providing the folder path is sufficient //*EXTREMELY IMPORTANT*
    * `folderPath` is used for Node environments, `files` is used in Web environments. There is never a cause to provide both.

This document provides a structured reference of the Turbo SDK for AI consumption. It contains key information about the SDK's functionality, methods, parameters, and usage patterns.

## Overview

The `@ardrive/turbo-sdk` provides functionality for interacting with the Turbo Upload and Payment Services. It's available for both NodeJS and Web environments and supports various cryptocurrencies for funding and payments.

## Installation

```bash
npm install @ardrive/turbo-sdk
# or
yarn add @ardrive/turbo-sdk
```

> **Note**: For detailed information about the Turbo CLI and its commands, see the [CLI Documentation for AI](https://docs.ardrive.io/docs/turbo/turbo-sdk/ai-cli.html).

## Turbo Credits System

Turbo Credits are the payment mechanism used for uploading files and folders to Arweave through the Turbo service. The SDK provides two primary methods for purchasing credits:

1. **Fiat Currency Purchases** (`createCheckoutSession`)
   - Purchase credits using traditional currencies (USD, EUR, etc.)
   - Processed through a secure payment service
   - Example:
     ```typescript
     const checkoutSession = await turbo.createCheckoutSession({
       amount: USD(10.0),
       owner: publicArweaveAddress
     });
     ```

2. **Cryptocurrency Purchases** (`topUpWithTokens`)
   - Purchase credits using supported cryptocurrencies
   - Direct blockchain transaction from your wallet
   - Automatically converts crypto to credits at current rates
   - Example:
     ```typescript
     const topUpResult = await turbo.topUpWithTokens({
       tokenAmount: WinstonToTokenAmount(100_000_000) // 0.0001 AR
     });
     ```

Credits are stored in your wallet and are automatically used when uploading files or folders. The SDK provides methods to:
- Check balance: `getBalance()`
- Share credits: `shareCredits()`
- Revoke shared credits: `revokeCredits()`
- List credit shares: `getCreditShareApprovals()`

### Credit Management Features

1. **Balance Checking**
   ```typescript
   const balance = await turbo.getBalance();
   console.log({
     controlledWinc: balance.controlledWinc,    // Credits you own
     effectiveBalance: balance.effectiveBalance  // Including shared credits
   });
   ```

2. **Credit Sharing**
   ```typescript
   const approval = await turbo.shareCredits({
     approvedAddress: "recipient-address",
     approvedWincAmount: BigNumber.from("1000000"),
     expiresBySeconds: 86400 // Optional 24-hour expiry
   });
   ```

3. **Credit Usage**
   - Credits are automatically deducted during uploads
   - Can specify which wallet pays using `paidBy` option
   - Can prioritize different credit sources using `useSignerBalanceFirst`

## Supported Tokens

The SDK supports the following tokens:
- Arweave (AR)
- Ethereum (ETH)
- Solana (SOL)
- Polygon (MATIC/POL)
- KYVE
- Ethereum on Base (ETH on Base) - Added in v1.23.0

> **IMPORTANT**: The token being used must be specified when authenticating the TurboFactory instance. The correct token type must be specified at authentication because it affects how the class expects the signer to be formatted and how transactions are processed.


## Content-Type Tags

> **EXTREMELY IMPORTANT**: Content-Type tags are REQUIRED for all `turbo.uploadFile()` calls to ensure proper viewing and accessibility. Without a Content-Type tag, browsers cannot determine how to display the file, and it will only be downloadable as binary data.

> **NOTE**: For `turbo.uploadFolder()` calls, Content-Type tags are automatically detected and added for each file. You do not need to manually specify Content-Type tags when using `uploadFolder()`.

### Common MIME Types:
- Text files: `text/plain`, `text/html`, `text/css`, `text/javascript`
- Images: `image/jpeg`, `image/png`, `image/gif`, `image/svg+xml`
- Documents: `application/pdf`, `application/msword`, `application/vnd.openxmlformats-officedocument.wordprocessingml.document`
- Audio: `audio/mpeg`, `audio/wav`
- Video: `video/mp4`, `video/webm`
- JSON: `application/json`

### Adding Content-Type Tags:
```typescript
// In SDK
await turbo.uploadFile({
  fileStreamFactory: () => fs.createReadStream('document.pdf'),
  fileSizeFactory: () => fs.statSync('document.pdf').size,
  dataItemOpts: {
    tags: [
      { name: "Content-Type", value: "application/pdf" }
    ]
  }

## Core Components

### TurboFactory

The main entry point for creating Turbo clients.

#### Methods

1. `unauthenticated(options?: TurboUnauthenticatedOptions): TurboUnauthenticatedClient`
   - Creates an instance for accessing unauthenticated services
   - Parameters:
     - `options`: Optional configuration including token type and service URLs

2. `authenticated(options: TurboAuthenticatedOptions): TurboAuthenticatedClient`
   - Creates an instance for accessing authenticated services
   - Parameters:
     - `options`: Required configuration including authentication details
     - Must include either `privateKey` or `signer`
     - Must include `token` for non-Arweave chains (ethereum, solana, etc.)

### Authentication Options

> **IMPORTANT UPDATE**: Wallet adapters have been deprecated. Authentication is now handled through either direct private key usage or signer instances. For web environments, signers can be created by passing the appropriate wallet provider (e.g., window.ethereum, window.solana, window.arweaveWallet) to the corresponding signer class.

The SDK supports two primary authentication methods:
1. Using a private key directly
2. Using a signer instance

Each authentication method must implement the `TurboDataItemSigner` interface:
- `signDataItem(dataItem: DataItem): Promise<DataItem>` - Signs a data item
- `getNativeAddress(): Promise<string>` - Returns the native address of the signer

> **IMPORTANT**: For EVM-based tokens (Ethereum, Polygon, ETH on Base), specify the correct token type in the options. While the authentication method remains the same, the network and endpoints will differ based on the specified token.

#### Node.js Environment Examples:

1. **Arweave JWK**
   ```typescript
   const turbo = TurboFactory.authenticated({ privateKey: jwk });
   ```

2. **Ethereum Private Key**
   ```typescript
   const turbo = TurboFactory.authenticated({
     privateKey: ethHexadecimalPrivateKey,
     token: "ethereum"
   });
   ```

3. **Solana Secret Key**
   ```typescript
   const turbo = TurboFactory.authenticated({
     privateKey: bs58.encode(secretKey),
     token: "solana"
   });
   ```

#### Web Environment Examples:

1. **Arweave with ArConnect**
   ```typescript
   import { TurboFactory, ArconnectSigner } from '@ardrive/turbo-sdk';

   const signer = new ArconnectSigner(window.arweaveWallet);
   const turbo = TurboFactory.authenticated({ signer });
   ```

2. **Ethereum with Web3 Provider**
   ```typescript
   import { TurboFactory, EthereumSigner } from '@ardrive/turbo-sdk';

   // Using window.ethereum (MetaMask or similar)
   const signer = new EthereumSigner(window.ethereum);
   const turbo = TurboFactory.authenticated({ 
     signer,
     token: 'ethereum'
   });
   ```

3. **Solana with Web3 Provider**
   ```typescript
   import { TurboFactory, HexInjectedSolanaSigner } from '@ardrive/turbo-sdk';

   // Using window.solana (Phantom or similar)
   const signer = new HexInjectedSolanaSigner(window.solana);
   const turbo = TurboFactory.authenticated({ 
     signer,
     token: 'solana'
   });
   ```

> **NOTE**: When using a signer directly, you don't need to specify the `token` type for Arweave as it's the default. However, for other chains (Ethereum, Solana, etc.), you must specify the correct `token` type to ensure proper network and endpoint configuration.

           value: "My App"
         },
         {
           name: "Unix-Time",
           value: Date.now().toString()
         }
       ]
     },
     signal: AbortSignal.timeout(30000)  // 30 second timeout
   });

   console.log('File uploaded!', {

     fastFinalityIndexes: result.fastFinalityIndexes
   });
   ```

   ### Web Environment Example:
   ```typescript
   import { TurboFactory } from '@ardrive/turbo-sdk';

   // Initialize authenticated client
   const turbo = TurboFactory.authenticated({ signer });

   // HTML input element
   <input 
     type="file" 
     id="file-input" 
     accept="image/*,video/*,audio/*,.pdf,.txt"
   />

   // JavaScript/TypeScript
   const fileInput = document.getElementById('file-input');
   
   fileInput.addEventListener('change', async (event) => {
     const file = fileInput.files[0];
     if (!file) return;
     
     try {
       const result = await turbo.uploadFile({
         fileStreamFactory: () => file.stream(),
         fileSizeFactory: () => file.size,
         dataItemOpts: {
           tags: [
             {
               name: "Content-Type",
               value: file.type || 'application/octet-stream'  // Use file's MIME type or fallback
             }
           ]
         }
       });

       console.log('File uploaded!', {
         id: result.id,
         url: `https://arweave.net/${result.id}`,
         owner: result.owner,
         dataCaches: result.dataCaches,
         fastFinalityIndexes: result.fastFinalityIndexes
       });
     } catch (error) {
       console.error('Upload failed:', error);
     }
   });

   // With drag and drop
   const dropZone = document.getElementById('drop-zone');
   
   dropZone.addEventListener('dragover', (e) => {
     e.preventDefault();
     e.stopPropagation();
     dropZone.classList.add('drag-over');
   });
   
   dropZone.addEventListener('dragleave', (e) => {
     e.preventDefault();
     e.stopPropagation();
     dropZone.classList.remove('drag-over');
   });
   
   dropZone.addEventListener('drop', async (e) => {
     e.preventDefault();
     e.stopPropagation();
     dropZone.classList.remove('drag-over');
     
     const file = e.dataTransfer.files[0];
     if (!file) return;
     
     try {
       const result = await turbo.uploadFile({
         fileStreamFactory: () => file.stream(),
         fileSizeFactory: () => file.size,
         dataItemOpts: {
           tags: [
             {
               name: "Content-Type",
               value: file.type || 'application/octet-stream'
             },
             {
               name: "Upload-Method",
               value: "drag-and-drop"
             }
           ]
         },
         signal: AbortSignal.timeout(60000)  // 1 minute timeout
       });
       
       console.log('Dropped file uploaded!', {
         id: result.id,
         url: `https://arweave.net/${result.id}`,
         dataCaches: result.dataCaches
       });
     } catch (error) {
       console.error('Upload failed:', error);
     }
   });
   ```

   The response includes:
   ```typescript
   {
     id: TransactionId;  // The unique transaction ID
     owner: PublicArweaveAddress;  // The wallet address that owns this upload
     dataCaches: string[];  // URLs where the data can be accessed
     fastFinalityIndexes: string[];  // Fast finality index locations
     winc: string;  // Amount of winc spent on the upload
   }
   ```

   > **IMPORTANT NOTES**:
   > 1. Always include a Content-Type tag when using `uploadFile` to ensure proper file viewing
   > 2. The `fileStreamFactory` must return a NEW stream each time it's called
   > 3. The file size must be known before upload
   > 4. For large files, consider implementing progress tracking using stream events
   > 5. Always handle errors appropriately as network issues or insufficient funds can cause failures

## Token-Specific Operations

### Funding with Tokens

> **IMPORTANT**: The token type specified during TurboFactory authentication determines which network and wallet will be used for funding operations. Make sure to authenticate with the correct token type before calling `topUpWithTokens()`.

1. **Arweave (AR)**
   ```typescript
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: WinstonToTokenAmount(100_000_000) // 0.0001 AR
   });
   ```

2. **Ethereum (ETH)**
   ```typescript
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: ETHToTokenAmount(0.00001) // 0.00001 ETH
   });
   ```

3. **Solana (SOL)**
   ```typescript
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: SOLToTokenAmount(0.00001) // 0.00001 SOL
   });
   ```

4. **Polygon (POL/MATIC)**
   ```typescript
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: POLToTokenAmount(0.00001) // 0.00001 POL
   });
   ```

5. **KYVE**
   ```typescript
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: KYVEToTokenAmount(0.00001) // 0.00001 KYVE
   });
   ```

6. **ETH on Base Network** (Added in v1.23.0)
   ```typescript
   const turbo = TurboFactory.authenticated({
     privateKey: ethHexadecimalPrivateKey,
     token: 'base-eth'
   });
   
   const topUpResult = await turbo.topUpWithTokens({
     tokenAmount: ETHToTokenAmount(0.00001) // 0.00001 ETH on Base
   });
   ```

### Fiat Top-Up for Different Tokens

1. **Arweave (AR)**
   ```typescript
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicArweaveAddress
   });
   ```

2. **Ethereum (ETH)**
   ```typescript
   const turbo = TurboFactory.unauthenticated({ token: 'ethereum' });
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicEthereumAddress
   });
   ```

3. **Solana (SOL)**
   ```typescript
   const turbo = TurboFactory.unauthenticated({ token: 'solana' });
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicSolanaAddress
   });
   ```

4. **Polygon (POL/MATIC)**
   ```typescript
   const turbo = TurboFactory.unauthenticated({ token: 'pol' });
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicPolygonAddress
   });
   ```

5. **KYVE**
   ```typescript
   const turbo = TurboFactory.unauthenticated({ token: 'kyve' });
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicKyveAddress
   });
   ```

6. **ETH on Base Network** (Added in v1.23.0)
   ```typescript
   const turbo = TurboFactory.unauthenticated({ token: 'base-eth' });
   const checkoutSession = await turbo.createCheckoutSession({
     amount: USD(10.0),
     owner: publicBaseEthAddress
   });
   ```



## Credit Sharing

The SDK supports sharing credits between wallets:

1. **Creating Approvals**
   - Share credits with another wallet
   - Set amount and expiration time
   - Original owner retains control

2. **Using Shared Credits**
   - Recipients can use shared credits for uploads
   - Credits cannot be re-shared
   - Requires specifying the source wallet

3. **Revoking Approvals**
   - Original owner can revoke at any time
   - Unused credits are returned to owner
   - All approvals for a recipient can be revoked at once

## Latest Features

### v1.23.0 (2025-02-27)
- Added support for ETH on Base network for funding and payments
- New methods and CLI commands for funding with ETH on Base network
- Use token type 'base-eth' to specify ETH on Base network

## Environment Support

- **NodeJS**: Both CommonJS and ESM formats
- **Web**: Compatible with bundlers (Webpack, Rollup, ESbuild)
- **Browser**: Direct usage via script tags

## Type Definitions

The SDK provides TypeScript type definitions for all methods and parameters.

## Method Signatures

@method-signatures {
  uploadFile: {
    name: "uploadFile",
    type: "async",
    parameters: {
      fileStreamFactory: "() => FileStream",
      fileSizeFactory: "() => number",
      dataItemOpts: "Optional<DataItemOptions>",
      signal: "Optional<AbortSignal>"
    },
    returns: "Promise<UploadResponse>",
    requirements: ["Content-Type tag recommended", "New stream per call"]
  },
  uploadFolder: {
    name: "uploadFolder",
    type: "async",
    parameters: {
      folderPath: "string (NodeJS)",
      files: "File[] (Web)",
      dataItemOpts: "Optional<DataItemOptions>",
      manifestOptions: "Optional<ManifestOptions>"
    },
    returns: "Promise<UploadFolderResponse>",
    features: ["Automatic MIME type detection", "Concurrent uploads", "Manifest generation"]
  }
}

## Data Flow

@data-flow {
  authentication: [
    "TurboFactory.authenticated()",
    "→ Signer validation",
    "→ Client instance creation"
  ],
  fileUpload: [
    "File selection",
    "→ Stream creation",
    "→ Content-Type detection",
    "→ Data item signing",
    "→ Upload to service"
  ],
  folderUpload: [
    "Folder/Files selection",
    "→ Concurrent processing",
    "→ Manifest generation",
    "→ Batch uploading",
    "→ Response aggregation"
  ]
}

## Error Handling

@error-patterns {
  authentication: ["InvalidSigner", "NetworkError", "TokenMismatch"],
  upload: ["InsufficientFunds", "StreamError", "TimeoutError"],
  validation: ["InvalidContentType", "FileSizeMismatch", "ManifestError"]
}

## Upload Methods Comparison

> **IMPORTANT DISTINCTION**:

### uploadFile
- Requires manual specification of Content-Type tag in `dataItemOpts.tags`
- Used for single file uploads
- Without Content-Type tag, files will be inaccessible in their original format

Example:
```typescript
await turbo.uploadFile({
  fileStreamFactory: () => fs.createReadStream('document.pdf'),
  fileSizeFactory: () => fs.statSync('document.pdf').size,
  dataItemOpts: {
    tags: [
      { name: "Content-Type", value: "application/pdf" }  // REQUIRED
    ],
    paidBy: "optional-wallet-address"  // Optional
  }
});
```

### uploadFolder
- Automatically detects and sets Content-Type tags for all files
- Used for uploading multiple files/directories
- No need to manually specify Content-Type tags
- Creates a manifest to preserve folder structure

Example:
```typescript
await turbo.uploadFolder({
  folderPath: './my-folder',
  dataItemOpts: {
    tags: [
      { name: "App-Name", value: "My App" }  // Optional custom tags
    ],
    paidBy: "optional-wallet-address"  // Optional
  }
});
```
