Node.js Usage

For Node.js applications (CLI tools, servers, etc.), use the Node.js-specific import for full functionality including file system access and automatic browser launching.

Basic Usage

import { ClaudeAuth } from '@vibe-kit/auth/node';

// Start OAuth flow (opens browser automatically)
const token = await ClaudeAuth.authenticate();

// Check if authenticated
const isAuthenticated = await ClaudeAuth.isAuthenticated();

// Get valid token (auto-refresh if needed)
const accessToken = await ClaudeAuth.getValidToken();

// Verify authentication
const isValid = await ClaudeAuth.verify();

// Get authentication status
const status = await ClaudeAuth.getStatus();

// Logout
await ClaudeAuth.logout();

Token Import/Export

Node.js environments support importing and exporting tokens in various formats:

import { ClaudeAuth } from '@vibe-kit/auth/node';

// Export token in different formats
const envToken = await ClaudeAuth.exportToken('env');
const jsonToken = await ClaudeAuth.exportToken('json');
const fullToken = await ClaudeAuth.exportToken('full');

// Import from various sources
await ClaudeAuth.importToken({ fromEnv: true });
await ClaudeAuth.importToken({ fromFile: './token.json' });
await ClaudeAuth.importToken({ refreshToken: 'your-refresh-token' });

Using with AI Provider APIs

Claude AI (Available Now)

import { ClaudeAuth } from '@vibe-kit/auth/node';

// Authenticate and get token
let accessToken = await ClaudeAuth.getValidToken();
if (!accessToken) {
  await ClaudeAuth.authenticate();
  accessToken = await ClaudeAuth.getValidToken();
}

// Use with Claude Code CLI
// First, export the token as an environment variable:
// export CLAUDE_CODE_OAUTH_TOKEN=${accessToken}
// claude -p 'Hello, Claude!'

With Official SDKs

// Claude AI with Anthropic SDK
import Anthropic from '@anthropic-ai/sdk';
import { ClaudeAuth } from '@vibe-kit/auth/node';

const accessToken = await ClaudeAuth.getValidToken();
const anthropic = new Anthropic({
  apiKey: '', // Leave empty for OAuth
  authToken: accessToken, // Use your MAX subscription token
});

const message = await anthropic.messages.create({
  model: 'claude-sonnet-4-20250514',
  max_tokens: 1000,
  messages: [{ role: 'user', content: 'Hello!' }]
});

Storage Options

Node.js environments use MemoryTokenStorage by default, providing in-memory storage for server-side applications with secure file system token persistence.
