    Function authenticatedRequestHandler

    • Higher-order helper function to enforce authentication on a request handler and assert the type of Request that is passed into your authenticated Express routes.

      This function takes an AuthenticatedRequestHandler and returns a new request handler that verifies that the request has a 'user' property with the correct shape on it before calling the original handler. If the req.user property isn't the correct shape, it sends a 401 Unauthorized response to the client.

      NOTE: This does not verify signatures or any other content -- use getAuthenticateUserExpressHandler to create a middleware that does those things and ensure that your routes use it.

      See express.js documentation for details on writing your route handler

      Parameters

      • handler: AuthenticatedRequestHandler

      Returns (req: Request, res: Response, next: NextFunction) => void | Promise<void>

      import { expressAuthHelpers } from '@lit-protocol/vincent-sdk';
      const { authenticatedRequestHandler, getAuthenticateUserExpressHandler } = expressAuthHelpers;

      import type { ExpressAuthHelpers } from '@lit-protocol/vincent-sdk';

      // Define an authenticated route handler
      const getUserProfile = async (req: ExpressAuthHelpers['AuthenticatedRequest'], res: Response) => {
        // Access authenticated user information
        const { pkpAddress } = req.user;

        // Fetch and return user data
        const userData = await userRepository.findByAddress(pkpAddress);
        res.json(userData);
      };

      // Use in Express route with authentication
      app.get('/profile', authenticateUser, authenticatedRequestHandler(getUserProfile));
