Step-by-Step Guide: Onboarding Restaurants to Your Node.js Food Order App

Short Summary:

This video tutorial demonstrates the step-by-step onboarding process for restaurants onto a Node.js-based food order application. Key points include creating and managing vendor accounts in a MongoDB database using Mongoose, implementing user authentication with bcrypt for password hashing, and securing API endpoints with JWT (JSON Web Tokens) for authorization. The tutorial covers creating RESTful APIs for vendor creation, retrieval, and updating, using Express.js for routing and handling requests. The process involves creating and utilizing helper functions and middleware for error handling, code reusability, and authentication. The application's implication is a streamlined process for adding restaurants to the food ordering platform, ensuring secure access and data management. Specific technologies mentioned include Node.js, Express.js, MongoDB, Mongoose, bcrypt, JWT, and Studio 3T (a MongoDB GUI).

Detailed Summary:

The video is divided into several sections focusing on different aspects of integrating restaurants into the food ordering app:

Section 1: Admin Controller Enhancements and Database Cleanup:

This section begins by reviewing the previously created vendor functionality within the admin controller. The developer demonstrates listing all vendors and retrieving a vendor by ID using Mongoose's find and findOne methods. Due to duplicate data from previous testing, the database is cleared using Studio 3T, a MongoDB GUI. New vendor entries are then created and successfully retrieved, showcasing the functionality of the API endpoints.

Section 2: Refactoring and Error Handling:

The code is refactored to reduce redundancy by creating a reusable function for finding vendors by ID or email. The developer mentions plans to implement more robust error handling using helper classes within a utility directory, but this is deferred for later. The functionality of retrieving vendors by ID is tested and confirmed.

Section 3: Vendor Login and Authentication:

This section introduces vendor login functionality. A new vendorController is created, and a login endpoint is implemented. Password validation is performed using bcrypt's comparison function within a custom validatePassword function in the utility directory. Successful and unsuccessful login attempts are demonstrated, showcasing the validation process.

Section 4: JWT Implementation for Authorization:

To secure the vendor profile and update endpoints, JWT (JSON Web Tokens) are introduced. A new function to generate JWT signatures is added to the passwordUtility file, using a secret key from a config file. The structure of the JWT payload is defined in a new AuthDTO file. A middleware function is created to verify JWTs and add the decoded payload to the request object, enabling access to user information within subsequent route handlers.

Section 5: Vendor Profile and Service Updates:

The authenticate middleware is applied to the /vendor/profile and /vendor/service endpoints to protect them. The developer demonstrates updating the vendor profile and toggling the service availability status. Successful updates are shown, highlighting the functionality of the authentication and update mechanisms. The video concludes with a preview of future additions, including adding food items and profile pictures. Notably, the speaker emphasizes the importance of secure access control and data management throughout the process.
