Importance of Databases in Backend Development

Highlighting the role of databases in backend systems, including relational and NoSQL databases, SQL vs. NoSQL comparisons, and use cases.

Understanding Relational and NoSQL Databases

Exploring relational databases (SQL) and NoSQL databases (MongoDB) in terms of data structure, relationships, and scalability in backend applications.

ORMs for Database Interactions

Discussing Object-Relational Mapping (ORM) tools like Prisma and Mongoose to simplify database interactions, queries, and data modeling in backend development.

API Best Practices and Naming Conventions

Outlining API best practices, including HTTP methods, endpoints, response structures, validation, and naming conventions for efficient API design.

Setting Up Environment Variables for API Configurations

Guiding on setting up environment variables for different environments, handling configurations, database connections, and application settings.

Creating API Routes and Endpoints

Creating organized API routes and endpoints for user management, subscriptions, and CRUD operations with proper naming conventions and structure.

Database Setup with MongoDB Atlas

Setting up a MongoDB database using MongoDB Atlas, including creating a project, database cluster, user credentials, and connecting to Node.js.

Creating Models in Mongoose

Explained how to create models in Mongoose, including defining schemas, validating data, and setting timestamps.

Creating MongoDB Models

Demonstrated how to create MongoDB models for subscriptions, including defining fields like subscription name, price, currency, frequency, and status.

Creating Controllers and Routes

Showed how to create controllers and routes for sign-up, sign-in, and sign-out functionalities in the application.

Error Handling Middleware

Implemented error handling middleware to catch and handle different types of errors like bad object IDs, casting errors, and validation errors in the application.

Authorization Middleware

Implemented authorization middleware to protect routes and allow access based on user authentication using tokens, demonstrating user authorization and user details retrieval.

Rate Limiting and Bot Protection

Explained the importance of rate limiting and bot protection in preventing abuse and spam, demonstrated setting up rate limiting using the ArcJet middleware, and showcased how it blocks excessive requests.

Creating Subscriptions

Focuses on creating subscriptions, tracking them, and canceling them using the Subscription Controller in the API.

Populating User Information

Explains how to populate user information in the subscription routes to validate requests and ensure authorization procedures before creating documents in the application.

Implementing Secure API Endpoints

Discusses the importance of writing type-safe and secure API endpoints to enhance application security and reliability.

Testing Subscription Creation

Provides a demonstration of testing the subscription creation by making a post request and filling in the necessary information like currency, frequency, and date.

Retrieving User Subscriptions

Describes the process of retrieving user subscriptions and displaying them using an asynchronous function in the controller.

Implementing Workflow Algorithm

Explains the workflow algorithm for managing subscription reminders and deadlines to enhance user experience and engagement.

Configuring Workflow Routes

Guides through configuring workflow routes by setting up a base URL and token in the workflow file to manage different workflows efficiently.
