Beginner Guide: Web-based application and API service common features

**

Common Features in Any Web-Based Application

**
Here’s a rundown of the basic and common features that are generally expected in any web-based application and API service. This includes both frontend (web app) and backend (API/service) aspects:

1. User Authentication & Authorization

  • Login/Signup
  • Forgot password / Reset password
  • Role-based access control

2. Dashboard or Landing Page

  • Overview of key metrics/data
  • Navigation to core functionalities

3. User Management

  • Profile view/edit
  • Account settings
  • Admin can manage users (for B2B/SaaS apps)

4. CRUD Operations

  • Create, Read, Update, Delete for core data objects
  • Pagination, filt ering, and sorting on lists

5. Responsive UI

  • Mobile-friendly layouts
  • Accessibility considerations

6. Notifications

  • Toast alerts (success, error, warning)
  • In-app notifications (optional)
  • Email alerts (optional)

7. Search and Filter

  • Global search or contextual search
  • Multi-criteria filters

8. Audit & Activity Logs

  • Track what users do (especially for admin or regulated apps)

9. Security Features

  • CSRF/XSS protection
  • HTTPS, secure cookies
  • CAPTCH
  • A / 2FA (for enhanced security)

10. Internationalization (i18n)

  • Multi-language support (if required)

**

Common Features in Any API Service

**

1. RESTful or GraphQL APIs

  • Standardized endpoints
  • Proper HTTP status codes

2. Authentication & Authorization

  • Token-based (JWT, OAuth2, API keys)
  • Role-based access for endpoints

3. Rate Limiting & Throttling

  • Prevent abuse
  • API tiering for monetized platforms

Validation

  • Input validation (schemas, DTOs)
  • Error handling with structured responses

5. Logging & Monitoring

  • Structured logs (JSON)
  • Integration with monitoring tools (e.g., Prometheus, ELK, Datadog)

6. Versioning

  • /api/v1/ style or header-based API versioning

7. Health Check Endpoint

  • /health, /ping, or /status endpoint to indicate service status

8. CORS Configuration

  • Allow cross-origin requests as needed

9. Testing & Documentation

  • Swagger/OpenAPI documentation
  • Postman collections
  • Automated tests (unit/integration)

10. Database & Caching

  • DB connection pooling
  • Caching using Redis or similar (for frequently accessed data)

Next: I will comes up with implementation of User Authentication & Authorization in ASP.NET Core (.NET 7 or later)
