  • Testing Your Hapi.js Application

    • Unit Testing
      • Writing unit tests for individual components and routes using testing frameworks (e.g., Lab, Mocha).
      • Using mock data and stubs for testing.
    • Integration Testing
      • Testing entire routes and interactions with the application.
      • Setting up test environments and using tools like Nock for HTTP mocking.

  • Error Handling and Logging

    • Global Error Handling
      • Setting up global error handlers for your application.
      • Customizing error responses and integrating with logging systems.
    • Logging
      • Integrating logging libraries (e.g., Winston, Pino).
      • Configuring logging levels and output formats.
      • Implementing centralized logging for distributed applications.

  • Caching and Performance

    • Caching Strategies
      • Using Hapi.js built-in cache mechanisms.
      • Configuring caching for routes and responses.
      • Implementing server-side caching strategies and integrating with external caching systems.
    • Performance Optimization
      • Profiling and benchmarking your Hapi.js application.
      • Techniques for improving performance, such as minimizing response time and optimizing database queries.

  • Authentication and Security

    • Authentication Strategies
      • Configuring authentication strategies: Basic, JWT, OAuth.
      • Setting up authentication strategies and registering them with Hapi.js.
    • Authorization
      • Implementing role-based access control (RBAC).
      • Securing routes and managing user permissions.
    • Security Best Practices
      • Configuring security headers: Content Security Policy (CSP), XSS Protection, etc.
      • Understanding and preventing common security vulnerabilities (e.g., CSRF, XSS).

  • Working with Plugins

    • Using Built-in Plugins
      • Overview of Hapi.js built-in plugins: inert, vision, blipp.

  • Building and Managing Routes

    • Defining Routes
      • Creating routes with different HTTP methods: GET, POST, PUT, DELETE.
      • Understanding route path parameters and query parameters.
      • Route configuration: handler, tags, auth, validate, and response.
    • Route Handlers
      • Writing handlers to process incoming requests and generate responses.
      • Accessing request data (headers, payload, query parameters) within handlers.
    • Route Validation with Joi
      • Introduction to Joi for schema validation.
      • Defining request payload and query parameter schemas.
