Implement JWT Provider

[rsaz]

Description

This task involves creating a JWT (JSON Web Token) Provider within the ExpressoTS framework. The provider will be responsible for generating, verifying, and managing JWTs, which are critical for secure authentication and authorization processes. While jsonwebtoken is suggested, the developer is encouraged to evaluate and propose any superior alternatives.

Goals

• Secure Token Management: The JWT provider should ensure tokens are generated and managed securely, incorporating best practices to prevent common security vulnerabilities.
• Ease of Use: It should offer a simple and straightforward interface for other components within the framework to generate and verify tokens.
• Flexibility: The provider must be configurable to accommodate different use cases and security requirements.

Requirements

Provider Setup:

• Evaluate the jsonwebtoken library and any other potential libraries for JWT management. Select the most suitable option based on features, security, performance, and community support.
• Create a new provider class that adheres to the IProvider interface from the ExpressoTS core.

Token Generation:

• Implement a method for generating JWTs with support for custom claims and expiration settings.
• Ensure the generation process is compliant with the latest security standards for token-based authentication.

Token Verification:

• Provide a method for verifying JWTs, including signature validation and claim checks.
• Handle common JWT verification issues gracefully, providing meaningful error messages.

Configuration:

• Allow for easy configuration of token secret keys, algorithm selection, and other JWT settings through environment variables or configuration files.

Testing:

• Develop a comprehensive test suite to verify token generation, expiration, signature validation, and error handling.
• Include tests for different configuration scenarios to ensure flexibility and robustness.

Documentation:

• Document the provider’s methods, configurations, and usage within the ExpressoTS framework.
• Provide sample code and use-case scenarios to guide developers on how to utilize the JWT provider for authentication and authorization.

Integration:

• Ensure the provider integrates seamlessly with the ExpressoTS authentication and authorization mechanisms.
• The JWT provider should be easy to plug into existing applications built on the ExpressoTS framework with minimal configuration.

Deliverables

• A fully implemented JWT provider compatible with the ExpressoTS framework.
• A detailed report comparing jsonwebtoken with any other evaluated libraries, justifying the selection.
• A test suite covering all aspects of the JWT provider.
• Comprehensive documentation and usage examples.
