Frequently Asked Questions about Hapi
What is Hapi?
Hapi is a rich, flexible web framework for Node.js designed to build scalable and maintainable applications and services with configuration-driven architecture and powerful plugin system.
What are the primary use cases for Hapi?
REST APIs and GraphQL endpoints. Enterprise web applications. Microservices with plugin-based modularity. Secure backends with authentication/authorization. Server-side rendering and templating
What are the strengths of Hapi?
Highly modular and configurable. Strong focus on security and input validation. Scales well for large, enterprise apps. Plugin ecosystem simplifies adding features. Well-documented and supported by active community
What are the limitations of Hapi?
Requires understanding of Node.js and Hapi lifecycle. Steeper learning curve compared to Express. Less lightweight than minimal frameworks like Fastify. Smaller ecosystem than Express. Can feel verbose for simple apps
