Question 1

How does WAFer compare to Node.js for web servers?

Accepted Answer

WAFer offers similar event-driven scalability but in C, with a much smaller memory footprint and direct system control. However, it lacks Node.js's npm ecosystem and JavaScript ease, making it better for performance-critical C applications where minimal overhead is key.

Question 2

Can I use WAFer to build a REST API in C?

Accepted Answer

Yes, WAFer can handle REST APIs, but you'll need to manually implement HTTP parsing, routing, and JSON serialization in your server.c file. The minimalist design gives full control, but it requires more coding effort compared to higher-level frameworks.

Question 3

How to handle static files with WAFer?

Accepted Answer

WAFer doesn't include built-in static file serving. You must implement it in server.c by reading files from disk and sending appropriate HTTP responses, which involves manual error handling and MIME type management, as hinted by the lack of examples in the README.

Question 4

Is WAFer production-ready for high-traffic websites?

Accepted Answer

With C10K mode and configurable event loops, WAFer can handle high concurrency, but production readiness depends on your implementation. It's stable for basic use, but you're responsible for ensuring robustness, security, and performance tuning, as noted in its minimalist philosophy.

Question 5

How to set up multi-threading in WAFer?

Accepted Answer

Compile with THREADS=n where n>0 in the make command, as specified in the README. This enables multi-threaded operation, but thread management, synchronization, and workload distribution must be handled by the developer in the server.c code.

Question 6

Does WAFer support WebSockets or HTTP/2?

Accepted Answer

No, WAFer is minimalist and doesn't support WebSockets or HTTP/2 out of the box. You would need to implement these protocols yourself in C if required, which adds complexity compared to frameworks with built-in support.
