Review Summary
Great job on the overall implementation! You've correctly used streams and the zlib module to handle file compression, and the server routing is well-structured.
However, I'm requesting a change because the compressed file names do not match the task requirements. The server is currently generating files with extensions like .gzip and .deflate. The specification requires abbreviated extensions: .gz for gzip and .dfl for deflate.
You can fix this in src/createServer.js by creating a mapping from the compressionType value to the correct file extension when setting the Content-Disposition header.
Once that's updated, your solution will be complete. Keep up the excellent work!

According to the task description, the file extensions should be .gz for gzip and .dfl for deflate. Currently, the compressionType value is used directly, which results in .gzip and .deflate extensions. Consider creating a mapping from the compression type to the correct file extension.

Review Summary
Excellent work on the server structure and the use of streams. However, this submission requires changes because the main issue from the previous review regarding file extensions has not been addressed. The task has very specific requirements for the compressed file extensions.
Specifically:
gzipcompression must result in a.gzfile extension.deflatecompression must result in a.dflfile extension.
Please update the compressionExtensions object in src/createServer.js to use these correct values. Once you've made that fix, your solution will be complete!

The task requires the file extension for gzip compression to be .gz. This value should be updated to match the requirement.

According to the task description, the file extension for deflate compression should be .dfl.

Review Summary
Excellent work on this task! I am approving your solution because you've successfully addressed all the feedback from the previous review and implemented the server logic perfectly. Your use of Node.js streams with pipeline is spot-on, and the handling of different compression types with the correct file extensions (.gz, .dfl, .br) is exactly what was required. The server correctly handles all routes and error conditions as specified. This is a complete and robust solution. Keep up the great work!
