Review Summary
This is a strong submission that correctly implements most of the server logic, including routing and stream-based compression. Great job on that! However, one change is required before this can be approved. The way the compressed filename is constructed doesn't fully meet the requirements. Currently, it produces extensions like .gzip and .deflate, but the task specifies .gz and .dfl respectively. You can fix this in src/createServer.js by mapping the compression type to the correct extension. Also, a minor typo (reqiered instead of required) was found in src/public/index.html. Correcting the file extension logic is the main blocker here. You're very close!

The way the compressed filename is constructed doesn't fully align with the task requirements. The requirement specifies extensions .gz for gzip, .dfl for deflate, and .br for br. This implementation uses the compressionType value directly, which results in incorrect extensions like .gzip and .deflate. You should create a mapping between the compression type and its corresponding extension to generate the correct filename.

There's a typo in the required attribute. It should be spelled required for the browser to enforce that a file must be selected before submitting the form.

Review Summary
Great job fixing the typo in the HTML file! The server logic for routing and error handling is looking solid.
However, this requires changes because the main requirement for filename extensions hasn't been met yet. Currently, the server creates files like file.txt.gzip instead of the required file.txt.gz. This is happening in src/createServer.js where the compressionType is used directly to build the filename.
To fix this, you'll need to map the compression types to their correct extensions (e.g., 'gzip' to '.gz' and 'deflate' to '.dfl'). An object or a switch statement would be a great way to handle this. You're very close to completing the task!

This line still doesn't produce the correct file extensions as required by the task. For a compressionType of 'gzip', the extension should be .gz, and for 'deflate', it should be .dfl. Currently, this will result in filenames like file.txt.gzip. Consider creating a map or a switch statement to associate the compression type with the correct extension string.

Review Summary
Excellent work on this submission! I am approving your solution as you've perfectly addressed all the feedback from the previous review and met every requirement. Your use of Maps to handle the different compression types and their corresponding extensions is a very clean and effective approach. The server logic is robust, handling all success and error cases correctly, and the core requirement of using streams for compression is implemented perfectly. Great job!
