Review Summary
Great job setting up the server and implementing the core compression logic using streams and the zlib module! Your code handles most of the routing requirements correctly. However, a couple of critical issues need to be addressed before this can be approved. Here are the required changes:
- Server Stability: The application currently crashes if a POST request is sent to
/compresswithout a validcontent-typeheader. You should add a check to ensure the header exists and is well-formed before trying to parse it. If it's invalid, the server should respond with a 400 status code as per the requirements. - File Naming: The compressed files are being saved with incorrect extensions. The task requires
.gzforgzipand.dflfordeflate, but your code is generating.gzipand.deflate. Please map the compression types to their correct, shorter extensions.
Once these issues are fixed, your solution will be in great shape. Keep up the good work!

The application could crash if the 'content-type' header is missing or doesn't contain a boundary. It's important to validate the header before attempting to access its properties. According to the requirements, the server should handle this as an invalid form submission and respond with a 400 status code.

The task description requires the file extensions to be .gz, .dfl, and .br for gzip, deflate, and br compression types respectively. This line appends the full compression type name as the extension, resulting in incorrect extensions like .gzip and .deflate. You should map the compression type to the correct file extension.

Review Summary
Excellent work! I am approving your solution as you've successfully addressed all the feedback from the previous review and met all the task requirements. The server now correctly handles the content-type header and uses the proper file extensions for compressed files. Your implementation of Node.js streams and the zlib module is solid and the code is clean. Great job!
