Review Summary

Your solution is approved because it implements all required Compression App features correctly: the HTML form at / has the proper file input and compressionType select (gzip, deflate, br), and POST /compress returns a compressed file stream with the correct extension and appropriate 200/400/404 status codes. The server correctly uses Node.js streams and zlib to pipe the uploaded file through the chosen compressor to the response, which matches the task’s streaming requirement. To make the implementation more robust, consider adding .on('error', ...) handlers to the file read stream and compression stream in src/createServer.js (around the fs.createReadStream and zlib.createGzip/Deflate/BrotliCompress pipeline) so that unexpected I/O or compression failures return a 500 instead of potentially crashing the server. It would also be an improvement to explicitly set Content-Type: application/octet-stream and to quote/escape the filename in the Content-Disposition header so that filenames with spaces or special characters are handled reliably by browsers. These are refinements rather than correctness issues, and overall your implementation is clear, concise, and meets the functional requirements well. Nice work applying streams and zlib effectively in this small but realistic server.
