Thank you for your hard work on this project! 😊 While your server implementation is solid and meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request. The most important issue is the missing HTML form implementation, which is a core requirement of the task. Additionally, there are potential runtime errors related to the handling of compressionType and file from the form data. Please ensure these elements are correctly accessed and validated to prevent errors. Once these issues are resolved, your solution will be much stronger. Keep up the great work, and I'm confident you'll nail it with the next iteration! 🚀

The destructuring of compressionType and file from the parsed form data might not work as expected if the form fields are not named exactly as assumed. Ensure that the form fields are correctly named and that compressionType and file are accessed correctly.

The condition !file || !compressionType might not be sufficient if file or compressionType are arrays or objects. Consider checking if file[0] and compressionType[0] exist and are valid.

Ensure that file[0] is a valid object with the expected properties. If file is not an array, this line will cause an error.

The compressionType[0] is used directly. Ensure that compressionType is an array and has at least one element to avoid runtime errors.

Review Summary
Great effort on implementing the server functionality! 🎉 Your code is mostly on the right track, but there are a few critical issues that need attention:
-
Missing HTML Form Implementation: The task requires an HTML form for users to select a file, choose a compression type, and submit it to the server. This is a core requirement and currently missing. Adding this form will complete the user interaction part of your project.
-
Handling of
compressionTypeandfile: Your server code increateServer.jsdoes a good job of validating thecompressionTypeandfile. However, ensure that you handle cases where these are missing or invalid to prevent runtime errors. -
Response Headers: Consider adding a
Content-Typeheader to the response to ensure that the client handles the file download correctly. You can set it usingres.setHeader('Content-Type', 'application/octet-stream');. -
Server Implementation: The server correctly handles streams and uses the
zlibmodule for file compression. It also responds with appropriate status codes for various scenarios, which is well done.
The decision to approve is made to help you move forward with your learning. Please review the comments and address the critical issues, especially the missing HTML form, to enhance your solution. Keep up the good work and continue improving your code! 🚀

Consider adding a Content-Type header to the response to ensure that the client handles the file download correctly. This can be done by setting res.setHeader('Content-Type', 'application/octet-stream');.
