Thank you for your hard work on this project! While your implementation meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:
-
Import Statement Issue: The import statement in
index.jsis attempting to import fromcreateServer.ts, which seems incorrect since the file extension should be.js. Please ensure that the file path and extension are correct. -
Multipart Form Data Handling: The current method of extracting file content from multipart data is not robust. It's recommended to use a library specifically designed for parsing multipart form data to enhance reliability and security.
-
Validation of Required Fields: While you have checks for missing required fields, it would be more robust to validate these fields immediately after parsing the multipart data.
-
Boundary Extraction: The regular expression used to extract the boundary from the 'Content-Type' header assumes the boundary is always present and correctly formatted. Please add a check to ensure the 'Content-Type' header exists and contains a boundary before attempting to match it.
Addressing these issues will significantly improve the robustness and security of your code. Keep up the great work, and I'm confident you'll have this polished in no time! 😊

The check for missing required fields (compressionType and fileName) is good, but it would be more robust to validate these fields earlier in the process. Consider validating the presence of these fields immediately after parsing the multipart data.

The check for file content being empty is crucial, but the way file content is extracted from the multipart data is not very robust. Consider using a library designed for parsing multipart form data to handle this more reliably and securely.

When an unsupported compression type is encountered, the response message 'Unsupported compression type' is clear, but it might be helpful to log the unsupported type for debugging purposes.

The import statement is attempting to import from createServer.ts, which seems incorrect since the file extension should be .js based on the provided files. Ensure that the file path and extension are correct.

Review Summary
Great job on implementing the basic HTTP server with functionality to serve static files and handle file uploads with compression! 🎉 Your code meets the task requirements and constraints effectively, and the import statement issue in index.js has been resolved. Here are some important points and suggestions for improvement:
-
Multipart Form Data Handling: You've chosen the
busboylibrary, which is a robust solution for handling file uploads. Ensure that it correctly manages all edge cases, such as large file uploads and various content types. -
Validation of Required Fields: The validation of required fields (
fileBuffer,compressionType, andfileName) is done after parsing, which is a good practice. However, make sure these checks are comprehensive and cover all necessary fields. -
Error Handling: While basic error handling is in place, consider providing more detailed error messages or logging to help with debugging and provide better feedback to the user.
-
Content-Type Check: The check for 'Content-Type' ensures that the header exists and contains 'multipart/form-data'. This is correctly implemented, but be sure to handle cases where the header might be malformed.
Your implementation is on the right track, and the decision to approve is made to help you move forward with your learning. Please review the comments to improve your code further. Addressing these issues will help you avoid similar problems in the future. Keep up the good work and continue learning from your experiences! 🚀
