Review Summary
Great work on implementing the server and handling file compression with streams! The core logic is solid. However, there are a couple of specific requirements from the task description that need to be addressed before this can be approved.
First, the HTML form uses a text <input> for the compression type. This needs to be changed to a <select> element with <option> tags for gzip, deflate, and br.
Second, the compressed file extension is incorrect. The server should produce files with extensions like .gz for gzip and .dfl for deflate, rather than using the full compression type name. You'll need to map the selected compression type to its corresponding extension in the content-disposition header.
You're very close to a complete solution! Please make these adjustments and resubmit.

The task requires a <select> field for choosing the compression type, not a text input. This field should have gzip, deflate, and br as its options.

The file extension for the compressed file does not match the requirement. The task specifies that for the gzip compression type, the extension should be .gz, and for deflate it should be .dfl. A mapping is needed to generate the correct file extensions.

Review Summary
Great job updating the form to use a <select> element for the compression type! The server logic is well-structured. However, this submission requires a change because the compressed file naming doesn't meet the project requirements. Currently, the server creates filenames using the full compression type, like my-file.txt.gzip instead of the required my-file.txt.gz. To fix this, you'll need to create a mapping from the compression type (gzip, deflate) to the correct file extension (.gz, .dfl). For example:
const extensions = {
gzip: 'gz',
deflate: 'dfl',
br: 'br',
};Once that's implemented, this will be ready for approval!

The file extension for the compressed file is not quite right. According to the requirements, gzip should result in a .gz extension and deflate should result in a .dfl extension. Currently, you're using the full compression type name from the form, which only works for br. You'll need to create a mapping from the compression type to the correct file extension.

Review Summary
Excellent work on this task! You've successfully addressed the previous feedback by implementing the correct file extensions for compressed files. Your server implementation is robust, making great use of streams and the zlib module to handle uploads and compression. All requirements, including the various success and error cases, have been met perfectly. The code is clean and well-structured, and I'm happy to approve this solution.
