[AnsonChung3]

Summary/Description/Done changes

Add backend functionality to convert pdf/docx/txt into plain text.
This branch includes a demo test page, please do give it a try and let me know if it doesn't work as intended.
Extra packages are installed for parser. Please do npm i when you check out this branch or after this branch is merge into main.

Please delete this branch after merging. Thanks. 😄 🍻

Known issues (if any)

1. parser does not accept .doc file

• .doc is a binary file while .docx is an openXML file. They are very different in nature. Trying to parse .doc file is a sizeable task in itself. It can be added if we have enough time.

2. the server endpoint is not inside the correct module

• This is intentional and temporary. It can be fixed after integration test.

Time spent on this issue

Total time: 6hr 30min

• initial run time error gave no information
• time took to find out the error log option
• unexpected typescript problem such as import syntax, import types, and types
• package for pdf parsing didn't work as expected:
  • expected: package can be called as a function
  • actual implementation: package is imported as a class, to perform task, I had to go inside the package file to find out the class function that can be called

Tested the /upload-cv endpoint on Postman and all file parsing (PDF, DOCX, TXT) works correctly
