Changes:

  • Replaced usage of fstream with fs-extra.
  • Updated packages to remove and replace vulnerable dependencies

Thanks @AyushAher, please ensure PR is passing all tests before I can review it. Also please submit PR without style changes for now, only the material code changes required for the replacement library.

@AyushAher tests are still failing (eslint). Please ensure all tests pass by either running locally or by running github actions on your fork.

Also, please remove the axios code into a separate PR if you want to submit that code. We should not "replace" url source but instead create a new one called axios and also update readme

Removing all node versions except 19.x significantly reduces coverage and does not make sense. PLan is to have test coverage across node versions at least mirror exceljs

This code is not efficient, as it will create an empty file and then subsequently overwrite it with the createWriteStream. It's better to just focus on the directory, not the file.

As discussed, axios can not be part of this PR. You can submit a second PR but please do axios as a new source instead of replacing functionality. Backwards compatibility matters

You can't pass the tests by simply changing the expected test outcome. This check ensures that what you end up extracting exactly mirrors the underlying archive. If successful, differences should be zero.

normalize should not be required on linux/mac. Is this a windows issue?

ZJONSSON commented Jun 8, 2024

@AyushAher thank you for actively participating. Your idea of using fs-extra has been implemented here: #318

I'm closing this PR because of the following issues:

  • You are removing all node versions from tests except version 19
  • You are changing tests so that they pass when there are differences between extracted files and the contents of the archive
  • You are using fs.ensureFile, which creates an empty file and is not as efficient as fs.ensureDirectory
  • Axios should not be part of this PR

Thanks again! If you want to pursue Axios, please do so as a separate source (i.e. url should use request and axios should use axios etc).
