Summary

  • Update all CSV download/reader components to use new utilities
  • Update tests to mock the new utilities
  • Remove react-papaparse dependency, add papaparse and @types/papaparse

Files Changed

  • web/utils/csv.ts - New CSV utility functions
  • web/app/components/share/text-generation/run-batch/csv-download/index.tsx
  • web/app/components/share/text-generation/run-batch/csv-reader/index.tsx
  • web/app/components/share/text-generation/run-batch/res-download/index.tsx
  • web/app/components/app/annotation/header-opts/index.tsx
  • web/app/components/app/annotation/batch-add-annotation-modal/csv-downloader.tsx
  • web/app/components/datasets/documents/detail/batch-modal/csv-downloader.tsx
  • Updated corresponding test files
