v4.3.0

Features

  • Add opt-in skipEmptyLines to the parser, validateFile, TypeScript options and CLI. Empty and whitespace-only unquoted records are skipped without dropping quoted blanks or delimiter-only records; existing defaults are unchanged.

Improvements

  • Assemble fragmented records once instead of repeatedly copying their growing prefix.
  • Honor readable backpressure within input chunks and release parser-owned final-record references at EOF. Memory still depends on the current record, input chunk and caller-retained raw buffers; performance varies by workload.

Bugfixes

  • Recognize complete comment markers before CSV quotes, including Unicode markers split across chunks.
  • Terminate on strict width errors and reject colliding overflow row keys instead of losing values.
  • Correct CLI handling of strict mode, removed columns, custom quotes and escapes, bare/custom comment markers, and stream failures. For a bare comment flag with file input, use csv-parser input.csv --skipComments; a following value remains a custom marker.
  • Make the checkout benchmark count rows without retaining them and await pipeline completion.

Native ESM, the Node.js requirement (^22.22.2 || >=24.15.0) and zero runtime dependencies are unchanged. Data Loader consumer adoption remains separate and deferred.
