Thanks @vincentkoc for starting this! I was just looking into this myself. I started with your PR and added: - make arrow 21 the default - widen the peer range to <22 so if they release 21.3 that'll be included - have to do skipLibCheck in tsconfig.json, because of flatbuffers 25 which needs TypeScript 5.7 - fix override in Symbol.hasInstance - support new types in Arrow 20-21 (LargeList, Utf8View, BinaryView, IntervalMonthDayNano) - arrow-compat job in nodejs.yml that runs tests with arrow 19 and 20 (adds 2 sec) - put the list of arrow types in one place - update NODEJS_THIRD_PARTY_LICENSES.md - regenerated typescript docs (sorry about reorderings, one time cost) - reformat arrow.test.ts (sorry, almost all whitespace, thanks to biome. git diff -w shows 110 lines edited) - fixed Sliced Utf8View / BinaryView serialization error, by just converting them to Utf8 and Binary (as our rust code would anyway) --------- Co-authored-by: Vincent Koc <vincentkoc@ieee.org> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com>
