Even if you do not plan to contribute to Apache Arrow itself or Arrow integrations in other projects, we'd be happy to have you involved:
We prefer to receive contributions in the form of GitHub pull requests. Please send pull requests against the github.com/apache/arrow repository.
If you are looking for some ideas on what to contribute, check out the JIRA issues for the Apache Arrow project. Comment on the issue and/or contact dev@arrow.apache.org with your questions and ideas.
If you’d like to report a bug but don’t have time to fix it, you can still post it on JIRA, or email the mailing list dev@arrow.apache.org

- cleans targetsnpm run build
- cleans and compiles all targetsnpm test
- executes tests against built targetsThese npm scripts accept argument lists of targets × modules:

, es2015
, esnext
, and all
(default: all
)modules
are cjs
, esm
, umd
, and all
(default: all
)Examples:
npm run build
-- builds all ES targets in all module formatsnpm run build -- -t es5 -m all
-- builds the ES5 target in all module formatsnpm run build -- -t all -m cjs
-- builds all ES targets in the CommonJS module formatnpm run build -- --targets es5 es2015 -m all
-- builds the ES5 and ES2015 targets in all module formatsnpm run build -- -t es5 --modules cjs esm
-- builds the ES5 target in CommonJS and ESModules module formatsThis argument configuration also applies to clean
and test
