rajsite opened a new issue, #63: URL: https://github.com/apache/arrow-js/issues/63
### Describe the enhancement requested Currently the apache-arrow library has circular dependencies which cause warnings in tools like rollup: ``` src/example.js → dist/example.js... (!) Circular dependencies node_modules/apache-arrow/vector.mjs -> node_modules/apache-arrow/util/vector.mjs -> node_modules/apache-arrow/vector.mjs node_modules/apache-arrow/vector.mjs -> node_modules/apache-arrow/util/vector.mjs -> node_modules/apache-arrow/row/map.mjs -> node_modules/apache-arrow/vector.mjs node_modules/apache-arrow/vector.mjs -> node_modules/apache-arrow/util/vector.mjs -> node_modules/apache-arrow/row/map.mjs -> node_modules/apache-arrow/visitor/get.mjs -> node_modules/apache-arrow/vector.mjs ...and 10 more created dist/example.js in 890ms ``` See the following stackblitz which reproduces that build warning: https://stackblitz.com/edit/apache-arrow-circular-dependencies?file=src%2Fexample.js It would be nice if the library was organized such that circular dependencies could be avoided. To workaround the warnings in rollup one can use an [onwarn](https://rollupjs.org/configuration-options/#onwarn) handler in the rollup configuration with an implementation like: ```js const onwarn = (warning, defaultHandler) => { const ignoredWarnings = [ { code: 'CIRCULAR_DEPENDENCY', file: 'node_modules/apache-arrow' } ]; if ( !ignoredWarnings.some( ({ code, file }) => warning.code === code && warning.message.includes(file) ) ) { defaultHandler(warning); } }; ``` ### Component(s) JavaScript -- This is an automated message from the Apache Git Service.
