[QUESTION] how to make .c a stream.Readble

[nunuqq1]

minio can upload a readable stream, using minioClient.putObject('xxx', 'yyy.tar', someReadableStream) so how to transform the return value of tar.c() to a readable stream?

It already does return a readable stream: https://github.com/npm/node-tar/blob/main/lib/create.js#L100-L104

Pack is a readable stream. https://github.com/npm/node-tar/blob/main/lib/pack.js#L3

const tarReadableStream = tar.c({ gzip: false, basename: true }, ['./']) const putRet = await minioClient.putObject('xxx', 'yyy.tar', someReadableStream)

error TypeError: third argument should be of type "stream.Readable" or "Buffer" or "string"

function isReadableStream(arg) { return isObject(arg) && isFunction(arg._read); } // check if arg is boolean

minio use the code above to check

It's not an internal node readable stream it's a minipass stream. Because of that you may have to pipe it to another internal node stream to get other software that is expecting specific data types to work.

Or you can open up an issue w/ minio to ask them to support minpass streams.
