Asked 2021-Apr-06 at 07:26

I am extremely new to NodeJS and promises, after a google search found the code below and made it into a promise to read a CSV file using fast-csv, create an array of the data based on the packNr. The below code is spliting the files as expected but my issue is writing the array back to a new CSV file. Somehow I need to finish writing each packNr before the next one begins. Using the code below I only get the header of each file to write before the code completes.

Answered 2021-Apr-06 at 01:49

I think the problem is that fastCsv.write is itself asynchronous, so of course the resolve() is executing before it completes. I believe the answer is to wait until the fastCsv.write() completes before resolving.

I found out why It was not fully processed, it's because the callback of batchWriteItem can return unprocess Items. So I change the function batchWrite and also the runPromiseStreamAsync a little bit because i might not have all the items processed from itemsToProcess.
