I'm using nodejs to send rest api call to azure Query Blob Contents to read csv file. I managed to get the response back, but the issue is response is in avro/binary format like below.
Here i need to extract hostname & serial. How to handle this type and get the data ? As a side note, I need to acheive this only using prebuild nodejs modules(external libs are not allowed within the platform)

You would need to write your own avro parser if no external libs are not allowed. Otherwise, there are npm packages like avro-js or avsc
