Parsing ByteBuffer in node? - node.js

Question

I have data from an api that has returned like this:
var body = data;
data is equal to:
ByteBuffer {
buffer:
<Buffer 09 62 61 1f 04 01 00 10 01 11 61 99 5d 05 01 00 10 01>,
offset: 0,
markedOffset: -1,
limit: 18,
littleEndian: true,
noAssert: false
}
I've tried passing different functions to it to try to get the data from it. (I'm expecting at least 2 IDs.) Here is what I have tried so far and their results:
var message = body.readUint32(); // 526475785
var message = body.readCString(); // [blank]
var message = body.readUint8(); // 16
var message = body.readUint64(); // Long { low: -1721691903, high: 66909, unsigned: true }
I also tried:
var message = new ByteBuffer(8 + 8 + 4 + Buffer.byteLength(body.buffer) + 1, ByteBuffer.LITTLE_ENDIAN);
which returned:
ByteBuffer {
buffer:
<Buffer 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00>,
offset: 0,
markedOffset: -1,
limit: 39,
littleEndian: true,
noAssert: false
}
I also tried passing just 'body' in but that didn't work at all. Should I be parsing this differently? What exactly should I change to get the data? Thank you

You have to flip the bytebuffer first to make the ByteBuffer ready for read operations.
After the buffer is ready for read operations, use readIString to read the whole buffer as a string, you can use other operations such as readInt32 if you are expecting the buffer to be of other values than a string (I'm assuming a string since it is coming from an API).
body.flip().readIString();
