Needs a method to determine if no batches, or all batches are empty

[turntayble81]

I have a use case where I don't want to generate a file if there are no batches, or all batches have 0 entries. I created the following code to do this, but it would be better added to this project:

const entryCount = (this.file._batches || []).map((batch) => {
    return (batch._entries || []).length;
}).reduce((acc, val) => {
    return acc + val;
}, 0);
