Node.js & Amazon S3: How to iterate through all files in a bucket?

Question

Is there any Amazon S3 client library for Node.js that allows listing of all files in S3 bucket?

The most known aws2js and knox don\'t seem to have this functionalit

Answer 1

I am using this version with async/await.
This function will return the content in an array.
I'm also using the NextContinuationToken instead of the Marker.

async function getFilesRecursivelySub(param) {

    // Call the function to get list of items from S3.
    let result = await s3.listObjectsV2(param).promise();

    if(!result.IsTruncated) {
        // Recursive terminating condition.
        return result.Contents;
    } else {
        // Recurse it if results are truncated.
        param.ContinuationToken = result.NextContinuationToken;
        return result.Contents.concat(await getFilesRecursivelySub(param));
    }
}

async function getFilesRecursively() {

    let param = {
        Bucket: 'YOUR_BUCKET_NAME'
        // Can add more parameters here.
    };

    return await getFilesRecursivelySub(param);
}
