Azure Blob Storage get file list from specific directory not from container

I have created code to getting the files list from the Azure blob container.

const sharedKeyCredential = new StorageSharedKeyCredential(account, accountKey);

 const containerName = `newcontainer${new Date().getTime()}`;
  const containerClient = new ContainerClient(
    `https://${account}.blob.core.windows.net/${containerName}`,
    sharedKeyCredential
  );


 console.log("Listing all blobs");
  i = 1;
  for await (const blob of containerClient.listBlobsFlat()) {
    console.log(`Blob ${i++}: ${blob.name}`);
  }

above code return list of all files. but in my container, there are two folders one is IN folder and the second is OUT folder. I just need only the files list from IN folder.

is that any function available to get a list from a specific directory?

Just add prefix option in your listBlobsFlat method and you will be able to list blobs from IN folder only. Something like:

for await (const blob of containerClient.listBlobsFlat({prefix: 'IN/'})) {
    console.log(`Blob ${i++}: ${blob.name}`);
}

You can learn more about blob listing options here: https://learn.microsoft.com/en-us/javascript/api/@azure/storage-blob/containerlistblobsoptions?view=azure-node-latest
