Object Storage Service (OSS) SDK for Node.js provides a variety of methods to download objects. You can choose the most suitable method based on your business requirements.
For information about how to download objects to your local device or the local memory, see Download objects as files and Download objects to the local memory.
You can use streaming download to process data incrementally as it arrives during the download. For more information, see Streaming download.
You can use range download to download a specific byte range from an object. For more information, see Range download.
You can use conditional download to download objects that meet multiple specified conditions. For example, you can specify conditions to download only objects that are last modified before the specified time or objects whose Etags match the specified values.
