Download files (Node.js SDK)-Object Storage Service(OSS)-阿里云帮助中心

The OSS Node.js SDK supports several methods to download files. Choose a download method based on your scenario:

To download a file to a local file or to local memory, see Download to a local file (Node.js SDK) and Download to local memory (Node.js SDK).
To process data incrementally as a file downloads, use a streaming download. For more information, see Streaming download (Node.js SDK).
To download only part of a file, use a range download. For more information, see Range download (Browser.js SDK).
To restrict a download based on specific conditions, use a conditional download. For example, you can download only files modified before a specific time or files that match a specific ETag. For more information, see Conditional download (Browser.js SDK).
