Streaming file downloads is essential for Node.js applications serving large files efficiently without consuming excessive memory. As the creator of CoreUI with over 11 years of Node.js development experience since 2014, I’ve optimized file serving in numerous enterprise applications. The most effective solution is to use Node.js streams with createReadStream to pipe files directly to the response. This approach handles files of any size efficiently while maintaining low memory usage.

Enabling file downloads is a common requirement in Vue applications, from exporting reports to downloading user-generated content. As the creator of CoreUI with over 11 years of Vue development experience since 2014, I’ve implemented file download functionality in numerous production applications. The most effective solution is to create a blob URL and trigger the download programmatically using an anchor element. This approach works for both API-fetched files and client-generated content.
