Code SnippetScheduled for 13 September 2026

![Upload Files to AWS S3 with Pre-Signed URLs in Node.js](/_astro/hero.DybygcPa_JGWlc.webp)

A Node.js snippet for generating S3 pre-signed URLs so clients upload straight to S3 instead of through your server. Covers PUT URL generation, expiry, content-type and size enforcement, CORS, multipart for large files, and the IAM policy that keeps it scoped.
