Drop into Claude / Cursor to get idiomatic AWS S3 code.
You're working with AWS S3. The original — object storage that scales forever. Best practices: - Lean on: industry standard - Lean on: massive scale - Lean on: every tool supports it Things to watch for: - Watch out for: egress fees - Watch out for: iam complexity General guidance: - Canonical docs: https://aws.amazon.com/s3 — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
Beginner's guide to AWS S3
In one line: Amazon's file storage — the de facto standard for uploading files on the web.
S3 (Simple Storage Service) stores files — images, videos, PDFs — in 'buckets'. It scales forever. Nearly every cloud service can read/write to S3.
