I agree to the digital product terms and proprietary licence, and understand this is developer source code requiring integration and testing.

01

Upload lifecycle

Initiate, direct upload, finalize, inspect, accept or reject, and signed download.

02

Validation

Server-owned policies with signature checks — browser metadata is never trusted.

03

Storage

Private S3-compatible adapter with AWS S3 and Cloudflare R2 configuration guides.

Description

Add authenticated, private file uploads with server-owned validation, explicit lifecycle states, and tests for the edge cases AI-generated implementations often miss. Developers or AI-assisted builders who already have an application and need to add or harden authenticated file uploads.

  • Server-owned upload policies and content-signature validation
  • S3-compatible storage adapter (AWS S3 and Cloudflare R2)
  • Short-lived signed upload and download handling
  • Replaceable inspection boundary with local test implementation
  • Source code: Readable TypeScript you can modify and integrate into your own project.
  • Tests: Automated tests covering the core implementation.
  • Documentation: Setup instructions, architecture explanation and usage examples.
  • Examples: Working examples showing common implementation patterns.
  • AI implementation guide: A structured specification you can give to a coding assistant to help integrate the product.
