Packages

Official SDKs

Reupload ships official packages for server and browser integrators. Use them together or pick only what you need — each layer builds on the one below.

Server SDKs

  1. @reupload/sdk — Node.js 20+ server SDK. Holds your API key and talks to the Reupload API (sessions, direct upload, files, framework route helpers).
  2. reupload-sdk (reupload-sdk) — Python 3.10+ server SDK with the same API surface, sync/async clients, and optional FastAPI helpers.

Browser SDKs (npm)

  1. @reupload/client — Browser client for your backend file router (prepare → CDN PUT → complete). No API key in the front end.
  2. @reupload/react — Drop-in React uploaders (DropzoneUploader, AvatarUploader, etc.) built on @reupload/client.

Which package do I need?

ScenarioPackages
Node API only (no custom UI)@reupload/sdk
Python API only (FastAPI, Django, scripts)reupload-sdk, Django guide
Custom React/Vite UI, your own components@reupload/sdk + @reupload/client
React app, want ready-made upload widgets@reupload/sdk + @reupload/react (includes client)
Python + React front end (CDN flow)reupload-sdk on the server + @reupload/client or @reupload/react in the browser
Server direct upload (browser → your API → Reupload)@reupload/sdk or reupload-sdk on the server only
CDN flow (browser PUTs to signed URL)Server SDK + @reupload/client or @reupload/react

Install

terminal
# Node server
npm install @reupload/sdk
 
# Python server
pip install reupload-sdk
pip install "reupload-sdk[fastapi]"   # optional FastAPI helpers
 
# Browser (CDN flow via your API)
npm install @reupload/client
 
# React uploaders
npm install @reupload/react @reupload/client

Typical CDN integration

  1. Implement POST /uploads/prepare and POST /uploads/complete with @reupload/sdk or reupload-sdk (see React/Next + Node.js).
  2. Set NEXT_PUBLIC_API_URL or VITE_API_URL in your front end.
  3. Use @reupload/react uploaders or @reupload/client in your UI.
  4. Add upload CORS origins for browser PUTs — Browser uploads.
