dropwarp

Send a file and get a shareable link in one call. Official client for the DropWarp API — no buckets, no presigned-URL dance, no storage to manage. Files are private and auto-expire.

npm i dropwarp

Quickstart

Create a free key at https://dropwarp.com/account, then:

import { DropWarp } from "dropwarp";

const dw = new DropWarp(process.env.DROPWARP_KEY);

const { downloadUrl } = await dw.send("./report.pdf");
console.log(downloadUrl); // → https://dropwarp.com/s/9f1c… (give this to anyone)

send() takes a file path (Node/Bun/Deno) or raw bytes — a Buffer, Uint8Array, Blob, or ReadableStream:

await dw.send(buffer, { filename: "photo.jpg", contentType: "image/jpeg" });
await dw.send(new Blob([data]), { filename: "data.bin" });

API

| Method | Description | | --- | --- | | dw.send(file, opts?) | Upload a file → { downloadUrl, expiresAt, … } | | dw.list() | List your stored files | | dw.remove(id) | Delete a stored file | | dw.me() | Your plan + limits | | dw.p2pToken() | Mint a room token for a live peer-to-peer transfer (advanced) |

Errors throw a DropWarpError with .status, .code, and .body.

Limits

• Free: files up to 250 MB, links live 2 hours, 50 uploads/day.
• Paid ($1/mo): files up to 5 GB, links live 30 days, unlimited uploads.

Upgrade to lift the free cap.

Runtimes

Works anywhere fetch exists — Node 18+, Bun, Deno, browsers, edge runtimes. Reading a file from a path string uses node:fs; pass bytes directly to stay fully runtime-agnostic.

Building an assistant? There's an MCP server (npx @dropwarp/mcp) that gives models like Claude a native send_file tool.
