Apache OpenDAL™ Node.js Binding

A native Node.js binding for Apache OpenDAL: access S3, GCS, Azure Blob, HDFS, the local filesystem, and 50+ more services through one API.

We release the OpenDAL Node.js binding independently of the opendal crate (Rust core). For updates and compatibility, use the Node.js binding version instead of the opendal crate version.

Installation

Quickstart

import { Operator } from "opendal";

async function main() {
  const op = new Operator("fs", { root: "/tmp" });
  await op.write("test", "Hello, World!");
  const bs = await op.read("test");
  console.log(new TextDecoder().decode(bs));
  const meta = await op.stat("test");
  console.log(`contentLength: ${meta.contentLength}`);
}

main();
Copy

The API is promise-based; every operation has a synchronous *Sync variant too. For configuring backends, streaming, layers (retry, timeout, logging, throttle, concurrency limits), presigned URLs, and Next.js usage, see the full user guide.
