Using KV in Node.js

Connecting to a Deno KV database in Node.js is supported via our official client library on npm. You can find usage instructions for this option below.

Installation and usage Jump to heading#

Use your preferred npm client to install the client library for Node.js using one of the commands below.

npm install @deno/kv 

pnpm add @deno/kv 

yarn add @deno/kv 

Once you've added the package to your Node project, you can import the openKv function (supports both ESM import and CJS require-based usage):

import { openKv } from "@deno/kv"; // Connect to a KV instance const kv = await openKv("<KV Connect URL>"); // Write some data await kv.set(["users", "alice"], { name: "Alice" }); // Read it back const result = await kv.get(["users", "alice"]); console.log(result.value); // { name: "Alice" } 

By default, the access token used for authentication comes from the DENO_KV_ACCESS_TOKEN environment variable. You can also pass it explicitly:

import { openKv } from "@deno/kv"; const kv = await openKv("<KV Connect URL>", { accessToken: myToken }); 

Once your Deno KV client is initialized, the same API available in Deno may be used in Node as well.

KV Connect URLs Jump to heading#

Connecting to a KV database outside of Deno requires a KV Connect URL. A KV Connect URL for a database hosted on Deno Deploy will be in this format: https://api.deno.com/databases/<database-id>/connect.

The database-id for your project can be found in the Deno Deploy dashboard, under the project's "KV" tab.
