Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

keyv publishes both a CommonJS entry and a native ESM entry (ESM added in 5.0.0). require("keyv") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "keyv" works alongside it.

What to do

  1. Nothing to change. require("keyv") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import * as keyv from "keyv" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.

How to import keyv

ES modules (import)

import * as keyv from "keyv";

Namespace import shown because the ESM entry may have no default export; use named imports for what it exports.

CommonJS (require)

const keyv = require("keyv");

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (77 versions; the newest 60 shown).
