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

safe-stable-stringify publishes both a CommonJS entry and a native ESM entry (ESM added in 2.0.0). require("safe-stable-stringify") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=10. import "safe-stable-stringify" works alongside it.

What to do

  1. Nothing to change. require("safe-stable-stringify") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=10. import * as safeStableStringify from "safe-stable-stringify" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
