Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too
@emnapi/core publishes both a CommonJS entry and a native ESM entry (ESM added in 0.31.0). require("@emnapi/core") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "@emnapi/core" works alongside it.
What to do
- Nothing to change. require("@emnapi/core") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import * as core from "@emnapi/core" works alongside it; use named imports for what the ESM entry exports.
- TypeScript: types are bundled; install nothing extra.
