ESM-only ESM-only — it has never shipped a CommonJS build
tinyrainbow has been ESM-only since its first stable release. There is no version you can require() on Node.js 18 or older.
On Node.js 20.19+, 22.12+ and every newer release, require("tinyrainbow") works anyway: Node can load synchronous ES modules through require(). Verified on Node 20, 22, 24, 26. Node.js 18 and older still fail with ERR_REQUIRE_ESM.
