A tiny add-on to autoload your initializer files in ember-cli.

Last verified Sep 9, 2026 against ember-load-initializers@3.0.1. JSON

ESM-only ESM-only since 3.0.0 — last CommonJS version is 2.1.2

ember-load-initializers dropped its CommonJS build in 3.0.0 (September 2024). The last version you can require() on every Node.js version, including 18 and older, is 2.1.2, published Nov 6, 2020.

On Node.js 20.19+, 22.12+ and every newer release, require("ember-load-initializers") 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.
