The **esrol‑initializer** package provides a tiny framework‑style class for managing and bootstrapping application components in a defined order. Developers register component objects that include a `priority` and an initialization function (which may return a Promise), then call `instantiateComponents()` to run them sequentially and invoke a final callback once all components have resolved. It’s aimed at Node.js developers who need a simple, priority‑based loader for modular code.
