The **bit‑loader‑cache** package is a plug‑in for the **bit‑loader** (used with bit‑bundler) that caches module build results to speed up subsequent builds. It stores the cache locally by default but can be configured with custom “connectors” (e.g., Elasticsearch or Redis) and offers options for cache file location and write‑throttling, making it useful for developers who need faster rebuilds in Bit‑based JavaScript projects.
