ithkuil/json-update

This tiny npm module (`json‑update`) lets you create or modify a JSON file in a single line of code, merging new properties into an existing file (or creating the file and any missing directory structure) and returning the updated object. It works with simple callbacks, Promise/async‑await, and optionally deep‑merges data, making it handy for developers who need straightforward, file‑based persistence for configs, state, or small JSON‑driven utilities in Node.js applications.
