enmap-json-sync v1.1.6

Enmap-JSON-Sync

This package allows you to use most of the normal JS Map functions but in the background automatically persists your data to a JSON file. I created this project because I just wanted a simple way to create key pair values and have them automatically save to a file without needing to download and setup a bunch of third party applications such an SQL db. This is perfect for small projects or projects that don't need to persist a lot of data.

npm i enmap-json-sync
