server-store

Local storage for nodejs which use filesystem to store data in JSON file.

Use case:

If there is a downstream third party service that always returns same set of data for a given type of request and which doesn't get updated frequently the we can cache the data at node layer instead of making a new service call. e.g: https://xyz.com/api/getZipCodes?state=CA => [95000, 95001, ....]

We can use local DB to address this but for the application which is stateless or no DB or used only for orchestration

This module writes/reads local file system in sync and async API is currently work in progress.

NOTE: Please don't use this as a database to store critical information, please fall back to service in case of Errors
