node package manager


A simple module to synchronously write files to a directory and read them back. It's purpose is to act as a minimalist filesystem cache. The scope of this is limited to NodeJS (not the browser) and the file system (not runtime memory).


npm install --save micro-cache


Have a directory that you want to read and write to

mkdir cache

Now implement this module in your script. See test/index.js for full implementation. This uses winston for logging, you can run this as LOG_LEVEL=debug node index.js for get full output.

import MicroCache from 'micro-cache';
cache = new MicroCache('./cache');
// Write and overwrite existing
cache.write('validFileName', 'Any String Will Do');
// Write only if it doesn't exist
cache.write('anotherFileName', 'More data here', true);
// Read a file
let data ='anotherFileName');
// Delete a file


Pull requests are welcomed, but, if you want to add features simply just use one of the other many existing node modules that do caching.
