In-memory cache module

Save stuff in-memory!

Summary

Simple cache for saving object in-memory. Each value gets a timestamp, which marks how long the value is fresh. Freshness defaults to one hour.

Options

Pass in a freshnessDuration to set how long a value is fresh in the cache. The cache uses moment to handle the timestamps. The parameter is an object literal created using the add() method, as shown in MomentJS docs

const cache = require('frivillig-cache')({ year: 1, seconds: 12 });

Tests

Use npm test to run the tests. Remember to install the dependencies first using npm install.

Example usage

Below is a short example of how you can use this cache.

const cache = require('frivillig-cache')();

cache.set('key', { foo: bar });

if (cache.hasFresh('key')) {
    console.log(`Reading a fresh value from cache: ${cache.get('key')}`);
} else if (cache.has('key')) {
    console.log(`Reading a stale value from cache: ${cache.get('key')}`);    
}
