Memoizator

A promise-friendly memoize package

Uses the memoization technique to optimize expensive function results storing their results. You can use this technique over a wide range of applications.

const factorial = require('../lib/factorial')
const memoizator = require("memoizator")

const factorialMemoized = memoizator(factorial, { ttl: 600000 })


export default async function calcFactorial(req, res) {
    try {
        const { factor } = req.query
        
        const data = await factorialMemoized(factor)

        res.json({ data })
    } catch (e) {
        res.status(500).json({ error: 'Internal Server Error', details: e.message })
    }
}

This package allows you to use the memoization over promises functions and allow a fine-granded control over the cache configuration to avoid memory issues and others.
