Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

functional-memoize

Functional Memoize is a package to implement an approach of a generic memoization of functions from a functional programming point of view.

functional-memoize.cacheWrapper(findInCache, saveInCache, memoizeConfigOptions, functionToMemoize) ⇒ function

Curriable function to wrapp the function to be memoized with a provided cache strategy.

Kind: static method of functional-memoize
Returns: function - - Function that wrapp the functionToMemoize with the strategy of cache. This function is always async, return a Promise. The returned function has an atribute force, this force atribute is a function that force the use of the functionToMemoize and saveit in the cache.

| Param | Type | Description | | --- | --- | --- | | findInCache | function | Function to find in the cache implemented. | | saveInCache | function | Function to save in the cache implemented. | | memoizeConfigOptions | object | Object to configure the cahe options. | | memoizeConfigOptions.ttl | number | Time to live for the memoization by default is 1. | | memoizeConfigOptions.ttlMeasure | string | Measure of the time to live, ir use the same as moment (miliseconds, seconds, minutes, hours, days ...) by default is days. | | memoizeConfigOptions.functionName | string | The Implementation consider a unique cached. | | functionToMemoize | function | Function to be memoized by the cache wrapper. |

functional-memoize.inMemoryCacheWrapper(memoizeConfigOptions, functionToMemoize) ⇒ function

Curriable function to wrapp the function to be memoized with a in Memory cache strategy.

Kind: static method of functional-memoize
Returns: function - - Function that wrapp the functionToMemoize with the strategy of cache. This function is always async, return a Promise. The returned function has an atribute force, this force atribute is a function that force the use of the functionToMemoize and saveit in the cache.

| Param | Type | Description | | --- | --- | --- | | memoizeConfigOptions | object | Object to configure the cahe options. | | memoizeConfigOptions.ttl | number | Time to live for the memoization by default is 1. | | memoizeConfigOptions.ttlMeasure | string | Measure of the time to live, ir use the same as moment (miliseconds, seconds, minutes, hours, days ...) by default is days. | | memoizeConfigOptions.functionName | string | The Implementation consider a unique cached. | | functionToMemoize | function | Function to be memoized by the cache wrapper. |

functional-memoize.inMongoCacheWrapper(mongoDBConfig, memoizeConfigOptions, functionToMemoize) ⇒ function

Curriable function to wrapp the function to be memoized with a mongodb cache strategy.

Kind: static method of functional-memoize
Returns: function - - Function that wrapp the functionToMemoize with the strategy of cache. This function is always async, return a Promise. The returned function has an atribute force, this force atribute is a function that force the use of the functionToMemoize and saveit in the cache.

| Param | Type | Description | | --- | --- | --- | | mongoDBConfig | Object | MongoDB configuration options. | | mongoDBConfig.mongodbUri | String | mongoDB connection string. | | mongoDBConfig.mongodbCacheCollection | String | Name of the mongoDB collection. | | memoizeConfigOptions | Object | Object to configure the cahe options. | | memoizeConfigOptions.ttl | Number | Time to live for the memoization by default is 1. | | memoizeConfigOptions.ttlMeasure | String | Measure of the time to live, ir use the same as moment (miliseconds, seconds, minutes, hours, days ...) by default is days. | | memoizeConfigOptions.functionName | String | The Implementation consider a unique cached. | | functionToMemoize | function | Function to be memoized by the cache wrapper. |
