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 🙏

Thin wrapper around lru-cache with extended functionality.

Install

Install with npm:

$ npm install --save lru-cache-ext

Usage

Please refer to lru-cache.

Additional Options

cacheNull

Type: boolean Default: true

When set to other than true, the null value is not cached with memoize and memoizeSync.

Additional Functions

memoize(key: String, valueFn: function)

Only when the key is not present in cache (or has expired), valueFn is called and placed into cache.

The cached value is returned when it becomes available (important in the case where valueFn is async).

The cache is left empty if an error is thrown at any point in valueFn (even asynchronous).

Useful when multiple async operation need to access the same async information.

memoizeSync(key: String, valueFn: function)

Similar to "memoize", when key is not present (or has expired), valueFn is called and placed into the cache.

Cached value is returned from the function.

valueFn can be a synchronous or asynchronous function.

If valueFn is an asynchronous function and an error is thrown asynchronously, the cache is not invalidated.
