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.

Reselect Utils

Install

Install from the NPM repository using yarn or npm:

yarn add reselect-utils

npm install reselect-utils

Motivation

Such projects as Reselect and Re-reselect try to solve the task of memoization. But there is no standard solutions for some applied problems. This library was created to try to systematically solve the following problems:

Work with optional objects as a source for selection.
Binding parametric selectors to specific property values.
Adaptation of parametric selectors to the new parameter interface (useful for creating parametric structured selectors).
Using selection results as parameters for a new selection.
Calculating the aggregate value from a collection of selector results.
Structuring of selection results (more proper typed version of structured selector and cached structured selector).
Implementation of key selectors composition (useful for key selector creator usages).

Credits

Reselect Utils is inspired by projects such as Reselect, Re-reselect and ts-optchain. Also functional programming principles are used for design of this library. For example, Chain Selector was inspired by Monad Pattern.
