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

data-shifter

This package provides a data validation and transformation pipeline. Due to the functional nature of this package, it's easy to swap the components of the pipeline to dynamically generate different transformations.

Usage

The convert module leverages currying to build this pipeline:

const transformed = await convert(validator, fn=validate)(shifter)(data);

Where the arguments are:

  • validator: A schema validator (yup is used by the provided validators)
    • fn (optional): the name of the validator function to be called
    • Any promise-based validator with a fn that resolves with the validated data and rejects with an error can be used
  • shifter: A function that performs the transformation and returns the transformed data
  • data: An object to be validated and transformed

This package comes with a few predefined validators and shifters which can be obtained using the resolvers module (example), but the real power of this library comes from the fact that the pipeline just acts as a framework that custom validators and shifters can be plugged into (example).
