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

This is just a simple custom react hook for using filters on some data. First You have to make sure your data is array and each element in it is an object that contain "tags" which is an array of strings. I know it's a little confusing and has a lot of rules but i will try to make it as simple as possible in future. You can see the example below:

const initialData = [
    {... ,
        tags : [...]
    }, 
    {..., 
        tags: [...]
    }
]

Second you have to pass filters which are arrays of strings. e.g:

const filters = ['tag1', 'tag2', 'tag3']

and there you go you are finished.

Now let's see what data you will get: First of all you will get all the filters as an object which either are true or false.

{
    tag1: true,
    tag2: true,
    tag3: true
}

Then you will get a function that you can use to filter the data. e.g on a button.

And finally you will get the filtered Data which is an array of objects and you can just map over it. Here is the final code:

const [filtersToDisplay, changeFilter, filteredData] = useFilter(initData, filters)

I will be completing this in the future and will add more features and of course with better documentation.
