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

value-extractor

This is a simple and easy-to-use JavaScript library that allows you to extract values from a string based on a pattern. It is useful when you have a string with a predictable structure and you want to extract specific values from it.

Use in Browser

Use directly in the browser with jsDelivr or unpkg.

<!DOCTYPE html>
<html>
    <body>
        <script src="https://cdn.jsdelivr.net/npm/value-extractor@latest"></script>
        <script>
        const str = "change 100 kg to pounds";
        const pattern = "change {quantity} {from_unit} to {to_unit}";
    
        const values = valueExtractor(str, pattern);
        console.log(values)
        // OUTPUT :
        // {
        //     quantity: "100",
        //     from_unit: "kg",
        //     to_unit: "pounds"
        // }
        </script>
    </body>
</html>

Install as a NPM package

To install value-extractor package, run the following command:

npm i value-extractor

Usage

To use the String Value Extractor, import the extractValues function and call it with a string and a pattern:

import valueExtractor from 'value-extractor';

const values = valueExtractor('/2012/08/12/test.html', '/{year}/{month}/{day}/{title}.html');

console.log(values);
// Output: { "year": "2012", "month": "08", "day": "12", "title": "test" }

The extractValues function returns an object with keys based on the pattern, and values based on the extracted values.
