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 🙏

1. Fuzzy search in an array of strings

const SearchEngine = require('fuzzy-search-and-comparison').SearchEngine;
let searchEngine = new SearchEngine();

// Define the names array
let names = [
  "Tiffany Ellis", "Jon Mcdaniel", "Marcella Bailey",
  "Earnest Hicks", "Christian Mclaughlin", "Martin Baker",
  "Jodi Hogan", "Willie Estrada", "Joe King",
  "Irene Hall", "Leo Wilkerson", "Dominick Weber",
  "Elena Perry", "Kristy Gibson", "James Cunningham",
  "Tina Ross", "Beulah Mccarthy", "Carlos Wallace",
  "Doris Barker", "Josephine Gibbs", "Erik Wells",
  "Elsie Erickson", "Jerald Adkins", "Alfred Huff",
  "Blanche Holt", "Elvira Wright", "Kenneth Fitzgerald",
  "Joan Robinson", "Melissa Tucker", "Evelyn Clark",
  "Gerald Perkins", "Johnny Burton", "Hector Herrera",
  "Gayle Williams", "Bernice Harrington", "Timmy Brady",
  "Jennie Moss", "May Greer", "Thelma Lloyd",
  "Ida Craig", "June Hughes", "Beverly Graves",
  "Alfonso Ramos", "Cecilia Colon", "Ed Barnes",
  "Ken Zimmerman", "Nora Hunter", "Seth Harris",
  "Kristina Rivera", "Archie Brown"
];

// Set count of required results (3 by default)
searchEngine.setStackMaxLength(5);

// Searching of names similar to "Jonh Baker" in the names array
console.log(
  searchEngine.search("John Baker", names)
);

/*
[ { sample_string: 'John Baker',
    tested_string: 'Martin Baker',
    pattern: '*n Baker',
    symbols: 7,
    gaps: 1 },
  { sample_string: 'John Baker',
    tested_string: 'Doris Barker',
    pattern: '*o* Ba*ker',
    symbols: 7,
    gaps: 3 },
  { sample_string: 'John Baker',
    tested_string: 'Johnny Burton',
    pattern: 'John* B*r*',
    symbols: 7,
    gaps: 3 },
  { sample_string: 'John Baker',
    tested_string: 'Jon Mcdaniel',
    pattern: 'Jo*n *a*e*',
    symbols: 6,
    gaps: 4 },
  { sample_string: 'John Baker',
    tested_string: 'Joan Robinson',
    pattern: 'Jo*a*n *',
    symbols: 5,
    gaps: 3 } ]
*/

2. Fuzzy search in an array of objects with nested strings

let nestedNames = [
  {name: "Tiffany Ellis"},
  {name: "Jon Mcdaniel"},
  {name: "Marcella Bailey"},
  {name: "Earnest Hicks"},
  {name: "Christian Mclaughlin"},
  {name: "Martin Baker"},
  {name: "Jodi Hogan"},
  {name: "Willie Estrada"},
  {name: "Joe King"},
  {name: "Irene Hall"}
];

// Set count of required results (3 by default)
searchEngine.setStackMaxLength(1);

// Searching of names similar to "Jonh Baker" in the names array (callback
// extracts name from an object)
console.log(
  searchEngine.search("Martin Bailey", nestedNames, (item) => {
    return item.name;
  })
);

/*
[ { sample_string: 'Martin Bailey',
    tested_string: 'Marcella Bailey',
    pattern: 'Mar* Bailey',
    symbols: 10,
    gaps: 1 } ]
*/

3. Fuzzy comparing of strings

const StringsComparator = require('fuzzy-search-and-comparison').StringsComparator;
let stringsComparator = new StringsComparator();

// full view
console.log(
  stringsComparator.compare('contact', 'contract')
);

console.log(
  stringsComparator.compare('modification', 'modernization')
);

// simplified view
console.log(
  stringsComparator.compare('contact', 'contract', true)
);

console.log(
  stringsComparator.compare('modification', 'modernization', true)
);

/*
cont[|r]act
mod[|ern]i[fic|z]ation
cont*act
mod*i*ation
*/
