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 🙏

Helpers for formatting numbers as Money, Percentages, and Fixed.

NPM

Install

npm install @insightlabs/number-formatter --save
#or
yarn add @insightlabs/number-formatter

Usage

Import Default Instance (Recommended)

Importing the default instance of Formatter will use the browser's current locale, if it can be determined. Otherwise, defaults to "en-US".

import format from "@insightlabs/number-formatter";

Import Class and create Instance

Importing the class definition will allow you to set the locale manually.

import { Formatter } from "@insightlabs/number-formatter";

const format = new Formatter("en-US");
//or
const format = new Formatter(); //equivalent to default import instance

Format as Percent

const result = format.asPct(0.1236, 1); 
// result == "12.4%"

Format as Money

const result = format.asMoney(12345.67, 2); 
//result == "$12,345.67"

Format as Fixed

const result = format.asFixed(123456.789, 1); 
//result == "123,456.8"

const year = format.asFixed(1984, 0, false); //no separator
//year = "1984";

Format as Phone Number

const result = format.asPhoneNumber(5128675309);
//result = "512-867-5309"
//or 
const result = format.asPhoneNumber(5128675309, "", ".");
//result = "512.867.5309"
//or
const result = format.asPhoneNumber(nonNumberOrString, "N/A");
//result = "N/A"

Format as Date

const d = new Date();
const date = format.asDate(d);
//date = "6/14/2019"
const time = format.asTime(d);
//time = "1:22:55 PM"
const datetime = format.asDateTime(d);
//datetime = "6/14/2019 1:22:37 PM"
