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 🙏

React Masked Field Build Status

A masked field component built in React.

The MaskedField component is a text input field that allows you to restrict and format the values that can be entered into it, while informing the user of the expected input. Common uses include dates, phone numbers, social security numbers and tax IDs.

Example

import MaskedField from 'react-masked-field';

ReactDOM.render(
  <MaskedField mask="99/99/9999" onComplete={() => console.log('Date is ' + date)} />,
  document.getElementById('demo'),
);

Installation

Install from npm:

npm install react-masked-field

Props

mask?: string

The mask applied to the value of the field. For each character of the mask that matches a translation, the input character will be restricted to the corresponding regular expression. If no mask is provided, it will function like a normal input element.

translations?: { [char: string]: RegExp }

default:

{
  '9': /\d/,
  'a': /[A-Za-z]/,
  '*': /[A-Za-z0-9]/
}

Additional (or overridden) translations for converting mask characters to regular expressions.

onComplete?: (val: string) => void

The onComplete event is triggered when the mask has been completely filled. The value of the field is passed to the event handler.

inputRef?: (node: HTMLInputElement | null) => any

A ref passed to the internal input element.

placeholder?: string

default: the value of the mask prop

This functions just like a normal input placeholder prop. If no placeholder is provided, the mask prop will be used as the placeholder.

Other props

In addition to the props above, MaskedField should handle all supported input props.
