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 🙏

IU Health Validation

The Node module that controls the form validation used on Riley, IU Health Surveys, and more. Powered by jquery.inputmask, Parsley.js and jQuery.

Installation/Quick Start

$ npm i -S trendyminds/iu-health-validation
import IUHValidation from 'iu-health-validation';
new IUHValidation( $('[data-whatever-your-form-element-is]') );

Overview

You can validate forms on the site by adding some data- attributes to various form fields.

Example form code without validation

Take the following form code as an example. Note: This isn't necessarily the standard format of all forms on the site. Some code has been modified simply to be more readable.

<form>
  <label>
    First Name: <span class="form__required">*</span>
  </label>
  <input type="text" name="first_name">

  <label>
    Last Name: <span class="form__required">*</span>
  </label>
  <input type="text" name="last_name">

  <label>
    Email: <span class="form__required">*</span>
  </label>
  <input type="email" name="email">

  <label>
    Favorite color: <span class="form__required">*</span>
  </label>
  <select name="favorite_color">
    <option value="">Select a color</option>
    <option value="Blue">Blue</option>
    <option value="Green">Green</option>
    <option value="Red">Red</option>
    <option value="Yellow">Yellow</option>
  </select>

  <label>
    Favorite pizza topping: <span class="form__required">*</span>
  </label>
  <fieldset>
    <label><input type="radio" name="favorite_pizza_topping" value="Sausage"> Sausage</label>
    <label><input type="radio" name="favorite_pizza_topping" value="Pepperoni"> Pepperoni</label>
    <label><input type="radio" name="favorite_pizza_topping" value="Cheese"> Cheese</label>

How to enable form validation

The custom form validation we use on the site will begin working on this form after doing the following:

  1. Adding data-validate to the <form> tag.
  2. Adding either HTML5/ParsleyJS validation rules to each input or using a valid selector found in the FormValidation.coffee file.

Custom validation rules

Type | Data Attribute | Error Message | Requirements | ----------------|------------------------------------|----------------------------------------------------|------------------------------------------------| First Name | data-validate-first-name | "Please enter your first name" | Required, must be 2 characters minimum | Last Name | data-validate-last-name | "Please enter your last name" | Required, must be 2 characters minimum | Email | data-validate-email | "Please enter a valid email" | Required, must be a valid email address | Zip Code | data-validate-zip-code | "Please enter a zip code" | Required, must be 5 characters, must be digits | Phone | data-validate-phone | "Please enter a valid phone number" | Required, must be in a (XXX) XXX-XXXX format | Birthdate | data-validate-birthdate | "Please enter a valid date of birth" | Required, must be in a XX/XX/XXXX format | Comment | data-validate-comment | Standard "is required" message | Required, must be between 5-2500 characters | Field Limit | data-parsley-field-limit="1000" | "This field cannot be more than X characters long" | Required, cannot be more than 1000 characters |

Example form with validation applied

<!--
  The form must have a data-validate data attribute to enable validation
-->
<form data-validate>
  <label>
    First Name: <span class="form__required">*</span>
  </label>
  <input type="text" name="first_name" data-validate-first-name>

  <label>
    Last Name: <span class="form__required">*</span>
  </label>
  <input type="text" name="last_name" data-validate-last-name>

  <label>
    Email: <span class="form__required">*</span>
  </label>
  <input type="email" name="email" data-validate-email>

  <label>
    Favorite color: <span class="form__required">*</span>
  </label>
  <select name="favorite_color" required>
    <option value="">Select a color</option>
    <option value="Blue">Blue</option>
    <option value="Green">Green</option>
    <option value="Red">Red</option>
    <option value="Yellow">Yellow</option>
  </select>

  <label>
    Favorite pizza topping: <span class="form__required">*</span>
  </label>
  <!--
    To validate a field group you must wrap the group with a fieldset and then
    add the element below as the place where your error message will display.
    Note: Only one field is required to have the "required" attribute because they
    all share the same name.
  -->
  <fieldset>
    <label><input type="radio" name="favorite_pizza_topping" value="Sausage" required> Sausage</label>
    <label><input type="radio" name="favorite_pizza_topping" value="Pepperoni"> Pepperoni</label>
    <label><input type="radio" name="favorite_pizza_topping" value="Cheese"> Cheese</label>
    <div data-validate-errors></div>
  </fieldset>
