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 🙏

Button States

npm version DragsterJS gzip size

Helper functions to set button states for loading, loaded or disabled and auto-set loading states when its action is expected to take some time giving visual instant feedback to the user.

Installation

Setting up is pretty straight-forward. Just download the script from dist folder and include it in your HTML:

<script type="text/javascript" src="path/to/dist/button-states.min.js"></script>

NPM

Button States is also available on NPM:

$ npm install button-states

Initialization

Once the Button States script is loaded all functions will be available through the global variable window.ButtonStates, however to enable the auto-set loading state feature you need to call the function init:

Call the function ButtonStates.init( options ); passing the parameters:

  • options: Any of the script available options can be changed from the default settings by passing the new values here as an object.

Options Available

Currently Button States only accept one option:

var options = {
    autoLoadingButtonSelector: '[data-auto-loading-state]', // Any valid css selector to target buttons which use auto-set loading state
}
ButtonStates.init( options );

Basic Usage

Keep in mind Button States will only set the states of the button and your theme or page should provide the css code necessary to style the button for each of its state and add animations is necessary.

1. Auto set button to loading state when clicked

Usefull when you know the action of a button will likelly take a few seconds do process, to make it auto-set the loading state all you need to do is add an attribute to the button data-auto-loading-state, this will also disable to button click while on loading state:

<button type="submit" data-auto-loading-state>Submit</button>

To use this method you first need to initialize the script as explained above in the section "Initialization"above.

2. Set button state programatically

You can set any of these states to a button by passing it as a parameter to the function ButtonStates.setStates() and are available to use through the variable ButtonStates.states (see examples below):

  • NORMAL
  • DISABLED
  • LOADING
  • LOADED

In the example below we make every button on the page change it's state to loadingwhen clicked, this can be achieve individually be using the auto-set method as described above. This is a simple example to show how to use the function ButtonStates.setState( button, state ) where button is an html element and state is one of the states defined at ButtonStates.states.

// Set `loading` state to any button on the page when clicked
var button = document.querySelector( '.submit' );
button.addEventListener( 'click', function( e ) {
    ButtonStates.setState( e.target, ButtonStates.states.LOADING );
} )

Another useful way to use Button States would be to enable a button once a script finishes loading and is ready to process user input, like a mobile menu button:

( function() {
    // Enable a mobile menu button when the page finish loading
    var init = function() {
        var button document.querySelector( '.mobile-menu-button' );
        ButtonStates.setState( button, ButtonStates.states.NORMAL );
    }

    // Call init on page load
    window.addEventListener( 'load', init );
})();
