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 🙏

Readme

The gameface-rangeslider is part of the Gameface custom components suite. As most of the components in this suite it uses slots to allow dynamic content.

Installation

npm i coherent-gameface-rangeslider

Usage with UMD:

<script src="./node_modules/coherent-gameface-rangeslider/dist/rangeslider.production.min.js"></script>
  • add the gameface-rangeslider component to your html:
<gameface-rangeslider></gameface-rangeslider>

This is all! Load the file in Gameface to see the rangeslider.

Usage with JavaScript:

If you wish to import the RangeSlider using JavaScript you can remove the script tag and import it like this:

import { RangeSlider } from 'coherent-gameface-rangeslider';

or simply

import 'coherent-gameface-rangeslider';

Note that this approach requires a module bundler like Webpack or Rollup to resolve the modules from the node_modules folder.

How to use

To use simply add

<gameface-rangeslider></gameface-rangeslider>

to your html file.

Listening for slider update change

To listen for changes in the rangeslider you can attach an event listener to the sliderUpdate event

const volumeControl = document.querySelector('.example-volume-control');

volumeControl.addEventListener('sliderUpdate', ({ detail }) => { // detail is the value returned by the rangeslider
    // Logic here
})

Rangeslider attributes

You can use the following attributes to customize the rangeslider

|Attribute |Type |Default | Description |Notes | |---|---|---|---|---| |value | Number, Array (two handles) |0 | The initial value of the rangeslider | If the value attribute is not set it defaults to the min value if set set. | |min | Number | 0 | The minimum value of the rangeslider | Not working when the values attribute is set. | |max | Number | 100 | The maximum value of the rangeslider | Not working when the values attribute is set. | |step | Number | 1 | The step of the handle | Not working when the values attribute is set. | |grid | Boolean | false | Draws a grid with numbers or array entries | To enable it you just need to put 'grid' as attribute | |pols-number | Number | 5 | The number of pols the grid has | To use this you need to have 'grid' attribute set | |thumb | Boolean | false | Draws a thumb with a value for each handle | To enable it you just need to put 'thumb' as attribute | |two-handles | Boolean | false | Creates two handles to specify a range | To enable it you just need to put 'two-handles' as attribute. If enabled the value attribute is ignored. Not working when the values attribute is set. | |orientation | String | 'horizontal' | Either 'horizontal' or 'vertical' | Will change the orientation of the rangeslider to horizontal or vertical. | |custom-handle | String | '' | Element selector | Will find the element with the specified selector and will automatically render the slider value in it. This option will work when the two-handles option is set to false. | |custom-handle-left | String | '' | Element selector | Will find the element with the specified selector and will automatically render the left slider value in it. This option will work when the two-handles option is set to true. | |custom-handle-right | String | '' | Element selector | Will find the element with the specified selector and will automatically render the right slider value in it. This option will work when the two-handles option is set to true. | |values | Array | [] | Uses an array for the rangeslider | The array must be added in the following format '["value1", "value2"]' where the array is wrapped in single quotes and the values in double. If there is an Array the two-handles, min and max attributes are ignored |

Examples

<gameface-rangeslider orientation="horizontal" min="56" max="255" grid thumb step="20"><gameface-rangeslider>

<gameface-rangeslider orientation="horizontal" min="56" max="255" grid thumb two-handles step="20"></gameface-rangeslider>

<gameface-rangeslider orientation="horizontal" grid thumb value="Hard" values='["Easy","Normal", "Hard", "Expert", "Nightmare"]' step="20"></gameface-rangeslider>

<gameface-rangeslider orientation="vertical" min="56" max="255" grid thumb step="20"><gameface-rangeslider>

Dynamic attributes (v.3.1.0)

In version 3.1.0 are added the dynamic attributes of the rangeslider component. Each attribute from the table can now be changed via JavaScript or by changing the attribute value of the gameface-rangeslider element. You can also add new attributes to the rangeslider runtime. The component is watching for changes so runtime it can be configured to behave differently.

value

You can set the value of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.value = ${newValue};
// or
rangeslider.setAttribute('value', ${newValue});

The newValue can be either a number or string when values attribute is set.

You can get the value of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.value);
// or
console.log(rangeslider.getAttribute('value'));

Behaviors

If the newValue is invalid then the rangeslider is going to set the value to minimum.

  • When the rangeslider works with number values (the values attribute is not set).

    • If the newValue is more that the maximum allowed then it will be set to maximum.
    • If the step attribute is used then setting the value is going to be pre-calculated to the next/previous value based on the step value. For example if the rangeslider has values from 0 to 100 and the step attribute value is 20 then setting value to 15 will be pre-calculated and set to 20. And if the value is 5 then will be set to 0.
  • When the rangeslider works with values array (the values attribute is set).

    • You need to specify the newValue to be one from the values array. Otherwise it will be invalid and be set to the first value of the values array.

For rangeslider that has two-handles enabled, setting the value is not possible for now.

min/max

The min and max attributes are working just when the values attribute is not used.

You can set them to the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.min = ${newValue}; // same for the `max`
// or
rangeslider.setAttribute('min', ${newValue}); // same for the `max`

The newValue should always be a number.

You can get the min or max of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.min);
// or
console.log(rangeslider.getAttribute('min'));

Behaviors

min and max are not taking effect when values attribute is set!

Also when you change the min or max and the current value is less/greater than min/max it will be automatically be set to min/max value. This behavior works as well when the slider has two handles enabled by the two-handles attribute.

When the min or max are changed and if the grid of the rangeslider is enabled then it will be precalculated and re-rendered showing the new and true values of the slider.

step

The step attribute is not taking effect when the values attribute is used.

You can set step to the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.step = ${newValue};
// or
rangeslider.setAttribute('step', ${newValue});

The newValue should always be a number.

You can get the step of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.step);
// or
console.log(rangeslider.getAttribute('step'));

Behaviors

When the step is changed then the rangeslider will pre-calculate the current value to match the step conditions! This behavior works as well when the slider has two handles enabled by the two-handles attribute.

grid

You can enable/disable the grid of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.grid = ${newValue};
// or
rangeslider.setAttribute('grid', ${newValue});

The newValue should always be a boolean(true or false).

You can get the grid of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.grid);
// or
console.log(rangeslider.getAttribute('grid'));

polsNumber

You can set the pols number in the grid of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.polsNumber = ${newValue};
// or
rangeslider.setAttribute('pols-number', ${newValue});

The newValue should always be a number above 1

You can get the grid of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.polsNumber);
// or
console.log(rangeslider.getAttribute('pols-number'));

thumb

You can enable/disable the thumb of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.thumb = ${newValue};
// or
rangeslider.setAttribute('thumb', ${newValue});

The newValue should always be a boolean(true or false).

You can get the thumb of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.grid);
// or
console.log(rangeslider.getAttribute('thumb'));

two-handles

The two-handles attribute is not taking effect when values attribute is used.

You can enable/disable the two-handles of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.twoHandles = ${newValue};
// or
rangeslider.setAttribute('two-handles', ${newValue});

The newValue should always be a boolean(true or false).

You can get the two-handles of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.twoHandles);
// or
console.log(rangeslider.getAttribute('two-handles'));

Behaviors

As the value is not taking effect when the two-handles is enabled then enabling it it will reset the current value to the min and max of the rangeslider. And if you disable the two-handles and there is a value it will be correctly set.

custom-handle, custom-handle-left, custom-handle-right

The custom-handle attribute is not taking effect when two-handles attribute is used. The custom-handle-left and custom-handle-right attributes are not taking effect when two-handles attribute is not used.

You can retarget the custom handle of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.customHandle = ${newValue}; // works the same for the customHandleLeft and customHandleRight
// or
rangeslider.setAttribute('custom-handle', ${newValue}); // works the same for the custom-handle-left and custom-handle-right

The newValue should always be a string that represents a CSS selector (such as #my-target, .my-target-class, etc.).

You can get the custom handle/s DOM elements of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.customHandle); // works the same for the customHandleLeft and customHandleRight
// or
console.log(rangeslider.getAttribute('custom-handle')); // works the same for the custom-handle-left and custom-handle-right

Note that it will return the DOM element of the custom handle and not the selector!

Behaviors

For now when the custom-handle/-left/-right are changed then the new target is not going to receive the value of the slider until it has not changed!

values

You can add values of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.values = ${newValue};
// or
rangeslider.setAttribute('values', ${newValue}); // For example rangeslider.setAttribute('values', '["Easy", "Hard", "Expert"]')

The newValue should always be an array with string values.

You can get the values of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.values);
// or
console.log(rangeslider.getAttribute('values'));

Behaviors

If values are set then the rangeslider is going to be re-rendered based on the added values.

orientation

You can add orientation of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
rangeslider.orientation = ${newValue};
// or
rangeslider.setAttribute('orientation', ${newValue});

The newValue should always be either 'horizontal' or 'vertical'. Any other value will fallback to 'horizontal'.

You can get the orientation of the rangeslider by doing

const rangeslider = document.queryselector('gameface-rangeslider');
// either
console.log(rangeslider.orientation);
// or
console.log(rangeslider.getAttribute('orientation'));
