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

Quick selector

Syntactic sugar for querySelector, querySelectorAll, & addEventListener allowing you to select, modify, and add event listeners for multiple elements in one line of code. Tiny package (<1KB GZIP). All Javascript events are supported.

Install

Node

npm install quick-selector
import qs from 'quick-selector'
// or
const qs = require('quick-selector')

Browser

<script src="https://unpkg.com/quick-selector/dist/qs.js"></script>

Usage

Selecting

Selecting <div class="box"> elements, use any CSS selectors:

const boxes = qs`div.box`

This always returns an array of elements, not just one element.

Events

Adding and removing click event listener:

const clickEvent = () => console.log('Clicked!')
qs`#custom-button`.click(clickEvent)

Removing event listener:

qs`#custom-button`.remove.click(clickEvent)

Filtering

Selecting only .element elements with the innerHTML value of 'Apples':

const filtered = qs`.subtitle`.filter(element => element.innerHTML === 'Apples')

Selecting only the first .subtitle element and adding a class (only(0) returns the first selected element, only(1) returns the second, etc.):

qs`.subtitle`.only(0).set(element => element.classList.add = 'first-subtitle')

Setting & getting

Setting text colour of elements to red:

qs`p`.set(el => el.style.color = 'red')

Getting an array containing the text content of each <p> element:

const paragraphText = qs`p`.get(el => el.textContent)

Modifying vanilla-selected elements

Adding a blur event to a list of elements selected with querySelectorAll:

const elementList = document.querySelectorAll('input')
qs(elementList).blur(event => console.log(`${event.target} lost focus`))

Comparison

Selecting and adding two event listeners

// Quick selector
qs`input.email`.input(ev => console.log(ev.target.value)).click(ev => ev.target.value = '')

// Vanilla JS
const emailInput = document.querySelectorAll('input.email')
for (const input of emailInput) {
  input.addEventListener('input', ev => {
    console.log(ev.target.value)
  })
  input.addEventListener('click', ev => {
    ev.target.value = ''
  })
}

Selecting, filtering selection, adding event listener, setting text colour

const clickFunc = () => console.log("I've been clicked")

// Quick selector
qs`p.text`.filter(el => el.innerHTML.startsWith('Hello')).click(clickFunc).set(el => el.style.color = 'red')

// Vanilla
const textBox = document.querySelectorAll('p.text')
for (const box of textBox) {
  if (box.innerHTML.startsWith('Hello')) {
    box.addEventListener('click', clickFunc)
    box.style.color = 'red'
  }
}

Adding a change event to every other textarea, from the second

// Quick selector
qs`textarea`.filter((el, index) => index % 2).change(ev => ev.target.value = 'Changed')

// Vanilla
const textareas = querySelectorAll('textarea')
for (i = 0; i < textareas.length; i++) {
  if (i % 2) {
    textareas[i].addEventListener('change', ev => {
      ev.target.value = 'Changed'
    })
  }
}

// Vanilla functional
const textareas = Array.from(querySelectorAll('textarea'))
textareas.filter((el, index) => index % 2).forEach(el => {
  el.addEventListener('change', ev => {
    ev.target.value = 'Changed'
  })
})

API

Query function

| Function | Arguments | Returns | | ---------- | ------------------------------------------------------------ | ------------------------------------------------------------ | | qs``, qs() | String or Array. Input a CSS selector text string, or an array of HTML elements | An array of HTML elements, with a special set of methods attached |

Query function methods

| Method | Arguments | Returns | Notes | | -------------- | ------------------------------------------------------------ | ----------------------------------------------------------- | ------------------------------------------------------------ | | .eventName() | Function. A function to be added to the event. | The templated array it was called upon. | Every single event compatible with the user's browser will work. See Examples: .click, .mousedown, .blur. | | .remove | None. Use in conjunction with an eventName() method. | N/A | Use .remove before an eventName() function, with the original function as the argument. Example: .remove.click(clickFunction). | | .set() | Function. Pass a function that will be applied to a Array.forEach() method, iterating through the object. | The templated array it was called upon. | More info on Array.forEach() - MDN. | | .get() | Function. Pass a function that will be applied to a Array.map() method, iterating through the object. | A new array containing the return values from the function. | More info on Array.map() - MDN. | | .filter() | Function. Pass a function that will be applied to a Array.filter() method, iterating through the object. | A templated array containing only the filtered elements. | More info on Array.filter() - MDN. | | .only() | Number. Pass a positive integer, corresponding to the index of the item in the quick-select array. | A templated array containing only the selected element. | .only(0) selects the first item on the page that matched the quick-select query, only(1) selects the second, etc. |

Note: All Array methods work, but the above methods all return a templated quick-select array (apart from .get()), and can be used with method chaining.
