makel-dom
easily create and retrieve DOM elements with CSS like syntax
Installation
npm i makel-domDescription
This project was forked from hekigan.
Makel and Dom are good partners. Makel creates dom elements while Dom retrieves them. Together they make dynamically loading HTML simple and elegant.
Suppose we want to dynamically add a new blog post.
<!-- page html-->
<body>
<div id="blog-container">
<article class="blog-post">
<p>Paragraph 1</p>
<img class="thumbnail" src="photo1.png">
</article>
<!-- we want to add another post here
<article class="blog-post">
<p>Paragraph 2</p>
<img class="thumbnail" src="photo2.png">
</article>
-->
</div>
</body>Doing this using plain javascript can be a hassle.
// typical way of dynamically add a blog post with javascript
let blog = document.createElement('article')
blog.classList.add('blog-post')
let p = document.createElement('p')
p.innerText = 'Paragraph 2'
let img = document.createElement('img')
img.classList.add('thumbnail')
img.src = 'photo2.png'
blog.appendChild(p).appendChild(img)
document.getElementById('blog-container').appendChild(blog)With the help of Makel and Dom, things become easier.
// using makel-dom
const {makel, dom} = require('makel-dom')
let blog = makel('article.blog-post',
makel('p', 'Paragraph 2'),
makel('img.thumbnail[src=photo1.png]'))
dom('#blog-container').appendChild(blog)Usage
Basic
The simplest example is adding an empty div tag to the document's body.
CommonJS
const {makel, dom} = require('makel-dom')
const body = dom('body')
body.appendChild(makel()) // makel without parameters creates a <div>ES6
import {makel, dom} from "./node_modules/makel-dom/src/index.js"
const body = dom('body')
body.appendChild(makel()) // makel without parameters creates a <div>Makel usages
Makel helps create DOM elements.
const {makel, dom} = require('makel-dom')
let elt = null
// some examples
elt = makel() // <div></div>
// create a span node with an id
elt = makel('span#my-id') // <span id="my-id"></span>
// add class
elt = makel('span.my-class') // <span class="my-class"></span>
// add id and class
elt = makel('span#my-id.my-class') // <span id="my-id" class="my-class"></span>
// add class and attributes
elt = makel('a[href=#].link') // <a class="link" href="#"></a>
// add content to the new element (text & other nodes)
elt = makel('div',
'paragraphs',
makel('p', 'paragraph 1'),
makel('p', 'paragraph 2')
)
// <div>
// paragraphs
// <p>paragraph 1</p>
// <p>paragraph 2</p>
// </div>
// add the generated element to the DOM
dom('body').appendChild(elt)Dom usages
Dom is equivalent to document.querySelector().
const {dom} = require('makel-dom')
// return the element in DOM with given id
// same as document.querySelector('#myid')
dom('#myid')
// return the first <div> in DOM that contains a child <p>
// same as document.querySelector('div>p')
dom('div>p')
// return the first element with class blog-post
// same as document.querySelector('.blog-post')
dom('.blog-post')In addition, Dom can select elements relative to another element, even ones not yet added to the DOM.
const {makel, dom} = require('makel-dom')
let elt = makel('', // short for 'div'
makel('#1'), // short for 'div#1'
makel('#2.selected'),
makel('#3.selected')
)
// <div>
// <div id="1"></div>
// <div id="2" class="selected"></div>
// <div id="3" class="selected"></div>
// </div>
// highlight the first <div> in elt with class 'selected'
dom(elt, 'div.selected').style.backgroundColor = '#FFFF00'
// finally add to DOM
dom('body').appendChild(elt)Doms usages
Overlooked by most, Dom has a brother Doms who likes to keep to himself. Yet when called upon, Doms is kind and offers plenty of help. Doms can find all the elements Dom misses.
<!--page html-->
<ol>
<li>item1</li>
<li>item2</li>
<li>item3</li>
</ol>const {dom, doms} = require('makel-dom')
dom('ol>li') // <li>item1</li>
// same as document.querySelectorAll('ol>li')
doms('ol>li')
// NodeList(3) [
// <li>item1</li>,
// <li>item2</li>,
// <li>item3</li>
// ]Module Imports
To require() a module, your code will have to be running on a server that supports CommonJS. Alternatively, bundlers such as Browserify and Webpack can bundle the code for use with non-CommonJS servers.
// ---------- app.js ----------
const {makel, dom, doms} require('makel-dom');
dom("body").appendChild(
makel("p", "Hello World")
);Then run the bundle command.
browserify app.js > bundle.js<!-- index.html -->
<!DOCTYPE html>
<html>
<script src="bundle.js"></script>
</html>If you are using ES6, then CommonJS is not needed. Simply add an import statement and run the module from a server.
<!-- index.html -->
<!DOCTYPE html>
<html>
<script type="module" src="app.js"></script>
</html>// ---------- app.js ----------
import {makel, dom, doms} from "./node_modules/makel-dom/src/index.js"
dom("body").appendChild(
makel("p", "Hello World")
);You can also reference the code directly through a <script> tag. Download the source here.
<!-- index.html -->
<!DOCTYPE html>
<html>
<script src="./makel-dom.js"></script>
<script>
dom("body").appendChild(
makel("p", "Hello World")
);
</script>
</html>Builds
The ES6 version is located in the src folder. The CommonJS version gets placed in lib and is auto compiled by Babel.
npm run build # compile with babelThe non-module version for use with <script> tags is in the dist folder and compiles from src.
npm run vanilla # generate plain jsTests
npm run testnpm run lint:testLicense
The code is available under the MPL-2.0 license.
