about

Domscript is a lightning fast dom query/manipulation tool that you can easily customize to suit your needs.

The goal of domscript is to enable developers to rapidly chain methods while achieving similar to vanilla js speed.

if you can query and manipulate the dom with javascript, you can already use domscript.

you should get the same results and errors as though you were writting vanilla js.

all prototype methods are optional
custom methods can be easily be built into the prototype chain
current maximum build size of 3.1kb minified
no regex/unsafe functions
about as close to using vanilla js speed as it gets.

installation

npm

stable release

$ npm install @angeal185/domscript --save

dev release

git

$ git clone https://github.com/angeal185/domscript.git

browser

<html>
  <head>
    <meta charset="utf-8">
    <script src="/path/to/domscript.mjs" type="module"></script>
    <!-- or -->
    <script src="/path/to/domscript.js"></script>
  </head>
</html>

index

build

$ npm run build will build domscript into the ./dist folder.

the config file is located at ./build/config.json.
the build source is located at ./lib/index.js.
config.includes allows you to enable/disable prototype methods from the final build.
You can also reorganize the order of the prototype chain based on your usage of the methods
reorganization should be done with your most used methods at the top.
you can also manually add custom methods to the prototype at ./lib/index.js.
the custom method names should be added and enabled to config.includes
config.export_as controls the variable name used to call domscript.
config.module_name controls the built output base name.
config.module_ext controls the built output file extension.
config.iuclude_utils controls adding the util function.
if none of your methods use domscripts util function config.iuclude_utils will exclude it from the build.
config.is_module controls the export method of domscript.
if you are not using domscript as a module, config.is_module should be false

performance

below is a very basic example of domscripts potential.

// jquery
console.time('jquery')
for (let i = 0; i < 1000; i++) {
  $('#test-id').addClass('test1').text('test1');
}
console.timeEnd('jquery');

// zepto
console.time('zepto')
for (let i = 0; i < 1000; i++) {
  $('#test-id').addClass('test2').text('test2');
}
console.timeEnd('zepto');

// umbrella.js
console.time('umbrella')
for (let i = 0; i < 1000; i++) {
  u('#test-id').addClass('test3').text('test3');
}
console.timeEnd('umbrella');

// vanilla javascript
console.time('javascript')
for (let i = 0; i < 1000; i++) {
  let item = document.getElementById('test-id');
  item.classList.add('test4');
  item.textContent = 'test4';
}
console.timeEnd('javascript');

// domscript
console.time('domscript')
for (let i = 0; i < 1000; i++) {
  d.id('test-id').addClass('test5').txt('test5');
}
console.timeEnd('domscript');


// jquery 157.0546875ms
// zepto 145.590087890625ms
// umbrella 143.53515625ms

// javascript 14.052001953125ms
// domscript 18.84423828125ms

your end results should always have domscript running similar speed to native js. the lower the amount of methods included in the domscript prototype, the faster and closer it should be. if you don't use it, exclude it.

index

set

d.set(cached_item).attr('readonly', true)
d.set(cached_item2).attr('readonly', true)

index

create

domscript was designed for query/manipulation. It has a basic create function but domscript's sister lib clonecript is a much better alternative and designed to work alongside domscript.

clonescript was made for creation and not query/manipulation clonescript

examples:

let item = d.create('div')
// get element by selector and add created div

d.id('test-id').append(item);

// do not add a proto within the proto
//d.id('test-id').append(d.create('div'));
