Aph

A very lightweight (3.66 kbs minified and 1.55 kbs gzipped), easy-to-use DOM manipulation library.

'a', 'p', 'h' are the first letters of Apheleia, the greek mythology spirit and personification of ease, simplicity and primitivity in the good sense.

Live samples

Sample:

<html>
  <body>
    <span></span>
    <span></span>
    <span></span>
  </body>
  <script>
    // Behooooold
    $$('span')
      .classList.add('test-class')
      .setAttribute('custom-attr-1', 'test-value-1')
      .setAttribute({ // Passing a key/value object works as well
          'custom-attr-2': 'test-value-2',
          'custom-attr-3': 'test-value-3'
      })
      .style.setProperty({
          color: 'red',
          background: 'pink',
          padding: 10
      })
      .textContent = 'Ooooops'
  </script>
</html>

Result:

...
  <span style="color: red; background: pink; padding: 10px;" class="test-class" custom-attr-1="test-value-1" custom-attr-2="test-value-2" custom-attr-3="test-value-3">
    Ooooops
  </span>
  <span style="color: red; background: pink; padding: 10px;" class="test-class" custom-attr-1="test-value-1" custom-attr-2="test-value-2" custom-attr-3="test-value-3">
    Ooooops
  </span>
  <span style="color: red; background: pink; padding: 10px;" class="test-class" custom-attr-1="test-value-1" custom-attr-2="test-value-2" custom-attr-3="test-value-3">
    Ooooops
  </span>
...

What for?

aph was developed with the following goals:

Being an easy way to create elements without writing repeating code;
Manipulate a collection of HTML Elements without writing lots of for()/.forEach()/...;
Be, barely, API-Less. Vanilla JS is awesome,

How does it work

aph creates a Proxy which allows you to access properties and methods of nodes inside a node collection as if you were dealing with the nodes itself.

Example:

1) $$('div')
Creates an Apheleia Collection around all divs and returns a proxy.

2) $$('div').classList
Returns a proxy of the classList of all divs
[DOMTokenList(0), DOMTokenList(1), DOMTokenList(1)]

3) aph identifies the type of the first entry (DOMTokenList) and creates
a proxy which passes all functions to the DOMTokenList.prototype.

4) $$('div').classList.add('test-class','test-class-2')

5) *PROFIT*

Any extended method with a name beginning with set/add/remove and not ending with a s, such as .setAttribute/.setProperty/.addEventListener/.removeEventListener, can be used by passing an object of key/value pairs.

$$('div').setAttribute('oneAttribute','atAtime')
$$('div').setAttribute({
  multiple: 'attributes',
  at: 'aTime'
})

$$(window).addEventListener({
  click() { ... },
  mousemove() { ... },
})

All Apheleia Collections and Proxies have these default methods:

// Iterates through all items on the colleciton
// Can 'return false' to break
$$('div').style.forEach()

// Returns a mapped Apheleia Collection or Proxy
$$('div').style.map(mapCallback)

// Returns a filtered Apheleia Collection or Proxy
$$('div').style.filter(filterCallback)

// Generic get method for getting a property
$$('div').style.get(propName)

// Generic set method for setting properties
$$('div').style.set(propName, propValue)
$$('div').style.set({
  propName: propValue,
  propName2: propValue2,
})

But... what about performance?

By using Proxies, the performance hit is not that big (comparing with the old way aph did its thing... oh boy. Seriously, don't try to polyfill Proxies).

You can run the benchmarks by opening the benchmark.html. The benchmark results vary a little bit between executions, sometimes a library runs faster than the others.

Have some benchmarks to show me? I'll be more than thankful!
Have some suggestions or critics? Talk to me!

Go see the documentation!

Why the code is not transpiled?

We're already using Proxies, which cannot be polyfilled, so we're already stuck with ES6. Might as well write the rest of the code with ES6 too ;)
