@xaro/micro-dom

The DOM control micro-library has several functions for manipulating the classes, styles, and attributes of elements. (See all methods below)

Also has all the array functions and actually inherits from it

Install

$ npm install @xaro/micro-dom

Usage

import _, { I_MicroDOM } from '@xaro/micro-dom';

const els: I_MicroDOM = _('.test-1', document.querySelector('.test-2'), ...document.querySelectorAll('.test-3') /* ... */);

els.addClass('class-A', 'class-B' /* ... */)
  .removeClass('class-A', 'class-B' /* ... */)
  .toggleClass('class-A')
  .css({
    color: 'red',
    'font-size': '15px',
    backgroundColor: 'blue'
    /* ... */
  })
  .attr({
    'data-test-1': 'test-1',
    'data-test-2': 'test-2',
    /* ... */
  })
  .append('content');

Other methods description see below in the section Interface

Additional features

The nextTick method for sequential execution of functions through setTimeout with a delay of 0, like Vue's $nextTick, but for an array of functions. Useful for adding or removing classes when you need to wait for the browser to render, like in the example below:

import _ from '@xaro/micro-dom';

const els = _('.test');

const cbs = [
  () => els.addClass('class-A'),
  () => els.addClass('class-B')
];

els.nextTick(...cbs);

// Result:
// In setTimeout, the first passed callback function is started, and a new setTimeout for the next function, and so on until all functions are executed

Also, you can only import the nextTick function, which returns void, but also not tied to the MicroDOM instance.

import { nextTick } from '@xaro/micro-dom';

nextTick(() => console.log('I\'m call in setTimeout(cb, 0);'));
