Aurora Elements

Aurora elements, hold info about HTMLElements class, attributes and tag name.

Install

npm i --save @ibyar/elements

yarn add @ibyar/elements

Example

import { hasNativeAttr } from '@ibyar/elements';

const div = document.createElement('div');
console.log(hasNativeAttr(div, 'for'));

import { htmlParser } from '@ibyar/elements';

const template = `<div #div name="data-div" (click)="onDivClick($event)">
                    <person-view [name]="alex" age="35" @edit="onPersonViewClick($event)" />
                  </div>`;
const htmlNode = htmlParser.toDomRootNode(template)(template)
console.log(htmlNode);

By default the parser has no registered info about structural/attributes directive.

You need to register them with inputs and outputs.

import { directiveRegistry } from '@ibyar/elements';


/**
 * register a structural directive, with name '*notifier' , the name must start with '*'.
 * with inputs `message` and `color`,
 * and output `action`.
 */ 
directiveRegistry.register('*notifier', {
    inputs: ['message', 'color'],
    outputs: ['action'],
});

/**
 *  register an attributes directive with name 'appConfirm'
 */
directiveRegistry.register('appConfirm', {
    inputs: [],
    outputs: [],
});

note:

the attributes directive has higher priority than regular element attributes, so if you registered an attributes directive with a name like 'style', 'class', 'id', 'name', etc... it will interpreted as an attributes directive and will be remove from the element attributes list.

import { directiveRegistry } from '@ibyar/elements';


/**
 * register an attributes directive with no input and no output.
 */
directiveRegistry.register('style');
