Ibyar elements, hold info about HTMLElements class, attributes and tag name.
Install
npm i --save @ibyar/elements
yarn add @ibyar/elements
Try the parser
- Ibyar Elements parser: https://ibyar.github.io/astexplorer/
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');
