Ibyar Aurora, is a web framework, that can create and define a Web Component standards ('custom elements', 'Shadow DOM' and 'HTML Templates'), that compatible with other frameworks, using Typescript.

This framework build with-in a embedded JavaScript Engine @ibyar/expressions to execute Template syntax and attributes binding.

how to bundle your package before publish

# always run ibyar cli to pre-build (AOT) your template and view types.
ibyar --build
#or
ibyar --build --watch

How to use:

`HTML -- template parser example`

in a polyfills.ts file

use aurora zone for detect changes

import 'zone.js';
import { bootstrapZone } from '@ibyar/aurora';
bootstrapZone('aurora');

or use manual Zone, if you don't like to use Zone.js all the events like rxjs observables, setTimeout and fetch, etc.. can't be detected.

import { bootstrapZone } from '@ibyar/aurora';
bootstrapZone('manual');

or use proxy Zone, if you don't like to use Zone.js but still like to have full change detection for your application. it my be hard in debugging your application.

import { bootstrapZone } from '@ibyar/aurora';
bootstrapZone('proxy');

you still can control the zone peer component while define your component by add zone t one of the zone types 'aurora', 'manual' and 'proxy'. if aurora is selected, you need to import the Zone.js package.
the zone property in the @Component({zone: 'manual'}) is optional and will get the default value from bootstrapZone()


import { Component, HostListener, isModel, OnDestroy, OnInit } from '@ibyar/aurora';
import { interval, Subscription } from 'rxjs';

@Component({
	selector: 'pipe-app',
	zone: 'AURORA',
	template: `
	<style>.bs-color{color: var({{currentColor}});}</style>
	@for(let color of colors; let i = index, isOdd = odd) {
		isOdd :{{ isOdd? 'odd': 'even'}}
		color: {{color}}
	}
	<!-- Local template variables -->
		
	@let name = user.name;
	@let name = user.name, age = user.age; <!-- comma separated variable declaration -->
	@let greeting = 'Hello, ' + name;
	@let data = data$ | async;
	@let pi = 3.1459;

Integration with `Webpack`

add @ibyar/cli as loader

module.exports = {
  entry: './src/index.ts',
    module: {
      exprContextCritical: false,
        rules: [
          {
            test: /\.tsx?$/,
            use: ['@ibyar/cli',],
            exclude: /node_modules/,
          }
        ]
      }
};

use `ts-loader`

// 1. import default from the plugin module
import {
	beforeCompileDirectiveOptions, beforeCompileComponentOptions,
	afterDeclarationsCompileComponentOptions,
	afterDeclarationsCompileDirectiveOptions,
	scanDirectivesOnceAsTransformer,
} from '@ibyar/cli';


// 3. add getCustomTransformer method to the loader config
var config = {
    ...
    module: {
        rules: [
            {
                test: /\.tsx?$/,
                loader: 'ts-loader',
                options: {
                    ... // other loader's options
                    getCustomTransformers: () => ({
						before: [
							scanDirectivesOnceAsTransformer(),
							beforeCompileDirectiveOptions,
							beforeCompileComponentOptions,
						],
						after: [],
						afterDeclarations: [
							afterDeclarationsCompileComponentOptions,
							afterDeclarationsCompileDirectiveOptions,
						],
					})
                }
            }
        ]
    }
    ...
};

Integration with `Rollup`

import typescript from '@rollup/plugin-typescript';
import {
	beforeCompileDirectiveOptions, beforeCompileComponentOptions,
	afterDeclarationsCompileComponentOptions,
	afterDeclarationsCompileDirectiveOptions,
	scanDirectivesOnceAsTransformer,
} from '@ibyar/cli';

export default = {
	...,
	plugins: [
