Seamless Cross-Platform Development with Universal HTML

Universal HTML is a revolutionary package that empowers developers with cross-platform compatibility for the HTML DOM API. It's a powerful tool that enables you to write code that seamlessly runs in browsers, mobile devices, desktops, and even Node.JS environments. By simply replacing your 'dart:html' imports with 'package:universal_html/html.dart,' you can eliminate the need for platform-specific code and enjoy the benefits of consistent development across various environments.

Benefits of Universal HTML

• Cross-platform Harmony: Develop code universally for browsers, mobile, desktop, and server-side VM, as well as Node.JS.
• DOM Manipulation Made Easy: Parse, navigate, and modify HTML and XML documents with ease using intuitive methods.
• CSS Query Support: Leverage CSS queries like 'querySelectorAll' to pinpoint DOM nodes for efficient manipulation.
• EventSource Streaming: Access EventSource (SSE) streaming capabilities, a crucial feature for real-time data transfer.

Getting Started

1. Add Dependency: Include universal_html in your 'pubspec.yaml' file:

dependencies:
  universal_html: ^2.2.4

2. Import and Use: Replace 'import 'dart:html;' with 'import "package:universal_html/html.dart";'

import 'package:universal_html/html.dart';

void main() {
  // Create DOM elements...
  // Manipulate DOM...
}

Examples

Parsing HTML:

import 'package:universal_html/parsing.dart';

void main() {
  final htmlDocument = parseHtmlDocument('...');
}

Parsing XML:

import 'package:universal_html/parsing.dart';

void main() {
  final xmlDocument = parseXmlDocument('...');
}

Scraping a Website:

import 'package:universal_html/controller.dart';

Future main() async {
  final controller = WindowController();
  await controller.openHttp(
    uri: Uri.parse("https://news.ycombinator.com/"),
    onRequest: (request) {
      // Set custom headers or cookies if needed...
    },
    onResponse: (response) {
      // Process the response...
    },
  );
}

EventSource Streaming:

import 'package:universal_html/html.dart';

Future main() async {
  final eventSource = EventSource('http://example.com/events');
  await for (var message in eventSource.onMessage) {
    // Process event...
  }
}

Testing:

import 'package:universal_html/controller.dart';
import 'package:test/test.dart';

void main() {
  setUp(() {
    WindowController.instance = WindowController();
  });

  test('test #1', () {
    // ...
  });
}

Conclusion

Universal HTML is an indispensable tool for developers who prioritize cross-platform compatibility and efficient HTML manipulation. Its versatility and ease of use make it a powerful solution for modern web and app development. Embrace Universal HTML and elevate your development experience!
