Pros of Weex

• More active development and frequent updates
• Larger community and ecosystem support
• Better documentation and examples for developers

Cons of Weex

• Less focus on Apache Software Foundation governance
• Potential for divergence from the incubator version
• May have more proprietary features specific to Alibaba's needs

Code Comparison

incubator-weex:

const modal = weex.requireModule('modal')
modal.alert({
  message: 'This is an alert',
  okTitle: 'OK'
})

Weex:

const modal = weex.requireModule('modal')
modal.alert({
  message: 'This is an alert',
  okTitle: 'OK',
  callback: () => console.log('Alert closed')
})

The main difference in this example is the addition of a callback function in the Weex version, which provides more flexibility for handling user interactions.

Summary

While both repositories aim to develop the Weex framework, the Alibaba-maintained version (Weex) tends to be more actively developed and has a larger community. However, the Apache incubator version (incubator-weex) may adhere more strictly to open-source principles and Apache governance. Developers should consider their specific needs and preferences when choosing between the two repositories.

Pros of NativeScript

• More mature and stable project with a larger community and ecosystem
• Supports both Angular and Vue.js frameworks, offering more flexibility
• Better documentation and learning resources available

Cons of NativeScript

• Steeper learning curve, especially for developers new to mobile development
• Larger app size compared to Weex due to the inclusion of the entire runtime

Code Comparison

NativeScript (XML):

<Page>
  <StackLayout>
    <Label text="Hello, NativeScript!" />
    <Button text="Click me" tap="onButtonTap" />
  </StackLayout>
</Page>

Weex (Vue.js):

<template>
  <div>
    <text>Hello, Weex!</text>
    <wxc-button text="Click me" @wxcButtonClicked="onButtonTap"></wxc-button>
  </div>
</template>

Both frameworks allow developers to create native mobile applications using web technologies. NativeScript uses a custom XML-based markup language for defining UI, while Weex leverages Vue.js components. NativeScript provides a more native-like development experience, whereas Weex focuses on web-like development patterns.

NativeScript offers a wider range of supported platforms and better performance for complex applications. However, Weex has a gentler learning curve for web developers and potentially smaller app sizes for simpler applications.

Pros of React Native

• Larger community and ecosystem, with more third-party libraries and resources
• Better performance for complex UI interactions and animations
• More mature and stable, with longer development history

Cons of React Native

• Steeper learning curve, especially for developers new to React
• Larger app size due to bundled JavaScript runtime
• More frequent updates and potential breaking changes

Code Comparison

React Native:

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const App = () => (
  <View style={styles.container}>
    <Text>Hello, React Native!</Text>
  </View>
);

Weex:

<template>
  <div class="container">
    <text>Hello, Weex!</text>
  </div>
</template>

<style scoped>
.container { /* styles */ }
</style>

React Native uses JSX syntax and React components, while Weex uses a Vue-like template structure. React Native relies on StyleSheet for styling, whereas Weex uses scoped CSS-like styles. Both frameworks aim to provide a native-like experience, but their approach and syntax differ significantly.

Pros of Ionic Framework

• Larger and more active community, with more frequent updates and contributions
• Extensive documentation and learning resources available
• Supports multiple frameworks (Angular, React, Vue) for greater flexibility

Cons of Ionic Framework

• Larger bundle size and potentially slower performance compared to native apps
• Steeper learning curve for developers new to web technologies
• May require additional plugins for accessing certain native device features

Code Comparison

Weex (Vue.js component):

<template>
  <div>
    <text>{{ message }}</text>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello, Weex!'
    }
  }
}
</script>

Ionic Framework (Angular component):

import { Component } from '@angular/core';

@Component({
  selector: 'app-home',
  template: '<ion-content><h1>{{ message }}</h1></ion-content>'
})
export class HomePage {
  message = 'Hello, Ionic!';
}

Both frameworks allow for component-based development, but Ionic Framework provides more built-in UI components and integrates closely with popular web frameworks. Weex focuses on native rendering and performance, while Ionic emphasizes cross-platform compatibility and web standards.

Pros of Flutter

• More active development and larger community support
• Extensive documentation and learning resources
• Better performance for complex UI animations

Cons of Flutter

• Larger app size due to bundled runtime
• Steeper learning curve for developers new to Dart
• Limited access to native platform features without plugins

Code Comparison

Flutter (Dart):

import 'package:flutter/material.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Flutter App')),
        body: Center(child: Text('Hello, World!')),
      ),
    );
  }
}

Weex (Vue.js):

<template>
  <div>
    <text>Hello, World!</text>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

Flutter uses Dart and a widget-based approach for building UIs, while Weex leverages Vue.js and web technologies. Flutter's code tends to be more verbose but offers more control over UI elements. Weex's syntax is simpler and familiar to web developers, but may have limitations in complex UI scenarios.

Pros of React Native Windows

• Specifically designed for Windows platforms, offering better integration with Windows-specific features
• Larger and more active community, resulting in more frequent updates and better support
• Backed by Microsoft, ensuring long-term support and development

Cons of React Native Windows

• Limited to Windows platforms, reducing cross-platform compatibility compared to Weex
• Steeper learning curve for developers not familiar with Windows development
• Potentially larger app size due to Windows-specific dependencies

Code Comparison

React Native Windows:

import { NativeModules } from 'react-native-windows';

const { WindowsModule } = NativeModules;
WindowsModule.showNativeDialog('Hello from Windows!');

Weex:

const modal = weex.requireModule('modal');
modal.alert({
  message: 'Hello from Weex!',
  okTitle: 'OK'
});

Both frameworks allow for native module integration, but React Native Windows provides more Windows-specific functionality, while Weex focuses on cross-platform compatibility.

React Native Windows is ideal for developers targeting Windows platforms exclusively, offering deep integration with Windows features. Weex, on the other hand, provides a more versatile solution for cross-platform development, including mobile and web platforms. The choice between the two depends on the specific project requirements and target platforms.
