Fix: @connect decorator

[obsofficer-ctrl]

Summary

This PR addresses: #68

Task: @connect decorator
Platform: github

Changes

Looking at this repository, I need to add documentation/examples showing how to use the @connect(..) decorator syntax with React, Redux, and TypeScript.

Let me analyze the repository structure:

1. It's a guide repository where README_SOURCE.md contains the documentation
2. Code examples are in the playground/src/ folder
3. The generate-readme.js script injects code from playground files into the README

I need to:

1. Create example files in the playground showing @connect decorator usage
2. Update README_SOURCE.md to reference these examples

Let me create the connect decorator example files:

import React, { Component } from 'react';
import { connect } from 'react-redux';
import { bindActionCreators, Dispatch } from 'redux';
import { RootState } from '../store/types';
import { countersActions } from '../features/counters';
import { hotelsActions } from '../features/hotels';

// Props that come from the parent component
interface OwnProps {
  label: string;
}

// Props from Redux state (mapStateToProps)
interface StateProps {
  count: number;
}

// Props from Redux dispatch (mapDispatchToProps)
interface DispatchProps {
  onIncrement: () => void;
  onDecrement: () => void;
}

// All component props combined
type Props = OwnProps & StateProps & DispatchProps;

// Map Redux state to component props
const mapStateToProps = (state: RootState, ownProps: OwnProps): StateProps => ({
  count: state.counters.reduxCounter,
});

// Map Redux dispatch to component props
const mapDispatchToProps = (dispatch: Dispatch): DispatchProps =>
  bindActionCreators(
    {
      onIncrement: countersActions.increment,
      onDecrement: countersActions.decrement,
    },
    dispatch
  );

// Using the @connect decorator syntax
@connect(mapStateToProps, mapDispatchToProps)
class ConnectedCounter extends Component<Props> {
  render() {
    const { label, count, onIncrement, onDecrement } = this.props;
    return (
      <div

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the guide by providing concrete examples and necessary configuration for integrating the @connect decorator with React, Redux, and TypeScript. It addresses a specific issue by adding new code examples that illustrate this pattern, making it easier for users to understand and implement.

Highlights

• New Decorator Examples: New example files were introduced to demonstrate the use of the @connect decorator syntax with React, Redux, and TypeScript.
• TypeScript Configuration Update: The tsconfig.json was updated to enable experimentalDecorators, a prerequisite for using TypeScript decorators.
• New Redux Module: A new Redux module for counter actions and state was added to support the examples.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

Code Review

This pull request introduces examples for using the @connect decorator with React, Redux, and TypeScript. New files are added to the playground to demonstrate this, including necessary configuration changes in tsconfig.json. The changes are a valuable addition. I've left a couple of comments on one of the new example files to address an unused import and an unused function parameter for better code quality and consistency.

[gemini-code-assist]

The hotelsActions import is not used in this file and should be removed to maintain code cleanliness.

[gemini-code-assist]

The ownProps parameter is declared but never used within the mapStateToProps function. To improve code clarity and signal that this is intentional, it's best practice to prefix unused variables with an underscore.

Suggested change

	const mapStateToProps = (state: RootState, ownProps: OwnProps): StateProps => ({
	const mapStateToProps = (state: RootState, _ownProps: OwnProps): StateProps => ({
