📖 How to Use

1️⃣ Basic Usage

import React from "react";
import GooglePlacesAutocomplete from "google-places-autocomplete-react";

const App = () => {
    const handlePlaceSelect = (place) => {
        console.log("Selected Place:", place);
    };

    return (
        <div style={{ maxWidth: "400px", margin: "50px auto" }}>
            <GooglePlacesAutocomplete 
                apiKey="YOUR_GOOGLE_API_KEY"
                onPlaceSelect={handlePlaceSelect}
            />
        </div>
    );
};

export default App;

2️⃣ Fetching Place Details

The onPlaceSelect callback receives an object containing:

• description - The name of the selected place.
• lat - Latitude of the location.
• lng - Longitude of the location.

Example:

const handlePlaceSelect = (place) => {
    console.log("Place Name:", place.description);
    console.log("Latitude:", place.lat);
    console.log("Longitude:", place.lng);
};

3️⃣ Customizing Placeholder Text

<GooglePlacesAutocomplete 
    apiKey="YOUR_GOOGLE_API_KEY"
    onPlaceSelect={handlePlaceSelect}
    placeholder="Enter a city or address"
/>

4️⃣ TypeScript Usage

This package includes full TypeScript support with type definitions:

import React from "react";
import GooglePlacesAutocomplete, { 
    PlaceDetails, 
    GooglePlacesAutocompleteProps 
} from "google-places-autocomplete-react";

const App: React.FC = () => {
    const handlePlaceSelect = (place: PlaceDetails) => {
        console.log("Selected Place:", place);
        // place.description - string
        // place.lat - number  
        // place.lng - number
    };

    const props: GooglePlacesAutocompleteProps = {
        apiKey: "YOUR_GOOGLE_API_KEY",
        onPlaceSelect: handlePlaceSelect,
        placeholder: "Search for a location...",
        inputClassName: "my-input"
    };

    return (
        <div>
            <GooglePlacesAutocomplete {...props} />
        </div>
    );
};

5️⃣ Styling and Customization

This component allows full customization via props and CSS:

<GooglePlacesAutocomplete
    apiKey="YOUR_GOOGLE_API_KEY"
    onPlaceSelect={handlePlaceSelect}
    inputClassName="custom-input"
    suggestionsClassName="custom-suggestions"
    suggestionItemClassName="custom-suggestion-item"
    inputStyle={{ 
        padding: "12px", 
        fontSize: "16px",
        border: "2px solid #e1e5e9",
        borderRadius: "8px",
        width: "100%"
    }}
    suggestionsStyle={{ 
        backgroundColor: "white", 
        borderRadius: "8px",
        boxShadow: "0 4px 6px rgba(0,0,0,0.1)",
        border: "1px solid #e1e5e9"
    }}
    suggestionItemStyle={{ 
        padding: "12px", 
        cursor: "pointer",
        borderBottom: "1px solid #f0f0f0"
    }}
/>

6️⃣ Advanced Example with Error Handling

import React, { useState } from "react";
import GooglePlacesAutocomplete from "google-places-autocomplete-react";

const LocationPicker = () => {
    const [selectedPlace, setSelectedPlace] = useState(null);
    const [error, setError] = useState("");

    const handlePlaceSelect = (place) => {
        try {
            setSelectedPlace(place);
            setError("");
            
            // You can now use the coordinates
            console.log(`Location: ${place.description}`);
            console.log(`Coordinates: ${place.lat}, ${place.lng}`);
            
            // Example: Save to local storage
            localStorage.setItem('selectedPlace', JSON.stringify(place));
            
        } catch (err) {
            setError("Failed to process selected location");
            console.error(err);
        }
    };

    return (
        <div style={{ maxWidth: "500px", margin: "20px auto", padding: "20px" }}>
            <h2>Select Your Location</h2>
            
            <GooglePlacesAutocomplete
                apiKey={process.env.REACT_APP_GOOGLE_API_KEY}
                onPlaceSelect={handlePlaceSelect}
                placeholder="Enter your address or location..."

                    fontSize: "16px",
                    border: error ? "2px solid red" : "2px solid #ddd",

                    marginTop: "5px"
                }}
            />
            
            {error && (
                <p style={{ color: "red", marginTop: "10px" }}>{error}</p>
            )}
            
            {selectedPlace && (
                <div style={{ 
                    marginTop: "20px", 
                    padding: "15px", 
                    backgroundColor: "#f8f9fa",

                    <p><strong>Address:</strong> {selectedPlace.description}</p>
                    <p><strong>Latitude:</strong> {selectedPlace.lat}</p>
                    <p><strong>Longitude:</strong> {selectedPlace.lng}</p>

🌎 Google API Setup

To use this package, you need a Google API key with the Places API enabled.

Steps to Get an API Key:

1. Go to the Google Cloud Console.
2. Create a new project or select an existing one.
3. Enable the Places API under "APIs & Services".
4. Generate an API key under "Credentials".
5. Restrict the key for security (optional).
6. Use the key in the apiKey prop.

🚀 Performance Optimization

Debouncing API Calls

For better performance and to avoid hitting API limits, consider debouncing the input:

import { useMemo, useCallback } from "react";
import { debounce } from "lodash";

const OptimizedLocationPicker = () => {
    // Debounce the place selection to avoid excessive API calls
    const debouncedPlaceSelect = useMemo(
        () => debounce((place) => {
            console.log("Selected:", place);
            // Your logic here
        }, 300),
        []
    );

    return (
        <GooglePlacesAutocomplete
            apiKey="YOUR_API_KEY"
            onPlaceSelect={debouncedPlaceSelect}
        />
    );
};

Environment Variables

Always use environment variables for API keys:

// .env file
REACT_APP_GOOGLE_API_KEY=your_actual_api_key_here

// In your component
<GooglePlacesAutocomplete
    apiKey={process.env.REACT_APP_GOOGLE_API_KEY}
    onPlaceSelect={handlePlaceSelect}
/>

Memory Management

The component automatically manages the Google Maps script loading and prevents duplicate script tags.

🛠 Troubleshooting & Error Handling

Common Issues and Solutions

1️⃣ Autocomplete not working?

Possible causes:

• Places API not enabled
• Invalid API key
• CORS issues
• Billing not set up

Solutions:

// Add error handling to your component
const [apiError, setApiError] = useState("");

useEffect(() => {
    // Check if Google Maps loaded successfully
    const checkGoogleMaps = () => {
        if (!window.google) {
            setApiError("Google Maps API failed to load. Check your API key.");
        }
    };
    
    setTimeout(checkGoogleMaps, 3000);
}, []);

2️⃣ TypeScript Errors

If you're getting TypeScript errors, make sure you have the latest version:

npm install google-places-autocomplete-react@latest

3️⃣ API Quota Exceeded

Monitor your usage:

const handlePlaceSelect = (place) => {
    try {
        // Your place handling logic
        console.log("API call successful:", place);
    } catch (error) {
        if (error.message.includes("OVER_QUERY_LIMIT")) {
            console.error("API quota exceeded. Check your billing settings.");
        }
    }
};

4️⃣ Network Issues

Add network error handling:

const [isLoading, setIsLoading] = useState(false);
const [networkError, setNetworkError] = useState("");

const handlePlaceSelect = async (place) => {
    setIsLoading(true);
    setNetworkError("");
    
    try {
        // Process the place data
        await processPlace(place);
    } catch (error) {
        setNetworkError("Network error. Please check your connection.");
    } finally {
        setIsLoading(false);
    }
};

5️⃣ Console Warnings

Common warnings and fixes:

| Warning | Solution | |---------|----------| | Google Maps API loaded multiple times | The component handles this automatically | | API key not provided | Ensure your API key is correctly set | | Places service not available | Check if Places API is enabled |

Best Practices

1. Always validate the API key before deploying to production
2. Set up proper error boundaries in your React app
3. Monitor API usage to avoid unexpected charges
4. Use environment variables for sensitive data
5. Implement loading states for better UX
