- ⌨️ Builds a UX-rich component (e.g. and keyword support) via comprehensive .
- 🦔 Tiny size (). No external dependencies, aside for the react.
How does it work?
First, use the script tag to load the library in your project.<script src="//maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>import usePlacesAutocomplete, {
getGeocode,
getLatLng,
} from "use-places-autocomplete";
import useOnclickOutside from "react-cool-onclickoutside";
const PlacesAutocomplete = () => {
const {
ready,
value,
suggestions: { status, data },
setValue,
clearSuggestions,
} = usePlacesAutocomplete({
requestOptions: {
/* Define search scope here */
},
debounce: 300,
});
const ref = useOnclickOutside(() => {
// When user clicks outside of the component, we can dismiss
// the searched suggestions by calling this method
clearSuggestions();
});
const handleInput = (e) => {
// Update the keyword of the input element
setValue(e.target.value);
};
const handleSelect =
({ description }) =>
() => {
// When user selects a place, we can replace the keyword without request data from API
// by setting the second parameter to "false"
setValue(description, false);
clearSuggestions();
// Get latitude and longitude via utility functions
getGeocode({ address: description }).then((results) => {
const { lat, lng } = getLatLng(results[0]);
console.log("📍 Coordinates: ", { lat, lng });
});
};
const renderSuggestions = () =>
data.map((suggestion) => {
const {
place_id,
structured_formatting: { main_text, secondary_text },
} = suggestion;
return (
<li key={place_id} onClick={handleSelect(suggestion)}>
<strong>{main_text}</strong> <small>{secondary_text}</small>
</li>
);
});
return (
<div ref={ref}>
<input
value={value}
onChange={handleInput}
disabled={!ready}
placeholder="Where are you going?"
/>
{/* We can use the "status" to decide whether we should display the dropdown or not */}
{status === "OK" && <ul>{renderSuggestions()}</ul>}
</div>
);
};
Easy right? This is the magic of the usePlacesAutocomplete ✨. I just show you how does it work via the minimal example. However there're more things you can do for an UX rich autocomplete component, like and keyword support as my (check the ), a keyword clear button, search history etc.
💡 is my other hook library, which can help you handle the interaction of user clicks outside of the component(s).
