Getting Started

To use this component, you are going to need to load Google Maps JavaScript API

Load the library in your project

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>

Declare your PlacesAutocomplete component using React component

import React from 'react'
import PlacesAutocomplete, { geocodeByAddress } from 'react-places-autocomplete'

class SimpleForm extends React.Component {
  constructor(props) {
    super(props)
    this.state = { address: 'San Francisco, CA' }
    this.onChange = (address) => this.setState({ address })
  }

  handleFormSubmit = (event) => {
    event.preventDefault()

    geocodeByAddress(this.state.address,  (err, latLng) => {
      if (err) { console.log('Oh no!', err) }

      console.log(`Yay! Got latitude and longitude for ${address}`, latLng)
    })
  }

  render() {
    const inputProps = {
      value: this.state.address,
      onChange: this.onChange,
    }

    return (
      <form onSubmit={this.handleFormSubmit}>
        <PlacesAutocomplete inputProps={inputProps} />
        <button type="submit">Submit</button>
      </form>
    )
  }
}

export default SimpleForm

Props for `PlacesAutocomplete`

Require Props:

inputProps

Optional Props:

inputProps

Type: Object, Required: true

PlacesAutocomplete is a controlled component. Therefore, you MUST pass at least value and onChange callback to the input element.

You can pass arbitrary props to the input element thorough inputProps object (NOTE: className and style props for the input element should be passed through classNames.input and styles.input respectively).

  const inputProps = {
    value, // `value` is required
    onChange, // `onChange` is required
    onBlur: () => {
      console.log('blur!')
    },
    type: 'search',
    placeholder: 'Search Places...',
    autoFocus: true,
  }

autocompleteItem

Type: Functional React Component, Required: false

The function takes props with suggestion, formattedSuggestion keys (see the example below). We highly recommend that you create your own custom AutocompleteItem and pass it as a prop.

/***********************************************
 Example #1
 autocompleteItem example with `suggestion`
************************************************/
render() {
  const AutocompleteItem = ({ suggestion }) => (<div><i className="fa fa-map-marker"/>{suggestion}</div>)

  return (
    <PlacesAutocomplete
      inputProps={inputProps}
      autocompleteItem={AutocompleteItem}
    />
  )
}

/***************************************************
 Example #2
 autocompleteItem example with `formattedSuggestion`
****************************************************/
render() {
  const AutocompleteItem = ({ formattedSuggestion }) => (
    <div>
      <strong>{ formattedSuggestion.mainText }</strong>{' '}
      <small>{ formattedSuggestion.secondaryText }</small>
    </div>
  )

  return (
    <PlacesAutocomplete
      inputProps={inputProps}
      autocompleteItem={AutocompleteItem}
    />
  )
}

classNames

Type: Object, Required: false

You can give a custom css classes to elements. Accepted keys are root, input, autocompleteContainer, autocompleteItem, autocompleteItemActive. If you pass classNames props, none of the default inline styles nor inline styles from styles prop will be applied to the element, and you will have full control over styling via CSS.

// classNames example
render() {
  const cssClasses = {
    root: 'form-group',
    input: 'form-control',
    autocompleteContainer: 'my-autocomplete-container'
  }

  return (
    <PlacesAutocomplete
      inputProps={inputProps}
      classNames={cssClasses}
    />
  )
}

Now you can easily apply custom CSS styles using the classNames!

styles

Type Object, Required: false

You can provide custom inline styles to elements. Accepted keys are root, input, autocompleteContainer, autocompleteItem, autocompleteItemActive.

const defaultStyles = {
  root: {
    position: 'relative',
    paddingBottom: '0px',
  },
  input: {
    display: 'inline-block',
    width: '100%',
    padding: '10px',
  },
  autocompleteContainer: {
    position: 'absolute',
    top: '100%',
    backgroundColor: 'white',
    border: '1px solid #555555',
    width: '100%',
  },
  autocompleteItem: {
    backgroundColor: '#ffffff',
    padding: '10px',
    color: '#555555',
    cursor: 'pointer',
  },
  autocompleteItemActive: {
    backgroundColor: '#fafafa'
  }
}

Object passed via styles prop will be merged in with the above defaults and applied to their respective elements. NOTE: Passing classNames will disable any inline styling for respective elements.

// custom style examples
render() {
  const myStyles = {
    root: { position: 'absolute' },
    input: { width: '100%' },
    autocompleteContainer: { backgroundColor: 'green' },
    autocompleteItem: { color: 'black' },
    autocompleteItemActive: { color: 'blue' }
  }

  return (
    <PlacesAutocomplete
      inputProps={inputProps}
      styles={myStyles}
    />
  )
}

onError

Type: Function Required: false

You can pass onError prop to customize the behavior when google.maps.places.PlacesServiceStatus is not OK (e.g., no predictions are found)

Function takes status as a parameter

clearItemsOnError

Type: Boolean Required: false Default: false

You can pass clearItemsOnError prop to indicate whether the autocomplete predictions should be cleared when google.maps.places.PlacesServiceStatus is not OK

onSelect

Type: Function Required: false, Default: null

You can pass a function that gets called instead of onChange function when user hits the Enter key or clicks on an autocomplete item.

The function takes two positional arguments. First argument is address, second is placeId.

const handleSelect = (address, placeId) => {
  this.setState({ address, placeId })

  // You can do other things with address string or placeId. For example, geocode :)
}

// Pass this function via onSelect prop.
<PlacesAutocomplete
  inputProps={inputProps}
  onSelect={this.handleSelect}
/>

onEnterKeyDown

Type: Function Required: false Deafult: noop

You can pass a callback function that gets called when pressing down Enter key when no item in the dropdown is selected.
The function takes one argument, the value in the input field.

const handleEnter = (address) => {
  geocodeByAddress(address, (err, { lat, lng }, results) => {
    if (err) { console.error('Error'); return; }

    console.log("Geocode success", { lat, lng })
  })
}

// Pass this function via onEnterKeyDown prop.
<PlacesAutocomplete
  inputProps={inputProps}
  onEnterKeyDown={this.handleEnter}
/>

options

Type: Object Required: false Default: {}

You can fine-tune the settings passed to the AutocompleteService class with options prop. This prop accepts an object following the same format as google.maps.places.AutocompletionRequest (except for input, which comes from the value of the input field).

// these options will bias the autocomplete predictions toward Sydney, Australia with a radius of 2000 meters,
// and limit the results to addresses only
const options = {
  location: new google.maps.LatLng(-34, 151),
  radius: 2000,
  types: ['address']
}

<PlacesAutocomplete
  inputProps={inputProps}
  options={options}
/>
