Package Exports

react-places-autocomplete

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-places-autocomplete) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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 })
    this.handleFormSubmit = this.handleFormSubmit.bind(this)
  }

  handleFormSubmit(event) {
    event.preventDefault()
    const { address } = this.state

    geocodeByAddress(address,  (err, { lat, lng }) => {
      if (err) {
        console.log('Oh no!', err)
      }

      console.log(`Yay! got latitude and longitude for ${address}`, { lat, lng })
    })
  }

  render() {
    return (
      <form onSubmit={this.handleFormSubmit}>
        <PlacesAutocomplete
          value={this.state.address}
          onChange={this.onChange}
        />
        <button type="submit">Submit</button>
      </form>
    )
  }
}

export default SimpleForm

Props for `PlacesAutocomplete`

value

Type: String, Required: true

Value displayed in the input field

onChange

Type: Function, Required: true

Please see the example above

autocompleteItem

Type: Functional React Component, Required: false

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

// autocompleteItem example (with font-awesome icon)
render() {
  const AutocompleteItem = ({ suggestion }) => (<div><i className="fa fa-map-marker"/>{suggestion}</div>)

  return (
    <PlacesAutocomplete
      value={this.state.value}
      onChange={this.onChange}
      autocompleteItem={AutocompleteItem}
    />
  )
}

classNames

Type: Object, Required: false

You can give a custom css classes to elements. Accepted keys are root, label, input, autocompleteContainer

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

  return (
    <PlacesAutocomplete
      value={this.state.address}
      onChange={this.onChange}
      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, label, input, autocompleteContainer, autocompleteItem, autocompleteItemActive

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

  return (
    <PlacesAutocomplete
      value={this.state.address}
      onChange={this.onChange}
      styles={myStyles}
    />
  )
}

placeholder

Type: String, Required: false, Default: "Address"

You can pass placeholder prop to customize input's placeholder text

hideLabel

Type: Boolean Required: false, Default: false

You can set hideLabel to true to not render the label element

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.

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
  value={this.state.address}
  onChange={this.onChange}
  options={options}
/>

`geocodeByAddress` API

geocodeByAddress(address, callback)

address

Type: String, Required: true

callback

Type: Function, Required: true

Two arguments will be passed to the callback.

First argument is an error object, set to null when there's no error.
