svelte-google-places-autocomplete

A minimal port of the Google Places Autocomplete API as a Svelte component.

Inspired largely by beyonk-adventures/svelte-googlemaps.

Google API Restrictions

If you restrict the Google API key you use for this (recommended), ensure you allow at least the following two APIs, since this component needs them in order to fully function:

• Maps JavaScript API
• Places API

Example usage

<script>
const options = {
  fields: ['address_components', 'geometry'],
  types: ['(cities)']
}
const placeholder = 'Destination city'

let locationName = localStorage.get('locationName') || ''
</script>

<GooglePlacesAutocomplete apiKey={googlePlacesApiKey} class="form-control"
                          on:place_changed={onPlaceChanged} {options}
                          on:ready={onReady} {placeholder}
                          value={locationName}
                          required
                          pattern="[a-zA-Z ]+" />

Parameters

apiKey

Your Google Places API Key.

class

Any HTML class string to apply to the input element.

options

The options that you want to pass to the Google Places Autocomplete code.

Details: https://developers.google.com/maps/documentation/javascript/reference/places-widget#AutocompleteOptions

placeholder

Any placeholder text to use. Defaults to an automatically-localized placedholder string.

value

The text to show in the input.

WARNING: You cannot bind to this. To receive data out of this component, listen for the place_changed event.

required

Require a value to be entered.

pattern

Specifies a regular expression that is used for validation upon form submission.

Events

place_changed

When a location is selected,

ready

Fired when the component has initialized, the Google Places API has been loaded, and this component is therefore ready for user interaction.

Tests

Running the tests

(Mostly) automated tests are available:

1. Run make test
2. Open localhost:8086 in a browser
3. Paste in your Google Places API Key and hit Enter
4. Follow any instructions shown (e.g. "Please click on the first suggestion")

Modifying the tests

The tests are defined in test/tests.js. See that file for examples.
