Creating an instance

You can obtain a Google API key here.

const places = new GPlaces({

});

Search for places

places.search('nemo', {
  components: 'country:nl',
  types: 'establishment'
})
  .then(r => {
    // returns ACResult[]
  })
  .catch(console.error)

Search for places nearby

places.searchNearby('brussel', 2500, {
  components: 'country:be',
  types: '(cities)'
})
  .then(r => {
    // returns ACResult[]
  })
  .catch(console.error)

Get details for a Place

places.getPlaceDetails('ChIJn8N5VRvZxkcRmLlkgWTSmvM', {
  fields: 'geometry'
})
  .then(r => {
    // returns PDResult
  })
  .catch(console.error)
