Understanding customers and running a smooth business are two of the major specialties of Salesforce. When the sales and marketing team faced challenges in assigning territories, finding nearby prospects, campaigning on a particular location and more such geolocation activities, Salesforce unlocked a whole new way into this world of navigation.
Winter 19 introduced many components including lightning:map which is very useful for developers. Before lightning:map, the developers needed Google API key and lots of script to show address on the Google Map. The lightning:map component displays a map of one or more locations using Google Maps securely.
This component requires API version 44.0, making it easy to display the user location in the UI. There is no need to use external JavaScript libraries anymore. Developers can use markers in the component to define location on the map wherein the marker could be a pair of coordinates (latitude and longitudes), or a set of address elements such as Street, City, State, Country or Postal Code.
