Chapter 2. Discovering What's Nearby

When developing an application, we are often presented with the geolocation data for a particular point of interest. Whether it's a business location or a job that the end user is applying to, knowing what's around that particular location can provide immediate value to the user when making a decision about that location. For example, a user may want to know what restaurants are near a particular location or what public services or public transportation options are near a particular job the user is interested in. With the help of third-party location APIs, we can inform the user what is near a given point of interest. For our second application, we develop a web application that shows the user what is near a particular point of interest using information from the Google Places API. In this chapter, we also cover how to integrate third-party libraries into our application and how to improve the performance of our application with caching.
