Caffeinate me! Build a serverless app to find the nearest Starbucks.

0

If you build mobile apps or any location-aware software, you’ll quickly come across a difficult problem — how to locate the ‘nearest’ or ‘furthest’ of something.

Fortunately, there is a public domain geocoding solution to this problem called geohashing. In this article on A Cloud Guru, I previously explained how to use this to build out a back-end geo-search solution. In this project, we are going to use that approach to create a web app front-end that can help you find all the Starbucks locations within walking distance.
