Build a location analytics reporting API in Node.js

Location analytics involves using geographic data, such as latitude and longitude, alongside other information to generate business insights, and its application has grown with the increased use of social media and mobile devices. This tutorial guides readers through creating a lightweight location analytics reporting service API using Node.js, focusing on error handling and proper file structure. It covers setting up the project environment, including necessary tools like Node.js, Express, and Git, and implementing features to handle HTTP requests for calculating distances based on IP addresses and coordinates. The tutorial also emphasizes the importance of error handling and validation, using tools such as Joi for schema validation and is-ip for IP address validation, and includes steps for testing the API with Postman. The result is a customizable API that businesses can use to enhance their service delivery by leveraging location data.
