My prime motivator was the fact that it was really hard to get libgeoip built for Mac OSX without using the library from MacPorts. -🕵️‍♂️ Why GeoIP-Lite? ------------------- +## 🕵️‍♂️ Why GeoIP-Lite? GeoIP-Lite is a fully JavaScript implementation of the MaxMind GeoIP API. It is not as fully featured as bindings that use `libgeoip`. By reducing scope, this package is about 40% faster at doing lookups. On average, an IP to Location lookup should take 20 microseconds on a Macbook Pro. IPv4 addresses take about 6 microseconds, while IPv6 addresses take about 30 microseconds. -📝 Synopsis ------------- +## 📝 Synopsis ### Script ```javascript const geoIp2 = require('geoip-lite2'); @@ -102,8 +95,7 @@ console.log(geo); ``` -🛠️ Installation ----------------- +## 🛠️ Installation ### 1.
