It is non-blocking and operates without any IO after initially loading the data into memory.
Results are 4 - 5 times faster than geoip-lite with the caveat that it takes 2 or 3 times longer to initialize and uses 60 or 70 megabytes memory.
Benchmarks on my 2011 Macbook Air whilst running lots of software. The test took the middle 10 results from 20 iterations and averaged them. The APIs are interchangeable so tests were identical.
geoip-native: average: 1540.3ms / million lookups geoip-lite: average: 8375.3ms / million lookups
npm install geoip-native
Node GeoIP Native provides methods for:
lookupperforms the lookup, takes the ip address as a parameter
var geoip = require("geoip-native"); var ip = "18.104.22.168"; geoip.lookup(ip); console.log("country: " + ip.name + " / " + ip.code); // in practice you'd want: // ip = request.headers["x-forwarded-for"] || request.connection.remoteAddress,
Be neat to expand this to include cities.
