geo-ip-service v0.1.1

Geo IP lookup service

TLDR HTTP Middleware to look up geo information by IP. Using maxmind's binary database format.

Usually we run this as a microservice and expose to other services that want to dynamically fetch it, getting a blazing fast results due to cache usage, rather than installing it in every project which might need it.

Project

Instalation:

npm install --save geo-ip-service

Usage:

Package exports 3 modules

• iplookup (an initialized Reader if you want to use it directly in your code by giving it an IPv4 or IPv6 address)
• getMiddleware (a factory function if you want to mount it to your existing server application as a middleware, see examples/)
• createServer (if you want to simply run it as individual http service, see example/native-http.js)

Updating using postinstall script:

• if you provide it with a MAXMIND_LICENSE_KEY in env vars, a postinstall script will update the database with the latest one from maxmind servers. In case that headers from maxminds origin server Last Modified matches state on disk, it will skip download, so you don't get downloads happening on repeated npm installs
