node-geoip-middleware

GeoIP middleware for Connect/Express. Can be used with geoip, geoip-static or any service that has a lookup(ip, callback) method.

Install

With npm do

npm install geoip-middleware

Usage

middleware(options)

• options.db GeoIP db instance.
• options.fields Extracted fields from geoip result. Defaults to ['country_code', 'continent_code]'.
• options.cache Cache result (requires session support), defaults to true.
• options.strict When lookup fails, handle it as an error. By default, errors are silently dropped, and the defaultss value is used.
• options.defaults Default values, when lookup fails. Defaults: { country_code: 'US', continent_code: 'NA' }.
