koa-geo-ip

Uses ip to geolocate requests

Getting Started

npm i koa-geo-ip

Example

Example using as koa middleware

var geo = require( 'koa-geo-ip' );

app.use( function* () {
  this.body = this.geo;
});

app.listen( 3000 );

Example using co to access the generator

var co = require( 'co' );
var geoip = require( 'koa-geo-ip' );
var geolocate = geoip();

co( function *() {
  var location = {
    ip: '8.8.8.8'
  };
  yield gg.call( location );
  return location.geo;
})
  .then( function( loc ) {
    console.log( loc );
  });

The db path can also be specified using the package.json, see this repo’s package for an example. Both the install script and the module will use the package info if run via npm, otherwise specify the path.

Install Script

Included is a quick script to download the database, by default it’ll use the path specified in the package.json if run via npm, use --db to specify a path.
