Best node.js module for finding location? [closed]

问题

I had found couple of node.js modules for finding the information about client location and network using ip address.

Requirements:

Location - country, city, state, latitude, longitude etc.
Network - Internet service Provider, Internet connection type and internet speed etc.
Data Accuracy - maximum possibility.

Note: Looking for server side solution.

The above mentioned modules uses maxmind data. And i had read about the maxmind data accuracy as well.

I am little confused to choose the above node.js modules and i like to know is there any better node.js frameworks available for finding information which met my requirement or any other language plugins which can be portable to node.js.

Any idea will be greatful.

Using IP-based geolocation is possible, but not very accurate. So I suggest you to think about going with a hybrid approach, like trying to get the users location via the HTML5 geolocation API inside the browser and fallback to the serverside if necessary.

I took a look at the two most used geoip/-location modules available for node.js and they both use the datasets provided by MaxMind. AFAIK you have to keep these databases up-2-date manually, which is a clear downer. So you may consider writing a little sync service / script, which updates the database once per month. (More information on MaxMinds free solution can be found here).

kuno/GeoIP is a GeoIP binding, so at it's core it's using the libGeoIP C library, which is okay, but maybe not as portable as the pure JavaScript implementation bluesmoon/node-geoip offers. Both are okay and it's up to you which library you like more. In terms of performance you have to do some benchmakrs (if this topic matters to you) … There is no general answer to the question, which type of module (C-binding/native) will be faster.

If you're willing to spend a few bucks you could also look into MaxMinds Web Service, which is a simple REST API and will be the most precise way to go. The documentation is quite good – so getting started with that won't be a problem.

If you get the IP, you can always call an external service to get the location information such as freegeoip.net and using the request module.

(ip, location) ->
  url = 'http://freegeoip.net/json/' + ip
  request.get url, (error, response, body) ->
    if !error && response.statusCode == 200
      data = JSON.parse body
      location data

For the network infos, I don't have a solution, but I'm looking for one too.

You can get all of the information you're after from my API at http://ipinfo.io API:

$ curl ipinfo.io
{
  "ip": "67.188.232.131",
  "hostname": "c-67-188-232-131.hsd1.ca.comcast.net",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "loc": "37.4192,-122.0574",
  "org": "AS7922 Comcast Cable Communications, Inc.",
  "postal": "94043"
}

It supports JSONP and CORS, so you can use it either server or client side. More details are available at http://ipinfo.io/developers
