Introduction

A hapi plugin to geo locate requests by IP and provide request.location in your route handlers. The plugin uses ipinfo.io for the IP geo location.

Requirements

hapi v19 (or later) and Node.js v12 (or newer)

This plugin requires hapi v19 (or later) and Node.js v12 or newer.

Compatibility

Major Release	hapi.js version	Node.js version
v4	>=17 hapi	>=12
v3	>=17 hapi	>=8
v2	<=16 hapi	>=8

Installation

Add hapi-geo-locate as a dependency to your project:

npm i hapi-geo-locate

Using hapi v17 or v18?

Use the 3.x release line:

npm i hapi-geo-locate@3

Do you use hapi v16 (or lower)?

Use the 2.x release of hapi-geo-locate with hapi v16 support. Later versions are only compatible with hapi v17 and v18.

npm i hapi-geo-locate@2

Usage

The most straight forward way to register the hapi-geo-locate plugin:

await server.register({
    plugin: require('hapi-geo-locate')
})

// went smooth like dark chocolate :)

// Within your route handler functions, you can access the location like this
server.route({
    method: 'GET',
    path: '/',
    handler: (request, h) => {
        const location = request.location

        // use client location

        return location
    }
})

Plugin Registration Options

The following plugin options allow you to customize the default behavior of hapi-geo-locate:

• enabledByDefault: (boolean), default: true — by default, the plugin geo locates the request by IP on every request
• authToken: (string), no default — the API token to authenticate requests against the IPinfo API

await server.register({
  plugin: require('hapi-geo-locate'),
  options: {
    enabledByDefault: false
    authToken: 'your-ipinfo-api-token'
  }
})

// Within your route handler functions, you can access the location like this
server.route({
  method: 'GET',
  path: '/',
  handler: (request, h) => {
    const location = request.location // will be undefined

    return h.response(location)
  }
})

Route Handler Options

The following plugin options on individual route handlers allow you to customize the behavior of hapi-geo-locate:

• enabled: (boolean) — tells the plugin to enable (true) or disable (false) geo location for the request by IP
• fakeIP: (string) — tells the plugin to use the defined IP address to geo locate the request (by this IP)

The plugin configuration can be customized for single routes using the hapi-geo-locate key:

server.register({
  plugin: require('hapi-geo-locate') // enabled by default
})

// Within your route handler functions, you can access the location like this
server.route({
  method: 'GET',
  path: '/',
  handler: (request, h) => {
    const location = request.location
    // use the location

    return location
  },
  config: {
    plugins: {
      'hapi-geo-locate': {
        enabled: true,
        fakeIP: '8.8.8.8'
      }
    }
  }
})

Supported Proxies and Proxy Headers

hapi-geo-locate supports all proxies that request-ip does:

• X-Client-IP
• X-Forwarded-For, picking the first, client IP if the request went through multiple proxies.
• X-Forwarded, Forwarded-For and Forwarded as variations of X-Forwarded-For
• CF-Connecting-IP
• True-Client-Ip
• X-Real-IP
• X-Cluster-Client-IP
• and all the request.[connection|socket|info].remoteAddress variations.

If the IP address cannot be found, null is returned.

Running your application behind a (reverse) proxy like nginx, the client’s IP address gets reset to localhost. You can grab the actual request IP to your app using an HTTP header.

hapi-geo-locate uses the request-ip package to determine the external IP address. This package supports all common HTTP headers and ways to get the request’s IP. Awesome!

You should be safe in any way :)
