Let's go back to and check the NodeJS code from their page. We already executed a Lambda function in our machine successfully, that is good, really good. Setup the project like in the folowing screenshot:Įxec sam local invoke and this will execute the default from template.yml so you should see the following output(Note: you need Docker in your machine): Navigate to your dev playground folder and exec sam init. Whenever you have SAM working in your machine, follow these steps. Since installing SAM and getting started with it is out of scope for this post, you may follow the official doc to do that Though SAM is oriented towards offering full REST capabilities in order to build a whole application, we will only use it to manage, invoke and deploy a Lambda function. SAM allows us to build and deploy serverless applications with little effort. Learn about GeoIP databases and services and minFraud services. Now let's check the usage for NodeJS of their APIs at, do not worry, we will spare a few lines of code in few moments. MaxMind is a leading provider of IP intelligence and online fraud prevention tools. Locate the file 'GeoLite2-City.mmdb' to be able to use it later. Follow instructions in the URL above and download 'GeoLite2 City':

To accomplish this goal we will make use of the following technologies/services:įirst of all, Maxmind ( ) offers us a group of free GeoIP (capped) databases to play with.

Let's be clear about the final goal: 'My own endpoint which will receive an IP as query parameter and it will return location info such as country and city'. There so much literature about using GeoIP third party services, but if you really like to play and test a DIY GeoIP endpoint to use in your projects, follow me across two posts and let's check how to do it. The geoip processor adds information about the geographical location of IP addresses, based on data from the Maxmind GeoLite2 City Database. There are free and paid versions of geoip database available. This is not a start-from-subzero tutorial, so you will need a few things installed and working on your machine before starting this first post: Our module uses GeoIP2 City database provided by MaxMind company.
